Description

Method and device for responding to inquiries in asynchronous interaction

technical field

The invention relates to the technical field of asynchronous interaction, in particular to a technology for requesting equipment to respond to inquiries in asynchronous interaction.

Background technique

In the scenario of using asynchronous interaction, when the requester initiates a request to the requested party (such as the server), the server needs to generate data or query the database in real time. This process takes a certain amount of time, but the requesting party does not know where the server is. The corresponding request data can be generated.

In the prior art, a periodic polling method is often used to send an inquiry request to the server, such as sending a request to the server at regular intervals to inquire whether the data has been generated. In the process of server preparing data, if the number of interactions between the requester and the server is large, it will cause a large pressure load on the server. At the same time, the server cannot give corresponding feedback to the requester during the waiting process, making it impossible for the requester to predict the need to wait. time.

detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings.

The present invention aims to provide a method and device for responding to inquiries at the requesting device side in asynchronous interaction. Wherein, the requesting device that sends the query request and the requested device that receives the query request and provides a response may be any peer device that communicates in asynchronous interaction, for example, a user device that performs asynchronous loading and an asynchronous device that responds to the user device request to the web server.

The scheme of responding to inquiries in asynchronous interaction in the present invention can be realized by the requesting device or a specific device installed in the requesting device. Herein, for the convenience of description, the specific device is referred to as an inquiry device, which may be a hardware module with a hardware structure, or a software function module. Unless otherwise specified, in this document, the query device and the request device are used equally.

Fig. 1 is a flow chart of a method according to an embodiment of the present invention, which specifically shows a process for a requesting device to respond to an inquiry in an asynchronous interaction.

As shown in Figure 1, in step S1, after the requesting device sends a data request to the requested device, it determines the data request in the current response according to the reference response time corresponding to the requested device and the convergence query frequency of the query request during the current response waiting period. The request time point of each query request during the waiting period.

Here, the reference response time corresponding to the requested device means the reference response time for the requesting device to obtain the data response corresponding to the data request from the requested device; each response waiting period means that the requesting device sends The reference response time elapsed after a data request.

Wherein, the reference response time corresponding to the requested device may be determined based on at least any of the following:

1) The response time of the historical response obtained by the requesting device;

Here, the reference response time corresponding to the requested device may be determined based on the response time of historical responses obtained by the requesting device. Wherein, the historical responses obtained by the requesting device include historical responses obtained from the current requested device and historical responses obtained from other requested devices. A reference response time may be determined based on the response times of all or some of these historical responses. For example, the reference response time corresponding to the requested device may be the response time when it responded to the requesting device last time, or the response time when other requested devices responded to the requesting device last time. As another example, the reference response time corresponding to the requested device can be determined based on the response time of historical responses obtained by the requesting device within a period of time, such as the average value, maximum value or minimum value of the responses obtained in the latest time, and these responses can be It is limited to responses from the currently requested device, and may also include responses from other requested devices.

2) the expected response time provided by the requested device;

Here, the reference response time corresponding to the requested device may be determined based on the expected response time provided by the requested device. For example, after receiving the data request from the requesting device, the requested device can return an expected response time to the requesting device according to the type of data request, the current load status of the requested device, etc., and the expected response time can be used as the The corresponding reference response time; or, add or subtract a predetermined length of time on the basis of the expected response time, and use the increased or decreased time as the reference response time corresponding to the requested device.

3) The combination of the response time of historical responses obtained by the requesting device and the expected response time provided by the requested device.

Here, the reference response time corresponding to the requested device may be determined by combining the response time of historical responses obtained by the requesting device and the expected response time provided by the requested device. For example, the reference response time corresponding to the requested device may be set by selecting a longer or shorter time between the response time of the historical response obtained by the requesting device and the expected response time provided by the requested device.

Preferably, when the response time of the historical response obtained by the requesting device is greater than the expected response time provided by the requested device, the reference response time corresponding to the requested device is the difference between the two and is calculated from the expiration of the expected response time. For example, after the requesting device sends a data request to the requested device, the requesting device waits for an expected response time, and after the expected response time expires, sends an inquiry request to the requested device according to the convergence inquiry frequency until the reference response time expires .

