Referring to FIG. 2, the first embodiment of a method for accessing a web page of the present invention, the method for accessing a web page includes:

In step S10, each IP to be tested is acquired when it is detected that the access to the network page is abnormal.

Step S20, sending a probe request to each of the IPs to be tested.

When a user browses a web page, once the public network link problem, cross-network access, network policy setting and server configuration change occur, the IP address of the server node accessed by the user will be unreachable or the application error will occur, and the page cannot be accessed. The terminal involved in the method for accessing a web page provided by the present invention is a mobile terminal such as a computer and a smart phone, and a related application system, including but not limited to an APP or a web page system, is preloaded on the mobile terminal. A software development kit (Software Development Kit, SDK for short) is implanted in the application system. An IP list consisting of multiple server IPs is preset in the software development kit.

For example, the schematic diagram of the IP list shown in FIG. 3 . The IPs in the IP list are divided into multiple groups, and two or more IPs in each group are IPs that match each other.

When the user opens the application system and browses the web page, the mobile terminal obtains the access status of the web page. When an abnormal web page access is detected, the software development kit calls each IP to be tested, and sends a probe request to each IP to be tested at the same time.

Wherein, the IP to be tested is an IP in a preset IP list. The IP to be tested can include all IPs in the IP list, or part of the IPs in the IP list.

In addition, because each group of IPs in the IP list matches each other, if one IP in the same group is abnormally unavailable, other IPs in the same group are also unavailable. At the same time, in order to detect available IPs, ensure that the number of IPs to be tested is sufficient. Therefore, the method for obtaining the IP to be tested may be to select one IP from each group of IPs in the preset IP list as the IP to be tested for detection, so as to provide the available IP to the maximum extent and reduce the need for detection. Measure the number of IPs to improve detection efficiency.

Step S30, receiving the feedback result of the IP to be tested, and determining the target IP of the IP to be tested that is in a normal state in the feedback result;

Step S40, switching the access entry of the current web page to the target IP.

After the mobile terminal sends a detection request with a preset code to the server of each IP to be tested, the server feeds back the result to the mobile terminal according to the detection request, and the feedback result includes a round-trip time (RTT) and a status code. Status codes include codes for normal states and abnormal states. When the status code of the feedback result is normal, it indicates that the server is available, and the IP to be tested that feeds back the feedback result is used as the target IP. Then, the access entry of the current network page is switched to the target IP. Through the software development kit embedded in the application system, the target IP in the normal state of the IP to be tested is detected, and the target IP is used as the access entry of the current network page, and the current user's service request will be completed through the target IP. No need to wait for DNS caching. When the network page access fails, the IP address can be quickly switched to ensure that the user can access the page in time.

In this embodiment, when an abnormality in accessing a web page is detected, the software development toolkit retrieves each IP to be tested, and simultaneously sends a detection request to each IP to be tested. After the mobile terminal sends the detection request of the preset code to the server of each IP to be tested, the server feeds back the result to the mobile terminal according to the detection request. When the feedback result is in a normal state, it indicates that the server is available, and the IP to be tested that feeds back the feedback result is used as the target IP. Then, the access entry of the current network page is switched to the target IP. Through the software development kit embedded in the application system, the target IP in the normal state of the IP to be tested is detected, and the target IP is used as the access entry of the current network page, and the current user's service request will be completed through the target IP. No need to wait for DNS caching. When the network page access fails, the IP address can be quickly switched to ensure that the user can access the page in time.

Referring to FIG. 4 , the second embodiment of the method for accessing a web page of the present invention, based on the first embodiment described above, the step S30 includes:

Step S31, receiving the feedback result of the IP to be tested.

Step S32, judging whether there are multiple feedback results that are in a normal state.

Step S33, when there are multiple feedback results that are in a normal state, obtain the round-trip time of the probe request in the feedback results of the normal state.

Step S34, taking the IP with the smallest round-trip time as the target IP.

Step S35, when only one of the feedback results is in a normal state, the IP to be tested whose feedback result is in a normal state is used as the target IP.

