Question

我正在尝试向我的django tastypie资源执行put请求以更新用户信息。到目前为止，我可以发帖请求，但放不起作用。

在我的api.py中我有这个：

class UserResource(ModelResource):
   class Meta:
       queryset = User.objects.all()
       resource_name = 'auth/user'
       fields = ['username', 'email']
       authentication = BasicAuthentication()
       authorization = DjangoAuthorization()
       filtering = {
           "username": ('exact',),
       }

class UserSignUpResource(ModelResource):
   class Meta:
       object_class = User
       resource_name = 'register_user'
       fields = ['username', 'email' , 'password']
       allowed_methods = ['put','post']
       authentication = BasicAuthentication()
       authorization = DjangoAuthorization()
       queryset = User.objects.all()


    def obj_create(self, bundle, request=None, **kwargs):

         bundle = super(UserSignUpResource, self).obj_create(bundle)

用我来测试：

import urllib2, json

def post():

    def basic_authorization(user, password):
       s = user + ":" + password
       return "Basic " + s.encode("base64").rstrip()

    data = json.dumps({'username':'david_000', 'email':'davidupdat@gmail.com',   'password':'xxx','provider':'twitter','extra_data':{'access_token':'xxx','id':'xxx'}})

    req = urllib2.Request("http://192.168.1.114:8080/api/stats/register_user/",
    headers = {"Authorization": basic_authorization("xxx","xxx"),"Content-Type": "application/json"}, data = data)
    req.get_method = lambda:'PUT'
    f = urllib2.urlopen(req)

post()

我收到了这个错误：

Traceback (most recent call last):
File "test.py", line 18, in <module>
   post()
File "test.py", line 16, in post
   f = urllib2.urlopen(req)
File "/usr/lib/python2.7/urllib2.py", line 126, in urlopen
   return _opener.open(url, data, timeout)
File "/usr/lib/python2.7/urllib2.py", line 406, in open
   response = meth(req, response)
File "/usr/lib/python2.7/urllib2.py", line 519, in http_response
   'http', request, response, code, msg, hdrs)
File "/usr/lib/python2.7/urllib2.py", line 444, in error
   return self._call_chain(*args)
File "/usr/lib/python2.7/urllib2.py", line 378, in _call_chain
   result = func(*args)
File "/usr/lib/python2.7/urllib2.py", line 527, in http_error_default
   raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 400: BAD REQUEST

更新：

我试试这个，但它给了我同样的错误：

def obj_update(self, bundle, request=None, **kwargs):

    bundle = super(UserSignUpResource, self).obj_update(bundle)

有什么想法吗？在此先感谢！

这是因为您尝试发出一个put请求，但是put请求更新记录而不是创建新记录。 Tastypie将尝试执行obj_update方法，并期望在某个实例上执行。但是你正在向register_user / url发出请求，这显然不是一个对象实例，所以对这个url使用put请求根本没有意义。 PUT用于更新，而不是创建。

我只是通过一些修改来解决它。使用水合物方法我可以捕获请求方法（如放ou post）并处理我的请求。像这样：

class UserResource(ModelResource):
   class Meta:
       queryset = User.objects.all()
       resource_name = 'auth/user'
       fields = ['username', 'email','password','extra_data','provider']
       authentication = BasicAuthentication()
       authorization = DjangoAuthorization()
       filtering = {
            "username": ('exact',),
       }

   def prepend_urls(self):
       return [
           url(r"^(?P<resource_name>%s)/(?P<username>[\w\d_.-]+)/$" % self._meta.resource_name, self.wrap_view('dispatch_detail'), name="api_dispatch_detail"),
       ]

   def hydrate(self, bundle):
       request_method=bundle.request.META['REQUEST_METHOD']

       if request_method=='POST':
          #do something if you want
       elif request_method=='PUT':
          #do something if you want
       return bundle

测试我用这个创建了一个python文件：

def basic_authorization(user, password):
    s = user + ":" + password
    return "Basic " + s.encode("base64").rstrip()

url = 'http://192.168.1.114:8080/api/stats/auth/user/david/'
payload = {'username':'david', 'email':'david__@gmail.com', 'password':'xxxx','provider':'twitter','extra_data': {'access_token':'xxxx','id':'xxx'}}
headers = {'content-type': 'application/json'}
r = requests.put(url, data=json.dumps(payload), headers=headers, auth=HTTPBasicAuth('xxx', 'xxx')) 

print r.status_code
print r.history
print r.content

post()

它有效！

PUT请求django tastypie资源不起作用
