c++ - 无法发送代理凭据 (407)

Question

我正在尝试编写与需要密码和用户名身份验证（ip:port:username:pw）的代理连接的代码 C++ 程序，我得到了 http 工作，但是当我使用 https 时，我总是收到 407 错误。

如何以正确的方式在 https 上发送代理凭据？(C++)

Answer 1

这很好，因为状态 407 意味着代理需要身份验证。

所以你可以使用这个：

    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;
   } 

这决定了身份验证方案......然后你使用

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

我希望这会有所帮助...我也正在使用这些工具从 azure 市场连接到 Microsoft 翻译器，因为它移到了那里，并且从 8 月开始，所有旧的 bing 翻译器都不会收到请求。对我来说，它是通过标头发送身份验证密钥。但我猜你有一个用户名和密码。