After receiving the feedback result of the IP to be tested based on the probe request, obtain the round-trip time and status code in the feedback result. The status code is divided into normal state and abnormal state, and there may be multiple IPs to be tested in normal state. Therefore, when determining the target IP, it is first determined whether there are multiple IPs to be tested whose feedback results are in the normal state, and when there are multiple feedback results that are in the normal state, the round-trip time in the feedback results in the normal state is obtained. The shorter the round-trip time, the higher the ability of the server of the IP to be tested to process service requests. The IP to be tested with the smallest round-trip time is used as the target IP to improve the response speed of the web page. When only one feedback result is in a normal state, the IP to be tested in the normal state is directly used as the target IP.

In addition, if the status codes in all the feedback results are abnormal and there is no normal IP to be tested, the control application system will continue to wait for the DNS cache. Obtain an available IP from the Internet, and use this IP to access the web page to ensure that the web page can be accessed successfully. Further, when there is no feedback result of normal state, a prompt message can be generated to remind the user that there is no available IP in the current application system, and the user is requested to wait patiently for the domain name system to cache, so as to avoid the page being abnormal for a long time, the user is unknown, and the user leaves the page.

Further, a round-trip time correction value is preset for each IP to be tested, and after the mobile terminal obtains the round-trip time fed back by each IP to be tested whose status code is in a normal state, the round-trip time of the IP to be tested is calculated using the respective round-trip time correction value. Make corrections. Take the IP with the smallest modified round-trip time as the destination IP. The round-trip time correction operation may be adding the real round-trip time of the IP to be tested plus the round-trip time correction value, or multiplying the real round-trip time by the round-trip time correction value as the corrected round-trip time, or other correction methods. , which is not limited here.

For example, when the correction method is the real round-trip time plus the round-trip time correction value, it is detected that the status codes of the three IP addresses to be tested are all normal, and the three IP addresses to be tested are ID1, ID2 and ID3, among which, ID1 The preset round-trip time correction value is 0ms, the preset round-trip time correction value of ID2 is 200ms, and the preset round-trip time correction value of ID3 is 100ms. The obtained real round-trip time of ID1 is 200ms, the real round-trip time of ID2 is 100ms, and the real round-trip time of ID3 is 200ms. Then the round-trip time of ID1 after correction is 200ms, the round-trip time of ID2 is 300ms, and the round-trip time of ID3 is 300ms, that is, ID1 is taken as the target IP.

The round-trip time correction value of each IP address to be tested can be determined according to the operating cost of the IDC room corresponding to each IP address to be tested and the RTT distribution of each IP address; for example, it can be set to the higher the operating cost of the IDC room corresponding to the IP address, the The larger the corresponding round-trip delay correction value is, or the smaller the real round-trip delay of the IP address is, the larger the corresponding round-trip delay correction value will be. It can also be set based on the operating cost of the IDC room and the RTT distribution of each IP address. Through the correction of the IP address correction value, the number of terminals accessed by each IP address corresponding to the application program is balanced.

In this embodiment, after receiving the feedback result of the IP to be tested based on the probe request feedback, the round-trip time and status code in the feedback result are obtained. The status code is divided into a normal state and an abnormal state, and there may be multiple normal states. IP to be tested. Therefore, when determining the target IP, it is first determined whether there are multiple IPs to be tested whose feedback results are in the normal state, and when there are multiple feedback results that are in the normal state, the round-trip time in the feedback results in the normal state is obtained. The shorter the round-trip time, the higher the ability of the server of the IP to be tested to process service requests. The IP to be tested with the smallest round-trip time is used as the target IP to improve the response speed of the web page. When only one feedback result is in a normal state, the IP to be tested in the normal state is directly used as the target IP. The network page only needs one access interface at the same time, so there is only one target IP. The technical solution in this embodiment can effectively prevent the program from being unable to select the target IP when there are multiple feedback results of the normal state, resulting in the network page being unable to be timely. The phenomenon of successful access occurs, providing users with a good page access environment.

In addition, an embodiment of the present invention also provides a device for accessing a network page, where the device for accessing a network page includes: a memory, a processor, and access to a network page stored in the memory and running on the processor The program, when the program for accessing the network page is executed by the processor, implements the steps of the method for accessing the network page described in the above embodiments.
