Re: [xwiki-users] xWiki RESTful/HTTP Connection
That's because what Mohamed is referring is the old (3.x) HttpClient
and not the new (4.x) one which have different (sometime very
different) API.
The main issue you have is probably the fact that XWiki does not ask
the client for credential by default since anonymous access is valid.
That means you need to force preemptive authentication which is very
easy in 3.x (just a call to setAuthenticationPreemptive like in
Mohamed's example) and quite harder in 4.x (they find dangerous to
support it like they used to...).
You can find various examples on Google and the official documentation
is on
https://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html
(section "4.6. Preemptive authentication").

Re: [xwiki-users] xWiki RESTful/HTTP Connection
Thank you for your response! As far as I know there is no PutMethod (which you use in your code) class in new versions of Apache's HTTP library. Same goes for many other methods which. Or maybe I'm just missing the point and there IS a library with required Classes and Methods of which I know nothing about (if it's true then I would be really grateful if your provide me a link). -- View this message in context: http://xwiki.475771.n2.nabble.com/xWiki-RESTful-HTTP-Connection-tp7599026p7599028.html Sent from the XWiki- Users mailing list archive at Nabble.com. ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
Re: [xwiki-users] xWiki RESTful/HTTP Connection
Hi,
You can use the new version of Apache's HTTP library, as follows, hope
it'll help you.
public class RestTest {
/**
* Create and initialize the http client.
*
* @return an HttpClient object
*/
HttpClient getClient(host, port, username, password) {
HttpClient httpClient = new HttpClient();
httpClient.getParams().setAuthenticationPreemptive(true);
httpClient.getState().setCredentials(
new AuthScope(host, port, AuthScope.ANY_REALM),
new UsernamePasswordCredentials(username, password)
);
return httpClient;
}
public static void main(String[] args) throws IOException {
// Get request example
HttpClient httpClient = getClient(yourHost, yourPort, yourUsername,
yourPassword);
GetMethod getMethod = new GetMethod(getURL);
getMethod.addRequestHeader("Accept", "application/json");
getMethod.setDoAuthentication( true );
String getURL = "your get url";
try {
int status = httpClient.executeMethod(getMethod);
System.out.println(getMethod.getResponseBodyAsString());
} catch (Exception e) {
//...
} finally {
// release any connection resources used by the method
getMethod.releaseConnection();
}
// Put request example
String putURL = "your put url";
PutMethod putMethod = new PutMethod(putURL);
putMethod.addRequestHeader("Accept", "application/json");
putMethod.setDoAuthentication( true );
try {
int status = httpClient.executeMethod(putMethod);
System.out.println(putMethod.getResponseBodyAsString());
} catch (Exception e) {
// ...
} finally {
// release any connection resources used by the method
putMethod.releaseConnection();
}
}
}
Best regards,
Mohamed.
