Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In order to enable the server IP address stored on the wireless client side to be updated correspondingly as soon as possible when the IP address of the server side is changed, the application provides an address updating method, and the method can be used for updating the server IP address configured on the wireless client side to a correct new IP address of the server side as soon as possible. Referring to the example of fig. 1, fig. 1 illustrates the principle of the address update method of the present application.
In general, the wireless client 11 may pre-configure the IP address of the server 12 to which it accesses, and the wireless client 11 may access the server 12 directly through the pre-stored IP address of the server 12 without performing domain name resolution access through DNS. For example, for a certain application APP, including the server 12 and the wireless client 11, the wireless client 11 may directly access the server 12 through the pre-stored IP address of the server 12, request the server 12 for the web content of the APP, and the server 12 feeds back the web content or other application function information to the wireless client 11 for display.
However, it may happen that the IP address of the server 12 is changed at a certain time, and at this time, if the wireless client 11 still accesses through the originally pre-stored IP address, an access failure occurs. In this case, referring to fig. 1, the access relay 13 is provided in the embodiment of the present application, and the access relay 13 is a platform that collectively manages the change of the server address, for example, if the IP address of the server S of a certain application is changed from IP1 to IP2, then information similar to "the IP address of the server S is IP 2" may be recorded in the access relay 13. That is, when the IP address of the server is changed, the first IP address information may be stored in the access relay 13, and the access relay 13 may be configured to store the server addresses of a plurality of services, for example, the server address of one application is IP3, and the server address of another application is IP 4.
When the wireless client 11 fails to access the service end 12 through the originally pre-stored IP address, the wireless client 11 may send a service access request to the access relay 13, requesting to access a target service, which is a service corresponding to the wireless client 11, for example, an application. As described above, the access relay 13 serves as a platform for managing address change of the server, and can update and store the latest IP address of each server in time, and when receiving a service access request from the wireless client 11, can correctly obtain the new IP address of the server currently accessed by the wireless client 11 according to the stored server IP address. And, the access relay 13 may forward the service access request to the service end 12, so that the service end 12 processes the request.
In this example, the access mediator 13 may also receive a service access result returned by the service end 12, for example, a certain application page content requested by the wireless client 11. At this time, the access relay 13 not only feeds back the service access result to the wireless client 11, but also feeds back the new IP address of the service stored in the access relay 13 itself to the wireless client 11. For example, the access mediator 13 may feed back the service access result to the wireless client 11 together with the new IP address of the service end. After receiving the new IP address, the wireless client 11 may update its stored server address to the new IP address, thereby completing the address update of the client side. In this way, when the wireless client 11 accesses the server 12 next time, the access is directly performed according to the updated new IP address, and the access can be successful at this time.
In the above process, it can be seen that the wireless client 11 performs the process shown in fig. 2, and correspondingly, the access relay 13 may perform the process shown in fig. 3.
In step 201, when the target service access through the pre-stored server IP address fails, a service access request for the target service is sent to the access mediator.
In step 202, a service access result of the access target service and a new IP address of the server, which are returned by the access relay, are received, and the service access result is obtained by the access relay according to the new IP address of the server.
In step 203, the stored IP address of the server is updated to the new IP address.
In step 301, a service access request for a target service sent by a client is received.
In step 302, according to the new IP address of the server of the target service stored locally, the service access request is forwarded to the server, and the service access result returned by the server is obtained.
In step 303, the service access result and the new IP address of the server are sent to the client, so that the client updates the server IP address stored in advance to the new IP address.
The address updating method can be compatible with the current mode of directly accessing according to the IP address of the server, and under the normal condition, if the IP address of the server is kept unchanged and is always the same as the IP address prestored by the wireless client, the client can directly access the server by using the IP address.
When the IP address of the server is changed, the method does not need to update the APP version carrying the new IP address of the server to the client, but the wireless client retries the access, namely retries the access once, and can send a service access request by using other information related to the target service instead of using the original IP address when the access is retried. And the request can be received by an access transfer device serving as a server address management unified platform, and the access transfer device can feed back the new IP address of the server to the client so that the client can update the server address to the new IP address according to the new IP address. The processes are automatically completed, namely, as long as the client retries to access once, the correct new IP address of the server can be obtained, the address update of the client is completed, and the subsequent access request can be directly accessed according to the new IP address. The method reduces the influence of the address change of the server on the client, and obviously improves the efficiency of the corresponding client side address update when the address of the server is changed.
In addition, the access relay used in the example of the application, as a unified platform for server address management, can easily implement storage of the update address of the server, and when receiving a service access request of the client, can also obtain the latest address of the corresponding server as soon as possible, and further feed the new address back to the client, thereby implementing updating of the address of the client as soon as possible. Compared with the traditional mode which depends on upgrading the client version, the updating efficiency of the client address is obviously improved.
Fig. 4 illustrates an address updating method, which describes a process of updating a client address by applying the address updating method of the present application, and as shown in fig. 4, the process may include:
in step 401, the wireless client accesses the server via IP address D1.
In this step, the IP address D1 of the server, which is stored in advance by the wireless client, is identical to the IP address currently used by the server, so that the client can access the server successfully when accessing the server through D1, and the server can feed back the service access result to the wireless client in step 402.
In step 403, the IP address of the server is changed from D1 to D2.
In step 404, the correspondence of the server with its IP address D2 may be stored at the access translator. For example, the correspondence between the domain name of the server and the IP address D2 of the server may be stored.
In step 405, the wireless client still accesses the server via IP address D1. In this step, since the server IP address stored on the client side has not been updated yet, and is still D1, the client still accesses the server through D1. However, since the server address has changed, the wireless client will be fed back notification of the access failure in step 406.
In step 407, the wireless client will retry once, but this retry access will use the domain name of the server for access. For example, the wireless client sends a service access request carrying a domain name of the service, which may be received by the access relay.
In step 408, the access transfer device finds out the new IP address D2 of the server corresponding to the domain name according to the correspondence stored in step 404.
In step 409, the access relay forwards the service access request to the server according to D2, and may receive the service access result fed back by the server.
In step 410, the access mediator returns the service access result and the new IP address D2 of the service end to the wireless client.
In step 411, the wireless client updates the originally stored server address D1 to D2.
In step 412, the wireless client accesses the server directly according to the new address D2 of the server.
In the address updating method of the example, when the wireless client fails to access the server through the IP address, the correct new IP address of the server can be obtained by retrying once, and the subsequent access can be performed normally.
