問題描述

在我的應用程序中，我正在創建從 HTTP 到 HTTPS 的 AJAX 請求.這意味著我需要 CORS.因此，我向 jQuery.ajax 添加了一些標頭和參數并對其進行了測試.在 Firefox 中一切正常，但在 Chrome 中卻不行.Chrome 殺死"每個預請求的請求(選項).

in my app I'm creating AJAX request from HTTP to HTTPS. This means I need CORS. So I add some headers and params to jQuery.ajax and test it. In Firefox everythings works OK, but in Chrome not. Chrome "kill" every preflighed request (OPTIONS).

jQuery 腳本:

$(document).on('click', 'a.ajax', function(e) {
    e.preventDefault();
    $.ajax(this.href, {
        type: 'GET',
        dataType: 'json',
        crossDomain: false,
        headers: {'X-Requested-With': 'XMLHttpRequest'},
        xhrFields: {
            withCredentials: true
        }
    });
    return false;
});

HTTP 轉儲:

> OPTIONS /foo HTTP/1.1
> User-Agent: curl/7.29.0
> Host: local.bar.cz
> Accept: */*
> Access-Control-Request-Headers:accept, origin, x-requested-with
> Access-Control-Request-Method:GET
> Origin:http://local.bar.cz
> 
< HTTP/1.1 204
< Server: nginx/1.2.7
< Date: Wed, 27 Feb 2013 15:06:54 GMT
< Content-Type: text/html; charset=utf-8
< Connection: keep-alive
< X-Powered-By: Nette Framework
< X-Frame-Options: SAMEORIGIN
< Access-Control-Allow-Origin: http://local.bar.cz
< Access-Control-Allow-Credentials: true
< Access-Control-Allow-Headers: accept, origin, x-requested-with
< Access-Control-Allow-Methods: OPTIONS, GET, POST, HEAD
< 

有人知道為什么 chrome 會終止這個請求嗎?

any one knows why chrome kill this request?

推薦答案

可能你的 https 服務器有一個不受信任的證書.如果是這樣，請先嘗試使用瀏覽器訪問該 URL，并接受不受信任的連接.

Maybe your https server has an untrusted certificate. If so, try accessing to the URL with your browser first, and accepting the untrusted connection.
