1.新建一个request.js文件
var app = getApp(); const baseUrl = '请求头地址'; // 调接口方法 const fetchData = (url,
data, method, callback, errCallback) => { wx.showLoading(); let token =
wx.getStorageSync('$$token') wx.request({ url: baseUrl + url, header: {
'Authorization': token, }, method: method, data: data, success: function (res)
{ wx.hideLoading(); // token过期，跳到授权页面 if (res.data.code === 401) {
wx.reLaunch({ url: '/pages/login/login' }) console.log('超时登录，tocken失效') return;
} if (res.data.code !== 200) { if (errCallback) { return errCallback(res); }
wx.showToast({ title: res.data.msg, icon: 'none' }); return; } callback(res); }
}) } // 排除方法，在外面可调用 module.exports = { fetchData: fetchData }
2. 页面引入并调用，按照request里面定义的顺序传参即可
import {fetchData} from '../../utils/request' fetchData('/api/knowledges', {
pageNo: this.data.page, pageSize: this.data.pageSize },'GET', res => {
console.log(res) // 成功结果回调 }, err => { })
