Hello I switched from RestTemplate to HttpClient from java 11. I want to switch from OAuth2RestTemplate to HttpClient from java 11 also.
I cannot find any materials about using HttpClient with OAuth2. Is it possible in easy way?
And is it good idea? Or should I use WebClient from spring?
I just did post using HttpClient to grab OAuthToken and then I added token to headers of next requests.
String tokenRequest =
"client_id="
+ lmGatewayCorrectClientId
+ "&client_secret="
+ lmGatewayCorrectClientSecret
+ "&grant_type="
+ lmGatewayCorrectGrantType;
HttpClient oAuth2Client = HttpClient.newBuilder().build();
HttpRequest oAuth2Request =
HttpRequest.newBuilder()
.header(CONTENT_TYPE, APPLICATION_FORM_URLENCODED_VALUE)
.uri(URI.create(lmGatewayCorrectAccessTokenUri))
.POST(HttpRequest.BodyPublishers.ofString(tokenRequest))
.build();
HttpResponse<String> oAuth2Response = null;
try {
oAuth2Response = oAuth2Client.send(oAuth2Request, HttpResponse.BodyHandlers.ofString());
} catch (Exception e) {
logger.error(e.getMessage(), e);
}

I am trying to connect to pay by link by json.
We first tried with json and it worked like a charm.
I used the code postman provided to create this,
But we keep getting 400 bad request,
If we change the credentials we get unauthorized, se wo know it's not that
But if we go look in the request log of pay by link we see that the request send from java does not appear here at all, it does not show error, but nothing.
Does anybody know how we can fix it?
Thanks in advance!
Sincerely,
Laurens

First I wanted to authenticate my java application using OkHttp and then after authentication the response returns a session ID(key) that I wanted to use in subsequent API calls. below is the code that I am using to achieve this.
String url = "my application url";
String username = "xxx";
String password = "zzz";
String userpass = username + ":" + password;
String basicAuth = "Basic :" + new String(Base64.getEncoder().encode(userpass.getBytes()));
OkHttpClient client = new OkHttpClient();
Response response ;
Request request = new Request.Builder()
.url(url)
.addHeader("Authorization", basicAuth)
.build();
response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
System.out.println(response.body().string());
but its throwing an error saying
{"responseStatus":"FAILURE","responseMessage":"Request method 'GET' not supported","errorCodes":null,"errors":[{"type":"METHOD_NOT_SUPPORTED","message":"Request method 'GET' not supported"}],"errorType":"GENERAL"}
can someone please help me to solve this. or if any have any other idea to authenticate a java application using okhttp then please suggest...
You should use the helper classes to avoid most of the logic for username and password.
https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/Authenticate.java
String credential = Credentials.basic("jesse", "password1");
return response.request().newBuilder()
.header("Authorization", credential)
.build();
Assuming this API is POST and not GET also follow
https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PostString.java
Request request = new Request.Builder()
.url("https://api.github.com/markdown/raw")
.post(RequestBody.create(postBody, MEDIA_TYPE_MARKDOWN))
.build();
You had it all right already. Just a small fix needed:
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userpass.getBytes()));
i.e you just need to remove extra ':' as it's already taken care of in .addHeader("Authorization", basicAuth) part.
I tried this with openid-connect, and it is working. I want same thing for SAML. FYI, I'm doing demo with Keycloak. So I already changed protocol from openid-connet to SAML inside Keycloak console/dashboard.
