如查詢北京市東城區長安街的郵編，可以通過以下地址查詢

http://cpdc.chinapost.com.cn/web/index.php?m=postsearch&c=index&a=ajax_addr&searchkey=北京市東城區長安街

返回json串格式化后為，rs對應的數組為該地址對應的郵編，可以按需求選取

{"su": true, "errcode": 0, "rs": [{"ADDR": "北京市密云縣長安街0", "POSTCODE": "101599"}, {"ADDR": "北京市密云縣長安街10號", "POSTCODE": "101599"}, {"ADDR": "北京市密云縣長安街11號", "POSTCODE": "101599"}], "pageinfo": {"CURRENTPAGE": "1", "TOTALPAGE": "1", "ITEMCOUNT": 3}, "searchkey": "北京市東城區長安街", "checkcode": true, "now_num": 3, "pageshtml": "" }

當查詢的地址不存在時，如隨便輸入的字母串adsaffgrjdg

http://cpdc.chinapost.com.cn/web/index.php?m=postsearch&c=index&a=ajax_addr&searchkey=adsaffgrjdg

返回體如下，此時rs對應數組為空數組

{"su": true, "errcode": 0, "rs": [ ], "pageinfo": {"CURRENTPAGE": "0", "TOTALPAGE": "0", "ITEMCOUNT": 0}, "searchkey": "adsaffgrjdg", "checkcode": true, "now_num": 0, "pageshtml": "" }

調用接口方式網上一搜一大堆，這里只寫個供參考，傳入參數為拼接后的 地址即可

public static String getConnection(String path) throws Exception{URL url = new URL(path);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.connect();BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(),"UTF-8"));String line ;StringBuilder sb = new StringBuilder();while((line=reader.readLine())!=null){sb.append(line);}connection.disconnect();return sb.toString();}
