你好

我确实发现你只是在发送请求标头中的Ocp-Apim-Subscription-Key。除此之外，必须将以下（用户代理，客户端IP，客户端ID，主机）作为请求标头的一部分发送。

I do observe that you are sending only Ocp-Apim-Subscription-Key in the request header. In addition to that, the following ones (user-agent, client ip, client id, host) have to be sent as part of the request header.

User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows Phone 8.0; Trident/6.0; IEMobile/10.0; ARM; Touch; NOKIA; Lumia 822)
X-Search-ClientIP: 999.999.999.999
X-MSEdge-ClientID: <blobFromPriorResponseGoesHere>
Host: api.cognitive.microsoft.com
