用wininet实现http basic认证
今日需要做个在线升级的小工具，服务器为svn服务器，需要输密码，差了下http相关资料整理如下，以备后面需要：
HINTERNET hOpenHandle,, hConnectHandle hResourceHandle; //分别为初始化,连
接及资源句柄
DWORD dwStatus;
DWORD dwStatusSize = sizeof(dwStatus);
char strUsername[64] = "zjh", strPassword[64]="xxx"; //用户名及密码,可以通
过其他如交互方式等获取
hOpenHandle = InternetOpen(TEXT("ZAgent"),
INTERNET_OPEN_TYPE_PRECONFIG,
NULL, NULL, 0);
hConnectHandle = InternetConnect(hOpenHandle,
TEXT("10.xx.xx.xx"),
INTERNET_INVALID_PORT_NUMBER,
NULL,
NULL,
INTERNET_SERVICE_HTTP,
0,0);
hResourceHandle = HttpOpenRequest(hConnectHandle, TEXT("GET"),
TEXT("/svn/......."), //路径
NULL, NULL, NULL,
INTERNET_FLAG_KEEP_CONNECTION,
0);
DWORD cchUserLength = strlen(strUsername), cchPasswordLength = strlen(
strPassword);
BOOL bConnectOK = FALSE;
while (1)
{
HttpSendRequest(hResourceHandle, NULL, 0, NULL, 0);//发送请求
HttpQueryInfo(hResourceHandle, HTTP_QUERY_FLAG_NUMBER | //处理服务
器的返回信息,得到状态错误码
HTTP_QUERY_STATUS_CODE, &dwStatus, &dwStatusSize, NULL);
if (HTTP_STATUS_PROXY_AUTH_REQ == dwStatus)
{
InternetSetOption(hResourceHandle, INTERNET_OPTION_PROXY_USERNAME,
strUsername,
cchUserLength+1);
InternetSetOption(hResourceHandle, INTERNET_OPTION_PROXY_PASSWORD,
strPassword,
cchPasswordLength+1);
continue;
}
else if(HTTP_STATUS_DENIED == dwStatus) //设置用户名密码
,这个也可以在前面直接设置,如果充分信任没被钓鱼的话
{
InternetSetOption(hResourceHandle, INTERNET_OPTION_USERNAME,
strUsername, cchUserLength+1);
InternetSetOption(hResourceHandle, INTERNET_OPTION_PASSWORD,
strPassword, cchPasswordLength+1); //这里如果密码一致错
误就死循环了,可以sleep一会并且可设定次数,达到失败次数也break且没有设置bConnect
OK.
continue;
}
bConnectOK = TRUE; //如果密码正确或不需要认证就到这里了
break;
}
if(bConnectOK )
{
// InternetReadFile 读数据
}
