How to integrate the WeChat authorized login process into the uniapp platform

1. Foreword

Social media has become an inevitable part of modern society. As WeChat is one of the communication applications with the largest market share in Asia, authorized login has become a necessary part. The uniapp platform is an increasingly popular option, so this article will explain how to integrate the WeChat authorized login process into the uniapp platform.

2. WeChat authorized login

WeChat authorized login refers to the process of allowing websites or applications to access user WeChat account information. The authorization page will typically display the requested permissions and the requested application information, and the user will confirm on this page. After successful authorization, the application will receive an authorization code, which the application can use to call the WeChat API to obtain user information.

The three steps involved in WeChat authorized login are:

(1) Send a request and obtain authorization.

(2) Get the code, send the code as a parameter to the API, and obtain the access_token through the code.

(3) Once access_token is obtained, you can directly call WeChat API to obtain user information.

3. Uniapp WeChat authorized login process

The WeChat authorized login process of the uniapp platform is similar to the ordinary WeChat authorized login process. Create a new project using uniapp and integrate the WeChat authorization module. First, we need to install the dependencies required by uni-app:

npm install uni - app - plus

In your project, open the page that requires the authorized login function and add the following code:

uni.login({
provider: 'weixin',
success: function (loginRes) { // 微信登录成功回调
uni.getUserInfo({
provider: 'weixin',
success: function (infoRes) { // 获取微信用户信息成功回调
var userInfo = infoRes.userInfo;
// 将用户信息提交到服务器进行登录
},
fail: function () {
// 获取微信用户信息失败回调
}
});
},
fail: function () {
// 微信登录失败回调
}
});

In the user After successful authorization, we can obtain the user information and submit it to the server for login. This is the basic WeChat authorized login process. It should be noted that each WeChat authorized API call here needs to be registered on the WeChat development platform and corresponds to the authorized domain name or IP address of the application.