Here, the converging query frequency means that the query frequency of the query requests sent by the requesting device to the requested device in each response waiting period is arranged in a convergent order, that is, the closer to the expiration of the response waiting period, the query frequency of the query requests higher.

Preferably, the frequency of the convergence inquiry can be determined according to the N-division method of the remaining time ratio in each response waiting period. Here, N may be determined according to the length of the reference response time, the current load status of the requested device, and the like.

For example, the convergence query frequency can be determined by the 2-point method. The requesting device sends a query request to the requested device at the time points corresponding to 1/2, 3/4, 7/8... of the reference response time, so that during the current response waiting period At the beginning, the inquiry frequency of the inquiry request is low, and when it is closer to the reference response time, gradually increase the inquiry frequency of the inquiry request, so as to avoid the situation that the requested equipment is not working properly and the requesting equipment is idle, and at the same time, the response waiting time can be quickly converged .

Those skilled in the art should be able to understand that although the two-point method is used as an example above, this example should not be construed as any limitation to the present invention, but only for the purpose of illustrating the present invention. Therefore, other N values are also applicable to the present invention, and thus fall within the patent protection scope of the present invention.

Further, during the response waiting period, the query request sent by the requesting device to the requested device may be a pure query request, which is only used to obtain the processing status of the requested device, or the query request may also be the same as the original data request, It is only necessary to add identification information that enables the requested device to distinguish it from the original data request, such as adding an inquiry identification bit "1" or adding request sequence numbers 2, 3, 4, etc., to distinguish it from the original data request without an inquiry identification bit Or the query identification bit is "0", or the request sequence number of the original data request is 1. Accordingly, after the requested device receives the original data request from the requesting device, and subsequently receives the data request from the requesting device, it can judge from the query identification bit or request sequence number of the subsequently received data request that it is used to allow the requested device A data request that requests the device to respond and start the task, or an inquiry request to obtain the processing status of the requested device. After determining the purpose of the request, the requested device gives corresponding feedback, such as whether the task of the data request is started or whether the processing is completed, or Informs the requesting device that it is still processing.

In step S2, the requesting device sends an inquiry request to the requested device at each request time point until a predetermined stop condition is met. Among them, the predetermined stopping conditions include any of the following:

1) The reference response time has expired. When the reference response time expires, the requesting device no longer sends an inquiry request to the requested device according to the convergence inquiry frequency. Preferably, when the reference response time expires but the requesting device has not yet obtained a response from the requested device, the requesting device sends an inquiry request to the requested device at a fixed inquiry frequency, such as sending an inquiry request every 5 seconds.

2) Get the response from the requested device. When the response from the requested device is obtained, the purpose of the data request has been achieved, so the requesting device does not need to inquire about the processing status of the requested device.

Preferably, in step S2, at each request time point, the requesting device not only sends an inquiry request to the requested device, but also provides the user of the requesting device with the remaining waiting time during the current response waiting period. Wherein, the remaining waiting time is the difference between the reference response time and the elapsed waiting time.

Fig. 2 is a schematic diagram of an apparatus according to another embodiment of the present invention, which specifically shows an inquiry apparatus for responding to an inquiry at the requesting device side in an asynchronous interaction. As shown in FIG. 2 , the inquiry device 1 includes a request time determining device 11 and an inquiry request sending device 12 .

Specifically, after the requesting device sends a data request to the requested device, the request time determining means 11 determines that within the current response waiting period The request time point for each query request.

Here, the reference response time corresponding to the requested device means the reference response time for the requesting device to obtain the data response corresponding to the data request from the requested device; each response waiting period means that the requesting device sends The reference response time elapsed after a data request.

Wherein, the reference response time corresponding to the requested device may be determined based on at least any of the following:

1) The response time of the historical response obtained by the requesting device;

Here, the reference response time corresponding to the requested device may be determined based on the response time of historical responses obtained by the requesting device. Wherein, the historical responses obtained by the requesting device include historical responses obtained from the current requested device and historical responses obtained from other requested devices. A reference response time may be determined based on the response times of all or some of these historical responses. For example, the reference response time corresponding to the requested device may be the response time when it responded to the requesting device last time, or the response time when other requested devices responded to the requesting device last time. As another example, the reference response time corresponding to the requested device can be determined based on the response time of historical responses obtained by the requesting device within a period of time, such as the average value, maximum value or minimum value of the responses obtained in the latest time, and these responses can be It is limited to responses from the currently requested device, and may also include responses from other requested devices.

