在成功更新资源后，我遇到一个JSON解码错误

Question

在更新azure门户上的索引模式之后，我得到了以下信息。

/updateindex/处的JSONDecodeError

模式正在成功更新，但是我得到了这个错误和500个状态代码。

这是我的职责

    url = 'https://search-test.search.windows.net/indexes/hotels-quickstar11t?api-version=2020-06-30'

        ]
    }
        
    headers = {'Content-Type': 'application/json', 'api-key': 'key'}

    response = requests.put(url, headers=headers, json=index_schema)
    index = response.json()

    return HttpResponse(response)

有什么想法吗？

Answer 1

基本上，问题在于您期望从搜索服务返回JSON格式的响应，而在索引更新时，该服务实际上在默认情况下不会返回任何内容。 因此，下面的代码行引发了一个错误:

index = response.json()

如果您想要回JSON响应，您将需要用return=representation设置prefer请求头。 当您这样做时，您应该会看到JSON响应返回。

请更改以下代码行:

headers = {'Content-Type': 'application/json', 'api-key': 'key'}

至

headers = {'Content-Type': 'application/json', 'api-key': 'key', 'Prefer': 'return=representation'}

您应该不会收到此错误。
