Question

我已经对此进行了测试，并且我的代码可以在本地运行，但是当我推送到服务器时，出现了CORS错误。这是同一个域，我相信我已正确配置了CORS，但无法解决此错误。任何帮助将不胜感激。

我将我的快速服务器设置为端口80，并在端口80上进行侦听。呼叫肯定命中了它，但由于以下错误而被拒绝：

跨域请求被阻止：“同源起源”策略禁止读取https://website.com:80/nameid处的远程资源。（原因：CORS请求未成功）

express / config / routes.js

var express = require('express')
var cors = require('cors')
var app = express()

app.use(cors())
var xmldoc = require('xmldoc');
var DOMParser = require('dom-parser');


module.exports = function (app, config) {

  app.get('/', function (req, res) {
      res.redirect('/home')
  });


app.post('/nameid', cors(), function (req, res) {
nameidjson = ({ 'nameid': nameid});
console.log(nameidjson);
console.log(JSON.stringify(nameidjson));
   res.send(JSON.stringify(nameidjson));
  })
    
  

};

angular / service.ts

    getNameID(): Observable<NameIDResult[]> {
    const url = 'https://website.com:80/nameid';
    const data = ({  });
    return this._http.post(url, data)
    .pipe(
      map((res) => {
        console.log(res);
        return <NameIDResult[]> res;
      })
    );
  }

使用Angular和Express在同一个域上获取CORS错误
