Question

我正在尝试使用google people api，但我遇到了很多困难。从api控制台生成的json文件不包含clientSecret。我在哪里可以得到它？所以我得到空授权代码。任何人都可以帮我解决这个问题吗？提前致谢

   public void setUp() throws IOException {
            HttpTransport httpTransport = new NetHttpTransport();
            JacksonFactory jsonFactory = new JacksonFactory();

            // Go to the Google Developers Console, open your application's
            // credentials page, and copy the client ID and client secret.
            // Then paste them into the following code.
            String clientId = "";
            String clientSecret = "";

            // Or your redirect URL for web based applications.
            String redirectUrl = "urn:ietf:wg:oauth:2.0:oob";
            String scope = "https://www.googleapis.com/auth/contacts.readonly";

            // Step 1: Authorize -->
            String authorizationUrl = new GoogleBrowserClientRequestUrl(clientId,
                    redirectUrl,
                    Arrays.asList(scope))
                    .build();

            // Point or redirect your user to the authorizationUrl.
            System.out.println("Go to the following link in your browser:");
            System.out.println(authorizationUrl);

            // Read the authorization code from the standard input stream.
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
            System.out.println("What is the authorization code?");
            String code = in.readLine();

            System.out.println(code);
            // End of Step 1 <--

            // Step 2: Exchange -->
            GoogleTokenResponse tokenResponse = new GoogleAuthorizationCodeTokenRequest(
                    httpTransport, jsonFactory, clientId, clientSecret, code, redirectUrl).execute();
            // End of Step 2 <--

            GoogleCredential credential = new GoogleCredential.Builder()
                    .setTransport(httpTransport)
                    .setJsonFactory(jsonFactory)
                    .setClientSecrets(clientId, clientSecret)
                    .build()
                    .setFromTokenResponse(tokenResponse);

            People peopleService = new People.Builder(httpTransport, jsonFactory, credential)
                    .build();

        }

Answer 1

要获取ClientID和ClientSecret，您应该创建Web应用程序ClientID，并且您需要它。

另一件值得注意的事情是response_type生成的网址中的GoogleBrowserClientRequestUrl将token导致错误。我尝试将response_type更改为code，然后就可以了。

完整网址看起来像

https://accounts.google.com/o/oauth2/auth?client_id=YOUR_ANDROID_APPLICATION_CLIENT_ID&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&scope=https://www.googleapis.com/auth/contacts.readonly

Answer 2

创建客户端ID时，选择“应用程序类型”作为“其他”，然后您可以找到clientSecret。 Screen shot
