 GET示例

package com.httpdemo.auto;

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class DoGetde {
    public static void main(String[] args) throws ClientProtocolException, IOException {
        String url = "http://apis.juhe.cn/fapig/zodiac/query";
        url += "?keyword=兔&key=6d43e98f74c283db936d0e3b742ebde0";
        CloseableHttpClient httpClients = HttpClients.createDefault();
        HttpGet get = new HttpGet(url);
        HttpResponse httpResponse = httpClients.execute(get);
        String result = EntityUtils.toString(httpResponse.getEntity());
        System.out.println(result);

    }

}

三、通过json对象传输的例子

 

 

 

 

 

 

package com.httpdemo.auto;

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class Jsonpostdemo {
    public static void main(String[] args) throws ClientProtocolException, IOException {
        String url = "http://xxx.xxx/api/v1/transdata";
        HttpPost post = new HttpPost(url);
        post.setHeader("x-sign", "");
        post.setHeader("Cookie",
        String jsonstr = "{\"appKey\": \"XSpace\",\"timeout\": 20000,\"v\": \"1.0\",\"api\": \"mopen.ssd.openme.ssd.bot.list.page\",\"data\": {\"pageNo\": 1\"pageSize\": 5},\"type\": \"GET\"}}";
        StringEntity stringEntity = new StringEntity(jsonstr);
        post.setEntity(stringEntity);
        HttpClient hClient = HttpClients.createDefault();
        HttpResponse httpResponse = hClient.execute(post);
        String result = EntityUtils.toString(httpResponse.getEntity());
        System.out.println(result);

    }
}
