Question

我真的需要你的帮助。我必须在我的大学制作一个课程。它必须登录需要HTTP协议的学术系统。我正在使用HTTP Service Apaches的类，但是显示了错误的输出。

我已经安装了HTTPFox，并且我发现了要放在类 BasicNameValuePair上的属性

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

public class NavegadorSite {

    public void x () {

        final HttpClient client = new DefaultHttpClient();
        final HttpPost post = new HttpPost(
                "https://www.sigaa.ufs.br/sigaa/logar.do?dispatch=logOn");
        try {
            final List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
            nameValuePairs.add(new BasicNameValuePair("width", "1140"));
            nameValuePairs.add(new BasicNameValuePair("height", "900"));
            nameValuePairs.add(new BasicNameValuePair("urlRedirect", ""));
            nameValuePairs.add(new BasicNameValuePair("acao", ""));
            nameValuePairs.add(new BasicNameValuePair("acessibilidade", ""));
            nameValuePairs.add(new BasicNameValuePair("user.login", "unknown"));
            nameValuePairs.add(new BasicNameValuePair("user.senha", ""));

            post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            final HttpResponse response = client.execute(post);
            final BufferedReader rd = new BufferedReader(new InputStreamReader(
                    response.getEntity().getContent()));
            String line = "";
            while ((line = rd.readLine()) != null) {
                System.out.println(line);
            }
        } catch (final IOException e) {
            e.printStackTrace();
        }
    }

    public static void main (String[] args) {

        NavegadorSite ns = new NavegadorSite();
        ns.x();
    }
}

这是输出：

更多一个问题：这样做是违法的吗？我从一个受版权保护的网站上获取信息。

谢谢！

您可能需要提供证书或将其CA导入您的信任存储区。如果它只是一个测试宠物项目，您可以将insecure设置为您的http客户端选项。
