[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The service update method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the client 102 communicates with the back-end server 104 through the network, and the management server 106 can communicate with both the client 102 and the back-end server 104. Among them, the client 102 can be, but is not limited to, running on various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The back-end server 104 and the management server 106 can be implemented using independent servers or server clusters consisting of multiple servers.

[0027] The present application embodiment provides a service update method, which is applied to Figure 1 The client 102 shown in FIG. Figure 2 , the method includes steps S202 to S204.

[0028] S202: In response to a first switching instruction, the access object of the backend service request is switched from the first official service to the first grayscale service.

[0029] The first switching instruction is issued by the management server when the first grayscale service test passes. The first official service is the official backend service of the current version, and the first grayscale service is the grayscale backend service of the updated version. It can be understood that the request to access the backend service is a request issued by the client when it needs to use the service provided by the backend. The backend server generally encapsulates different backend services into corresponding interfaces. The client can select the required backend service to access according to the interface document and interface number. The client switches the access object of the backend service request to access the backend service by modifying the request header of the backend service request. Before the updated version of the backend service is launched, all client requests to access the backend service will be processed by the first official service. The updated version of the backend service needs to undergo grayscale testing to determine whether it can provide stable services. Therefore, the first grayscale service will be launched first, and the tester will test the first grayscale service. If there is a problem, the first grayscale service will be repaired until the first grayscale service passes the test. The first grayscale service passing the test indicates that it can provide stable services. At this time, the management server sends a first switching instruction to the client to instruct the client to transfer all traffic directed to the backend from the first official service to the first grayscale service, and the first grayscale service temporarily handles the client's request.

[0030] S204: In response to the second switching instruction, the access object of the backend service request is switched from the first grayscale service to the second official service.

[0031] The second switching instruction is issued by the management server when the first formal service version is updated to the second formal service, and the second formal service is the formal backend service of the updated version. It can be understood that after all the traffic of the client is transferred to the first grayscale service, the deployment unit of the first formal service will have no traffic access, and the management server can start to update the version of the first formal service. Based on the first grayscale service that has passed the test, the second formal service can be obtained. Based on the second formal service, the version is updated on the deployment unit of the first formal service. The specific method of version update can be: directly using the second formal service to replace the first formal service on the deployment unit of the first formal service, or the first formal service can be differentially updated according to the second formal service. Since the deployment unit of the grayscale backend service is temporarily used for grayscale testing, after completing the update on the deployment unit used to deploy the formal backend service, the client's traffic needs to be transferred back to access the formal backend service. Therefore, after determining that the first formal service version is updated to the second formal service, the management server sends a second switching instruction to the client to instruct the client to transfer all traffic directed to the backend from the first grayscale service back to the second formal service, and the second formal service stably handles the client's request.

[0032] Based on the service update method in this embodiment, during the backend service version update process, the on-line and off-line of the backend service are managed by the management server. Under the instruction of the management server, the client first temporarily transfers the traffic to the first grayscale service that has passed the grayscale test, and when the first formal service is updated to the second formal service, it switches the traffic back to the second formal service. This method ensures that there is no scenario where the old version of the backend service is offline for no reason, causing the client to be unable to connect to any backend service, and the client will always have a backend service that it can connect to. At the same time, it also solves the problem that the client's token becomes invalid when the client is disconnected from the backend service for a long time, causing the client to exit without reason.

[0033] In one embodiment, the entire system can be a structure with front-end and back-end separation, such as Figure 3As shown, the front-end proxy server is connected to the client for communication, and the back-end proxy server is connected to the front-end proxy server and the back-end server for communication, respectively. The front-end proxy server is used to store static resources for building the front-end page, and is also used to forward the client's access to the back-end service request to the back-end proxy server. The back-end proxy server is used to select the access object for service access according to the access to the back-end service request. Since the client and the back-end server are under different domain names, reverse proxy can be performed through the back-end proxy server to achieve cross-domain access. The back-end proxy server can also be used for load balancing of service access. In a specific embodiment, the front-end proxy server can be an nginx server, and the back-end proxy server can expose each back-end service to the front-end proxy server through the ingress-nginx method.

[0034] In one embodiment, before responding to the first switching instruction, the method further includes:

[0035] 1) Read the first static resource, and display the first front-end page according to the first static resource. The first front-end page is the front-end page of the current version.

[0036] 2) Generate a backend service access request for accessing the first official service according to the operation received by the first front-end page.

