我有一个本地服务器，该服务器的REST API运行在https://localhost:61000上，可以向其发送以下Curl请求：

curl -X POST "https://localhost:61000/users/logout" -H "accept: */*" -H "Locale: en"

它将返回以下响应

在使用WinSock和OpenSSL库的MSVC ++中，我可以从200的端口google.com获取响应代码443，但是当我尝试使用本地主机时在端口61000上，我总是得到一个HTTP/1.1 400 Bad Request

响应：

假设（HTTP）400错误的请求响应状态代码指示服务器由于某些被视为客户端错误的原因而无法或不会处理该请求，但是我不知道如何在以下位置创建该请求正确的方法。
