Question

在访问网络的时候，有时候需要认证，sdk我看不太明白。在internetsession类中有一个SETOPTION，可使用不好……CInternetSession sess;
char * pwd = "dfgasdfsdf";
char * login_name = "dsfgdsgds";
if(AuthenticationCode ==401) //server authentication
{
int nn =sess.SetOption(INTERNET_OPTION_PROXY_PASSWORD,pwd,sizeof(pwd));
if(!nn) nn = GetLastError();
int mm =sess.SetOption(INTERNET_OPTION_USERNAME,login_name,strlen(login_name)+1,0);
if(!mm) mm = GetLastError();}
返回的值12018错误：
ERROR_WINHTTP_INCORRECT_HANDLE_TYPE (12018)
The type of handle supplied is incorrect for this operation.
