javascript - 尽管启用了 CORS，$http Angular 仍无法工作

Question

在深入研究 Angular 之前，我在服务器上进行了一次彻底的测试，以检查我的 CORS 是否已启用。使用此脚本。

    var xhr     = new XMLHttpRequest();
    var param   = 'name=mrA';
    xhr.open('POST','http://api.otamarket.local/api/cors.json',true);

    //Send the proper header information along with the request
    xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");

    xhr.onreadystatechange = function () {
      if (this.status == 200 && this.readyState == 4) {
        console.log('response: ' + this.responseText);
      }
    };
    xhr.send(param);

如您所见，它工作得很好。

但是当我通过 $http 使用 Angular 时

var http = "//api.otamarket.local/api/cors.json";
return $http.post(http,credentials);

我收到此错误。

这是 header 响应:

Remote Address:127.0.0.1:80
Request URL:http://api.otamarket.local/api/cors.json
Request Method:OPTIONS
Status Code:405 Method Not Allowed

这是我启用 CORS 的地方

<VirtualHost *:80>
    DocumentRoot "C:\Users\aldri_000\SkyDrive\Program  Experiment\websites\api.otamarket.local\public"
    ServerName api.otamarket.local
    Header set Access-Control-Allow-Origin "*"
<Directory "C:\Users\aldri_000\SkyDrive\Program Experiment\websites\api.otamarket.local">
    Options Indexes FollowSymLinks MultiViews
        AllowOverride all
        Order Deny,Allow
        Allow from all
        Require all granted
</Directory>
</VirtualHost>

这是端点:

public function post_cors()
{
   $rsp            = array();
   $rsp['rsp']     = 'CORS Work';
   return $this->response($rsp);
}

如您所见，我已在 apache 服务器的虚拟主机中启用了 CORS。它通过 XHR 工作，但我很困惑为什么它在这里不起作用。

谢谢。

Answer 1

我明白了，使用 $http 调用时内容类型未正确设置。尝试将 headers 属性添加到您的 $http 调用中，如下所示，

$http({
method: 'POST',
url: url,
data: $.param({fkey: "key"}),
headers: {'Content-Type': 'application/x-www-form-urlencoded'}

})
