//Basic Authorization Setting
http_client_config config;
credentials creds(L"name", L"password");
config.set_credentials(creds);
http_client client(U("http://severip/"), config);

// create header
http_request req(methods::GET);

//// Add base64 result to header
req.headers().add(L"Authorization", L"Basic bmFtZTpwYXNzd29yZA");
req.set_request_uri(L"/_cat/master");
pplx::task<http_response> responses = client.request(req);
pplx::task<web::json::value> jvalue = responses.get().extract_json();
web::json::value v = jvalue.get();
utility::string_t jsonval = v.serialize();
wcout << jsonval << endl;

//with base64 encoding.
//bmFtZTpwYXNzd29yZA = name:password

I'm trying to set a credentials through cpprestsdk aka casablanca.

And I've recived 401 error which is failed to athenticate user, it means password error.

Any advice would be thankful.

Try to use the curl command to validate user/password quickly.


curl -X PUT --basic  -u {user}:{password} http://severip/

  • thanks for comments. I know the user/password information. The problem is, my user&password are correct and curl command doing fine, but it spits out 401 error through cpprest-sdk. I think it's from the code problem. Any thoughts? – IC1101Galaxy Feb 05 '20 at 01:50
  • curl -H 'Authorization:Basic bmFtZTpwYXNzd29yZA' -H 'Content-Type: application/json' verify if the base 64 is correct or not. – YouXiang-Wang Feb 05 '20 at 01:59
  • I've got curl: (6) Could not resolve host: bmFtZTpwYXNzd29yZA curl: (6) Could not resolve host: application Does it means my base64 string is not correct? – IC1101Galaxy Feb 05 '20 at 02:05
  • curl http://${severip}/${port}/_cat/master -H 'Authorization:Basic bmFtZTpwYXNzd29yZA' -H 'Content-Type: application/json' – YouXiang-Wang Feb 05 '20 at 02:09
  • {"error":{"root_cause":[{"type":"security_exception","reason":"missing authentication credentials for REST request [/_cat/master]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}}],"type":"security_exception","reason":"missing authentication credentials for REST request [/_cat/master]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}},"status":401}curl: (6) Could not resolve host: bmFtZTpwYXNzd29yZA' curl: (6) Could not resolve host: application – IC1101Galaxy Feb 05 '20 at 02:13
  • No. The error is thrown by elastic-search cluster which I want to sending a query through cpprest-sdk – IC1101Galaxy Feb 05 '20 at 02:19
  • I got my cluster locked with password so I must enter the username and password to connect the cluster. – IC1101Galaxy Feb 05 '20 at 02:22
  • Yes. So if I want to sending a query like this one "curl -XGET http://{serverip:9200}/_cat/master" , I must add athentification option like "curl -XGET http://{serverip:9200}/_cat/master -u name:password" but in elastic-search, name will always static {elastic}. – IC1101Galaxy Feb 05 '20 at 02:52
  • What I want to do is just doing this curl job with athentification {-u elastic:password} through cpprest-sdk. Sending a query with no athentification is just worked fine with no problem. – IC1101Galaxy Feb 05 '20 at 02:56
