Android HttpClient for my PC - java

I need to develop an helper class on top of org.apache.httpclient for my android application. Following code works fine for android, but not for JavaSE 1.6 in my PC.
Question is: Can I use org.apache.httpclient both for android and for PC? If I cant: what is your http client library advise?
I want to develop one helper class and use it at all.
Here is the code that works fine in android but some classes cannot be resolved for on Java SE 1.6.
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
public class HTTPClient {
public static void connect(String url)
{
HttpClient httpclient = new DefaultHttpClient();
// Prepare a request object
HttpGet httpget = new HttpGet(url);
// Execute the request
HttpResponse response;
try {
response = httpclient.execute(httpget);
// Examine the response status
// Get hold of the response entity
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
// to worry about connection release
if (entity != null) {
// A Simple JSON Response Read
InputStream instream = entity.getContent();
String result= convertStreamToString(instream);
// now you have the string representation of the HTML request
instream.close();
}
} catch (Exception e) {}
}
private static String convertStreamToString(InputStream is) {
/*
* To convert the InputStream to String we use the BufferedReader.readLine()
* method. We iterate until the BufferedReader return null which means
* there's no more data to read. Each line will appended to a StringBuilder
* and returned as String.
*/
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
}

Yes you can, you should avoid naming your client helper class as the same thing as an already defined class. Although Java is case sensitive, it is confusing will trip you up when you least expect it. It may even be guilty for causing this problem. Why not call it HttpClientHelper as that is what it truly is.
Here's an example of HttpClient http://hc.apache.org/httpclient-3.x/tutorial.html

FileNotFoundException for URL that works in browser

I am trying to use an API from https://us.mc-api.net/ for a project and I have made this as a test.
public static void main(String[] args){
try {
URL url = new URL("http://us.mc-api.net/v3/uuid/193nonaxishsl/csv/");
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
}
catch (MalformedURLException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
System.out.println("I/O Error");
}
}
}
And this is giving me an IOException error but when ever I open the same page in my web browser I get
false,Unknown-Username
which is what I want to get from the code. I am new and don't really know why it is happening or why.
EDIT: StackTrace
java.io.FileNotFoundException: http://us.mc-api.net/v3/uuid/193nonaxishsl/csv/
at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(Unknown Source)
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
at java.net.URL.openStream(Unknown Source)
at com.theman1928.Test.Main.main(Main.java:13)
The URL is returning status code 404 and therefore the input stream (mild guess here) is not being created and therefore is null. Sort the status code and you should be OK.
Ran it with this CSV and it is fine: other csv
If the error code is important to you then you can use HttpURLConnection:
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
System.out.println("code:"+conn.getResponseCode());
In that way you can process the response code before proceeding with a quick if-then-else check.
I tried it with the Apache HTTP libraries. The API endpoint seems to return a status code of 404, hence your error. Code I used is below.
public static void main(String[] args) throws URISyntaxException, ClientProtocolException, IOException {
HttpClient httpclient = HttpClients.createDefault();
URIBuilder builder = new URIBuilder("http://us.mc-api.net/v3/uuid/193nonaxishsl/csv/");
URI uri = builder.build();
HttpGet request = new HttpGet(uri);
HttpResponse response = httpclient.execute(request);
System.out.println(response.getStatusLine().getStatusCode()); // 404
}
Switching out the http://us.mc-api.net/v3/uuid/193nonaxishsl/csv/ with www.example.com or whatever returns a status code of 200, which further proves an error with the API endpoint. You can take a look at [Apache HTTP Components] library here.
This has to do with how the wire protocols are working in comparison with the java.net classes and an actual browser. A browser is going to be much more sophisticated than the simple java.net API you are using.
If you want to get the equivalent response value in Java, then you need to use a richer HTTP API.
This code will give you the same response as the browser; however, you need to download the Apache HttpComponents jars
The code:
import java.io.BufferedReader;

try
{

HttpGet httpGet = new HttpGet(url);
getResponseFromHTTPReq(httpGet, url);
}
catch (Throwable e)
{
e.printStackTrace();
}
}
private static String getResponseFromHTTPReq(HttpUriRequest httpReq, String url)
{
HttpClient httpclient = HttpClients.createDefault();
// Execute and get the response.
HttpResponse response = null;
HttpEntity entity = null;
try
{
response = httpclient.execute(httpReq);
entity = response.getEntity();
}
catch (IOException ioe)
{
throw new RuntimeException(ioe);
}
if (entity == null)
{
String errMsg = "No response entity back from " + url;
throw new RuntimeException(errMsg);
}
String returnRes = null;
InputStream is = null;
BufferedReader buf = null;
try
{
is = entity.getContent();
buf = new BufferedReader(new InputStreamReader(is, "UTF-8"));
System.out.println("Response Code : " + response.getStatusLine().getStatusCode());
StringBuilder sb = new StringBuilder();
String s = null;
while (true)
{
s = buf.readLine();
if (s == null || s.length() == 0)
{
break;
}
sb.append(s);
}
returnRes = sb.toString();
System.out.println("Response: [" + returnRes + "]");
}
catch (UnsupportedOperationException | IOException e)
{
throw new RuntimeException(e);
}
finally
{
if (buf != null)
{
try
{
buf.close();
}
catch (IOException e)

