Question

当我的网站通过谷歌翻译运行时，我遇到了麻烦：我的服务器根本没有回复我的浏览器的AJAX请求，而不是单个标题。

请求网址如下：

https://translate.google.com/translate?depth=1&hl=en&rurl=translate.google.com&sl=en&tl=sq&u=https://www.example.com/

Google翻译会发送一个origin请求标头，其值为https://translate.googleusercontent.com。

我做了很多尝试，这里基本上是我试图通过PHP设置的标题响应：

header('Access-Control-Allow-Origin: https://translate.googleusercontent.com');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: X-Requested-With');
header('Access-Control-Allow-Origin: translate.googleusercontent.com');
header('Access-Control-Allow-Origin: googleusercontent.com');
header('Access-Control-Allow-Origin: google.com');

显然，*值最不安全，但没有工作需要进行更激烈的实验。我也（没有成功）将此添加到AJAX请求中：

//This is now removed due to research revealing this is why Chrome was making the request as 
//an HTTP OPTIONS method.
if (window.location.host!=domain) {xhr.setRequestHeader('Access-Control-Allow-Origin','*');}

我已将PHP设置为通过Google翻译请求向我发送$_SERVER转储：

Array
(
 [GATEWAY_INTERFACE] => CGI/1.1
 [HTTPS] => on
 [HTTP_ACCEPT] => *
 [HTTP_ACCEPT_CHARSET] => utf-8,*
 [HTTP_ACCEPT_ENCODING] => gzip,deflate,br
 [HTTP_CONNECTION] => Keep-alive
 [HTTP_HOST] => www.example.com
 [HTTP_USER_AGENT] => ***
 [HTTP_VIA] => 1.0 translate.google.com TWSFE/0.9
 [HTTP_X_FORWARDED_FOR] => [my IP], [my IP...again]
 [PATH] => /bin:***
 [PHPRC] => ***
 [QUERY_STRING] => query=index.php
 [REDIRECT_STATUS] => 200
 [REMOTE_ADDR] => 66.102.8.203 [Google Proxy]
 [REMOTE_PORT] => ***
 [REQUEST_METHOD] => GET
 [REQUEST_URI] => /
 [SCRIPT_FILENAME] => index.php
 [SCRIPT_NAME] => /index.php
 [SERVER_ADDR] => ***
 [SERVER_ADMIN] => ***
 [SERVER_NAME] => www.example.com
 [SERVER_PORT] => 443
 [SERVER_PROTOCOL] => HTTP/1.1
 [SERVER_SIGNATURE] =>
 [SERVER_SOFTWARE] => Apache
 [SSL_TLS_SNI] => www.example.com
 [UNIQUE_ID] => ***
 [PHP_SELF] => /index.php
 [REQUEST_TIME_FLOAT] => ***
 [REQUEST_TIME] => ***
)

Firefox使用HTTP POST方法正确发出请求。出于某种原因，Chrome使用HTTP OPTION方法发出AJAX请求...等等什么？这不是我的网站编码方式。

我怀疑服务器可能正在响应Google的初始请求服务器，而不是我的浏览器，尽管我不确定。 $_SERVER 包含$_SERVER['HTTP_X_FORWARDED_FOR']我的IP地址列出两次，但我不确定这一切是如何运作的。我猜这比普通的CORS请求要复杂一些。如何让我的服务器响应我的浏览器？

通过Google Translate访问网站时，没有服务器对AJAX请求的响应
