}

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");
}
