DJANGO的API跨域实现

Ajax跨域请求报错：XMLHttpRequest cannot load ''. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' ' is therefore not allowed access.

这种错误如何解决？

一种是JSONP。

一种是DJANGO上的第三方插件:django-cors，

基本设置：

django-cors-headers

A Django App that adds CORS (Cross-Origin Resource Sharing) headers to responses.

Although JSON-P is useful, it is strictly limited to GET requests. CORS builds on top of XmlHttpRequest to allow developers to make cross-domain requests, similar to same-domain requests. Read more about it here:http://www.html5rocks.com/en/tutorials/cors/
