如何使用jQuery进行子域Ajax调用(不使用iFrame) [英] How to make a subdomain ajax call with jQuery (without iFrames)

问题描述

site.com/api/index.php 是我需要ajax请求去的地方.从 site.com/sub/可以正常运行请求，但是 sub.site.com 会将请求发送到 sub.site.com/api/index.php 显然不存在...我已经让Google和StackOverflow摆脱了困境，但似乎找不到有效的答案.

site.com/api/index.php is where I need the ajax request to go. From site.com/sub/ the request works perfectly but sub.site.com is sending the request to sub.site.com/api/index.php which obviously does not exist... I've Google and StackOverflowed the hell out of the question, but can't seem to find an answer that works.

代码:

var jQuery_ajax = {
   url: "site.com/api/index.php",
   type: "POST",
   data: $.param(urlData),
   dataType: "json"
}


var request = $.ajax(jQuery_ajax);

最常见的答案是将 document.domain 设置为常规站点，但这似乎无济于事...我也看到了有关iFrame的答案，但是我想不惜一切代价远离iFrame.

The most common answer was to set document.domain to the regular site, but that does not seem to do anything... I've also seen answers talking about iFrames, but I want to stay away from iFrames at all costs.

document.domain = "site.com";

**注意:一切都在同一台服务器上.

** Note: everything is on the same server.

Hacky解决方案:将sub.site.com/api/index.php设置为简单读取的文件

HACKY SOLUTION: made sub.site.com/api/index.php a file that simply reads

include_once("$path2site/api/index.php");

推荐答案

将URL纠正为http://site.com/api/index.php后，请尝试将以下内容添加到api/index.php:

Once you've corrected the URL to http://site.com/api/index.php try adding the following to api/index.php:

header("Access-Control-Allow-Origin: http://sub.site.com");

e:这样做有可能也会禁止site.com的使用；我没有找到提供两个值的方法，因此您可能需要一种方法来告诉它使用哪个站点，例如index.php的?sub = 1 arg

e: it's possible that doing so may disallow use from site.com as well; I'm not seeing a way to provide two values, so you may need a way to tell it which site to use, like a ?sub=1 arg to index.php
