mpvue 小程序 使用wx.request请求数据
1.创建src下创建utils/wx-request.js
const host = 'http://10.0.0.6:8081' function request (url, method, data, header = {}) { wx.showLoading({ title: '加载中' // 数据请求前loading }) return new Promise((resolve, reject) => { wx.request({ url: host + url, // 仅为示例,并非真实的接口地址 method: method, data: data, headers: { 'content-type': 'application/json' // 默认值 }, success: function (res) { wx.hideLoading() resolve(res.data) }, fail: function (res) { wx.hideLoading() // reject(false) }, complete: function () { wx.hideLoading() } }) }) } function get (obj) { return request(obj.url, 'GET', obj.data) } function post (obj) { return request(obj.url, 'POST', obj.data) } export default { request, get, post, host }
2.main.js中引入到原型
import Vue from 'vue' import App from './App' import WXrequest from './utils/wx-request' Vue.prototype.$httpWX = WXrequest
3.使用
this.$httpWX.post({ url: '/data.json', data: { } }).then(res => { console.log(res) })
