Using SOAP UI, I am able to successfully invoke the REST GET call with basic authentication
GET https://app.test.com/testing/rest/authentication-point/authentication HTTP/1.1
Accept-Encoding: gzip,deflate
Authorization: Basic aPOjYVclOmIzABFhZjVpJES=
Host: app.test.com
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
I received response code as 200.
Similar request, When I tried to invoke via java client, it is giving 400 status code.
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("User", "Password"));
final HttpClientContext context = HttpClientContext.create();
context.setCredentialsProvider(credsProvider);
HttpClient client = HttpClientBuilder.create().build();
HttpResponse response = null;
response = client.execute(
new HttpGet("https://app.test.com/testing/rest/authentication-point/authentication"),
context);
int statusCode = response.getStatusLine().getStatusCode();
This code worked properly when the host was HTTP. Recently a VIP is added and made as HTTPS, after which it is not working. Please suggest a fix for this.
You need to use ssl with http client:
TrustStrategy acceptingTrustStrategy = (cert, authType) -> true;
SSLSocketFactory sf = new SSLSocketFactory(
acceptingTrustStrategy, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("https", 8443, sf));
ClientConnectionManager ccm = new PoolingClientConnectionManager(registry);
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("User", "Password"));
final HttpClientContext context = HttpClientContext.create();
context.setCredentialsProvider(credsProvider);
DefaultHttpClient httpClient = new DefaultHttpClient(ccm);
HttpGet getMethod = new HttpGet(new HttpGet("https://app.test.com/testing/rest/authentication-point/authentication"),context);
HttpResponse response = httpClient.execute(getMethod);
int statusCode = response.getStatusLine().getStatusCode();
After trying out so many options, below code worked for me.
HttpHost targetHost = new HttpHost("app.test.com", 443, "https");
AuthCache authCache = new BasicAuthCache();
authCache.put(targetHost, new BasicScheme());
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("User", "Password"));
final HttpClientContext context = HttpClientContext.create();
context.setCredentialsProvider(credsProvider);
context.setAuthCache(authCache);
HttpClient client = HttpClientBuilder.create().build();
HttpResponse response = null;
response = client.execute(
new HttpGet("https://app.test.com/testing/rest/authentication-point/authentication"),
context);
After defining a HTTP host with scheme as https, and setting them to context using AuthCache, the call went through successfully.

I am trying to use httpclient to make make a call to Jenkins to get a list of jobs.
When I run my code, I get an UnknownHostException.
I tried to make the same request using curl and I was able to get the result. I am not sure how to interpret this.
void nwe() throws ClientProtocolException, IOException {
HttpHost target = new HttpHost("https://<JENKINS_URL>/api");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope(target.getHostName(), target.getPort()),
new UsernamePasswordCredentials("username", "password"));
CloseableHttpClient httpclient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
HttpGet httpGet = new HttpGet("/json");
httpGet.setHeader("Content-type", "application/json");
BasicScheme basicAuth = new BasicScheme();
HttpClientContext localContext = HttpClientContext.create();
CloseableHttpResponse response1 = httpclient.execute(target, httpGet, localContext);
System.out.println(response1.getStatusLine());
}
The CURL command on the same URL gives me the expected output
Thanks,
Amar
Read the JavaDoc for HttpHost:
Parameters: hostname - the hostname (IP or DNS name)
So you should use just (omit the protocol and context):
HttpHost target = new HttpHost( "<JENKINS_URL>" );
and then HttpGet the /api/json part.
Cheers,
I am trying to post a SharePoint list item to a SharePoint 2010 list using Java client.
I am able to read the SP list items using below code but I am not sure how to write to the SharePoint.
For the post operation, I am getting http 401 error.
Any guidance will be greatly appreciated.
