## 前言 ##

需要说明的是，这里使用的是微博提供的接口，也就是说，这个短链接是微博给我们提供的

在网络上到一个我们工具站

### 言归正传 ###

[微博开发平台APIhttp://open.weibo.com/wiki/2/short\_url/shorten][APIhttp_open.weibo.com_wiki_2_short_url_shorten]

### 1、调用接口(主要部分) ###

public  static String  LongToShortLink (String longUrl) { 
    
            String requestUrl = "http://api.weibo.com/2/short_url/shorten.json?source=2849184197&url_long=urlLongParam";
            requestUrl = requestUrl.replace("urlLongParam", longUrl);
            String body = HttpHelper.handleGet(requestUrl);
            if(body.contains("false")){ 
                log.error(body);
            }
            return body;
        }

### 2、Http请求类 ###

import lombok.extern.slf4j.Slf4j;
    import org.apache.commons.io.IOUtils;
    import org.apache.http.HttpResponse;
    import org.apache.http.client.config.RequestConfig;
    import org.apache.http.client.methods.HttpGet;
    import org.apache.http.impl.client.CloseableHttpClient;
    import org.apache.http.impl.client.HttpClients;
    
    @Slf4j
    public class HttpHelper { 
    
    
        public static final String ENCODING_UTF8 = "UTF-8";
        public static final int OVERTIME = 2000;
    
        private static RequestConfig defaultRequestConfig(Integer over_time) { 
            if (over_time == null) { 
                return RequestConfig.custom().setSocketTimeout(OVERTIME).setConnectTimeout(OVERTIME).setConnectionRequestTimeout(OVERTIME).build();
            } else { 
                return RequestConfig.custom().setSocketTimeout(over_time).setConnectTimeout(over_time).setConnectionRequestTimeout(over_time).build();
            }
        }
    
    
        /** * http 普通get请求 * * @param uri * @return */
        public static String handleGet(String uri) { 
            CloseableHttpClient httpclient = HttpClients.custom().build();
            HttpGet request = null;
            HttpResponse response = null;
            String result = null ;
            try { 
                request = new HttpGet(uri);
                request.setConfig(defaultRequestConfig(null));
                response = httpclient.execute(request);
                result = IOUtils.toString(response.getEntity().getContent(), ENCODING_UTF8);
            } catch (Exception e) { 
                log.error(e.getMessage(), e);
            } finally { 
                IOUtils.closeQuietly(httpclient);
            }
            return result;
    
        }
    
    }

### 3、main方法调用 ###

import com.hlj.linktoshort.data.ShortLinkResult;
    import com.hlj.linktoshort.utils.JsonUtils;
    import com.hlj.linktoshort.utils.LinkUtils;
    import com.hlj.linktoshort.utils.QrCodeUtils;
    import lombok.extern.slf4j.Slf4j;
    
    import javax.imageio.ImageIO;
    import java.awt.image.BufferedImage;
    import java.io.File;
    import java.io.IOException;
    
    /** * 类描述： 长连接转短链接 * * http://api.weibo.com/2/short_url/shorten.json?source=2849184197&url_long=http://www.cnblogs.com */
    @Slf4j
    public class StartMain { 
    
    
        public static void main(String[] args) { 
    
            String longUrl = "" +
                    "https://blog.csdn.net/u012954706"
                    ;
    
            String sourceName = "origin.jpeg" ;
    
    
    
    
            String sourceFilePath = "/Users/healerjean/Desktop/"+sourceName;
            String saveFilePath = "/Users/healerjean/Desktop/A"+sourceName+".png";
    
            String shortLink =  LinkUtils.LongToShortLink(longUrl);
            ShortLinkResult shortLinkResult = JsonUtils.toObject(shortLink,ShortLinkResult.class );
            log.info("\n短链接:"+shortLinkResult.getUrls().get(0).getUrl_short()+"\n长链接:"+shortLinkResult.getUrls().get(0).getUrl_long());
        }

### 4、实体类 ###

package com.hlj.linktoshort.data;
    
    import java.util.List;
    
    /** * 作者 ：HealerJean * 日期 ：2018/11/23 上午11:37. * 类描述： */
    public class ShortLinkResult { 
    
        private List<UrlsBean> urls;
    
        public List<UrlsBean> getUrls() { 
            return urls;
        }
    
        public void setUrls(List<UrlsBean> urls) { 
            this.urls = urls;
        }
    
        public static class UrlsBean { 
            /** * result : true * url_short : http://t.cn/h5FGy * url_long : http://www.cnblogs.com * object_type : * type : 0 * object_id : */
    
            private boolean result;
            private String url_short;
            private String url_long;
            private String object_type;
            private int type;
            private String object_id;
    
            public boolean isResult() { 
                return result;
            }
    
            public void setResult(boolean result) { 
                this.result = result;
            }
    
            public String getUrl_short() { 
                return url_short;
            }
    
            public void setUrl_short(String url_short) { 
                this.url_short = url_short;
            }
    
            public String getUrl_long() { 
                return url_long;
            }
    
            public void setUrl_long(String url_long) { 
                this.url_long = url_long;
            }
    
            public String getObject_type() { 
                return object_type;
            }
    
            public void setObject_type(String object_type) { 
                this.object_type = object_type;
            }
    
            public int getType() { 
                return type;
            }
    
            public void setType(int type) { 
                this.type = type;
            }
    
            public String getObject_id() { 
                return object_id;
            }
    
            public void setObject_id(String object_id) { 
                this.object_id = object_id;
            }
        }
    }
