HttpClient GET請求小實例,先簡單記錄下。

package com.httpclientget;

import java.io.IOException;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
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
{
	HttpClient client = HttpClients.createDefault();
	
	@Override
	public void run() {

		String urlStr = "https://openapi.youdao.com/api?q=teacher&salt=1495119694612&sign=CB78BFCEA15C3AB13A1BB015EFCBDF0A&from=en&appKey=7743eee7f7e11d75&to=zh-CHS";
		HttpGet get = new HttpGet(urlStr);
		try {
			
			HttpResponse response = client.execute(get);
			HttpEntity entity = response.getEntity();
			String result = EntityUtils.toString(entity, "UTF-8");
			System.out.print(result);;
			
		} catch (ClientProtocolException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

運行結果:
