在 azure 门户上更新索引架构后，我得到以下信息。

/updateIndex/ 处的 JSONDecodeError

架构已成功更新，但我收到此错误以及 500 状态代码。

这是我的功能

    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？

【解决方案1】：

基本上，问题在于您希望搜索服务返回 JSON 格式的响应，而默认情况下，更新索引时服务实际上不会返回任何内容。因此以下代码行抛出错误：

index = response.json()

如果您想要返回 JSON 响应，您需要将 Prefer 请求标头设置为 return=representation。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'}

到

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

你不应该得到这个错误。
