Sending a post request to localhost
I need to send an HTTP request from my Android device to a web server that is running on my localhost: 8080 and hosted by Google engine.
current code:
try {
HttpPost httppost = new HttpPost("http://192.168.2.220:8080");
httppost.setHeader("Content-type", "application/json");
ResponseHandler <String> responseHandler = new BasicResponseHandler();
StringEntity se = new StringEntity(object.toString());
se.setContentEncoding(newBasicHeader(HTTP.CONTENT_TYPE,"application/json"));
httppost.setEntity(se);
System.out.println("Request Sent");
String response = httpclient.execute(httppost, responseHandler);
String temp = EntityUtils.toString(response.getEntity());
} catch (ClientProtocolException e) {}
catch (IOException e) {
}
}
I also tried to install:
HttpPost httppost = new HttpPost("http://10.0.2.2:8080");
In all cases, the answer is zero, and the software force is closed. Am I sending the request correctly? can anyone guide me here?
thank

"Send request to localhost" means to send it to the local computer. In your case, this will be an Android device. You want to send a request to your desktop computer, which is the remote host. The problem is that appengine dev_sever by default only binds to the local address, so it cannot be retrieved remotely (i.e. from your Android device). You need to pass a parameter --address
to make it available externally. Check the IP address of the computer and pass it as an address. Something like:
dev_appserver.cmd --address=192.168.2.220
