Django 应用程序中的访问控制允许来源 [英] Access-Control-Allow-Origin in Django app

问题描述

我正在为基于 Django 的应用程序开发 Phonegap 应用程序，但在尝试进行 Ajax 调用时出现此错误:

I'm developing a Phonegap app for my Django based app, but when trying to make Ajax calls I get this error:

XMLHttpRequest cannot load http://domain.herokuapp.com/getcsrf/?tags=jquery%2Cjavascript&tagmode=any&format=json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. 

我怎样才能让我的 Django 应用程序允许某些 url 跨源?

How can I make it so my Django app allows cross origin for some urls?

这是我的 Ajax 代码:

Here's my Ajax code:

get: function() {
    $.getJSON("http://domain.herokuapp.com/getcsrf/",
    {
        tags: "jquery,javascript",
        tagmode: "any",
        format: "json"
    },
    function(data) {
        $.each(data.items, function(item){
            console.log(item);
            });
    });
}

推荐答案

默认情况下，Django 不提供提供跨域所需的标头.最简单的方法是使用这个为您处理它的 Django 应用程序:https://github.com/adamchainz/django-cors-headers

Django by default does not provide the headers necessary to provide cross origin. The easiest way would be to just use this Django app that handles it for you: https://github.com/adamchainz/django-cors-headers

• 添加到已安装的应用中
• 添加到中间件
• 然后是……

CORS_ALLOWED_ORIGINS = [
    "http://read.only.com",
    "http://change.allowed.com",
]

要支持全部允许，只需使用设置...CORS_ALLOW_ALL_ORIGINS = True然后在中间件或视图中对请求进行任何过滤.

to support allowing all, just use the setting... CORS_ALLOW_ALL_ORIGINS = True and then do any filtering of the request in middleware or in the view.