[0037] It is understandable that if applied to Figure 3 In the architecture, the first static resource, such as HTML, CSS, JS, etc., can be read from the front-end proxy server, and the client can parse and render the first static resource to build the first front-end page. Before the updated version appears, ordinary users perform operations on the first front-end page. These operations can be classified into front-end operations and back-end operations. Specifically, the front-end operation can be performed normally without the back-end server providing data, such as sliding, scrolling and reading on the front-end page, and entering content in the input control of the front-end page. The data entered by the front-end operation can be cached in the front-end proxy server as static data. When the client is closed or refreshed, these cached static data can be read back from the front-end proxy server to prevent the loss of data previously entered by ordinary users. Back-end operations are operations that require data support returned by the back-end server, such as database queries, and application software deployed by SaaS service providers on their own services. When the user's operation is a back-end operation, an access back-end service request for accessing the first formal service will be generated to request the data required for the back-end operation from the back-end server.

[0038] In one embodiment, when an updated version of a service is released, if a matching front-end page is released together, the front-end page should also be updated on the front-end. Specifically, in response to the first switching instruction, the access object of the back-end service request is switched from the first official service to the first grayscale service, and further includes:

[0039] 1) In response to a first switching instruction, determining whether an operation performed in a first front page is a refreshable operation.

[0040] It can be understood that the refreshable operation here refers to the operation of refreshing the front-end page without losing data. In the architecture with front-end and back-end separation, the back-end operation generates the corresponding access back-end service request based on the content that the user has entered on the front-end. Since the input has been completed, page refresh will not have any effect. Therefore, the refreshable operation includes the back-end operation. The front-end operation can be divided into input operation and non-input operation based on whether the content is input. When the input operation is in progress, refreshing the front-end page may cause the loss of part of the input because the input has not been completed. Non-input operations, such as sliding pages, zooming pages, etc., are not related to data, so there will be no data loss problem. Therefore, the refreshable operation can also include non-input operations in the front-end operation.

[0041] 2) If not, the first front-end page is displayed until the operation performed is a refreshable operation, in which case the page is refreshed and the second static resource is read, and the second front-end page is displayed according to the second static resource.

[0042] The second front-end page is an updated version of the front-end page. It is understandable that the version update of the front-end page requires page refresh on the front end, and reads new static resources when refreshing to rebuild the front-end page. However, if the operation being performed on the front end is not a refreshable operation, refreshing the page will result in data loss, such as the loss of content that the user has not completed entering as mentioned above, and a senseless version update cannot be achieved. Therefore, when faced with this situation, do not refresh the page first, keep displaying the first front-end page, wait for the user to complete the non-refreshable operation on the first front-end page, and switch to a refreshable operation. At this time, by sending a first resource acquisition request to the front-end proxy server to read the second static resource from the front-end proxy server, and construct a second front-end page based on the second static resource, and then after the refresh is completed, display the second front-end page on the front end to achieve a senseless version update of the front end.

[0043] 3) If yes, directly refresh the page and read the second static resource, and display the second front-end page according to the second static resource.

[0044] If the front-end is performing a refreshable operation, refreshing the page will not have a negative impact on the user. Therefore, the page can be refreshed directly. During the refresh process, a second resource acquisition request is sent to the front-end proxy server to read the second static resource from the front-end proxy server, and a second front-end page is constructed based on the second static resource. After the refresh is completed, the second front-end page is displayed on the front-end to achieve a seamless version update of the front-end.

[0045] The above embodiment is for ordinary users to update the version without feeling during the use of the service, but the tester also needs to use the client to perform grayscale testing on the first grayscale service. Specifically, in one embodiment, if the user of the client is a tester, before responding to the first switching instruction, it also includes:

[0046] 1) Read the grayscale static resources and display the third front-end page based on the grayscale static resources.

[0047] The third front-end page is an updated version of the grayscale front-end page. It is understandable that identity information can be set on the login account used to log in to the client, and the client can distinguish between testers and ordinary users through identity information. For testers, the front-end and back-end can be tested together during the grayscale test, so an updated version of the grayscale front-end page, that is, the third front-end page, should be shown to them to test the third front-end page. During the test process, if there is a problem with the third front-end page, it can be modified in time, and finally the second front-end page can be obtained based on the third front-end page that has passed the test.

[0048] 2) Generate a backend service access request for accessing the first grayscale service based on the operation received by the third front-end page.

[0049] It can be understood that at this time, ordinary users will access the first official service, and this embodiment will divert the access traffic of the tester and guide the access traffic of the tester to the first grayscale service, so that the tester can test the first grayscale service. During the test process, if there is a problem with the first grayscale service, it can be modified in time, and finally the second official service can be obtained based on the first grayscale service that has passed the test.

