我遇到了麻烦跨域CORS请求使用Chrome正常工作。

请求报头： 

Accept:*/*
Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3
Accept-Encoding:gzip,deflate,sdch
Accept-Language:en-US,en;q=0.8
Access-Control-Request-Headers:origin, content-type
Access-Control-Request-Method:POST
Connection:keep-alive
User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4

响应头： 

Access-Control-Allow-Headers:*
Access-Control-Allow-Origin:*
Allow:GET, POST, OPTIONS
Content-Length:0
Date:Tue, 30 Oct 2012 20:04:28 GMT
Server:BaseHTTP/0.3 Python/2.7.3

错误： 

XMLHttpRequest cannot load domain. Request header field Content-Type is not allowed by Access-Control-Allow-Headers.

，服务选项请求Python代码是： 

self.send_response(200)
self.send_header('Allow', 'GET, POST, OPTIONS')
self.send_header('Access-Control-Allow-Origin', '*')
self.send_header('Access-Control-Allow-Headers', '*')
self.send_header('Content-Length', '0')
self.end_headers()

看来访问控制允许来源通配符被忽略？

Answer 1:

在通配符支持Access-Control-Allow-Headers报头被添加到生活水平仅2016年5月，因此它可能不是所有的浏览器都支持。 对不执行这一尚未浏览器，它必须是一个精确匹配： https://www.w3.org/TR/2014/REC-cors-20140116/#access-control-allow-headers-response-header

如果您预计会有大量的头，你可以在值读取Access-Control-Request-Headers报头和回声该值重新在Access-Control-Allow-Headers报头。



Answer 2:

这些CORS头不支持*为值，唯一的办法就是更换*此：

常问问题：

  • 为什么Access-Control-Allow-Headers ， Access-Control-Expose-Headers ， Access-Control-Allow-Methods值是超长？

    那些不支持*语法，所以我已经收集了网络上最常见的（和异国情调的）头，以各种格式＃1 ＃2 ＃3 （我会更新列表不时）

  • 你为何用Header unset ______语法？

    GoDaddy的服务器（这我的网站上托管..）有一个奇怪的错误：如果头已经设置，之前的值将加入（而不是替换它）现有的..这样，我“预清洗”现有的值（其实只是AA 快速&&肮脏的解决方案）

  • 它是安全的，我用“原样”？

    嗯..大部分的答案是肯定的 ，因为.htaccess限制了头部的脚本（PHP，HTML，...）和资源（.JPG，.JS，.CSS）从下面的“文件夹” -location服务。 您可选择可能要删除的Access-Control-Allow-Methods行。 此外Connection ， Time-Zone ， Keep-Alive和DNT ， Accept-Ranges ， Vary ， X-UA-Compatible ， X-Frame-Options ， X-Content-Type-Options和X-Xss-Protection只是一个建议我”使用我的在线业务M ..随意删除这些呢？

从我采取上述评论



Answer 3:

我发现，访问控制允许报头：*应仅适用于“OPTIONS”请求设置。 如果您退货，POST请求，然后浏览器取消该请求（至少铬）

下面的PHP代码对我的作品

// Allow CORS
if (isset($_SERVER['HTTP_ORIGIN'])) {
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    header('Access-Control-Allow-Credentials: true');    
    header("Access-Control-Allow-Methods: GET, POST, OPTIONS"); 
}   
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    header("Access-Control-Allow-Headers: *");
}

我发现了一些误导性的反应类似的问题：

  • 服务器线程说，这是铬2年的错误：访问控制允许报头不匹配本地主机。 这是错误的：我可以正常使用CORS到我的本地服务器发布
  • 访问控制允许报头不接受通配符。 这也是错误的，通配符工作对我来说（我只使用Chrome测试）

这把我半天找出问题。

快乐编码



Answer 4:

从monsur引述

访问控制，允许报头头不允许通配符。 它必须是完全匹配： http://www.w3.org/TR/cors/#access-control-allow-headers-response-header 。

因此，这里是我的PHP解决方案。 

if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
  $headers=getallheaders();
  @$ACRH=$headers["Access-Control-Request-Headers"];
  header("Access-Control-Allow-Headers: $ACRH");
}


Answer 5:

这里是为nginx的咒语，里面

location / {
    # Simple requests
    if ($request_method ~* "(GET|POST)") {
      add_header "Access-Control-Allow-Origin"  *;
    }

    # Preflighted requests
    if ($request_method = OPTIONS ) {
      add_header "Access-Control-Allow-Origin"  *;
      add_header "Access-Control-Allow-Methods" "GET, POST, OPTIONS, HEAD";
      add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept";
    }

}
