楼主,怎么区分SOCK4/SOCK5代理?
SOCK5代理一般还需要身份认证的.
我分很多,多给你分.

能说详细一点吗?

[huang_yi_cn]

The following example code shows how authentication could be handled using InternetSetOption.


HINTERNET hOpenHandle, hResourceHandle;
DWORD dwError, dwStatus;
DWORD dwStatusSize = sizeof(dwStatus);
char strUsername[64], strPassword[64];

hOpenHandle = InternetOpen("Example",
INTERNET_OPEN_TYPE_PRECONFIG,
NULL, NULL, 0);
hConnectHandle = InternetConnect(hOpenHandle,
"www.server.com",
INTERNET_INVALID_PORT_NUMBER,
NULL,
NULL,
INTERNET_SERVICE_HTTP,
0,0);

hResourceHandle = HttpOpenRequest(hConnectHandle, "GET",
"/premium/default.htm",
NULL, NULL, NULL,
INTERNET_FLAG_KEEP_CONNECTION,
0);

resend:

HttpSendRequest(hResourceHandle, NULL, 0, NULL, 0);

HttpQueryInfo(hResourceHandle, HTTP_QUERY_FLAG_NUMBER |
HTTP_QUERY_STATUS_CODE, &dwStatus, &dwStatusSize, NULL);

switch (dwStatus)
{
case HTTP_STATUS_PROXY_AUTH_REQ: // Proxy Authentication Required
// Insert code to set strUsername and strPassword.

// cchUserLength is the length of strUsername and
// cchPasswordLength is the length of strPassword.
DWORD cchUserLength, cchPasswordLength;

// Insert code to safely determine cchUserLength and
// cchPasswordLength. Insert appropriate error handling code.
InternetSetOption(hResourceHandle,
INTERNET_OPTION_PROXY_USERNAME,
strUsername,
cchUserLength+1);

InternetSetOption(hResourceHandle,
INTERNET_OPTION_PROXY_PASSWORD,
strPassword,
cchPasswordLength+1);
goto resend;
break;

case HTTP_STATUS_DENIED: // Server Authentication Required.
// Insert code to set strUsername and strPassword.

// cchUserLength is the length of strUsername and
// cchPasswordLength is the length of strPassword.
DWORD cchUserLength, cchPasswordLength;

// Insert code to safely determine cchUserLength and
// cchPasswordLength. Insert error handling code as
// appropriate.
InternetSetOption(hResourceHandle, INTERNET_OPTION_USERNAME,
strUsername, cchUserLength+1);
InternetSetOption(hResourceHandle, INTERNET_OPTION_PASSWORD,
strPassword, cchPasswordLength+1);
goto resend;
break;
}

// Insert code to read the data from the hResourceHandle
// at this point.



给分, 哈哈

这段代码好象跟代理没什么关系呀!

[huang_yi_cn]

这段代码就是设置代理的用户名和密码的呀, 其中INTERNET_OPTION_USERNAME设置代理服务器的用户名, INTERNET_OPTION_PASSWORD设置相应的密码.
删繁就简, 如果只是纯粹的设置用户名和密码, 只需要下面的代码就可以了.
InternetSetOption(hResourceHandle, INTERNET_OPTION_USERNAME,
strUsername, cchUserLength+1);
InternetSetOption(hResourceHandle, INTERNET_OPTION_PASSWORD,
strPassword, cchPasswordLength+1);

其中strUsername设置用户名, strPassword指定密码.

别忘了给分哟, 呵呵呵

我找到答案了, 来此跟大家分享一下吧:
1. 相关函数:
HINTERNET WINAPI InternetOpen(
LPCTSTR lpszAgent,
DWORD dwAccessType,
LPCTSTR lpszProxy,
LPCTSTR lpszProxyBypass,
DWORD dwFlags);

BOOL WINAPI InternetSetOption(
HINTERNET hInternet,
DWORD dwOption,
LPVOID lpBuffer,
DWORD dwBufferLength);

2. 相关结构
typedef struct {
DWORD dwAccessType;
LPCTSTR lpszProxy;
LPCTSTR lpszProxyBypass;
} INTERNET_PROXY_INFO, *LPINTERNET_PROXY_INFO;

3. 使用代理服务器
(1)请将dwAccessType设置成INTERNET_OPEN_TYPE_PROXY
(2)设置lpszProxy
(a)代理的格式必须为:[<protocol>=][<scheme>://]<proxy>[:<port>].
(b)其中protocol, scheme://, :port是可选项, 如果忽略这三者, 则它们默认分别为
HTTP, HTTP://, :80. 即默认为HTTP代理.
(c)多个代理必须使用" "(空格)隔开
(d)各种常用代理的使用见如下:
HTTP:
HTTP=HTTP://proxyserver:port
FTP:
FTP:FTP://proxyserver:port
GOPHER
GOPHER=HTTP://proxyserver:port
SOCKS=proxyserver:port
其中前三种都可以在msdn中找到, 但第四种我可是找了N多地方才好不容易找到了. 另外要注意, msdn中明确说明只有安装了IE才能使用SOCKS代理.
