调用第三方接口生成短链接(二)

方法总是多样的,现在介绍另一种生成短链接的方式:

网址缩短API文档: http://suo.im/。

接下来提供两种调用方式生成短链接:①TXT格式短网址API接口,②JSON格式短网址API接口。

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。

实验代码如下:

package space;
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 TestSuo {
	
	static String ACTIONURL = "http://suo.im/api.php";
	
	public static void main(String[] args) {
		
		String longUrl = "https://www.baidu.com";
		TestSuo ts = new TestSuo();
		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 = 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 = 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;	
	}
