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; } /** * 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; } }
