Answer 1

送你个demo：

package org.kodejava.example.commons.httpclient;

import org.apache.commons.httpclient.Credentials;
import org.apache.commons.httpclient.HostConfiguration;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.UsernamePasswordCredentials;
import org.apache.commons.httpclient.auth.AuthScope;
import org.apache.commons.httpclient.methods.GetMethod;

import java.io.IOException;

public class HttpGetProxy {
private static final String PROXY_HOST = "proxy.host.com";
private static final int PROXY_PORT = 8080;

public static void main(String[] args) {
HttpClient client = new HttpClient();
HttpMethod method = new GetMethod("http://www.kodejava.org");

HostConfiguration config = client.getHostConfiguration();
config.setProxy(PROXY_HOST, PROXY_PORT);

String username = "guest";
String password = "s3cr3t";
Credentials credentials = new UsernamePasswordCredentials(username, password);
AuthScope authScope = new AuthScope(PROXY_HOST, PROXY_PORT);

client.getState().setProxyCredentials(authScope, credentials);

try {
client.executeMethod(method);

if (method.getStatusCode() == HttpStatus.SC_OK) {
String response = method.getResponseBodyAsString();
System.out.println("Response = " + response);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
method.releaseConnection();
}
}
}
