const config = require('./api.js'); // 请求的base URL const getTokenHandle = () => { return uni.getStorageSync('token') // 获取登录用户token } // 请求白名单页面(不需要token请求的页面) const pageWhiteList = ['pages/login/login', 'pages/login/phoneLogin']; // 请求响应拦截处理 const resInterceptHandle = () => { const routes = getCurrentPages(); // 获取当前打开过的页面路由数组 const curRoute = routes[routes.length - 1].route // 获取当前页面路由 const flag = pageWhiteList.includes(curRoute) if (!flag) { console.log(`---[ ${curRoute} ]页面获取数据需要登录---`) uni.navigateTo({ url: '/pages/login/login' }) } return flag } // 请求参数处理 const requestParam = (data, method) => { let str = ''; if (method == 'post') { str = JSON.stringify(data); return str; } else if (method == 'get') { for (let i in data) { str += i + '=' + data[i] + '&'; } str = str.length > 0 ? str.substring(0, str.length - 1) : ''; return encodeURI(str); } }; // 请求封装 const sendRequest = (method = 'GET', url = '', params = {}, ) => { let promise = new Promise(async (resolve, reject) => { let token = await getTokenHandle() const URL = config.baseUcodeURL + url + (method === 'GET' ? params : '') //网络请求 wx.request({ header: { Authorization: token }, url: URL, method, data: method === 'GET' ? {} : params, success: function(res) { // 响应403拦截跳转登录 if (res.statusCode == 200 && res.data.status === 403) { resInterceptHandle() return } // 服务器返回数据 if (res.statusCode == 200) { resolve(res.data); } else { console.log(`============${method} 请求失败:============`); console.error( '接口地址: ', '【 ' + URL + ' 】' ); console.error('请求参数: ', params); console.error('返回结果: ', res); wx.showToast({ title: res.data.emsg, icon: 'none', duration: 3000, mask: true }); reject(res); } }, fail: function(res) { console.log(`============${method} 请求失败:============`); console.error( '接口地址: ', '【 ' + URL + ' 】' ); console.error('请求参数: ', params); console.error('返回结果: ', res); reject(res); } }); }); return promise; } // 封装post请求(url:请求接口; data:请求参数;) const httpPost = async (url, data) => { const params = requestParam(data, 'post'); const res = await sendRequest('POST', url, params) console.log('post请求成功响应:', res) return res }; // 封装get请求(url:请求接口; data:请求参数;) const httpGet = async (url, data) => { let params = data && JSON.stringify(data) != '{}' ? '?' + requestParam(data, 'get') : ''; const res = await sendRequest('GET', url, params) console.log('get请求成功响应', res) return res }; // 自定义请求类型 const http = async (params = { method: 'GET', url: '', data: {} }) => { const res = await sendRequest(params.method, params.url, params.data) console.log(`自定义${params.method}请求成功响应`, res) return res }; module.exports = { Post: httpPost, Get: httpGet, http: http };
二、在 main.js 中 把封装的方法挂载到全局对象上
const {Get,http,Post} = require("./request/index"); Vue.prototype.$http = http Vue.prototype.$get = Get Vue.prototype.$post = Post
三、使用
this.$post('/login/login', data).then(res => {}).catch(err=>{})
