PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target #333
Description
I am not fan of Spring RestTemplate yet, but I would like to use the HttpClient API. My following code works fine, but when tried to convert it to HttpClient, it's giving errors
public static void main(String[] args) {
HttpHeaders headers = new HttpHeaders();
headers.add("Accept", "application/json");
//headers.add("Content-Type", "application/x-www-form-urlencoded");
headers.add("Content-Type", MediaType.APPLICATION_FORM_URLENCODED.toString());
headers.add("Authorization", "Basic XXXXXXXXXXXXX");
String url = "https://XXXXXXXXX:8243/token";
String data = "grant_type=password&username=XXXX&password=XXXX";
RestTemplate restTemplate = new RestTemplate();
HttpEntity<String> entity = new HttpEntity<String>(data,headers);
System.out.println("ENTITY : "+entity);
HttpEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, entity, String.class);
System.out.println("RESPONSE : "+response.getBody());
}
But if tried same with HttpClient causing problem. I think data is not getting set properly that's why it's causing proble. DO you know how we can pass data in HttpClient?
public static void main(String[] args) throws ClientProtocolException, IOException {
String url = "https://XXXXXXXXXX:8243/token";
String data = "grant_type=password&username=admin&password=admin";
HttpClient client = HttpClientBuilder.create().build();
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
httpPost.setHeader("Authorization", "Basic XXXXXXXXXXXX");
List<NameValuePair> urlParameters = new ArrayList<NameValuePair>(3);
urlParameters.add(new BasicNameValuePair("grant_type", "password"));
urlParameters.add(new BasicNameValuePair("username", "XXXX"));
urlParameters.add(new BasicNameValuePair("password", "XXXX"));
HttpEntity postParams = new UrlEncodedFormEntity(urlParameters);
httpPost.setEntity(new StringEntity(data));
HttpResponse httpResponse = client.execute(httpPost);
System.out.println(httpResponse);
}
