DRF - 访问请求的POST数据 [英] DRF - access request's POST data

问题描述

我使用这样的邮递员向本地服务器请求：

您可以看到这是一个帖子请求。在我看来（ APIView ）我需要访问json数据。但是当我尝试：

  request.POST 
＃< QueryDict：{}> 
  

或

  request.data＃¿ 
＃AttributeError：'WSGIRequest'对象没有属性'data'
  

唯一的方法我可以看到发送的数据是当我访问

  request.body 
＃'{\\\
token ：6J3qG4Ji2Jw44eIklKvPYxUgclfGRWHZDKG，\city：Port Orange，\\\
state：FL，\\\
formatted_address：Peach Blossom Blvd 5329，\_zip 32128\\\
'
  

但这是一个'str' / code>

 >>> type（request.body）
< type'str'> 
  

我试图访问请求的数据在 dispatch（）方法。我可以这样做：

  req = self.initialize_request（request）
  pre> 
 
 
这将返回一个 rest_framework.request.Request 对象，我可以访问请求数据。但是我不能调用
  super（FaveoAPIView，self）.dispatch（request，* args，** kwargs）
  
因为我得到：
  {
status_code：400，
object：格式错误的请求，
success：false 
} 
  
我不明白为什么，我猜当我调用 self.initialize_request（）某事改变。任何想法？
解决方案
我相信你应该可以覆盖 initial（）方法，以实现您正在尝试的内容。来自 APIView 类的docstring显示为：
 
在调用方法处理程序之前运行需要发生的任何事情

  
所以，它看起来像：
  class FaveoAPIView（APIView）：
 
 def initial 
 super（FaveoAPIView，self）.initial（request，* args，** kwargs）
＃操作request.data到你心中的内容
  
在 APIView 中，这是在您的方法之前立即调用处理程序。
 
I do a request to my local server using postman like this:



As you can see it's a post request. In my view (APIView) I need access to the json data. But when I try:
request.POST
# <QueryDict: {}>    
or 
request.data  # ¿?
# AttributeError: 'WSGIRequest' object has no attribute 'data'
The only way I can see the sent data is when I access to
request.body
# '{\n    "token": "6J3qG4Ji2Jw44eIklKvPYxUgclfGRWHZDKG",\n    "city": "Port Orange",\n    "state": "FL",\n    "formatted_address": "Peach Blossom Blvd 5329",\n    "_zip": "32128"\n}'
But this is a 'str'
>>> type(request.body)
<type 'str'>
I an trying to access to the request's data in dispatch() method. I can do this:
req = self.initialize_request(request)
This returns a rest_framework.request.Request object and I can access to request data. But then I can't call
super(FaveoAPIView, self).dispatch(request, *args, **kwargs)
Because I get:
{
  "status_code": 400,
  "object": "Malformed request.",
  "success": false
}
I can'r understand why, I guess that when I call self.initialize_request() something change. Any idea?
解决方案
I believe you should be able to override the initial() method on your view in order to achieve what you're attempting. The docstring from the APIView class reads:
"""
Runs anything that needs to occur prior to calling the method handler.
"""
So, it would look something like:
class FaveoAPIView(APIView):

    def initial(self, request, *args, **kwargs):
        super(FaveoAPIView, self).initial(request, *args, **kwargs)
        # Manipulate request.data to your heart's content here
In APIView, this is called immediately before your method handler.
