I have a server with SSL certificate.
And I am using functions uploadFileHttps(...) to upload an image and get corresponding response with HttpsUrlConnection.
For the upload part, it sent out the image data through output stream.
However, server haven't received that image. Also, when it is trying to obtain response from server through input stream.
It catches an exception "java.net.SocketTimeoutException: Read timed out"
How could I fix it?
private static final int CONNECTION_TIMEOUT = 20000;
private static final int IMAGE_UPLOAD_TIMEOUT = 60000;
private void uploadFileHttps(File file, String requestURL) {
HttpsURLConnection connection = null;
try {
//requestURL is a https link like: https://test.abcde.com/upload
connection = (HttpsURLConnection) new URL(requestURL).openConnection();
connection.setHostnameVerifier(new NullHostNameVerifier());
connection.setConnectTimeout(CONNECTION_TIMEOUT);//timeout for handshake
connection.setReadTimeout(IMAGE_UPLOAD_TIMEOUT);//timeout for waiting read data
connection.setRequestMethod("PUT");
connection.setRequestProperty("Content-Type", "image/jpeg");
Token.setAuthTokenHeader(connection, context);
connection.setDoOutput(true);//set to use httpURLConnection for output
connection.connect();
//upload file to server
DataOutputStream out = new DataOutputStream(connection.getOutputStream());
int bytesRead;
byte buf[] = new byte[1024];
BufferedInputStream bufInput = new BufferedInputStream(new FileInputStream(file));
while ((bytesRead = bufInput.read(buf)) != -1) {
// write output
out.write(buf, 0, bytesRead);
out.flush();
}
out.flush();
out.close();
//get response from server
BufferedReader br = new BufferedReader(new InputStreamReader((connection.getInputStream())));
StringBuilder sb = new StringBuilder();
String output;
while ((output = br.readLine()) != null) {
sb.append(output);
}
System.out.println(sb.toString());
} catch (Exception e) {
if (e != null)
e.printStackTrace();
} finally {
if (connection != null) connection.disconnect();
}
}
class NullHostNameVerifier implements HostnameVerifier {
#Override
public boolean verify(String hostname, SSLSession session) {
Log.i("RestUtilImpl", "Approving certificate for " + hostname);
return true;
}
}

This sets the request method to PUT.
connection.setDoOutput(true);//set to use httpURLConnection for output
This sets the request method to POST. You need to execute this before the PUT line above.

A request method is POST 100%.
I create a new connection so:
URL url = new URL(urlStr);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
Write arguments so:
OutputStream os = connection.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
final String body = builder.toString();
writer.write(body);
writer.flush();
writer.close();
os.close();
What could be the problem?
Please guide me to find the problem in this code, when i use url with HTTP then it works fine but with HTTPS it's giving problem.I have googled but couldn't find a solution. It would be appreciable if someone guide me to save my time Thanks

For https url connection to work in android, use HttpsUrlConnection instead of HttpUrlConnection.
See Documentation here
refer link, it will help as HttpsUrlConnection is required instead of HttpUrlConnection.
http://developer.android.com/reference/javax/net/ssl/HttpsURLConnection.html
http://www.java-samples.com/java/POST-toHTTPS-url-free-java-sample-program.htm
I have implemented HttpUrlConnection to send a request to a local http server (common LAN,Wifi,WifiAP). The code works perfectly fine for normal web servers (www.xyz.com), but fails to do so for local servers (192.168.x.y:z).
The code:
1) The function which makes the request
public static String getDef(String urlInput) {
URL url = null;
try {
url = new URL("http://" + urlInput);
Log.d("http", "calling " + url.toString());
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("Connection", "close");
conn.setRequestMethod("GET");
conn.setDoInput(true);
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.connect();
InputStream in = null;
in = (conn.getInputStream());
String response =readIt(in,5) ;
//response = org.apache.commons.io.IOUtils.toString(in, "UTF-8");
return response;
} catch (IOException e) {
Log.e("http","Error");
e.printStackTrace();
}
return "LocalClient didnt work";
}
2) The function which calls the above function.
new AsyncTask<String, Void, String>(){
#Override
protected String doInBackground(String... params){
try {
return LocalClient.getDef(URL);
} catch (Exception e){
e.printStackTrace();
}
return "Didnt work";
}
#Override
protected void onPostExecute(String string) {
message.append(string);
}
}.execute();
3)The request is received at the server with the following headers.
GET / HTTP/1.1
Connection: close
User-Agent: Dalvik/2.1.0 (Linux; U; Android 5.1.1; Nexus 5 Build/LYZ28E)
Host: 192.168.0.101
Accept-Encoding: gzip
It would be wonderful if someone could point me in the right direction.
I have also tried OkHttp,
public static String get(String url) throws IOException {
OkHttpClient client = new OkHttpClient();
try {
Request request = new Request.Builder()
.url(url)
.build();
Response response = client.newCall(request).execute();
resp= response.body().string();
} catch (IOException e) {
e.printStackTrace();
}
return resp;
}
On using a normal webserver the response is properly returned (source) but while using a local server I get the following error
java.io.EOFException

