jquery - Django-cors-headers 不工作

Question

我的 django 版本是 1.8.6。我已将 corsheaders 文件夹复制到项目文件夹中。我已经 pip 安装了 django-cors-headers(版本 1.1.0)。这是我的设置.py:

    INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'MyWebsite_app',
    'storages',
    'rest_framework',
    'corsheaders',
)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
)

CORS_ORIGIN_ALLOW_ALL = True

这是我的 jquery:

function getLeague() {
$.ajax({
    url: 'http://otherdomain.ashx?username=xxx&password=xxx&sportsBook=xxx&sportsType=xxx&gameType=xxx',
    type: 'GET',
    dataType: 'json',
    success: function(data) {
        alert('Success');
    },
    error: function(data) {
        alert('Fail');
    }
    });
}

它在执行 getLeague() 时一直提示“失败”。当我看到控制台时，它显示“XMLHttpRequest 无法加载 http://otherdomain.ashx?username=xxx&password=xxx&sportsBook=xxx&sportsType=xxx&gameType=xxx。请求的源上不存在 Access-Control-Allow-Origin header ”。我应该在 urls.py 还是 view.py 中添加一些代码？谢谢。

最好在您的应用程序中创建一个代理，该代理将调用另一个域并将数据返回给您:

function getLeague() {
  $.ajax({
    url: '/crossdomainData',
    type: 'GET',
    dataType: 'json',
    success: function(data) {
        alert('Success');
    },
    error: function(data) {
        alert('Fail');
    }
    });
}

因为你使用的是django，你可以导入这个Django HTTP Proxy .

Introduction

Django HTTP Proxy provides simple HTTP proxy functionality for the Django web development framework. It allows you make requests to an external server by requesting them from the main server running your Django application. In addition, it allows you to record the responses to those requests and play them back at any time.

这里有另一个选项 taken from this post由 @dvcrn 回答.

import urllib2
    def crossdomainData(request):
        url = "http://otherdomain.ashx?username=xxx&password=xxx&sportsBook=xxx&sportsType=xxx&gameType=xxx"
        req = urllib2.Request(url)
        response = urllib2.urlopen(req)
        return HttpResponse(response.read(), content_type="application/json")
