请教一个HTTPClient问题

njsoftcn 2009-12-09 09:25:23

请教高人，我刚学java网络编程不久，想做一个“人人网”共享程序，但是一直不能成功，想请帮我看看我的程序错在哪里，代码如下：
用的是httpClient 3.1工具包
public class httpLogin {

final String LOGON_SITE = "www.renren.com";
final int LOGON_PORT = 80;
private Calendar calendar;

private HttpClient client;

private String tsc;

public httpLogin() {

client = new HttpClient();
client.getHostConfiguration().setHost(LOGON_SITE, LOGON_PORT, "http");
client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
GetMethod authget = new GetMethod("/");

try {
client.executeMethod(authget);
} catch (IOException ex) {
}
System.out.println("Login form get: " + authget.getStatusLine().toString());
authget.releaseConnection();
CookieSpec cookiespec = CookiePolicy.getDefaultSpec();
Cookie[] initcookies = cookiespec.match(
LOGON_SITE, LOGON_PORT, "/", false, client.getState().getCookies());
System.out.println("Initial set of cookies:");//打印Cookies
if (initcookies.length == 0) {
System.out.println("None");
} else {
for (int i = 0; i < initcookies.length; i++) {
System.out.println("- " + initcookies[i].toString());
}
}

}

public boolean login(){//登录
