1.新建http云函数,选中http云函数,右键,打开终端,安装依赖:
npm install request-promise
2.http.js引入request-promise用于做网络请求
var rp = require(‘request-promise’);
3.云函数入口函数逻辑
// 云函数入口函数exports.main = async (event, context) => {console.log(event,context)let url = event.url;if (event.method == "post" || event.method == "POST" || event.method == "Post") {//发送post请求} else {//发送get请求}}
4.http.js中get请求
var options = {uri: url,method:"GET",qs: event.datas,headers: {'User-Agent': 'Request-Promise'},json: true };rp(options).then(function (res) {return res}).catch(function (err) {return '失败'});
5.http.js中post请求
var options = {method: 'POST',uri: url,body: {some: 'payload'},form: event.datas,json: true };rp(options).then(function (res) {return res}).catch(function (err) {return '失败'});
6.选中http云函数,右键,上传并部署:云端安装依赖
7.云端测试
8.调用:
wx.cloud.callFunction({// 要调用的云函数名称name: 'http',// 传递给云函数的event参数data: {url:"http://api.xxx.com/api/xxx",method:"get",datas:{msg:"xxx"}}
}).then(res => {console.log(res)
}).catch(err => {console.log(err)
})
