XMLHttpRequest和jQuery AJAX方法之间的响应头区别(Response header difference between XMLHttpRequest and jQuery AJAX method)

XMLHttpRequest和jQuery AJAX方法之间的响应头区别(Response header difference between XMLHttpRequest and jQuery AJAX method)

我的问题不重复。

码：

var data = {'userId': window.cookie.get('userId'), 'sessionId': window.cookie.get('sessionId')} $.post(window.DbUrl + '/test', data, function (e) { console.log(e); });

我尝试用jQuery post发送ajax，响应是：

Access-Control-Allow-Credentials:true Access-Control-Allow-Headers:Origin, Content-Type, X-Auth-Token, Authorization Access-Control-Allow-Methods:GET, POST, PATCH, PUT, DELETE, OPTIONS Access-Control-Allow-Origin:https://localhost:8080 Connection:keep-alive Content-Length:1011 ...

码：

var formdata = new FormData(); formdata.append('sessionId', window.cookie.get('sessionId')); formdata.append('userId', window.cookie.get('userId')); var ajax = new XMLHttpRequest(); ajax.upload.addEventListener("progress", selff.myProgressHandler, false); ajax.addEventListener("load", myCompleteHandler, false); ajax.addEventListener("error", myErrorHandler, false); ajax.addEventListener("abort", myAbortHandler, false); ajax.open("POST", window.DbUrl + '/test',true); ajax.send(formdata);

我尝试与XMLHttpRequest在同一个URL响应是：

Allow:POST Connection:keep-alive Content-Length:4 Content-Type:text/html; charset=utf-8

在nodejs express服务器中，缺少Access-Control-Allow-*标头。

但是，当使用XMLHttpRequest到php服务器的每一件事情都是好的。

nodejs服务器：

app.post('/test', function (req, res) { res.setHeader('Access-Control-Allow-Origin', 'https://localhost:8080'); res.setHeader('Access-Control-Allow-Credentials', 'true'); res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PATCH, PUT, DELETE, OPTIONS'); res.setHeader('Access-Control-Allow-Headers', 'Origin, Content-Type, X-Auth-Token, Authorization'); res.end('welcome'); });

PHP服务器是好的：

<?php header('Access-Control-Allow-Origin: https://localhost:8080'); header('Access-Control-Allow-Credentials: true'); header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS'); header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token, Authorization'); ?>wellcome

问题是什么？ 为什么PHP服务器是好的两个nodojs不是，为什么jQuery在任何服务器上都可以？

Dears my problem is not duplicate.

code:

var data = {'userId': window.cookie.get('userId'), 'sessionId': window.cookie.get('sessionId')} $.post(window.DbUrl + '/test', data, function (e) { console.log(e); });

I try to send ajax with jquery post and response is:

Access-Control-Allow-Credentials:true Access-Control-Allow-Headers:Origin, Content-Type, X-Auth-Token, Authorization Access-Control-Allow-Methods:GET, POST, PATCH, PUT, DELETE, OPTIONS Access-Control-Allow-Origin:https://localhost:8080 Connection:keep-alive Content-Length:1011 ...

code:

var formdata = new FormData(); formdata.append('sessionId', window.cookie.get('sessionId')); formdata.append('userId', window.cookie.get('userId')); var ajax = new XMLHttpRequest(); ajax.upload.addEventListener("progress", selff.myProgressHandler, false); ajax.addEventListener("load", myCompleteHandler, false); ajax.addEventListener("error", myErrorHandler, false); ajax.addEventListener("abort", myAbortHandler, false); ajax.open("POST", window.DbUrl + '/test',true); ajax.send(formdata);

I try with XMLHttpRequest in same URL response is:

Allow:POST Connection:keep-alive Content-Length:4 Content-Type:text/html; charset=utf-8

In the nodejs express server, missing Access-Control-Allow-* headers.

But when ajax with XMLHttpRequest to php server every thing is Ok.

nodejs server:

app.post('/test', function (req, res) { res.setHeader('Access-Control-Allow-Origin', 'https://localhost:8080'); res.setHeader('Access-Control-Allow-Credentials', 'true'); res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PATCH, PUT, DELETE, OPTIONS'); res.setHeader('Access-Control-Allow-Headers', 'Origin, Content-Type, X-Auth-Token, Authorization'); res.end('welcome'); });

php server is ok:

<?php header('Access-Control-Allow-Origin: https://localhost:8080'); header('Access-Control-Allow-Credentials: true'); header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS'); header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token, Authorization'); ?>wellcome

What is the problem? why php server is ok both nodojs is not, why jquery ok in any server?

我不知道原因，但是如果你想修复它，请使用cors包。 由于软件包具有快速请求触发功能，因此请在发送手册之前发送标题。

I don't know the reason but use the cors package if you want to fix it. Because the package has trigger on express request, send header before you send manual.
