调用第三方接口生成短链接（四）

 

 API文档： http://980.so/。可以参照调用第三方接口生成短链接（二），

用到的Java jar包：

httpclient-4.5.jar,httpclient-cache-4.5.jar,httpclient-win-4.5.jar,httpcore-4.4.1.jar,httpmime-4.5.jar,fastjson-1.2.2.jar。

下载地址：http://download.csdn.net/detail/litter_fisher/9923346。

具体代码如下，点击可查看：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;

public class Test980 {
	
	static String ACTIONURL = "http://980.so/api.php";
	public static void main(String[] args) {		
		String longUrl = "https://www.baidu.com";
		Test980 ts = new Test980();
		System.out.println(ts.getUrlTxt(longUrl));
		System.out.println("--------------");
		System.out.println(ts.getUrlJson(longUrl));		
	}
	
	public String getUrlTxt(String url) {
		String ret = "";
		try {
			String longUrlSuo =  java.net.URLEncoder.encode(url,"utf-8");
			String result = HttpRequest.sendGet(ACTIONURL, "url="+longUrlSuo);
			if(result==null || "".equals(result)){
				return "";
			}		
			System.out.println("--result: --" + result);
			ret = result;
		} catch (Exception e) {
			e.printStackTrace();
		} 
		return ret;	
	}
	
	public String getUrlJson(String url) {
		String ret = "";
		try {
			String longUrlSuo =  java.net.URLEncoder.encode(url,"utf-8");
			String result = HttpRequest.sendGet(ACTIONURL, "url="+longUrlSuo+"&format=json");
			if(result==null || "".equals(result)){
				return "";
			}		
			JSONObject json = JSON.parseObject(result);	
			System.out.println("--result: --" + json.toJSONString());
			ret = json.get("url").toString();
		} catch (Exception e) {
			e.printStackTrace();
		} 
		return ret;	
	}
	


	
}

同样的接口文档还要http://ni2.org/api，代码如下：

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
public class TestNi2 {
	static String ACTIONURL = "http://ni2.org/api/create.json";
	public static void main(String[] args) {
		String  url = "https://www.baidu.com";
		TestNi2 tn = new TestNi2();
		System.out.println(tn.getUrlJson(url));
	}

	public String getUrlJson(String url) {
		String ret = "";
		try {
			String longUrlSuo =  java.net.URLEncoder.encode(url,"utf-8");
			String result = HttpRequest.sendGet(ACTIONURL, "url="+longUrlSuo+"&format=json");
			if(result==null || "".equals(result)){
				return "";
			}		
			JSONObject json = JSON.parseObject(result);	
			System.out.println("--result: --" + json.toJSONString());
			ret = json.get("url").toString();
		} catch (Exception e) {
			e.printStackTrace();
		} 
		return ret;	
	}
}

　　由于http的请求方式经常用到，此处已将其抽离成一个公共类，代码如下： 

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.URL;
import java.net.URLConnection;

public class HttpRequest {
    /**
     * 向指定URL发送GET方法的请求
     * @param url 发送请求的URL
     * @param param 请求参数，请求参数应该是 name1=value1&name2=value2 的形式。
     * @return URL 所代表远程资源的响应结果
     */
    public static String sendGet(String url, String param) {
        String result = "";
        BufferedReader in = null;
        try {
            String urlNameString = url + "?" + param;
            URL realUrl = new URL(urlNameString);
            // 打开和URL之间的连接
            URLConnection connection = realUrl.openConnection();
            // 设置通用的请求属性
            connection.setRequestProperty("accept", "*/*");
            connection.setRequestProperty("connection", "Keep-Alive");
            connection.setRequestProperty("user-agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
            // 建立实际的连接
            connection.connect();
            // 定义 BufferedReader输入流来读取URL的响应
            in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }
        } catch (Exception e) {
            System.out.println("发送GET请求出现异常！" + e);
            e.printStackTrace();
        }
        // 使用finally块来关闭输入流
        finally {
            try {
                if (in != null) {
                    in.close();

            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }
        return result;
    }

    /**

     */
    public static String sendPost(String url, String param) {
        PrintWriter out = null;
        BufferedReader in = null;
        String result = "";
        try {
            URL realUrl = new URL(url);
            // 打开和URL之间的连接

            // flush输出流的缓冲
            out.flush();
            // 定义BufferedReader输入流来读取URL的响应
            in = new BufferedReader(
                    new InputStreamReader(conn.getInputStream()));
