itmale 2019-12-02
1.项目结构
导入jar包
jar包去官网下载
解压后项目新建lib目录,将解压包中的lib目录中的zip拷入项目lib目录文件夹,然后build path-->配置到项目中
2.TestGet.java
package testhttpclient;
import java.io.IOException;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
/**

*/
public class TestGet {
public static void main(String[] args) {
new Get().start();
}
}
class Get extends Thread{
//创建标准的httpClient
HttpClient client=HttpClients.createDefault();
@Override
public void run() {
HttpGet get=new HttpGet("http://www.baidu.com");
try {
//执行
HttpResponse response=client.execute(get);
//http实例化对象
HttpEntity entity=response.getEntity();
String result=EntityUtils.toString(entity, "UTF-8");
System.out.println(result);
} catch (IOException e) {
e.printStackTrace();
}
}
}
3.项目运行结果
新建test.xml,拷贝console内容如下:
