I want to push some archived files into GITHub from my local spring application.
repos/{:user}/{:repo}/git/refs/heads/{:branchname}
{
SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("XXXXXX", 8080));
requestFactory.setProxy(proxy);
RestTemplate restTemplate = new RestTemplate(requestFactory);
String url = new String("https://api.github.com/repos/XXX/MyApplication/git/refs/heads/XXX");
Map<String, String> req = new HashMap<String,String>();
req.put("sha", "9a7fd370e28ea7a4bc8242e7f234s5ed07042cb88");
String jsonObject = JSONParser.quote(payload);
HttpEntity<Object> httpEntity = new HttpEntity<>(headers1);
restTemplate.exchange(url, HttpMethod.POST,httpEntity,Object.class);
}

Using the below POST API, I get '404 not found error'.
Method : POST
URL : https://api.github.com/repos/{:user}/{:repo}/git/refs/heads/{:branchname}
{
"sha": "{:new-commit-sha}"
}
Can you any one provide sample Spring RestTemplate implementation for above api?
i found issue in above scenario. for this above POST client userId and password in Headers and it is wrong.
we need to provide userId and Password in BasicAutherizationInceptors class like below.
resttemplate.getInterceptors().add(new BasicAutherizationInterceptor(userId,Pwd));

I tried to call oauth 2 using Spring RestTemplate but ended up with this error 404 Not Found: [{"message":"no Route matched with those values"}]
below is my code .OauthRequest is class created by me .
String oauthurl = serverurl + GET_TOKEN;
HttpHeaders headers = buildHeader();
OauthRequest oathRequest = new OauthRequest();
oathRequest.setClient_id(clientid);
oathRequest.setClient_secret(clientsecret);
oathRequest.setAuthenticated_userid(usercode);
oathRequest.setScope(scope);
oathRequest.setGrant_type(grantTypePassword);
oathRequest.setProvision_key(key);
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Host", hostname);
headers.set("Accept-Version", "1.0");
headers.set("Content-Length", MAX_TRANSFER_SIZE);
HttpEntity<OauthRequest> requestEntity = new HttpEntity<>(oathRequest, headers);
ResponseEntity<OauthResponse> result = restTemplate.exchange(oauthurl, HttpMethod.POST, requestEntity,
OauthResponse.class);
return result.getBody();
Is there any limitation on calling from RestTemplate rather than using OAuth2RestTemplate .My understanding is it will be achievable using RestTemplate also.Must i use OAuth2RestTemplate ?Any help?
RestTemplate does not set hostname in
headers.set("Host", hostname);
Adding below it worked
System.setProperty("sun.net.http.allowRestrictedHeaders", "true");
Please don't mistake it as already asked question. The main difference here is, this issue is coming in Get method call. All the solutions discussed here or other places talks about either POST method or multipart form data.
Configuration I have provided is as below:
String url = env.getProperty(ApplicationConstants.PMCC_MANAGER_REGION_QUERY_URL);
UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url).queryParam("inTIS_PMA_NUMBER","ALL");
URI uri = builder.build().toUri();
RestTemplate restTemplate = getRestTemplateBuilder().build();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<String> response = restTemplate.exchange(uri, HttpMethod.GET, entity, String.class);
private RestTemplateBuilder getRestTemplateBuilder() {
Integer connectionTimeOut = 2000;
Integer readTimeOut = 3000;
RestTemplateBuilder restTemplateBuilder = new RestTemplateBuilder();
restTemplateBuilder.setConnectTimeout(connectionTimeOut);
restTemplateBuilder.setReadTimeout(readTimeOut);
SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
factory.setBufferRequestBody(false);
restTemplateBuilder.requestFactory(factory);
return restTemplateBuilder;
}
This code is part of Spring Boot application and deployed in WebLogic server.
Below is my spring boot code snippet to post json data to server url every few min to tell that I am alive and running(which loads my json input data to db). purpose of this post request is to update the status on application monitoring tool.
What could be the right approach to implment this behaviour in my spring boot app? Is their any decorator api to do such post request to url, every few miuntes through out the application.? how can I know the time of successful post request to do next post request ? Please help me. Thanks in advance.
RestTemplate restTemplate = new RestTemplate();
String url = "endpoint url";
String requestJson = "{\"I am alive\":\"App name?\"}";
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> entity = new HttpEntity<String>(requestJson,headers);
String answer = restTemplate.postForObject(url, entity, String.class);
System.out.println(answer);
Why don't you use the #Scheduled annotation? This will seutes.nd your REST request every 3 minutes...
#Component
public class Heartbeater {
#Scheduled(fixedDelay = 180000)
public void heartbeat() {
// Your code is below...
