问题描述
IWinHttpRequest接口正常工作，直到TLS版本从服务器端更改为止。服务器的TLS版本已更改为TLSv1.1及更高版本。
由于此更改，我无法从服务器获得任何响应。
所以我决定使用WinHttpSetOption来设置协议版本。但它不起作用。
请有人帮帮我吗？
我是什么尝试过：
IWinHttpRequest接口工作正常，直到从服务器端更改TLS版本。服务器的TLS版本已更改为TLSv1.1及更高版本。
由于此更改，我无法从服务器获得任何响应。
所以我决定使用WinHttpSetOption来设置协议版本。但它不起作用。
以下代码是我设置选项的地方。
IWinHttpRequest interface was working fine until TLS version has been changed from Server side. TLS version of server has been changed to TLSv1.1 and higher.
because of this change I am not able to get any response from server.
So I decided to use WinHttpSetOption to set protocol version. but it doesn't work.
Please anybody can help me?
What I have tried:
IWinHttpRequest interface was working fine until TLS version has been changed from Server side. TLS version of server has been changed to TLSv1.1 and higher.
because of this change I am not able to get any response from server.
So I decided to use WinHttpSetOption to set protocol version. but it doesn't work.
The below code is where I set the options.
dwVal = WINHTTP_FLAG_SECURE_PROTOCOL_TLS1_1 | WINHTTP_FLAG_SECURE_PROTOCOL_TLS1_2;
bRet = WinHttpSetOption(request_,WINHTTP_OPTION_SECURE_PROTOCOLS,&dwVal,sizeof(dwVal));
if(!bRet)
{
TRACE("error - " , GetLastError());
break;
}
上面的代码不会产生任何错误代码，尽管返回代码为setoption为零。
The above code doers not yield any error code although the return code for setoption is zero.
