亲爱的,我的问题不重复。
代码:
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
...
代码:
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);
我在同一个URL响应中尝试使用XMLHttpRequest:
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-*
标题。
但是当ajax用XMLHttpRequest到php服务器时,每件事都是好的。
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服务器还可以:
<?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
有什么问题?为什么php服务器都可以,nodojs都没有,为什么jquery ok在任何服务器上?