}
}
if (is != null)
{
try
{

Java: ConnectException/Cannot find or load Main-Class

So in a nutshell, I'm just trying to get a small working skeleton program that I can use to sort of learn about Http communication and "feel" my way around to figure out what I will eventually need for a bigger program I am working on. This particular code here is actually just a chopped up version of an example from the Apache libraries. I could compile the examples listed on the Apache website, but they didn't run properly, giving a "java.net.ConnectException". I figured it had to do with Windows c-blocking a program like this from making a connection, and that I would need to run it as an administrator. I then tried taking the code and throwing it into an executable jar file, but I get a Cannot-find-or-load-main-class error. Am I an idiot or is the Apache library a little outdated/not fit for Win 8/something else?
Code below:
package NewProject;
import java.net.Socket;
import org.apache.http.ConnectionReuseStrategy;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.impl.DefaultBHttpClientConnection;
import org.apache.http.impl.DefaultConnectionReuseStrategy;
import org.apache.http.message.BasicHttpRequest;
import org.apache.http.protocol.HttpCoreContext;

import org.apache.http.protocol.RequestUserAgent;
import org.apache.http.util.EntityUtils;
class NewProject
{
public static void main(String[] args) throws Exception
{
HttpProcessor httpproc = HttpProcessorBuilder.create()
.add(new RequestContent())
.add(new RequestTargetHost())
.add(new RequestConnControl())
.add(new RequestUserAgent("Test/1.1"))
.add(new RequestExpectContinue(true)).build();
HttpRequestExecutor httpexecutor = new HttpRequestExecutor();
HttpCoreContext coreContext = HttpCoreContext.create();
HttpHost host = new HttpHost("localhost", 8080);
coreContext.setTargetHost(host);
Out os = new Out("TestOut.txt");
DefaultBHttpClientConnection conn = new DefaultBHttpClientConnection(8 * 1024);
ConnectionReuseStrategy connStrategy = DefaultConnectionReuseStrategy.INSTANCE;
try
{
String[] targets =
{
"http://www.google.com/"
};
for (int i = 0; i < targets.length; i++)
{
if (!conn.isOpen())
{
Socket socket = new Socket(host.getHostName(), host.getPort());
conn.bind(socket);
}
BasicHttpRequest request = new BasicHttpRequest("GET", targets[i]);
os.println(">> Request URI: " + request.getRequestLine().getUri());
httpexecutor.preProcess(request, httpproc, coreContext);
HttpResponse response = httpexecutor.execute(request, conn, coreContext);
httpexecutor.postProcess(response, httpproc, coreContext);
os.println("<< Response: " + response.getStatusLine());
os.println(EntityUtils.toString(response.getEntity()));
os.println("==============");
if (!connStrategy.keepAlive(response, coreContext))
{
conn.close();
}
else
{
os.println("Connection kept alive...");
}
}
}
catch (IndexOutOfBoundsException iob)
{
os.println("What happened here?");
}
finally
{
conn.close();
}
return;
}
}
... they didn't run properly, giving a "java.net.ConnectException"
That could be caused by lots of things. There are clues in the exception message ... which you chose not to share with us.
... "Cannot find or load Main-Class"
Again multiple possible causes, and there are clues in the exception message ... which you chose not to share with us.
But the fact that you have created a JAR file plus the "Main-Class" hint in the error message fragment you provided suggest that you made a mistake in the creation of the JAR file; i.e. you used the wrong name for the "Main-Class" attribute.
Given that source code, the "Main-Class" attribute should be "NewProject.NewProject". I suspect you set it to something else.
A second possibility is that you haven't handled the dependency on the Apache library correctly. The Apache classes need to be on the classpath specified by the JAR file. (You can't use a -cp argument or $CLASSPATH when you launch with java -jar.)
Am I an idiot or is the Apache library a little outdated/not fit for Win 8/something else?
There is nothing wrong with the Apache library.
The code you posted seems a little low level (e.g. interacting directly with Socket connections). The code posted below should give you what it sounds like you are looking for. The classes used also give you a lot of inroads into setting and getting http parameters (e.g. headers, time-outs, etc).

