Question

我正在使用Jersey客户端调用Google oauth作为令牌，如下所示。

ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
WebResource webResource = client.resource(UriBuilder.fromUri("https://accounts.google.com/o/oauth2/token").build());
MultivaluedMap formData = new MultivaluedMapImpl();
formData.add("code", request.getParameter("code"));
formData.add("client_id", Global.GOOGLE_CLIENT_ID);
formData.add("redirect_uri", Global.GOOGLE_REDIRECT_URL);
formData.add("client_secret", Global.GOOGLE_SECRET);
formData.add("grant_type", "authorization_code");
ClientResponse response1 = webResource.type(MediaType.APPLICATION_FORM_URLENCODED_TYPE).post(ClientResponse.class, formData);
System.out.println(response1.getEntity(String.class));
System.out.println(response1.getClass().getName());

我得到的回应

{“access_token”：   “ya29.nQCXFIhTs8s-SQKON6NjPv7wkBcJxlasdlkjsdsklsGuzMMqyDz3XpkNLT”，
  “token_type”：“Bearer”，“expires_in”：3599，“id_token”：   “eyJhbGciOiJSUzI1NiIsImtpZCI6IjdkZGQwOGEwM2IyNWQwZjVhMDllMjNiMmJlMTBkZDIyODQyYTg1NjkifQ.eyJpc3MiOiJhY2NvdW50csdlksjdsdkljdslkjdsdslkjdjsdkljjsldkjsdj987230iOiJwcmVtMXByZUBnbWFpbC5jb20iLCJhdF9oYXNoIjoiMmt2RlZ1RUpTMGp4UWlIUDgtckVuZyIsImVtYWlsX3ZlcmlmaWVkIjp0cnVlLCJhdWQiOiI1OTQ5NTUyODE4ODYtYnFyMGRibWRyYWJxYW9ubWhlaXFrMHNrZGRmNWFsazUuYXBwcy5nb29nbGV1c2VyY29udGVudC5jb20iLCJpYXQiOjE0MTMyMTQ4ODIsImV4cCI6MTQxMzIxODc4Mn0.pc2Snmb4pRF_TqylBuEpz0oBoWZsIq-_r_sqLS06E6DJKgSawWCg_3vqtI72GvWno0J8UghZka6rpaoAFo5RZlxNxLDs4GV5rZqdodNgbKjEO-5MrpGZWUOM7SNoYooASesmTtbamDoCf6G74MSKW5XKaVwdvFEUsSBz5NuavNU”}

如何从响应中获取id_token并在响应中获取实际值。

Answer 1

迄今为止实现的最简单的解决方案是使用JSONSerializer来获取字符串响应的JSONObject表示。代码看起来与此类似：

JSONObject jsonOutput = (JSONObject) JSONSerializer.toJSON( response.getEntity(String.class) ); 
String access_token = jsonOutput.getString("access_token");
String id_token = jsonOutput.getString("id_token");

我建议使用google java客户端拨打电话：https://code.google.com/p/google-api-java-client/wiki/OAuth2

使用GoogleAuthorizationCodeTokenRequest类，您可以直接取回GoogleResponseToken而无需担心JSON。示例如下：http://javadoc.google-api-java-client.googlecode.com/hg/1.18.0-rc/com/google/api/client/googleapis/auth/oauth2/GoogleAuthorizationCodeTokenRequest.html

代码就像这样简单（直接取自链接）：

  GoogleTokenResponse response =
      new GoogleAuthorizationCodeTokenRequest(new NetHttpTransport(), new JacksonFactory(),
          "812741506391.apps.googleusercontent.com", "{client_secret}",
          "4/P7q7W91a-oMsCeLvIaQm6bTrgtp7", "https://oauth2-login-demo.appspot.com/code")
          .execute();
  System.out.println("Access token: " + response.getAccessToken());
  System.out.println("Id token: " + response.getIdToken());
