我正在使用AngularJS和Django-cors-headers，然后给出"which is disallowed for cross-origin requests that require p

Question

我有一个Django本地服务器引用8000端口号，和一个本地nginx加载2080端口号的html页面。

我安装了django-cross-header包来解决跨域错误。

django-cross-header config in settings.py:

CORS_ALLOW_CREDENTIALS = True

CORS_ORIGIN_ALLOW_ALL = True
  CORS_ALLOW_HEADERS = (
         'x-requested-with',
         'content-type',
         'accept',
         'origin',
         'authorization',
         'x-csrftoken'
 )
  CORS_ORIGIN_WHITELIST = (
          '127.0.0.1:2080',
          'localhost:2080'
  )

配置angularjs:

portman.config(function ($routeProvider, $interpolateProvider, $httpProvider) {
     $routeProvider.otherwise('/');
     $httpProvider.defaults.headers.common['X-CSRFToken'] = csrftoken;
     $interpolateProvider.startSymbol('{$').endSymbol('$}');
     delete $httpProvider.defaults.headers.common['X-Requested-With'];
 });
 portman.constant('ip','http://127.0.0.1:8000/');

Get方法在angularjs中的代码是:

$http({
         method: 'GET',
         url: ip+'api/v1/dslam/events',
     }).then(function (result) {
        $scope.dslam_events = result.data;
     }, function (err) {
    });

请求头是:显示临时头文件

Accept:application/json, text/plain, */*
Origin:http://127.0.0.1:2080
Referer:http://127.0.0.1:2080/
User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.99 Safari/537.36
X-CSRFToken:ztouFO8vldho97bWzY9mHQioFk3j6h5V

加载页面后，我看到这个错误:

XMLHttpRequest cannot load http://127.0.0.1:8000/api/v1/dslam/events.The request was redirected to 'http://127.0.0.1:8000/api/v1/dslam/events/', which is disallowed for cross-origin requests that require preflight.

但是当我从控制台发送请求时，它会正确地从django服务器响应，我的jquery代码:

$.ajax({
            type: 'GET',
            url: "http://5.202.129.160:8020/api/v1/dslam/events/",
            success:function(data){
             console.log(data);
            }
        });

请求头是:

Accept:*/*
Accept-Encoding:gzip, deflate, sdch
Accept-Language:en-US,en;q=0.8,fa;q=0.6,pt;q=0.4
Connection:keep-alive
Host:127.0.0.1:8000
Origin:http://127.0.0.1:2080
Referer:http://127.0.0.1:2080/
User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.99 Safari/537.36

Answer 1

您需要将corsheaders添加到您已安装的应用程序中。

INSTALLED_APPS = [
    ...,
    'corsheaders',
    ...,
]

将corsmiddleware添加到中间件类中

MIDDLEWARE_CLASSES = [
    ...,
    'corsheaders.middleware.CorsMiddleware',
    ...,
]

最后你在url "/"的末尾缺少了一个斜杠。此外，您应该在http请求中添加csrf令牌，以便它能够工作使用不安全的http方法，如POST, PATCH, PUT和DELETE。

$http({
    method: 'GET',
    url: ip+'api/v1/dslam/events/',
    'X-CSRFToken' : $cookies.get('csrftoken')
}).then(function (result) {
    $scope.dslam_events = result.data;
}, function (err) {
});

为了让$cookies服务正常工作，你需要安装ngCookies angular模块，就这样。

尝试启用交叉原点

Answer 3

我和你有同样的问题。我只需要在httpd.conf和angular应用程序中添加以下设置。就是这样，只需执行以下步骤。

<IfModule mod_headers.c>
SetEnvIf Origin (.*) AccessControlAllowOrigin=$1
Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header set Access-Control-Allow-Credentials true
</IfModule> 

在angular应用中

angular.module('app', ['ngCookies'])
    .config([
   '$httpProvider',
   '$interpolateProvider',
   function($httpProvider, $interpolateProvider, $scope, $http) {
       $httpProvider.defaults.withCredentials = true;
       $httpProvider.defaults.xsrfCookieName = 'csrftoken';
       $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
   }]).
   run([
   '$http',
   '$cookies',
   function($http, $cookies) {
       $http.defaults.headers.post['X-CSRFToken'] = $cookies.csrftoken;
   }]);
