[ORCID API]Use java httpclient to get Access Token

[mayh]

Hi,

 I'd write a thin program base on java to integrate our library site.

 But on the first step, I got the error message "{"error":"unauthorized","error_description":"An Authentication object was not  found in the SecurityContext"}. "

 What's wrong with me?  Here is my code.


            DefaultHttpClient httpclient = new DefaultHttpClient();            
            HttpContext httpContext = new BasicHttpContext();
            this.cookieStore = new BasicCookieStore();
            httpContext.setAttribute(ClientContext.COOKIE_STORE, this.cookieStore);
           
            HttpPost httppost = new HttpPost("http://api.sandbox-1.orcid.org/oauth/token");
            httppost.addHeader("Accept","application/json");
            java.util.List <NameValuePair> nvps = new ArrayList <NameValuePair>();
            nvps.add(new BasicNameValuePair("client_id", clientId));
            nvps.add(new BasicNameValuePair("client_secret", secret));
            nvps.add(new BasicNameValuePair("scope", "/read-public"));
            nvps.add(new BasicNameValuePair("grant_type", "client_credentials"));
            StringEntity stringentity = new StringEntity(URLEncodedUtils.format(nvps, "UTF-8"));
            httppost.setEntity(stringentity);

            String result = EntityUtils.toString(httpclient.execute(httppost,httpContext).getEntity(),"UTF-8");  // Just print out the result.

Hi Shun-hong,

That error looks the same as not posting a form.

curl -i -v -H 'Accept: application/json' -d 'client_id=0000-0002-9353-5519&client_secret=1470a572-1e0d-4e7d-899a-c9eafca4e05d&scope=/read-public&grant_type=client_credentials' 'http://api.sandbox-1.orcid.org/oauth/token'

vs

curl -i -L -H 'Accept: application/json' 'http://api.sandbox-1.orcid.org/oauth/token'

Looking at https://hc.apache.org/httpcomponents-client-ga/quickstart.html I would be temped use UrlEncodedFormEntity, but that would just be a guess.

Cheers,
Rob

Hi,

I encountered this error too. It was because of missing form parameters. Eventhough I had all the listed params, somehow it was not getting posted to orcid.

 I made it work using org.apache.http.client.methods.HttpPost and org.apache.http.NameValuePair

Thanks

Suman

Thank you,

Hi, Suman
 
 Did you solve this problem? I'd follow the guide by put all need parameters, even try to simulate the cURL agent header.

 But it's still no work.

Hi Mayh,

Maybe you should try a different library.  Using ClientResource from Restlet looks nice:

https://github.com/TomDemeranville/orcid-java-client/blob/master/src/main/java/uk/bl/odin/orcid/client/OrcidOAuthClient.java

You might also decide to use Tom's client as it looks quite nice.

Cheers,
Rob

[Suman Upadhyay]

Yes mayh

I was able to connect to orcid from my application using the libraries i mentioned before. Right now we are only building a service to get back orcid id. Let me know if you have anymore question.

Hi, Suman

 Because of  I want to  make our Web-Site simple with don't include too many framework.

 I prefer to write a new one. It was success when I change the library to newest Apache http-client library.

The library as a whole is really easy to use.  It'll handle the OAuth part, generate auth requests and turning authcodes into tokens.  It'll handle search, profile reads and updating works.  Adding other calls to the API should be really easy.  Oh, and it can be added with Maven.  See https://github.com/TomDemeranville/orcid-java-client for docs and maven instructions.

Turning an auth code into a token is as simple as creating a client using your credentials and calling a method.

OrcidOAuthClient client = new OrcidOAuthClient("OrcidClientID","OrcidClientSecret",("OrcidReturnURI"),useSandbox);
OrcidAccessTokenResponse token = client.getAccessToken(authCode);

What are you trying to achieve?  I could probably add the call to the library.

Tom.

Hi all, and sorry for my english :P

I had the same problem, with java.net.* (HttpURLConnection for example) doesnt work, but (like someone here said) with apache HttpComponents (Http Client 4.3) works fine --> http://hc.apache.org/httpcomponents-client-4.3.x/index.html 

For download the jar: http://hc.apache.org/httpcomponents-client-4.3.x/download.html

A example of implementation for adquire a ORICD with a correct Code will be:

You will need these imports:

import org.apache.http.*;

import org.apache.http.client.methods.*;

import org.apache.http.impl.client.*;

import org.apache.http.util.*;

import org.apache.http.message.*;

import org.apache.http.client.entity.*;

the implementation (with json simple for the response https://code.google.com/p/json-simple/):

 

CloseableHttpClient httpclient = HttpClients.createDefault();

HttpPost hp=new HttpPost(url_token);

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);

 

nameValuePairs.add(new BasicNameValuePair("client_id", client_id)); 

nameValuePairs.add(new BasicNameValuePair("client_secret", client_secret));

        nameValuePairs.add(new BasicNameValuePair("grant_type", "authorization_code"));  

nameValuePairs.add(new BasicNameValuePair("code", code)); 

        nameValuePairs.add(new BasicNameValuePair("redirect_uri",url_response )); 

        hp.setEntity(new UrlEncodedFormEntity(nameValuePairs));    

        

        HttpResponse response = httpclient.execute(hp);         

    

        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        String line = "";   

        

        JSONParser parser=new JSONParser();         

        if ((line = rd.readLine()) != null) {

          //This line is the json response of the server :)

        System.out.println(line);

         

        Object obj = parser.parse(line);

        JSONObject obj2 = (JSONObject)obj;

         

           

            System.out.println("access_token:"+obj2.get("access_token"));

            System.out.println("token_type:"+obj2.get("token_type"));

            System.out.println("efresh_token:"+obj2.get("efresh_token"));

            System.out.println("expires_in:"+obj2.get("expires_in"));

            System.out.println("scope:"+obj2.get("scope"));

            System.out.println("orcid:"+obj2.get("orcid"));

            orcid=(String)obj2.get("orcid");

             

        

            

        }

Regards!;

I don't want to muddy the waters here, but I am using HttpURLConnection to get the OAuth token.

Cheers,

Sidney
