Error 411 Google Drive for getting an access token and a refresh token after authorization

[Laurent Thulier]

Hey everybody, (Sorry if my english is not perfect yet)

I'm usering Jersey for REST methods in Java. I can authorize the user to accept an app, it returns me a code...

but when I want to get the access token and the refresh token with my code, an error occurs.. I don't know why, it's all the time error 411 length required

I tried many things to set the length but nothing works... I don't know if it's another problem than this.

I tried to delete the \n after pasting the code... I put a lot of things in comment to see my historic, what I tried to make it work.

Anyone Could Help me pleaaase?

This is my code:

private static String urlToken_="https://accounts.google.com/o/oauth2/token HTTP/1.1";

//get access token

try 

{

//write the code 

System.out.println("Write  code :");

Scanner sc = new Scanner(System.in);

String authorizationCode=sc.nextLine();

authorizationCode=authorizationCode.replace("\\n", "");

//authorizationCode.replace(".", "");

urlToken_=urlToken_.replace(" ", "%20");

WebResource resource2=c.resource(urlToken_);

// resource2.setProperty("Host", "accounts.google.com");

// resource2.setProperty("Content-Type", "application/x-www-form-urlencoded");

// resource2.setProperty("Content-Length", authorizationCode.length());

//resource2.accept("application/x-www-form-urlencoded");

//build path for getting access token and secret access token

//resource2.header("Content-Length", "0");

// resource2.entity(resource.header("Host","accounts.google.com"));

// resource2.entity(resource.header("Content-Type","application/x-www-form-urlencoded"));

// resource2.entity(resource.header("Content-Length","0"));

//construction of url with parameters

//

// OAuthParameters params = new OAuthParameters().consumerKey(clientID_);

// OAuthSecrets secrets = new OAuthSecrets().consumerSecret(clientSecret_);

//

// OAuthClientFilter filtre=new OAuthClientFilter(c.getProviders(), params, secrets);

// resource2.addFilter(filtre);

MultivaluedMap<String,String> query=new MultivaluedMapImpl();

query.add("code",authorizationCode);

query.add("client_id",clientID_);

query.add("client_secret",clientSecret_);

query.add("redirect_uri",redirectURI_);

query.add("grant_type","authorization_code");

query.add("access_type", "offline");

OAuthParameters params = new OAuthParameters().consumerKey(clientID_);

//String cr=resource2.queryParams(query).header("Content-Type", "application/x-www-form-urlencoded").post(String.class);

//String cr=resource2.queryParams(query).header("content-length", 0).post(String.class);

//String cr=resource2.queryParams(query).header("Content-Type", "application/x-www-form-urlencoded").header("Content-Length","0").post(String.class);

//String cr=resource2.queryParams(query).header("Content-Type", "application/x-www-form-urlencoded").header("Host", "accounts.google.com").header("Content-Length",HttpHeaders.CONTENT_LENGTH).post(String.class);

//String cr=resource2.queryParams(query).header("Content-Type", "application/x-www-form-urlencoded").header("Host", "accounts.google.com").header("Content-Length",resource2.toString().length()).post(String.class);

String cr=resource2.queryParams(query).post(String.class);

//String cr=resource2.queryParams(query);

System.out.println(cr);

}

catch(Exception ex)

{

System.out.println(ex.toString());