Code:
#Override
protected Boolean doInBackground(String... params) {
try {
OkHttpClient client = new OkHttpClient().newBuilder()
.build();
MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
/*For openid-connect*/
//RequestBody body = RequestBody.create(mediaType, "client_id=lifetrenz-client-1&username=test&password=test#123&grant_type=password&client_secret=c89b1eed-136d-445f-bfb0-e7e2bdac89ee");
/*For SAML*/
RequestBody body = RequestBody.create(mediaType, "client_id=lifetrenz-client-1&username=test&password=test#123&grant_type=password");
/*URL is changing manually accoridng to protocol*/
Request request = new Request.Builder()
.url("http://10.0.2.2:8080/auth/realms/Lifetrenz/protocol/saml/token")
.method("POST", body)
.addHeader("Content-Type", "application/x-www-form-urlencoded")
.build();
Response response = client.newCall(request).execute();
data = "CODE: " + response.code() + "\n" + "MESSAGE: " + response.message() + "\n" + "BODY: " + response.body().string();
return true;
} catch (Exception ex) {
ex.printStackTrace();
return false;
}
}
Please guide me. And please answer in Java instead of Kotlin.
You can't just change the protocol to SAML and then send OpenID Connect parameters.
Here's an example of a SAML request. The parameters are completely different.
And you can't use REST API. SAML uses browser redirects.
Not a Keycloak expert but your application needs a client-side SAML stack.
After trying other solutions from HttpURLConnection Invalid HTTP method: PATCH
I am getting Invalid HTTP Method: PATCH Exception with JAVA 7.
Updating JAVA is not in option so i have to stick to the workarounds.
I am using Invocation to invoke the request like this
Invocation invoke = reqBuilder.build(getHTTPVerb(), Entity.entity(requestJSON, MediaType.APPLICATION_JSON));
getWebTarget().request(MediaType.APPLICATION_JSON).header("Authorization", getAuthorization()).accept(MediaType.APPLICATION_JSON);
getHTTPVerb() returns String "POST" or "PATCH".
With PATCH method I am having problem.
In the mentioned question, i have not tried one solution with:
conn.setRequestProperty("X-HTTP-Method-Override", "PATCH");
conn.setRequestMethod("POST");
conn is HttpURLConnection instance.
But I am not sure how I can get HttpURLConnection from Invocation class or any property.
Any pointers or help would be highly appreciated.
An example of PATCH method with apache http client:
try {
//This is just to avoid ssl hostname verification and to trust all, you can use simple Http client also
CloseableHttpClient httpClient = HttpClientBuilder.create().setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
.setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE).build();
HttpPatch request = new HttpPatch(REST_SERVICE_URL);
StringEntity params = new StringEntity(JSON.toJSONString(payload), ContentType.APPLICATION_JSON);
request.setEntity(params);
request.addHeader(org.apache.http.HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE);
request.addHeader(HttpHeaders.ACCEPT, MediaType.APPLICATION_JSON_VALUE);
request.addHeader(HttpHeaders.AUTHORIZATION, OAuth2AccessToken.BEARER_TYPE + " " + accessToken);
HttpResponse response = httpClient.execute(request);
String statusCode = response.getStatusLine().getStatusCode();
} catch (Exception ex) {
// handle exception here
}
Equivalent example with RestTemplate:
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("Authorization", OAuth2AccessToken.BEARER_TYPE + " " + accessToken);
final HttpEntity<String> entity = new HttpEntity<String>(JSON.toJSONString(payload), headers);
RestTemplate restTemplate = new RestTemplate();
try {
ResponseEntity<String> response = restTemplate.exchange(REST_SERVICE_URL, HttpMethod.PATCH, entity, String.class);
String statusCode = response.getStatusCode();
} catch (HttpClientErrorException e) {
// handle exception here
}
I'm send a request to YouTrack api to create issue.
String url = yBaseUrl + "/rest/issue?Task&"+ URLEncoder.encode(subject)+"&"+URLEncoder.encode(desc);
HttpClient client = new DefaultHttpClient();
HttpPut request = new HttpPut(url);
// add request header
((DefaultHttpClient) client).setCookieStore(cookie);
HttpResponse response = null;
//client.execute(post);
try {
response = client.execute(request);
System.out.println(response.getStatusLine().getStatusCode());
} catch (IOException e) {
e.printStackTrace();
}
result - 403 code.
Why setCookieStore not working?
The problem was incorrect api url. Need use /rest/issue?project=Task&summary="+ URLEncoder.encode(subject)... The question is closed
