由于接收到400错误且没有主机URI，我在连接时遇到问题。起初我没有使用它的原因是因为Postman没有使用它，但是他们的API调用成功了。有人知道主机URI是否必要吗？如果有，我可以在Microsoft Azure中的何处找到它？专门针对媒体服务。在Http 1.1中，主机头是必需的 Http的要点：
HTTP/1.0 does not bring host, and HTTP/1.1 adds host head.
Host can be a domain name, or IP, or port number.
Host can be customized by programs. Some programs can define false host in order to prevent operators or bypass firewalls.
Host in HTTP/1.1 can be null value but not without. If no host head is taken, 400 Bad request will be returned.
The HTTP response header does not contain the host field.
Some sites do not check host and can pass arbitrary values.
在您的情况下，我们可以用