RestTemplate restTemplate = new RestTemplate();
String url = "endpoint url";
String requestJson = "{\"I am alive\":\"App name?\"}";
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> entity = new HttpEntity<String>(requestJson,headers);
String answer = restTemplate.postForObject(url, entity, String.class);
System.out.println(answer);
}
Background
I am trying to consume a REST endpoint hosted on IBM Cloud API from my SpringBoot application using RestTemplate. I am using the following snippet to make the call:
RestTemplate send = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.setCacheControl(CacheControl.noCache());
headers.set("x-ibm-client-id", clientId);
headers.set("x-ibm-client-secret", clientSecret);
HttpEntity<BodyEntity> httpEntity = new HttpEntity<>(bodyEntity, headers);
send.exchange(ENDPOINT_URL, HttpMethod.POST, httpEntity, Object.class);
I used the following snippet to configure RestTemplate
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
Problem
Using this snippet, when the call is made I receive 401 Unauthorized. When I made the same call using Postman, I received correct response from server without any problem.
Since I received 401 response code I set to further investigate the request by logging headers and body and other parts of request.
I implemented ClientHttpRequestInterceptor to log outgoing requests to further debug the issue and added this interceptor to my RestTemplate config as follows:
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
// new code
builder.interceptors(new LoggingClientHttpRequestInterceptor());
return builder.build();
}
After making the request again, I could see in the log that the outgoing call contained all details as it should e.g. Headers and Body were correct.
After this, I changed the whole thing to use Apache HTTP Client as follows:
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost(URL);
String reqString = "BODY";
httpPost.setEntity(new StringEntity(reqString, ContentType.APPLICATION_JSON));
httpPost.setHeader("accept", "application/json");
httpPost.setHeader("content-type", "application/json");
httpPost.setHeader("cache-control", "no-cache");
httpPost.setHeader("x-ibm-client-id", clientId);
httpPost.setHeader("x-ibm-client-secret", clientSecret);
CloseableHttpResponse response = httpClient.execute(httpPost);
try {
System.out.println("Response status: " + response.getStatusLine());
HttpEntity entity1 = response.getEntity();
System.out.println("Response :" + entity1.toString());
} finally {
response.close();
}
Using the snippet above, I executed the request and received correct response.
Question
Why RestTemplate call returns and error whereas HttpClient returns correct response?
Do I need to further configure RestTemplate?
What have I missed?
I am using Spring Rest Template inside a Spring Boot Application.
I always get 401 Unauthorized error even though I am passing the credentials.
I am able to access this service by Chrome REST Web Service Client.
Is there a simplified way to access the REST template in SpringBoot.
Below is the code snippet done so far which results in 401 error
private DetailsBean invokeDetailsRestService(UserParam userParam){
ResponseEntity<DetailsBean> responseEntity = null;
String url = "https://dev.com/app/identifyuser/";
RestClientConfig restClientConfig =new RestClientConfig("user123","pass123");
responseEntity= restClientConfig.postForEntity(url, userParam, DetailsBean.class);
log.debug("User Details : {} ", responseEntity.getBody());
return responseEntity.getBody();
}
public ClientHttpRequestFactory getRequestFactory(String userName,String password){
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials( new AuthScope(null, -1), new UsernamePasswordCredentials(userName,password) );
HttpClient httpClient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
return new HttpComponentsClientHttpRequestFactory(httpClient);
}
RestClientConfig class
public RestClientConfig(String username, String password) {
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope(null, -1),
new UsernamePasswordCredentials(username, password));
HttpClient httpClient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
setRequestFactory(new HttpComponentsClientHttpRequestFactory(httpClient));
}
Error:
WARN c7af55b5-1cac-4db6-a202-202416c27ba4
12612 --- [apr-8082-exec-8] o.a.http.impl.auth.HttpAuthenticator
: NEGOTIATE authentication error:
No valid credentials provided (Mechanism level:
No valid credentials provided (Mechanism level:
Failed to find any Kerberos tgt))
The authorization issue was fixed with the below code..
Credentials should be passed to a Spring REST Template with the below code:
String userAndPass = "Test:Test123";
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_XML);
headers.add("Authorization", "Basic " + Base64Utility.encode(userAndPass.getBytes()));
I faced similar issue when i'm trying to make call to webservice, this solved my issue:
restTemplate.getInterceptors().add(new BasicAuthorizationInterceptor("userName", "password"));
restTemplate.postForObject('','',''');
Pass the credentials like this, it should solve the issue.
I used spring boot 2.2.4.RELEASE version. then I work below way.
RestTemplate restTemplate = new RestTemplate();
restTemplate.getInterceptors().add(new BasicAuthenticationInterceptor(username, password));
RequestDto requestDto = new RequestDto();
// set parameter
ResponseDto response = restTemplate.postForObject(URL, requestDto, ResponseDto.class);
Or
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setBasicAuth(username, password);
RequestDto requestDto = new RequestDto();
// set parameter
HttpEntity<RequestDto> request = new HttpEntity<>(requestDto, headers);
ResponseDto response = restTemplate.postForObject(URL, request, ResponseDto.class);
