I was looking through different blogs, sites and stack overflow for my answer. I have an app which shares images with a server. They provide a API token for the authentication, and the authentication is using curl. Can any one tell me how can I use curl in my app. I have to pass url as API token + password+ the path in the same form to get authentication. Can any one suggest some tricks to get it done.?
Thanks in advance
Happy Coding
Edit
Code
public static String getRequest() {
StringBuffer stringBuffer = new StringBuffer("");
BufferedReader bufferedReader = null;
try {
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet();
URI uri = new URI("http://s1.campfirenow.com/room/5e1a1/speak.xml");
httpGet.setURI(uri);
httpGet.addHeader(BasicScheme.authenticate(
new UsernamePasswordCredentials("f48be786f212f1e35dd9s265b4675358123d838e53", "X"),
HTTP.UTF_8, false));
httpGet.setHeader("Content-Type", "application/xml");
HttpResponse httpResponse = httpClient.execute(httpGet);
This is the log cat response from the server (logcat output)

Sure you could always use wget for most tasks, but curl is more compatible with regards to protocols supported and also supports bi-directional transfers. The trouble is, however, Android doesn't support curl by default.
cURL is a command-line tool that lets you transfer data to/from a server using various protocols. In this case, the curl command will establish a communication to POST or GET data to/from Ubidots Server over HTTP and HTTPS. Below you will find the step-by-step to installing cURL in Windows, MacOSX and Linux.
Let's assume that you want to do the following request:
curl -u user:password http://sample.campfirenow.com/rooms.xml
In Android you would do as follow.
public static String getRequest() {
StringBuffer stringBuffer = new StringBuffer("");
BufferedReader bufferedReader = null;
try {
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet();
URI uri = new URI("http://sample.campfirenow.com/rooms.xml");
httpGet.setURI(uri);
httpGet.addHeader(BasicScheme.authenticate(
new UsernamePasswordCredentials("user", "password"),
HTTP.UTF_8, false));
HttpResponse httpResponse = httpClient.execute(httpGet);
InputStream inputStream = httpResponse.getEntity().getContent();
bufferedReader = new BufferedReader(new InputStreamReader(
inputStream));
String readLine = bufferedReader.readLine();
while (readLine != null) {
stringBuffer.append(readLine);
stringBuffer.append("\n");
readLine = bufferedReader.readLine();
}
} catch (Exception e) {
// TODO: handle exception
} finally {
if (bufferedReader != null) {
try {
bufferedReader.close();
} catch (IOException e) {
// TODO: handle exception
}
}
}
return stringBuffer.toString();
}
You can change HttpGet to HttpPost / HttpPut / HttpDelete depending on what you need to access.
Cheers.