GET Operation:
String url = "https://organization.company.com/sites/Ateam/_vti_bin/ListData.svc/TableLoadInfo"; DefaultHttpClient client = new DefaultHttpClient();
NTCredentials credentials = new NTCredentials(username, password, hostname, domain);
AuthScope scope = new AuthScope(hostname, 443);
SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(null, new TrustManager[] { trustmanager }, null);
SSLSocketFactory sf = new SSLSocketFactory(sslcontext, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Scheme https = new Scheme("https", 443, sf);
client.getConnectionManager().getSchemeRegistry().register(https);
client.getCredentialsProvider().setCredentials(scope, credentials);
HttpGet request = new HttpGet(url);
//request.addHeader("Accept", "application/xml");
request.addHeader("Accept", "application/json;odata=verbose");
HttpResponse response = client.execute(request);
POST Operation:
String url = "https://organization.company.com/sites/Ateam/_vti_bin/ListData.svc/TableLoadInfo";
DefaultHttpClient client = new DefaultHttpClient();
NTCredentials credentials = new NTCredentials(username, password, hostname, domain);
AuthScope scope = new AuthScope(hostname, 443);
SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(null, new TrustManager[] { trustmanager }, null);
SSLSocketFactory sf = new SSLSocketFactory(sslcontext, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Scheme https = new Scheme("https", 443, sf);
client.getConnectionManager().getSchemeRegistry().register(https);
client.getCredentialsProvider().setCredentials(scope, credentials);
// POST a data
HttpPost request = new HttpPost(url);
request.addHeader("Accept", "application/json;odata=verbose");
request.addHeader("Content-type", "application/json;odata=verbose");
// request.addHeader("X-RequestDigest", FormDigestValue);
request.addHeader("X-HTTP-Method", "POST");
request.addHeader("If-Match", "*");
JSONStringer json = (JSONStringer) new JSONStringer().object().key("Table_Name").value("TableName 1")
.key("Load_Frequency").value("Weekly").key("Cycle").value("CURRENT").endObject();
StringEntity se = new StringEntity(json.toString());
request.setEntity(se);
HttpResponse response = client.execute(request);
When you post data to SharePoint you have to add "FormDigestValue" inside the header.
Please Note you have commented the line "request.addHeader("X-RequestDigest", FormDigestValue);".
That is the reason you get 401 Error.
First you have to get the "FormDigestValue" value form your current site.
Then add that value inside the header.
Following Code shows the way to get the FormDigestValue.
String digestqueryURL = serverurl + subsite + "/" + "_api/contextinfo";
HttpPost httpPost = new HttpPost(digestquery);
httpPost.addHeader("Accept", "application/json;odata=verbose");
httpPost.addHeader("X-ClientService-ClientTag", "SDK-JAVA");
HttpResponse response = httpClient.execute(httpPost);
byte[] content = EntityUtils.toByteArray(response.getEntity());
String jsonString = new String(content, "UTF-8");
JSONObject json = new JSONObject(jsonString);
String FormDigestValue = json.getJSONObject("d")
.getJSONObject("GetContextWebInformation")
.getString("FormDigestValue");
Then add the FormDigestValue to the header when you do the post operations.
request.addHeader("X-RequestDigest", FormDigestValue);
My problem is i'm trying to get into scopus using a crawler but it requires my crawler to enter the site through my school proxy server. I tried authenticating but it keep responding with 401 status.
public void testConnection() throws ClientProtocolException, IOException {
DefaultHttpClient httpclient = new DefaultHttpClient();
List<String> authpref = new ArrayList<String>();
authpref.add(AuthPolicy.NTLM);
httpclient.getParams().setParameter(AuthPNames.TARGET_AUTH_PREF, authpref);
NTCredentials creds = new NTCredentials("username","password","ezlibproxy1.ntu.edu.sg","ntu.edu.sg");//this is correct
httpclient.getCredentialsProvider().setCredentials(AuthScope.ANY, creds);
HttpHost target = new HttpHost("ezlibproxy1.ntu.edu.sg", 443, "https");//this is correct
// Make sure the same context is used to execute logically related requests
HttpContext localContext = new BasicHttpContext();
// Execute a cheap method first. This will trigger NTLM authentication
HttpGet httpget = new HttpGet("http://www-scopus-com.ezlibproxy1.ntu.edu.sg/authid/detail.url?authorId=14831850700");
HttpResponse response = httpclient.execute(target, httpget, localContext);
HttpEntity entity = response.getEntity();
System.out.println(EntityUtils.toString(entity));
int statusCode = response.getStatusLine().getStatusCode();
System.out.println("Status Code:" + statusCode);
}
The status code respond is 401 (unauthorised).
Any suggestion on this?
I'm trying to access a RESTful web service through the Android Emulator on my PC, which uses a proxy to connect to the internet.
I have code working fine to access the web service on an actual Android device that has its own data connection with the following code:
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpGet request = new HttpGet("http://mytesturl.com/services/serviceName");
UsernamePasswordCredentials creds =
new UsernamePasswordCredentials("username", "password");
request.addHeader(BasicScheme.authenticate(creds, "UTF-8", false));
HttpResponse response = client.execute(request);
I've tried a number of approaches to try to get the Emulator to allow connection through the proxy, but none have worked.
