我的字节输入在Python中不正确（无法转换为JSON）***解决方案***

Question

[基本上，如果您对它发出POST请求，则会调用此API端点。问题是由于某种原因，我无法将字节转换为JSON，因此可以访问数据。

我的代码：

@api_view(['POST'])
def create_user(request):
    """ POST = Create user. """
    # Check that a username with this email doesn't already exist
    try:
        data = {}
        print("IS IT WORKING...?")
        print(type(request.body))
        print(request.body)
        # Use double quotes to make it valid JSON
        my_json = request.body.decode('utf8').replace("'", '"')
        print("MY_JSON:")
        print(my_json)
        data = json.loads(my_json)
        print("DATA:")
        print(data)
        s = json.dumps(data, indent=4, sort_keys=True)
        print("s:")
        print(s)
    except User.DoesNotExist:
        print("PLS WORK ON CONSOLE")
    return Response(status=status.HTTP_409_CONFLICT)

我尝试使用邮递员向我的路径users/create/发出POST请求，但是当我打印request.body以查看我的POST请求的内容时，该请求的格式设置不正确，带有许多随机数字和破折号。这使我无法将其转换为JSON。这是具有email和password字段的简单POST请求。

这是奇怪的格式：https://gyazo.com/fa1cc2f04637c02f79fe59790153ae40

这是“ json”在我解码并用双引号转换后的样子（请注意奇怪的破折号和数字）：https://gyazo.com/3ca41106117a4e9acdd96929469313a1

此后，由于data = json.loads(my_json)导致错误，因为输入的格式不正确。

错误消息：

编辑：好的，所以我找到了解决方案。在邮递员中，您可以将数据发送为form-data，也可以发送为raw。我使用的是form-data，我想这简直毁了一切，创造了所有怪异的-----和整数。我切换到raw并直接输入JSON格式和我的代码，现在可以使用！所有的！但是我完全不明白为什么。我只是有一种直觉，就是我发送数据的方法根本不正确。有人可以解释吗？