[0050] The service update method provided in the embodiment of the present application can be applied to Figure 1 106 in the management server, see Figure 4 , the method includes steps S402 to S408.

[0051] S402, while the first official service is online, the first grayscale service is launched.

[0052] The first official service is the official backend service of the current version, and the first grayscale service is the grayscale backend service of the updated version. It is understandable that before the updated version of the backend service is officially released, grayscale testing is required. During the grayscale testing process, the first official service and the first grayscale service will exist at the same time. Based on the user's identity, the client sets the access object of the ordinary user's access to the backend service to the first official service, and the access object of the tester's access to the backend service to the first grayscale service. In this way, during the grayscale testing process, ordinary users still have backend services available, and testers can also perform grayscale testing on the updated version of the backend service at the same time.

[0053] S404: When the test of the first grayscale service passes, send a first switching instruction to the client.

[0054] The first switching instruction is used to instruct the client to switch the access object of the backend service request from the first official service to the first grayscale service. When it is determined that the test of the first grayscale service has passed, the first grayscale service can be used to temporarily provide an updated version of the backend service for ordinary users. By sending the first switching instruction to the client, the client switches the access object of the backend service request of ordinary users from the first official service to the first grayscale service.

[0055] S406: Update the version of the first official service.

[0056] After directing the access traffic of ordinary users to the first grayscale service, the first official service can be updated. Based on the first grayscale service that has passed the test, the second official service can be obtained. Based on the second official service, the version is updated on the deployment unit of the first official service. The specific method of version update can be: directly using the second official service to replace the first official service on the deployment unit of the first official service, or performing a differential update on the first official service based on the second official service.

[0057] S408: When the first official service version is updated to the second official service, a second switching instruction is sent to the client.

[0058] The second official service is an updated version of the official backend service, and the second switching instruction is used to instruct the client to switch the access object of the backend service request from the first grayscale service to the second official service. It can be understood that since the deployment unit of the grayscale backend service is temporarily used for grayscale testing, after the update is completed on the deployment unit used to deploy the official backend service, the client's traffic needs to be transferred back to access the official backend service. Therefore, after determining that the first official service version is updated to the second official service, the management server sends a second switching instruction to the client to instruct the client to transfer all traffic directed to the backend from the first grayscale service back to the second official service, and the second official service will stably process the client's requests.

[0059] From the perspective of multi-terminal interaction, see Figure 5 , the service update method includes steps S502 to S512.

[0060] S502, when the first official service is online, the management server launches the first grayscale service.

[0061] The first official service is the official backend service of the current version, and the first grayscale service is the grayscale backend service of the updated version.

[0062] S504: When the test of the first grayscale service passes, the management server sends a first switching instruction to the client.

[0063] S506: In response to the first switching instruction, the client switches the access object of the backend service request from the first official service to the first grayscale service.

[0064] S508: The management server updates the version of the first official service.

[0065] S510: When the first official service is updated to the second official service, the management server sends a second switching instruction to the client.

[0066] The second official service is an updated version of the official backend service.

[0067] S512: In response to the second switching instruction, the client switches the access object of the backend service request from the first grayscale service to the second official service.

[0068] For the description of steps S502 to S512 , please refer to the above.

[0069] An embodiment of the present application provides a service update device, which is applied to a client, and the device includes a first response module and a second response module. The first response module is used to switch the access object of the backend service request from the first formal service to the first grayscale service in response to a first switching instruction. The first switching instruction is issued by the management server when the first grayscale service test passes, the first formal service is the formal backend service of the current version, and the first grayscale service is the grayscale backend service of the updated version. The second response module is used to switch the access object of the backend service request from the first grayscale service to the second formal service in response to the second switching instruction. The second switching instruction is issued by the management server when the first formal service version is updated to the second formal service, and the second formal service is the formal backend service of the updated version.

[0070] In one embodiment, the first response module further includes a display unit. The display unit is used to read the first static resource and display the first front-end page according to the first static resource. The first front-end page is the front-end page of the current version. According to the operation received by the first front-end page, an access back-end service request for accessing the first formal service is generated.

[0071] In one implementation, the display unit is further used to respond to the first switching instruction and determine whether the operation performed in the first front-end page is a refreshable operation. If not, the first front-end page is displayed until the operation performed is a refreshable operation, the page is refreshed and the second static resource is read, and the second front-end page is displayed according to the second static resource. The second front-end page is an updated version of the front-end page.
