You won't be able to do a cross-domain POST request in the browser.

您将无法在浏览器中执行跨域 POST 请求。

If you are making a JSONP call to access a cross-domain URL, you can use JQuery's getJSONmethod. This would allow you to make a GET request only. If you can submit your login information to the redirectURL using GET parameters, you could make this work.

如果您要进行 JSONP 调用以访问跨域 URL，则可以使用 JQuery 的getJSON方法。这将允许您仅发出 GET 请求。如果您可以使用 GET 参数将您的登录信息提交到 redirectURL，您就可以完成这项工作。

Note that POSTing to remote login forms is perhaps the best example of why browsers disallow cross-domain requests like this. You don't want a page that looks like your bank to be able to actually serve you data from your bank's website -- that would make a very effective phishing page.

请注意，POST 到远程登录表单可能是浏览器禁止此类跨域请求的最佳示例。您不希望看起来像您的银行的页面能够实际为您提供来自银行网站的数据——这将成为一个非常有效的网络钓鱼页面。

On the other hand, if you really want to work around this, you can write some server-side code that, given the input parameters, makes a post request to the redirectURL and funnels back the response.

另一方面，如果你真的想解决这个问题，你可以编写一些服务器端代码，给定输入参数，向 redirectURL 发出 post 请求并返回响应。

Please tell me you are not writing a phishing page.

请告诉我您不是在编写网络钓鱼页面。

One way to do it is to use your server as a proxy:

一种方法是使用您的服务器作为代理：

AJAX Request          -> Your server -> Server of interest

AJAX Response Handler <- Your server <- Server of interest

JSONP is not really Ajax in a way that it does not use XMLHttpRequestbut a dynamic scriptelement. jQuery makes this transparent but JSONP still requires the following to work:

从某种意义上说，JSONP 并不是真正的 Ajax，XMLHttpRequest而是一种动态script元素。jQuery 使这变得透明，但 JSONP 仍然需要以下内容才能工作：

1. HTTP GETonly, you can't use POSTs
2. the server needs to support it by wrapping the response in a call to the callbackyou specify

1. GET仅限HTTP ，不能使用POSTs
2. 服务器需要通过将响应包装在对callback您指定的调用中来支持它

Check if the URL you request supports JSONP and change the call to an HTTP GET.

检查您请求的 URL 是否支持 JSONP 并将调用更改为 HTTP GET。

If you do control the remote server, too, in recent browsers (IE8, FF3.5) you can overcome the cross-domain obstacle:

如果你也控制远程服务器，在最近的浏览器（IE8、FF3.5）中你可以克服跨域障碍：

IE's XDomainRequest methodand the W3C's and Mozillas Origin-Header.

IE 的 XDomainRequest 方法以及W3C 和 Mozillas 的 Origin-Header。

In short, if your server sends back the HTTP header

简而言之，如果您的服务器发回 HTTP 标头

Access-Control-Allow-Origin: *

with the AJAX response, IE and Mozilla will accept it, even if the request stems from a different domain. You can narrow down allowed requesting domains by replacing the *with them.

有了 AJAX 响应，IE 和 Mozilla 就会接受它，即使请求来自不同的域。您可以通过替换*它们来缩小允许的请求域的范围。

"I need to do cross domain Ajax request"

“我需要做跨域ajax请求”

You can't do that, unless:

你不能这样做，除非：

• you are using grease monkey
• you are making a jsonp request which isnt really ajax

• 你在用油猴
• 您正在发出一个实际上不是 ajax 的 jsonp 请求
