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 server.
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());
