跨网站请求 [英] cross-site request

问题描述

应该使用站点号1请求到站点号2.使第一个站点为localhost，站点号2为Internet上的真实服务器。在站点2有一个文件result.php，它需要GET请求：

Should be done with the site number 1 request to the site number 2. Let the number one site will be localhost, and the site number 2 - the real server on the Internet. At site 2 there is a file result.php, which takes GET-requests:


$ var = @ $ _ GET [ q'];

$ s = $ _GET ['s'];

$ typefile = $ _GET ['type'];



如果页面result.php提出请求，那么我们获取URL：result.php？q =％F4％FB％ E2& type = 1& search =％CF％EE％E8％F1％EA％21

$var = @$_GET['q'] ;
$s = $_GET['s'] ;
$typefile = $_GET['type'];

If the page result.php make a request, then we obtain the URL: result.php?q=%F4%FB%E2&type=1&search=%CF%EE%E8%F1%EA%21

如何更好地提出请求？有人可以告诉我一些例子来帮助吗？

How better to make a request? Can someone show me some examples to help? For 4 days I suffer, does not realize.

如果某个地方不清楚，请用英文。

If somewhere is not clear written excuse my bad English with.

推荐答案

我假设你是指Ajax？由于同源政策，您无法通过正常的ajax进行跨网站域请求。因此，localhost上托管的脚本只能向localhost发出请求。

I'm assuming you mean with Ajax? You can't make cross-site domain requests through normal ajax due to the same origin policy. As such, a script hosted on localhost, can only make requests to localhost.

现在，您可以使用 JSONP ，或带有填充的JSON。这允许您从任何源附加脚本文件到dom，以便代码可以在您的网站上执行。个人来说，我实际上从来没有使用它，我知道你必须信任脚本的来源，你不想在你的网站上运行任意代码。

Now, you can get around this with JSONP, or JSON with padding. This allows you to append a script file to the dom from any source so the code can execute on your site. Personally, I've actually never used it and I understand you have to trust the origin of the script, you don't want arbitrary code being run on your site.

简而言之，如果你想让localhost向site-2发出请求，你需要在site-2上托管一个由你的localhost加载的脚本并提出请求。

So in a nutshell, if you want localhost to make a request to 'site-2' you need to host a script on 'site-2' that gets loaded by your localhost and makes the request.
