反应客户端代码-使用请求保证在标题中发送用户名和密码

var password = values.password;
  var email = values.email;
request
        .head(
          "https://us-central1-simplineet-754e8.cloudfunctions.net/CreateUserauth"
        )
        .set('Content-Type','application/x-www-form-urlencoded')
        .auth(email,password,false)
        .query(dataobj)
        .then(res => {
          console.log(res);
          if (res.statusCode === 200) {
            console.log("statusText",res.body);

          } else {
            console.log("statusText",res.statusText);

          }
        })
        .catch(err => {});

后端-Google Cloud功能可以处理来自客户端的基本身份验证请求

   const express = require('express');
    const app = express();
    const cors = require('cors');
    app.use(cors({origin: true}));

    exports.CreateUserauth = functions.https.onRequest((request,response) => {
     var corsFn = cors();
     corsFn(request,response,function ()  {
        // Request Header
            response.setHeader('access-Control-Allow-Methods','GET,POST,OPTIONS,PUT,PATCH,DELETE');
            response.setHeader('access-Control-Allow-Headers','X-Requested-With,content-type');
            response.setHeader('access-Control-Allow-Credentials',true);
            response.setHeader('access-control-allow-origin','*');


        var auth = require('basic-auth') // basic-auth NPM  package to extract username and password from header
        var user = auth(request)  
        var email = user.name; // Getting username from Auth
        var password = user.pass; // Getting password from Auth
        var username = request.query.username;

        response.send('Hello from Firebase!');  // Not getting this response in Client 
     });

    });

响应进入客户端：

Response {req: Request,xhr: XMLHttpRequest,text: null,statusText: "",statusCode: 200, …}