2) the expected response time provided by the requested device;

Here, the reference response time corresponding to the requested device may be determined based on the expected response time provided by the requested device. For example, after receiving the data request from the requesting device, the requested device can return an expected response time to the requesting device according to the type of data request, the current load status of the requested device, etc., and the expected response time can be used as the The corresponding reference response time; or, add or subtract a predetermined length of time on the basis of the expected response time, and use the increased or decreased time as the reference response time corresponding to the requested device.

3) The combination of the response time of historical responses obtained by the requesting device and the expected response time provided by the requested device.

Here, the reference response time corresponding to the requested device may be determined by combining the response time of historical responses obtained by the requesting device and the expected response time provided by the requested device. For example, the reference response time corresponding to the requested device may be set by selecting a longer or shorter time between the response time of the historical response obtained by the requesting device and the expected response time provided by the requested device.

Preferably, when the response time of the historical response obtained by the requesting device is greater than the expected response time provided by the requested device, the reference response time corresponding to the requested device is the difference between the two and is calculated from the expiration of the expected response time. For example, after the requesting device sends a data request to the requested device, the requesting device waits for an expected response time, and after the expected response time expires, sends an inquiry request to the requested device according to the convergence inquiry frequency until the reference response time expires .

Here, the converging query frequency means that the query frequency of the query requests sent by the requesting device to the requested device in each response waiting period is arranged in a convergent order, that is, the closer to the expiration of the response waiting period, the query frequency of the query requests higher.

Preferably, the frequency of the convergence inquiry can be determined according to the N-division method of the remaining time ratio in each response waiting period. Here, N may be determined according to the length of the reference response time, the current load status of the requested device, and the like.

For example, the convergence query frequency can be determined by the 2-point method. The requesting device sends a query request to the requested device at the time points corresponding to 1/2, 3/4, 7/8... of the reference response time, so that during the current response waiting period At the beginning, the inquiry frequency of the inquiry request is low, and when it is closer to the reference response time, gradually increase the inquiry frequency of the inquiry request, so as to avoid the situation that the requested equipment is not working properly and the requesting equipment is idle, and at the same time, the response waiting time can be quickly converged .

Those skilled in the art should be able to understand that although the two-point method is used as an example above, this example should not be construed as any limitation to the present invention, but only for the purpose of illustrating the present invention. Therefore, other N values are also applicable to the present invention, and thus fall within the patent protection scope of the present invention.

Further, during the response waiting period, the query request sent by the requesting device to the requested device may be a pure query request, which is only used to obtain the processing status of the requested device, or the query request may also be the same as the original data request, It is only necessary to add identification information that enables the requested device to distinguish it from the original data request, such as adding an inquiry identification bit "1" or adding request sequence numbers 2, 3, 4, etc., to distinguish it from the original data request without an inquiry identification bit Or the query identification bit is "0", or the request sequence number of the original data request is 1. Accordingly, after the requested device receives the original data request from the requesting device, and subsequently receives the data request from the requesting device, it can judge from the query identification bit or request sequence number of the subsequently received data request that it is used to allow the requested device A data request that requests the device to respond and start the task, or an inquiry request to obtain the processing status of the requested device. After determining the purpose of the request, the requested device gives corresponding feedback, such as whether the task of the data request is started or whether the processing is completed, or Informs the requesting device that it is still processing.

The inquiry request sending unit 12 sends an inquiry request to the requested device at each request time point until a predetermined stop condition is satisfied. Among them, the predetermined stopping conditions include any of the following:

1) The reference response time has expired. When the reference response time expires, the inquiry request sending unit 12 no longer sends an inquiry request to the requested device according to the convergent inquiry frequency. Preferably, the query device 1 may also include a periodic query sending device (not shown). When the reference response time expires but the requesting device has not yet obtained a response from the requested device, the periodic query sending device sends a periodic query to the requested device according to a fixed query frequency. Inquiry request, such as sending an inquiry request every 5 seconds.

2) Get the response from the requested device. When the response from the requested device is obtained, the purpose of the data request has been achieved, so the requesting device does not need to inquire about the processing status of the requested device.
