Question

我正在研究在tomcat上运行的Spring-MVC应用程序，我想在其中使用Google驱动器功能。我尝试使用本地计算机上的服务帐户，我没有遇到任何问题。但是当我在服务器上上传代码时，浏览器URL不会被打开。然后我想，我不应该使用服务帐户，我应该使用普通的网络应用程序帐户。现在，当我这样做时，我得到一个redirect_uri_mismatch。

我不明白一件事，我在流程中设置重定向网址，在JSON中，为什么它会获得带有随机端口号的redirect_url。如果我更改浏览器URL中的端口号，它可以正常工作。但仍然在服务器上它不会打开浏览器URL，我可以在tomcat日志中看到它，但该死的东西不会打开URL。

以下是我在Google应用中的重定向网址：

http://localhost/authorizeuser
http://localhost:8080/
http://localhost:8080
http://localhost
http://localhost:8080/Callback
https://testserver.net/Callback
http://testserver.net/Callback
http://127.0.0.1

这是我的client_secret.json：

{"web": {
    "client_id": "clientid",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_email": "clientemailstuff",
    "client_x509_cert_url": "certurlstuff",
    "client_secret": "itsasecret",
    "redirect_uris": ["http://localhost:8080/","http://localhost:8080"],
    "javascript_origins": ["https://testserver.net", "http://testserver.net","http://localhost:8080"]
}}

以下是我要验证的代码：

 @Override
    public Credential authorize() throws IOException {
        InputStream in =
                DriveQuickstartImpl.class.getResourceAsStream("/client_secret.json");
        GoogleClientSecrets clientSecrets =
                GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

        GoogleAuthorizationCodeFlow flow =
                new GoogleAuthorizationCodeFlow.Builder(
                        HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
                        .setDataStoreFactory(DATA_STORE_FACTORY)
                        .setAccessType("offline")
                        .build();
        flow.newAuthorizationUrl().setState("xyz").setRedirectUri("http://localhost:8080/Callback");
        Credential credential = new AuthorizationCodeInstalledApp(
                flow, new LocalServerReceiver()).authorize("user");

        if(credential!=null && credential.getRefreshToken() != null){
            storeCredentials(credential);
        }
        return credential;
    }

当我设置重定向网址时，这主要是在惹恼我，它只是被忽略了，为什么在服务器上部署应用程序时，浏览器选项卡不会被打开。

更新 Spring问题也解决了，下面的代码可以用于tomcat或其他服务器上的GoogleDrive授权。

@Service
@Transactional
public class GoogleAuthorization{


    @Autowired
    private DriveQuickstart driveQuickstart;

    private static final String APPLICATION_NAME ="APPNAME";

    private static final java.io.File DATA_STORE_DIR = new java.io.File(
            "/home/deploy/store");

    private static FileDataStoreFactory DATA_STORE_FACTORY;

    private static final JsonFactory JSON_FACTORY =
            JacksonFactory.getDefaultInstance();

    private static HttpTransport HTTP_TRANSPORT;

    private static final List<String> SCOPES =
            Arrays.asList(DriveScopes.DRIVE);

    private static final String clientid = "clientid";
    private static final String clientsecret = "clientsecret";

    private static final String CALLBACK_URI = "http://localhost:8080/getgooglelogin";

    private String stateToken;

    private final GoogleAuthorizationCodeFlow flow;

    public GoogleAuthorization(){
        try {
            HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
            DATA_STORE_FACTORY = new FileDataStoreFactory(DATA_STORE_DIR);

        } catch (GeneralSecurityException | IOException e) {
            e.printStackTrace();
        }

        flow = new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT,
                JSON_FACTORY, clientid, clientsecret, SCOPES).setAccessType("offline").setApprovalPrompt("force").build();
        generateStateToken();

    }



    /**
     * Builds a login URL based on client ID, secret, callback URI, and scope
     */
    public String buildLoginUrl() {

        final GoogleAuthorizationCodeRequestUrl url = flow.newAuthorizationUrl();

        return url.setRedirectUri(CALLBACK_URI).setState(stateToken).build();
    }

    /**
     * Generates a secure state token
     */
    private void generateStateToken(){
        SecureRandom sr1 = new SecureRandom();
        stateToken = "google;"+sr1.nextInt();
    }

    /**s
     * Accessor for state token
     */
    public String getStateToken(){
        return stateToken;
    }

    /**
     * Expects an Authentication Code, and makes an authenticated request for the user's profile information
     * * @param authCode authentication code provided by google
     */
    public void saveCredentials(final String authCode) throws IOException {

        GoogleTokenResponse response = flow.newTokenRequest(authCode).setRedirectUri(CALLBACK_URI).execute();
        Credential credential = flow.createAndStoreCredential(response, null);
        System.out.println(" Credential access token is "+credential.getAccessToken());
        System.out.println("Credential refresh token is "+credential.getRefreshToken());
// The line below gives me a NPE.
        this.driveQuickstart.storeCredentials(credential);
    }
}

控制器方法：

  @RequestMapping(value = "/getgooglelogin")
    public String getGoogleLogin(HttpServletRequest request, HttpServletResponse response, HttpSession session,Model model) {
// Below guy should be autowired if you want to use Spring. 
        GoogleAuthorization helper = new GoogleAuthorization();

        if (request.getParameter("code") == null
                || request.getParameter("state") == null) {

            model.addAttribute("URL", helper.buildLoginUrl());
            session.setAttribute("state", helper.getStateToken());

        } else if (request.getParameter("code") != null && request.getParameter("state") != null && request.getParameter("state").equals(session.getAttribute("state"))) {
            session.removeAttribute("state");

            try {
                helper.saveCredentials(request.getParameter("code"));
                return "redirect:/dashboard";
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return "newjsp";
    }

newjsp只有一个点击URL的按钮。

Answer 1

具体而言，您获取随机端口是因为您使用的是LocalServerReceiver starts up a jetty instance on a free port，以便接收验证码。

在更高级别，看起来您正在开发web server application，但您尝试使用Google OAuth，就好像它是installed application一样。如果您确实在制作Web服务器应用程序，则应该在回调URL中使用服务器的主机名而不是localhost，为最终用户提供使用flow.newAuthorizationUrl()进行身份验证的链接，并进行回调使用flow.newTokenRequest(String)获取令牌。另外，请确保您在console中创建的客户ID属于Web应用程序类型，或者您是get redirect_uri_mismatch errors。可以找到here的完整工作示例。

而不是使用：

Credential credential = new AuthorizationCodeInstalledApp( flow, 
                     new LocalServerReceiver).authorize("user");

使用

LocalServerReceiver localReceiver = new LocalServerReceiver.
                                        Builder().setPort(XXXX).build();

用于设置静态端口号

Credential credential = new AuthorizationCodeInstalledApp( flow,
                                      localReceiver).authorize("user");

虽然您无法更改重定向网址，但您可以设置主机和端口。用于更改主机使用.setHost()方法

您也可以使用默认构造函数：

Credential credential = new AuthorizationCodeInstalledApp( flow, 
             new LocalServerReceiver("Host", XXXX).authorize("user");

Spring：Google身份验证redirect_uri_mismatch和URL无法在浏览器上打开
