uview2.0 encapsula las solicitudes de red (el último método de inicio de sesión del subprograma WeChat)

1. Solicitud de red e interceptor correspondiente

// 此vm参数为页面的实例，可以通过它引用vuex中的变量
module.exports = (vm) => {
    // 初始化请求配置
    uni.$u.http.setConfig((config) => {
        config.baseURL = 'http://127.0.0.1:8080/';
        return config
    })
	
	// 请求拦截
	uni.$u.http.interceptors.request.use((config) => { 
		//根据custom参数中配置的是否需要token，添加对应的请求头
		if(config?.custom?.auth) {
			config.header.token = uni.getStorageSync("token")
		}
	    return config 
	}, config => { // 可使用async await 做异步操作
	    return Promise.reject(config)
	})
	
	
	uni.$u.http.interceptors.response.use((response) => {
		/* 对响应成功做点什么 可使用async await 做异步操作*/
		if (response.data.code !== 200) { // 服务端返回的状态码不等于200，则reject()
		   	return Promise.reject(response)
		}	 // return Promise.reject 可使promise状态进入catch
		if (response.config.custom.verification) { // 演示自定义参数的作用
		  	return response.data
		}
		return response
	}, (response) => {
		/*  对响应错误做点什么 （statusCode !== 200）*/
		console.log(response)
		return Promise.reject(response)
	})
}

2. El archivo main.js introduce el interceptor
Nota:
Coloque esta parte entre new Vue() y app.$mount(), para que pueda usarse normalmente en App.vue

// 引入请求封装，将app参数传递到配置中
require('./common/http.interceptor.js')(app)

3. Cree un archivo de administración centralizada de API

const http = uni.$u.http
// 登录接口(获取code) post请求
export const getLoginCode = (data) => http.post('wx/code/' + data)
//登录接口(用户登录) post请求
export const realyLoginInfo = (params, config = {}) => http.post('wx/login', params,config)

4. La página de inicio de sesión hace referencia a la API y la usa

import {getLoginCode,realyLoginInfo} from '@/common/http.api.js'

5. Ejemplo de código completo de la página de inicio de sesión
