调用方式:

String ss = "[" ;

String date = new java.text.SimpleDateFormat("yyyyMMddHHmmss").format(new java.util.Date());

Gps gps= PositionUtil.gcj_To_Gps84(Double.valueOf(split[1]), Double.valueOf(split[0]));//转化为84的坐标系

Gps gps1= PositionUtil.gcj_To_Gps84(Double.valueOf(split02[1]), Double.valueOf(split02[0]));//转化为84的坐标系

Gps gps2= PositionUtil.gcj_To_Gps84(Double.valueOf(split03[1]), Double.valueOf(split03[0]));//转化为84的坐标系

ss+="{\"time\":\""+date+"\",\"lon\":"+gps.getWgLon()+",\"lat\":"+gps.getWgLat()+",\"speed\":20,\"direc\":0},";

ss+="{\"time\":\""+date+"\",\"lon\":"+gps1.getWgLon()+",\"lat\":"+gps1.getWgLat()+",\"speed\":30,\"direc\":0},";

ss+="{\"time\":\""+date+"\",\"lon\":"+gps2.getWgLon()+",\"lat\":"+gps2.getWgLat()+",\"speed\":30,\"direc\":0}";

ss+="]";

String param=getHttpURLConnection(uriAPI+"/RouteTrafficInfoSearch?bizcode=fBAym29ZX11kVKbuQVnJ",ss);

System.out.println(param);

返回xml格式的数据

out.flush();

out.close();

DataInputStream in = new DataInputStream(connection.getInputStream());

int len = in.available();

byte[] b = new byte[len];

in.read(b);

// System.out.println(new String(b,"utf-8"));

return new String(b,"utf-8");
