Python中的字节输入不正确（不能转换为JSON）

基本上，我有一个API端点，如果您向它发出POST请求，它将被调用。问题是出于某种原因，我无法将字节转换为JSON以便访问数据

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)

我试图使用邮递员向我的路径

用户/create/

发出POST请求，但当我打印

request.body

以查看我的POST请求的内容时，它的格式不正确，带有大量随机数字和破折号。这使我无法将其转换为JSON。这是一个带有

电子邮件

和

密码

字段的简单POST请求

这就是奇怪的格式：

这就是“json”在我解码并用双引号转换后的样子（注意奇怪的破折号和数字）：

之后，由于输入格式不正确，导致

data=json.loads（my_json）

出错

错误消息：

我已经使用这些SO帖子（，）让我了解了我现在的处境（意识到我的输入是错误的！）。

编辑：好的，我找到了解决方案。在Postman中，您可以将数据发送为

表单数据

，也可以发送为

原始数据

。我当时使用的是

表单数据

，我想这会毁掉一切，并产生所有奇怪的------和整数。我切换到

raw

，直接输入JSON格式，我的代码现在可以工作了！全部！但我完全不明白为什么。我只是有一种预感，我发送数据的方法根本不正确。有人能解释一下吗

您好，如果这个问题有错误（打字错误或简单错误），请删除它。如果没有，但您有答案，请将您的答案作为您自己问题的答案发布，并用复选标记选择。谢谢，我会这样做（您是对的）。：）我只能在两天后接受我自己的答案！您可以尝试将POST请求上的

Content-Type

头设置为

application/json；字符集=utf-8

。这应该正确编码json。
