How to log in to the backend of multiple mini programs in uniapp uniformly

In recent years, with the continuous growth of the WeChat ecosystem, mini programs have become an extremely popular form of mobile applications. In the development process of small programs, uniapp has become a popular cross-platform development framework. However, when we need to develop multiple sets of background services for different mini-programs, how to achieve unified user login and data synchronization becomes very critical.

This article will introduce how to use uniapp to develop multiple small program backends, and achieve unified user login and data synchronization, making the development process more convenient.

1. uniapp develops multiple sets of small program backends

To implement uniapp to develop multiple sets of small program backends, we need to develop according to the following steps:

1. Create multiple sets of backends Mini Program Application

First, create multiple mini program applications on the WeChat public platform and bind them in their respective mini program applications. In this way, multiple small program applications can be run simultaneously on the same server.

2. Create multiple background services

According to different mini program application requirements, we need to create multiple background services on the same server. These services need to provide different interfaces and data to meet their respective needs.

3. Server configuration

During the uniapp development process, a specific configuration method is required to specify different server addresses for different mini-program applications. We need to modify the server address in different mini program application codes accordingly to provide services for each mini program service separately.

4. Code implementation

We need to write the corresponding background service code according to the different application requirements of each applet, and call the corresponding code in each applet Interface to access background data.

2. Unified login and data synchronization

When we develop multiple mini program backends, how do we enable users to achieve unified login and data synchronization in different mini programs? The following is the implementation method:

1. Unified login

We can add a public verification token process to the login process of each mini program. When a user logs in to a mini program, the server returns a token value, which can be shared between different mini programs. In this way, in other mini programs, users can directly use this token for login verification, thereby achieving unified login.

2. Data synchronization

For scenarios where data needs to be accessed across applets or across backends, we need to store the user's data in a unified place, while all applets The program background gets data from this place. This method can realize data sharing between different applets.

For sharing small amounts of data, you can use WeChat’s own data storage service “Cloud Development”. In mini programs, data can be stored and obtained through cloud development APIs to achieve data sharing;

For sharing of large amounts of data, middleware technology can be used on the server side to merge data from different backgrounds.

3. Summary

When uniapp develops multiple sets of mini program backends, we need to create multiple backend services according to different mini program application requirements, and specify different mini program applications. server address. At the same time, we can achieve unified login and data synchronization, allowing users to enjoy a unified user experience across different mini programs.

In the actual development process, we also need to pay attention to the needs of different small programs and continuously optimize the quality and performance of background services. We believe that through this method, your development work of multiple mini program background services will be more efficient and convenient.
