微信小程序post请求

一、普通请求

wx.request({url: 'http://43.143.124.247:8282/sendEmail',method: 'POST',data: {user: that.data.currarr[0][that.data.mulu[0]] + that.data.currarr[1][that.data.mulu[1]] + that.data.sushe,pwd: '3101435196@qq.com'},header: {'Content-Type': 'application/x-www-form-urlencoded', // 设置请求头 Content-Type},success: res => {console.log(res);},fail: err => {console.log(err);}})

二、云开发请求

调用端

wx.cloud.callFunction({name: 'request_spider',data: {code: 'sendEmail',url: 'http://43.143.124.247:8282/sendEmail',data: {user: that.data.currarr[0][that.data.mulu[0]] + that.data.currarr[1][that.data.mulu[1]] + that.data.sushe,pwd: '3101435196@qq.com'}}}).then(res => {console.log('update-->res', res)}).catch(err => {console.log('update-->err', err)})

被调用端

// 云函数入口文件
const cloud = require('wx-server-sdk')cloud.init({env: cloud.DYNAMIC_CURRENT_ENV
}) // 使用当前云环境// var request = require('request-promise');
const rp = require('request-promise-native');
const querystring = require('querystring');
const axios = require('axios')exports.main = async (event, context) => {// 根据发起请求携带的不同参数进行不同的操作const code = event.codeconsole.log("event---------------->", event)if (code == 'sendEmail') {// 进行登录操作return sendEmail(event.url, event.data);}
};// 登录函数
async function sendEmail(url, data) {const formBody = querystring.stringify(data);try {const options = {method: 'POST',uri: url,body: formBody,// json: false, // 自动将请求体转为JSONheaders: {'Content-Type': 'application/x-www-form-urlencoded','Content-Length': Buffer.byteLength(formBody) // 设置内容长度}};const response = await rp(options);return response;} catch (error) {console.error(error);return error;}
}
