问题描述

我正在使用 Backbone 和 Slim PHP 框架.我正在尝试将信息发布到我的 API，但是 Access-Control-Allow-Headers 不断给我带来问题...

I'm using Backbone and the Slim PHP framework. I'm trying to post information to my API, however Access-Control-Allow-Headers keeps causing me problems...

我的控制台显示:

    OPTIONS http://api.barholla.com/user/auth 405 (Method Not Allowed) zepto.min.js:2
XMLHttpRequest cannot load http://api.barholla.com/user/auth. Request header field Content-Type is not allowed by Access-Control-Allow-Headers.

我的标题是:

Request URL:http://api.barholla.com/user/auth
Request Method:OPTIONS
Status Code:405 Method Not Allowed
Request Headersview source

我的精简 index.php 文件中的标题是:

My headers in my slim index.php file are:

$res = $app->response();
$res->header('Access-Control-Allow-Origin', '*');
$res->header("Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS");

处理帖子数据:

$app->post('/user/auth', function () use ($app) {
//code here
});

在我的 javascript(我正在使用主干框架)中，我的代码是:

In my javascript (i'm using the backbone framework) my code is:

 App.userAuth = new App.UserAuthModel({
  username: $('#username').val(),
  password: hex_md5($('#password').val())
});

App.userAuth.save({}, {
  success: function(model, resp) {
    console.log(resp);
  },
  error: function(model, response) {
    console.log(response);
  }
});

任何帮助将不胜感激，我已经坚持了很长时间！

Any help would be much appreciated, I've been stuck on this for ages!

推荐答案

我有一个类似的跨域 POST 问题(实际上除了 GET 之外的所有标头).以下解决了它:

I had a similar cross domain POST problem (in fact with all headers except GET). The following resolved it:

if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']) && (   
       $_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD'] == 'POST' || 
       $_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD'] == 'DELETE' || 
       $_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD'] == 'PUT' )) {
             header('Access-Control-Allow-Origin: *');
             header("Access-Control-Allow-Credentials: true"); 
             header('Access-Control-Allow-Headers: X-Requested-With');
             header('Access-Control-Allow-Headers: Content-Type');
             header('Access-Control-Allow-Methods: POST, GET, OPTIONS, DELETE, PUT'); // http://stackoverflow.com/a/7605119/578667
             header('Access-Control-Max-Age: 86400'); 
      }
  exit;
}