Note, I do have the INTERNET enabled in AndroidManifest.xml:
<uses-permission android:name="android.permission.INTERNET" />
Attempt 1 - Setting Properties:
This produces an UnknownHostException for the URL of my service at the execute() call
Properties props = System.getProperties();
props.put("http.proxyHost", "httpproxy.mycompany.com");
props.put("http.proxyPort", "80");
Attempt 2 - Setting the proxy in the DefaultHttpClient:
This produces an UnknownHostException for the actual proxy
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpHost proxy = new HttpHost("httpproxy.mycompany.com", 80);
client.getCredentialsProvider().setCredentials(
new AuthScope("httpproxy.mycompany.com", 80),
new UsernamePasswordCredentials("username", "password"));
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);
HttpGet request = new HttpGet("http://mytesturl.com/services/serviceName");
UsernamePasswordCredentials cred =
new UsernamePasswordCredentials("username", "password");
request.addHeader(BasicScheme.authenticate(cred, "UTF-8", false));
HttpResponse response = client.execute(request);
Attempt 3 - Setting the proxy in the HttpGet
This produces an UnknownHostException for the URL in my HttpGet
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpGet request = new HttpGet("http://mytesturl.com/services/serviceName");
UsernamePasswordCredentials cred =
new UsernamePasswordCredentials("username", "password");
request.addHeader(BasicScheme.authenticate(cred, "UTF-8", false));
Header bs = new BasicScheme().authenticate(
new UsernamePasswordCredentials("username", "password"),
request);
request.addHeader("Proxy-Authorization", bs.getValue());
HttpResponse response = client.execute(request);
I'm not sure what else to try. I'm open to any suggestions.
Having the same problem, I succeeded with a variation on attempt 3 (code below), the cruicial difference being the setProperty statements. Note that the web service I am calling does not require authentication so I'm only setting the proxy authorization header.
System.setProperty("java.net.useSystemProxies", "false");
System.setProperty("http.proxyHost", "123.56.7.9");
System.setProperty("http.proxyPort", "8080");
DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
HttpGet request = new HttpGet("web service url");
Header bs = new BasicScheme().authenticate(
new UsernamePasswordCredentials("NETWORKID", "netpassword"),
request);
request.addHeader("Proxy-Authorization", bs.getValue());
HttpResponse response = client.execute(request);
did you use -http-proxy http://: emulator command line option or "Settings" -> "Wireless & Networks" -> "Mobile Networks" -> "Access Point Names" -> "Telkila" or Home > Menu > Settings > Wireless Controls > Mobile Networks > Access Point Names?
I am trying to develop a java http client with apache httpcomponents 4.0.1. This client calls the page "https://myHost/myPage". This page is protected on the server by a JNDIRealm with a login form authentication, so when I try to get https://myHost/myPage I get a login page. I tried to bypass it unsuccessfully with the following code :
//I set my proxy
HttpHost proxy = new HttpHost("myProxyHost", myProxyPort);
//I add supported schemes
SchemeRegistry supportedSchemes = new SchemeRegistry();
supportedSchemes.register(new Scheme("http", PlainSocketFactory
.getSocketFactory(), 80));
supportedSchemes.register(new Scheme("https", SSLSocketFactory
.getSocketFactory(), 443));
// prepare parameters
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "UTF-8");
HttpProtocolParams.setUseExpectContinue(params, true);
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params,
supportedSchemes);
DefaultHttpClient httpclient = new DefaultHttpClient(ccm, params);
httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,
proxy);
//I add my authentication information
httpclient.getCredentialsProvider().setCredentials(
new AuthScope("myHost/myPage", 443),
new UsernamePasswordCredentials("username", "password"));
HttpHost host = new HttpHost("myHost", 443, "https");
HttpGet req = new HttpGet("/myPage");
//show the page
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String rsp = httpClient.execute(host, req, responseHandler);
System.out.println(rsp);
When I run this code, I always get the login page, not myPage. How can I apply my credential parameters to avoid this login form?
Any help would be fantastic
HttpClient doesn't support form login. What you are trying to do is Basic Auth, which does't work with form login.
You can simply trace the form post for login page and send the POST request from HttpClient.
