python - 成功更新资源后，我收到 JSON 解码错误

Question

在 Azure 门户上更新索引架构后，我收到以下信息。

JSONDecodeError at /updateIndex/

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

@csrf_exempt
def updateIndex(request):
    
    url = 'https://search-test.search.windows.net/indexes/hotels-quickstar11t?api-version=2020-06-30'
    index_schema = {

        "fields": [
            {"name": "HotelId", "type": "Edm.String", "key": "true", "filterable": "true"},
            {"name": "HotelName", "type": "Edm.String", "searchable": "true", "filterable": "false", "sortable": "true", "facetable": "false"},
            {"name": "Description", "type": "Edm.String", "searchable": "true", "filterable": "false", "sortable": "false", "facetable": "false", "analyzer": "en.lucene"},
            {"name": "Description_fr", "type": "Edm.String", "searchable": "true", "filterable": "false", "sortable": "false", "facetable": "false", "analyzer": "fr.lucene"},
            {"name": "Category", "type": "Edm.String", "searchable": "true", "filterable": "true", "sortable": "true", "facetable": "true"},

            {"name": "Address", "type": "Edm.ComplexType", 
                "fields": [
                    {"name": "StreetAddress", "type": "Edm.String", "filterable": "false", "sortable": "false", "facetable": "false", "searchable": "true"},
                    {"name": "City", "type": "Edm.String", "searchable": "true", "filterable": "true", "sortable": "true", "facetable": "true"},

                    {"name": "PostalCode", "type": "Edm.String", "searchable": "true", "filterable": "true", "sortable": "true", "facetable": "true"},
                    {"name": "Country", "type": "Edm.String", "searchable": "true", "filterable": "true", "sortable": "true", "facetable": "true"}
                ]
            },
            {"name": "Price", "type": "Edm.Double", "filterable": "true", "sortable": "true", "facetable": "true"},
            {"name": "Cost", "type": "Edm.Double", "filterable": "true", "sortable": "true", "facetable": "true"},
            {"name": "CostTest", "type": "Edm.Double", "filterable": "true", "sortable": "true", "facetable": "true"}


        ]
    }
        
    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？

基本上，问题在于您期望从搜索服务返回 JSON 格式的响应，而该服务实际上在更新索引时默认情况下不会返回任何内容。因此，以下代码行会引发错误:

index = response.json()

如果您想要返回 JSON 响应，则需要使用 return=representation 设置 Prefer 请求 header 。当您这样做时，您应该会看到 JSON 响应。

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'}

并且您不应该收到此错误。
