跨域问题通用解决方案

设置一个中间件

class MiddlewareMixin(object):
    def __init__(self, get_response=None):
        self.get_response = get_response
        super(MiddlewareMixin, self).__init__()

    def __call__(self, request):
        response = None
        if hasattr(self, 'process_request'):
            response = self.process_request(request)
        if not response:
            response = self.get_response(request)
        if hasattr(self, 'process_response'):
            response = self.process_response(request, response)
        return response

class CORSMiddleware(MiddlewareMixin):

    def process_response(self,request,response):
        # 添加响应头

        # 允许你的域名来获取我的数据
        response['Access-Control-Allow-Origin'] = "*"

        # 允许你携带Content-Type请求头
        response['Access-Control-Allow-Headers'] = "Content-Type"

        # 允许你发送DELETE,PUT
        response['Access-Control-Allow-Methods'] = "DELETE,PUT"

        return response　

MiddlewareMixin是从源码copy过来的，自己有直接用自己的。

别忘了在setting里面配置。
