主要使用superagent.

发送Post请求进行登录,本地测试是通过的,也就是能正常登录,但云端测试一直无法正常登录.

const cheerio = require("cheerio");
const superagent = require("superagent");
const cloud = require('wx-server-sdk')
cloud.init({
  env: cloud.DYNAMIC_CURRENT_ENV
});
var login_url = "http://us.nwpu.edu.cn/eams/login.action";
// 获取openId云函数入口函数
exports.main = async (event, context) => {
  // 获取基础信息
  const uid = event.sno;
  const pwd = event.password;
  var all_course_info = "";
  return new Promise((resolve, reject) => {
        superagent
          .post(login_url)
          .type("form")
          .set({
            "Content-Type": "application/x-www-form-urlencoded",
            Host: "us.nwpu.edu.cn",

          })
          .send({
            username: uid,
            password: pwd,
            encodedPassword: "",
            session_locale: "zh_CN",
          })
          .end(function (err, res) {

              console.log(res.text);
            var name_reg = /<p class="person_title_1" title="(\S*)">/g;
            var name = name_reg.exec(res.text);
            if (name) {
              name = name[1];
            } else {
              reject('出错了');