Emulator won't execute AsyncTask.execute().get()

I have a program to download JSON Strings from a server. Things were working fine up until recently, when I try to call
jsonReader.execute(getUrl).get();
Where jsonReader is an AsyncTask to download JSON Strings and getUrl is the URL to execute. This method never gets executed, the weird thing is, it works on my phone.

Log.d(TAG,"Trying to get json from: " + id); <-- Last Log line to get printed when run on emulator
jsonReader.execute(getUrl).get();
} catch (Exception e) {
e.printStackTrace();
}
String jsonString = jsonReader.returnJSONString();
Log.d(TAG,"Downloaded: " + jsonString);
//System.out.println("JSON: " + jsonString);
JSONResponse jsonResponse = JSONResponse.convertJSONToResponse(jsonString);

I have tried restarting adb, making new AVD's but nothing seems to work, my only option is testing on my phone however, this is not desirable as I am developing for api 17. Thanks for your help !
There are a few threading rules that must be followed for this class to work properly:
The AsyncTask class must be loaded on the UI thread. This is done automatically as of JELLY_BEAN.
The task instance must be created on the UI thread.
execute(Params...) must be invoked on the UI thread.
Do not call onPreExecute(), onPostExecute(Result), doInBackground(Params...), onProgressUpdate(Progress...) manually.
The task can be executed only once (an exception will be thrown if a second execution is attempted.)

Java - Perform a http Request POST and GET on the same connection

I have something I am trying to achieve.
I have a web application running on my localhost on port 8080.
I have a HTTP Server running on localhost:9005.
I have a JSP form that passes info to a servlet java class, that in turn performs the HTTP post to the URL on the HTTP Server localhost:9010 with the data string.
What I need to do is perform the POST and GET as part of the same connection. I have them working as two separate calls, but not on the same connection. It needs to be the same connection, as I post data, the HTTP Server takes this data, processes it and outputs unique data to this URL. Therefore the GET needs to be part of the same connection as he POST.
Can anyone please help?

Why don't you just return the result from the original POST?
In general you can't control connection reuse with HttpUrlConnection. You might be able to cast your connection to the specific implementation class and interfere with it but that's a horribly unstable way of doing it.
Apache HttpClient is probably a better option, given the requirements.
You can use Apache HTTP Client for this. Its very simple.
If you are using maven, just add the following lines into your POM file:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.3</version>
</dependency>
In this example, I'm submitting a POST request and after that a GET request.
Take a look:
public static String get(String p_url) throws IOException
{
CloseableHttpClient httpclient = HttpClients.createDefault();
// First request: POST
HttpPost httpPost = new HttpPost("http://the-api-url.com/Login/Auth&token=12345"));
CloseableHttpResponse response_post = httpclient.execute(httpPost);
System.out.println(response_post.getStatusLine());
HttpEntity entity_post = response_post.getEntity();
System.out.println(EntityUtils.toString(entity_post));
// Second request: GET
HttpGet httpGet = new HttpGet(p_url);
CloseableHttpResponse response_get = httpclient.execute(httpGet);
System.out.println(response_get.getStatusLine());
HttpEntity entity_get = response_get.getEntity();
System.out.println(EntityUtils.toString(entity_get));
response_post.close();
response_get.close();
return EntityUtils.toString(entity_get);
}

Android/Java: JSON HTTP Request

How can I make a request to get/download http://coolsite.com/coolstuff.json in Java/Android
Android supports all the standard java.net classes. The simplest way to retrieve content via HTTP is to call openStream() on your URL and read it:
URL url = new URL("http://coolsite.com/coolstuff.js");
InputStream in = url.openStream();
InputStreamReader reader = new InputStreamReader(in);
// read the JSON data
There are libraries for reading JSON in Java (see http://json.org/java), but since the format is really simple, you can parse it easily.
From a cached copy of:
How-to: Android as a RESTful Client
This is a how-to focused on creating a RESTful java object at Android. I’ve used HTTPClient, HTTPEntry, HTTPGet, HTTPResponse, JSONArray and JSONObject classes. I think it’ll be useful if we need to use a web-service from client application.
I’ve implemented a simple Java Object called RestClient which connects to a given Rest-JSON service. After connection, this object prints response content. Using this content, a JSONObject created. Then, RestClient prints the JSONObject’s content, parses all values of this object and prints them as well. And as a last job, RestClient pushes a sample value to the JSONObject.
I’ve uploaded RestClient. Hope it’ll be useful.
P.s: To get access to internet at Android, following field must be included to AndroidManifest.xml file of the project.
