我有一个简单的REST Web服务,我在我的Android客户端调用。但服务没有解雇。 mu代码有什么问题?请帮帮我!
---------------------------我调用Web服务的方法------------ < / p>
private static void getSelectedCoordinates() {
Log.d("getrespond()", "service calling");
String block_coordinates = Store_Identified_Block.GetBlock();
//Wireless port
// String url ="http://192.168.43.73:84/NewPS/MobileService.svc/GetSelectedCoordinates?input=285,27-524,77";
//Local Host
String url ="http://10.0.2.2:4266/NewPS/MobileService.svc/GetSelectedCoordinates?input=285,27-524,77";
RestClient client = new RestClient(url);
try{
client.Execute(RestClient.RequestMethod.GET);
}
catch (Exception e) {
String error = String.valueOf(e);
Log.d("**********client.Execute(RequestMethod.GET);***********",error);
}
try {
if(client.getResponseCode() == 200) {
Log.d("Response is 200", String.valueOf(client.getResponse()));
result = String.valueOf(client.getResponse());
//Toast.makeText(ctx, "Responce is "+String.valueOf(client.getResponseCode()), 2000).show();
}
else {
String error = String.valueOf(client.getResponse());
Log.d("Response*********** not 200 ************", String.valueOf(client.getResponse()));
}
}catch (Exception e) {
e.printStackTrace();
Log.d("EXCEPTIONI IS 3", e.toString());
// TODO: handle exception
}
}
