我正在尝试使用需要密码和用户名验证的代理连接的代码C ++程序(ip:port:username:pw)我的http工作正常,但是当我使用https时,我总是得到407错误。

如何以正确的方式在https上发送代理凭据? (C ++)

这很好,因为状态407意味着代理需要身份验证。

所以你可以使用它:

    case 407:
            // The proxy requires authentication.
            printf( "The proxy requires authentication.  Sending credentials...\n" );

            // Obtain the supported and preferred schemes.
            bResults = WinHttpQueryAuthSchemes( hRequest, 
                &dwSupportedSchemes, 
                &dwFirstScheme, 
                &dwTarget );

            // Set the credentials before resending the request.
            if( bResults )
                dwProxyAuthScheme = ChooseAuthScheme(dwSupportedSchemes);

            // If the same credentials are requested twice, abort the
            // request.  For simplicity, this sample does not check 
            // for a repeated sequence of status codes.
            if( dwLastStatus == 407 )
                bDone = TRUE;
            break;

功能

    DWORD ChooseAuthScheme( DWORD dwSupportedSchemes )
  {
//  It is the server's responsibility only to accept 
//  authentication schemes that provide a sufficient
//  level of security to protect the servers resources.
//
//  The client is also obligated only to use an authentication
//  scheme that adequately protects its username and password.
//
//  Thus, this sample code does not use Basic authentication  
//  becaus Basic authentication exposes the client's username
//  and password to anyone monitoring the connection.

if( dwSupportedSchemes & WINHTTP_AUTH_SCHEME_NEGOTIATE )
    return WINHTTP_AUTH_SCHEME_NEGOTIATE;
else if( dwSupportedSchemes & WINHTTP_AUTH_SCHEME_NTLM )
    return WINHTTP_AUTH_SCHEME_NTLM;
else if( dwSupportedSchemes & WINHTTP_AUTH_SCHEME_PASSPORT )
    return WINHTTP_AUTH_SCHEME_PASSPORT;
else if( dwSupportedSchemes & WINHTTP_AUTH_SCHEME_DIGEST )
    return WINHTTP_AUTH_SCHEME_DIGEST;
else
    return 0;
   } 

这确定了身份验证方案.....然后使用

    bResults = WinHttpSetCredentials( hRequest, 
        WINHTTP_AUTH_TARGET_SERVER, 
        dwProxyAuthScheme,
        username,
        password,
        NULL );

我希望这有帮助...我也正在使用这些连接到azure市场的微软翻译器,因为它移动到那里,从八月开始,所有旧的翻译都不会得到请求。对我来说,它是通过标头发送身份验证密钥。但我想你有一个用户名和密码。
