Question

我正在为我的ReactJS应用程序创建一个单独的Django REST-api。我正在向端点调用访存POST API以注册用户。我不确定错误的含义，因为我的状态为200。

我的终端回溯：

[30/Jan/2019 10:09:27] "OPTIONS /newuser/ HTTP/1.1" 200 108

ConnectionResetError: [Errno 54] Connection reset by peer

我的ReactJS代码：

var csrftoken = document.getElementById('token').getAttribute('value');
    console.log(csrftoken);
fetch('http://localhost:8000/newuser/', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
    'X-CSRFToken': csrftoken
  },
  body: JSON.stringify({
    username: this.state.username,
    password: this.state.password,
  }),
}).then(
  (response) => {
    console.log("We did it!");
    console.log(response.json);
  }
).catch(
  (error) => {
    console.log(error);
  }
);

我的Django查看代码：

class SignUp(APIView):

parser_classes = (JSONParser,)
permission_classes = (AllowAny,)

def post(self, request, format = None):

    print(request.data, " is request data")
    if 'username' not in request.data or 'password' not in request.data:
        raise ParseError('Username or password not provided')
    if request.user.is_authenticated:
        login(request, user)
        returnData = UserSerializer(user)
        return Response(returnData.data)

    if 'username' not in request.data or 'password' not in request.data:
        raise ParseError('Username or password not provided')

    username = request.data['username']
    password = request.data['password']
    print(username, password)

    user = User.objects.create_user(username = username, password = password)

    login(request, user)
    returnData = UserSerializer(user)
    print(returnData.data)
    return Response(returnData.data)

响应回调应接收returnData.data，但应在控制台中返回TypeError。

错误[Errno 54] Connection reset by peer表示加载资源（在此示例中为ajax响应）已中断，但不是由于服务器故障。这意味着连接断开或客户端中断了该资源的加载。

对于您而言，这可能意味着您的JavaScript代码或浏览器本身有问题。在浏览器调试器中检查“网络”标签，以找到该中断的连接，这应该有助于对其进行跟踪。

尽管状态为200，但处理表单请求时发生异常
