Django request.GET 添加额外的数据引用

Question

当我通过 Django request.GET 传递参数时，我在字典中得到了一个不需要的额外逗号。

我重定向到端点的编码数据：

/turnalerts/api/v2/statuses?statuses=%5B%7B%27conversation%27%3A+%7B%27expiration_timestamp%27%3A+%271735510680%27%2C+%27id%27%3A+%2757f7d7d4d255f4c7987ac3557bf536e3%27%2C+%27origin%27%3A+%7B%27type%27%3A+%27service%27%7D%7D%2C+%27id%27%3A+%27wamid.HBgNMjM0OTAzOTc1NjYyOBUCABEYEjdCMTJFNUZDNzNFQjkxQ0IyRQA%3D%27%2C+%27pricing%27%3A+%7B%27billable%27%3A+True%2C+%27category%27%3A+%27service%27%2C+%27pricing_model%27%3A+%27CBP%27%7D%2C+%27recipient_id%27%3A+%272349039756628%27%2C+%27status%27%3A+%27sent%27%2C+%27timestamp%27%3A+%271735424268%27%7D%5D

要求：

<rest_framework.request.Request: GET '/turnalerts/api/v2/statuses?statuses=%5B%7B%27conversation%27%3A+%7B%27expiration_timestamp%27%3A+%271735510680%27%2C+%27id%27%3A+%2757f7d7d4d255f4c7987ac3557bf536e3%27%2C+%27origin%27%3A+%7B%27type%27%3A+%27service%27%7D%7D%2C+%27id%27%3A+%27wamid.HBgNMjM0OTAzOTc1NjYyOBUCABEYEjdCMTJFNUZDNzNFQjkxQ0IyRQA%3D%27%2C+%27pricing%27%3A+%7B%27billable%27%3A+True%2C+%27category%27%3A+%27service%27%2C+%27pricing_model%27%3A+%27CBP%27%7D%2C+%27recipient_id%27%3A+%272349039756628%27%2C+%27status%27%3A+%27sent%27%2C+%27timestamp%27%3A+%271735424268%27%7D%5D'>

请求后的数据。GET：

{'statuses': "[{'conversation': {'expiration_timestamp': '1735510680', 'id': '57f7d7d4d255f4c7987ac3557bf536e3', 'origin': {'type': 'service'}}, 'id': 'wamid.HBgNMjM0OTAzOTc1NjYyOBUCABEYEjdCMTJFNUZDNzNFQjkxQ0IyRQA=', 'pricing': {'billable': True, 'category': 'service', 'pricing_model': 'CBP'}, 'recipient_id': '2349039756628', 'status': 'sent', 'timestamp': '1735424268'}]"}

这里的问题是列表中的双引号，如“[{'conversation'...

预期结果是：

{'statuses': [{'conversation': {'expiration_timestamp': '1735510680', 'id': '57f7d7d4d255f4c7987ac3557bf536e3', 'origin': {'type': 'service'}}, 'id': 'wamid.HBgNMjM0OTAzOTc1NjYyOBUCABEYEjdCMTJFNUZDNzNFQjkxQ0IyRQA=', 'pricing': {'billable': True, 'category': 'service', 'pricing_model': 'CBP'}, 'recipient_id': '2349039756628', 'status': 'sent', 'timestamp': '1735424268'}]}

这是我的观点：

class StatusesPayloadLayerView(generics.GenericAPIView):
    permission_classes = (permissions.AllowAny,)
    
    def get(self, request, *args, **kwargs):
        payload = request.GET
        data = payload.dict()

从 url 编码参考here来看，编码数据看起来很好，因为列表之前似乎没有双引号，这将是“%22”表示法，所以我不太明白双引号来自哪里来自。

Answer 1

这里的问题是列表中的双引号。

不。这不是字符串的 content 的一部分。这是因为 Python 的 repr(..) 函数 尝试将值打印为 Python 文字表达式，例如

{'a': 'b'}

在

'a'

和

'b'

周围打印单引号，但这些不是 的一部分字符串的内容。

您可以使用 JSON 解码值；

class StatusesPayloadLayerView(generics.GenericAPIView):
    permission_classes = (permissions.AllowAny,)
    
    def get(self, request, *args, **kwargs):
        payload = request.GET
        data = payload.dict()
        print(json.loads(data['statuses']))

这将打印：

[{'conversation': {'expiration_timestamp': '1735510680', 'id': '57f7d7d4d255f4c7987ac3557bf536e3', 'origin': {'type': 'service'}}, 'id': 'wamid.HBgNMjM0OTAzOTc1NjYyOBUCABEYEjdCMTJFNUZDNzNFQjkxQ0IyRQA=', 'pricing': {'billable': True, 'category': 'service', 'pricing_model': 'CBP'}, 'recipient_id': '2349039756628', 'status': 'sent', 'timestamp': '1735424268'}]