The problem was server-side and was resolved by using appropriate headers.
OkHttp still doesn't seem to work and the function "public static String getDef(String urlInput)" mentioned above works flawlessly.
It seems there's an open bug about this issue:
https://github.com/square/okhttp/issues/1518
They suggest adding android:vmSafeMode="true" to the manifest file.
I am stuck at this problem. The user inputs their website. It is either http or https, but when they input a https website I get a NetworkOnMainThreadExecption below is my AsyncTask. What am I doing wrong? If I remove the runOnUiThread I get a Only the original thread that created a view hierarchy can touch its views error which I think means that any updated to the UI need to be done in a Thread? So when I put the updates in the Thread I get NetworkOnMainThreadExecption error.
private class runBabyRun extends AsyncTask<Void, Integer, String> {
final TextView temperature = (TextView) findViewById(R.id.mTemp4);

What is causing the NetworkOnMainThreadException is the following line
String clientraw = reader.readLine();
reading from a Stream obtained from a http call, is still a blocking operation and it has to be performed on a background thread
I got a very annoying problem now with my android development. I have a list which loading a bunch of content, each is an xml file with different address. Which means I need to sends bunch of http get request to server.
The problem if the request is less than roughly 180 times, I mean continues, very fast http request, the app just works fine. When the amount reach around 180, the connection to internet of the whole device will be lost. That means not only the app won't work, even the default browser or other apps which require internet will also not work.
This will recover after 1 minutes or two. But during this time there are no internet connection.
I do have set permissions in mifest file.
Here is my code for http connection:
public class HTTPService {
private static String response;
public HTTPService() {
response = null;
}
public static String httpGet(String requestURL) {
//Reset response's value to null
response = null;
//DEBUG LOG
Log.i("HTTPService", "Start GET request with URL " + requestURL);
//this function will do http getting action and response checking at same time.
//and assign proper information into the response string.
executeRequest(new HttpGet(requestURL));
Log.i("HTTPService", "GET request return with: " + response);
return response;
}
public static String httpPost(String requestURL, String postString) throws Exception {
//Assemble POST request
HttpPost request = new HttpPost(requestURL);
StringEntity input = new StringEntity(postString);
input.setContentType(CommonCodes.CONTENT_TYPE);
request.setEntity(input);
//DEBUG LOG

executeRequest(request);
return response;
}

Any advice will be welcome! I'm thinking if this is caused by running up of ports. But I don't know how to solve it. Thank you!
Lucky....I solved it.
The problem is I have too many HTTP Clients instance, which used up all ports on the Phone.
Android have a max connection limit, and it takes time to release the ports which are been used. So if the requests are heavy and happens in very short time, the device just won't got enough time to release them.
The solution is instead of using new client every time, use only one client for all request.
Adding this to the code:
private static HttpClient client;
public static synchronized void createHttpClient() {
if(client == null) {
Log.i("HTTPService", "Create Client");
client = sslHttpClient();
}
}
Then call this constructor from beginning of the application.
Then replace everywhere where create new http client with the static client.
Problem solved, I will go for a beer.
