I have restlet sample client program which sends the digest request. Similar to this I need java client program which sends a digest request using HttpClient api. Can anybody send me sample code. Thanks in advance.
Reference reference = new Reference("http://localhost:8092/authenticate");
Client client = new Client(Protocol.HTTP);
Request request = new Request(Method.GET, reference);
Response response = client.handle(request);
System.out.println("response: "+response.getStatus());
Form form = new Form();
form.add("username", "rajesh");
form.add("uri", reference.getPath());
// Loop over the challengeRequest objects sent by the se开发者_开发知识库rver.
for (ChallengeRequest challengeRequest : response
.getChallengeRequests()) {
// Get the data from the server's response.
if (ChallengeScheme.HTTP_DIGEST
.equals(challengeRequest.getScheme())) {
Series<Parameter> params = challengeRequest.getParameters();
form.add(params.getFirst("nonce"));
form.add(params.getFirst("realm"));
form.add(params.getFirst("domain"));
form.add(params.getFirst("algorithm"));
form.add(params.getFirst("qop"));
}
}
// Compute the required data
String a1 = Engine.getInstance().toMd5(
"rajesh" + ":" + form.getFirstValue("realm") + ":" + "rajesh");
String a2 = Engine.getInstance().toMd5(
request.getMethod() + ":" + form.getFirstValue("uri"));
form.add("response", Engine.getInstance().toMd5(
a1 + ":" + form.getFirstValue("nonce") + ":" + a2));
ChallengeResponse challengeResponse = new ChallengeResponse(
ChallengeScheme.HTTP_DIGEST, "", "");
challengeResponse.setCredentialComponents(form);
// Send the completed request
request.setChallengeResponse(challengeResponse);
response = client.handle(request);
// Should be 200.
System.out.println(response.getStatus());
Have you tried the following:
ChallengeResponse challengeResponse = new ChallengeResponse(challengeRequest, "rajesh", <password>);
Here you go:
HttpClient client = new HttpClient();
Credentials creds = new UsernamePasswordCredentials(username, password);
client.getState().setCredentials(new AuthScope(host, port, realmName), creds);
GetMethod get = new GetMethod(url);
get.setDoAuthentication(true);
client.getParams().setAuthenticationPreemptive(true); // seems to be necessary in most cases
client.getParams().setParameter(AuthPolicy.AUTH_SCHEME_PRIORITY, Collections.singleton(AuthPolicy.DIGEST));//need to register DIGEST scheme not the basic
client.getAuthSchemes().register(AuthPolicy.DIGEST, new DigestSchemeFactory());
client.executeMethod(get);
result = get.getResponseBodyAsString();
