我不断收到以下错误：
POST http://127.0.0.1:8000/api/creator_signup/ 400 (Bad Request)
每当我尝试将数据从AngularJS应用程序发布到Django后端时。
在客户端，我使用此代码编写了以下帖子（https://imgur.com/a/syt64）：
function registerCreator(creatorData) {
var url = envService.read('apiUrl') + "/creator_signup/";
var dataJSON = {
first_name: creatorData.firstName,
last_name: creatorData.lastName,
email: creatorData.email,
youtube_channel_username: creatorData.username,
youtube_channel_url: creatorData.url,
youtube_channel_title: creatorData.title,
youtube_channel_description: creatorData.description,
photo: creatorData.photo,
youtube_channel_start_date: creatorData.startDate,
keywords: creatorData.keywords,
no_of_subscribers: creatorData.noOfSubscribers,
no_of_videos: creatorData.noOfVideos,
no_of_views: creatorData.noOfViews,
no_of_likes: creatorData.noOfLikes,
no_of_dislikes: creatorData.noOfDislikes,
location: creatorData.location,
avg_views: creatorData.avgViews,
gender: 0,
password: creatorData.password
};
var req = {
method: 'POST',
url: url,
headers: {
'content-type': 'application/x-www-form-urlencoded',
},
data: dataJSON
};
$log.info(req);
return ($http(req).then(handleSuccess, handleError));
}
function handleSuccess(response) {
return response.data;
}
function handleError(response) {
if (!angular.isObject(response.data) || !response.data.message) {
return($q.reject('An unknown error occurred.'));
}
return($q.reject(response.data.message));
}
在服务器端，我有：

我认为问题出在views.py和serializers.py代码中，但是我不确定如何进行诊断。
在客户端，一切都在请求之前注销，并且一切正常。
参考方案
尝试在'content-type': 'application/x-www-form-urlencoded'功能中将'content-type': 'application/json'更改为registerCreator。在Django方面，数据将在request.body下可用，因此您的CreatorSignup视图应如下所示：
import json
...
class CreatorSignup(generics.CreateAPIView):
"""
Creator signup
HTTP POST
"""
queryset = Creator.objects.all()
serializer_class = CreatorSignupSerializer
def post(self, request, *args, **kwargs):
return self.create(request, *args, **kwargs)
def create(self, request, *args, **kwargs):
request_body_dict = json.loads(request.body)
serializer = self.get_serializer(data=request_body_dict)
serializer.is_valid(raise_exception=True)
return Response(data=serializer.data, status=status.HTTP_201_CREATED)
您还需要在发送JSON之前将其转换为字符串，因此在RegisterCreator函数中，将data: dataJSON更改为data: JSON.stringify(dataJSON)。
