Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0037] Figure 1 FIG. 1 is a schematic diagram of the main process of a login management method according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0038] Step S101: receiving a request for obtaining a login page sent by a client, wherein the request includes a parameter identifier, and the parameter identifier includes a service identifier and a user role identifier;

[0039] Step S102: Acquire login configuration information corresponding to the parameter identifier;

[0040] Step S103: determining a login page corresponding to the acquisition request according to the login configuration information, so as to display the login page on the client.

[0041] In the embodiment of the present invention, the user sends a request to obtain a login page through the client. The login page is a page for logging into the end system. The corresponding end system can be logged in through the obtained login page, wherein the end system indicates the business and role. For example, the end system is a user end system of a B2C (business-to-consumer e-commerce form) business, indicating the B2C business and the role of the user end. The business identifier is the identifier of the business, such as the business can be a B2B (Business-to-Business, which refers to the business model of exchanging and transmitting data information and conducting transaction activities between enterprises through a dedicated network or the Internet) business, a B2C business, etc., or a more subdivided business; the user role identifier is the identifier of the user role or identity, and the user role corresponds to the user end, the management end or the operation end. The parameter identifier includes the business identifier and the business identifier, that is, the parameter identifier indicates the business and the user role, so that the end system to be logged in by the user can be determined according to the parameter identifier, that is, the login page of the end system is determined, and different end systems correspond to different businesses and user roles. For example, the user end system of the B2C business, the B2C business management end system and the B2C business operation end system are different end systems.

[0042] In the embodiment of the present invention, the parameter identifier can be assembled according to the business identifier and the user role identifier in a preset format, and the preset format can be customized. For example, if the business identifier is B2C, the role identifier is C, and the parameter identifier is b2c_c.

[0043] In the embodiment of the present invention, the request for obtaining the login page sent by the client may be sent by inputting a URL.

[0044] In an embodiment of the present invention, the request for obtaining the login page sent by the client may also be generated by the user clicking a business button corresponding to the business identifier and a role button corresponding to the role identifier, respectively. Specifically, the client assembles a parameter identifier in a preset format based on the business identifier corresponding to the business button clicked by the user and the role corresponding to the role identifier, and then generates a request for obtaining the login page corresponding to the parameter identifier based on the parameter identifier and the request generation rule.

[0045] In the embodiment of the present invention, after receiving the acquisition request of the login page sent by the client, the method may include: verifying the acquisition request, and if the verification passes, obtaining the login configuration information corresponding to the parameter identifier. If the verification fails, returning error information to the client.

[0046] In an embodiment of the present invention, the acquisition request is verified, and the format of the parameter identifier in the acquisition request can be verified. For example, when a user sends an acquisition request for a login page by entering a URL, there may be a situation where the parameter identifier format is incorrect, resulting in a verification failure. When the verification fails, a prompt message indicating the parameter error can be returned to the client.

[0047] In an embodiment of the present invention, before obtaining the login configuration information corresponding to the parameter identifier, the method includes: configuring the login configuration information corresponding to the parameter identifier. That is, the login configuration information corresponding to each parameter identifier is preconfigured, and then each parameter identifier and the corresponding login configuration information are stored in a database or cache. According to the login configuration information, the login page corresponding to the acquisition request can be determined so that the client can display it.

[0048] In the embodiment of the present invention, Figure 2 As shown, determining the login page corresponding to the acquisition request according to the login configuration information includes:

[0049] Step S201: loading a login component corresponding to the parameter identifier according to the login configuration information;

[0052] In an embodiment of the present invention, the login configuration information includes the relative path address, the request domain name address and the image address of the login component corresponding to the login page. Among them, the relative path address of the login component is the storage location of the login component file, and the login component can be obtained through the relative path of the login component to load the login page according to the login component. The request domain name address is the address of the server of the end system corresponding to the parameter identifier. When the login page monitors the user clicking the login button, a login request is sent to the server of the end system according to the request domain name address. The image address of the login page is the address of the image displayed in the login page. According to the image address, the corresponding image can be loaded. The image can include a logo (trademark) image indicating the end system, and can also include a banner (banner advertisement) image. The image address configuration is used in the login configuration information, and the image in the login page can be changed by modifying the image address in the login configuration information according to business needs in the future, which is more flexible.

[0053] The embodiment of the present invention configures the login components and request domain name addresses and image addresses of each end system in the login configuration information by configuration, which can flexibly respond to modifications of login components, images, etc. by any end system. The login configuration information is easy to maintain and can meet the diverse needs of different end systems for login pages.

[0054] In an embodiment of the present invention, the login configuration information also includes the user service agreement document address and the user privacy agreement document address of the login page. That is, the user service agreement document of the login page can be loaded through the user service agreement document address, and the user privacy agreement document of the login page can be obtained through the user privacy agreement document address. That is, the user can click on the link of the user service agreement or the user privacy agreement on the login page, and the corresponding link is the user service agreement document address or the user privacy agreement document address, and then obtain the user service agreement document or the user privacy agreement document for viewing.

[0055] In the embodiment of the present invention, the login configuration information may be a JSON data structure. JSON is a lightweight data exchange format with the characteristics of simple data format, easy to read and write, small bandwidth occupation, and easy to parse. The login configuration information adopts a JSON data structure, which can improve the loading efficiency of the login component, thereby improving the display efficiency of the login page and improving the user experience.

[0056] In the embodiment of the present invention, the login configuration information may also be other data structures, such as a YAML data structure, which is intuitive and easy to identify.

[0057] In the embodiment of the present invention, the parameter identifier also includes a region identifier. The region identifier is used to identify the region corresponding to the business line. For example, if the business line is a B2C business, the region corresponding to the B2C business may be the business area of ​​the business. The business area may be one or more cities, and the region identifier may be the identifier of the city. By setting the region identifier in the parameter identifier, private domain management of the business line can be achieved.
