Django'CSRFCheck'对象没有属性'process_request' [英] Django 'CSRFCheck' object has no attribute 'process_request'

问题描述

一切正常，直到突然在我的API上实现 DjangoObjectPermissions 时出现上述错误。

It was all ok till suddenly I got the above error while implementing DjangoObjectPermissions on my APIs.

之前即使我的生产环境正常，它也可以正常工作。我只在本地环境中看到此错误。

Before this It was working ok even my production environment it is working fine. I am seeing this error on my local environment only.

根据此答案，错误会消失，但是我需要知道为什么？

according to this answer, the error would go away, but I need to know why?

请让我知道我应该在此帖子中添加哪些信息。

Please let me know what information should I add to this post.

推荐答案

在try_csrf（）中添加try / except语句

请注意，此错误源自rest_framework /authentication.py（在SessionAuthentication类中），方法execute_csrf（）。 execute_csrf（）方法将初始化变量，check = CSRFCheck（），下一行显示 check.process_request（request）。

Note that this error originates from rest_framework/authentication.py, within class SessionAuthentication, method enforce_csrf(). The enforce_csrf() method iinitiates variable, check = CSRFCheck(), and the next line says "check.process_request(request).

如果使用IDE，您将很快注意到CSRFCheck（）没有此属性/方法，因此出现了错误。许多开发人员会迅速告诉您升级到django> = 1.11.6，但是您肯定会遇到相同的错误。问题，我正在使用django 1.11.6和rest_framework 3.9.1。

If using an IDE, you'll quickly notice that CSRFCheck() doesn't have this attribute/method thus the error. Many developers will quickly tell you to upgrade to django >= 1.11.6 but you are bound to run into the same error. For that matter, am using django 1.11.6 and rest_framework 3.9.1.

因此，请尝试使用此补救方法，它对我有用。请使用try / except语句。在下面的rest_framework / authentication.py中，检查= CSRFCheck（），
添加此...

So try this remedy, it worked for me. Use the try/except statement. Go within the rest_framework/authentication.py, below, check = CSRFCheck(), add this...

def enforce_csrf(self, request):
   ...
   try:
       check.process_request(request)
   except:
       pass

这是什么意思：
声明 check变量后，调用（尝试）此方法 process_request（） ，如果它不起作用（除外），则通过。您将实现两件事这样做：一，您实际上保持了rest_framework源代码的兼容性（假定升级到django的其他版本可能可以解决此问题），二，您可以获得有效的代码（很好！，尤其是在工作敏捷的情况下）

What the lines say is this: After declaring the "check" variable, call (try) this method "process_request()" and if it does not work (except), just pass. You achieve two things with this: One, you literally leave the rest_framework source code compatible (given that upgrading to further versions of django "might" solve this), and two, you get working code (nice!!, especially if working Agile)
