AuthorizationCodeInstalledApp-Android替代

问题描述

[我正在尝试通过Android向Google Oauth进行身份验证，我成功地进行了身份验证，存储了我的凭据和auth令牌，但是有一段特定的代码可供我参考；返回AuthorizationCodeInstalledApp的实例。问题似乎是此API是为Java桌面应用程序制作的，并且正在尝试加载浏览器实例。这是我的GoogleCredentialsUtilityModule，这是Android开发人员文档中显示的代码的稍微重构的版本：

    }

    private fun getCredentials(HTTP_TRANSPORT: NetHttpTransport): Credential {

        val inputStream: InputStream = getCredentialsAsInputStream()
        val clientSecrets: GoogleClientSecrets = GoogleClientSecrets.load(JSON_FACTORY, InputStreamReader(inputStream))

        createTokenFolderIfMissing()

        val authorisationFlow: GoogleAuthorizationCodeFlow = getAuthorisationFlow(HTTP_TRANSPORT, clientSecrets)
        val receiver: LocalServerReceiver = LocalServerReceiver.Builder()
            .setPort(8888)
            .build()

        return AuthorizationCodeInstalledApp(authorisationFlow, receiver).authorize("user") //falls over here
    }

    /**
     * Gets the /credentials.json file
     * @return InputStream
     */
    private fun getCredentialsAsInputStream(): InputStream {
        return this.javaClass.getResourceAsStream(CREDENTIALS_FILE_PATH)
            ?: throw FileNotFoundException("Resource Not found: $CREDENTIALS_FILE_PATH")
    }

    /**
     * Creates the Tokens Folder for Google Authentication
     * Uses the current context for the folder path from
     * Context.getExternalFilesDir()
     */
    private fun createTokenFolderIfMissing() {
        val tokenFolder = getTokenFolder()
        if (!tokenFolder.exists()) {
            tokenFolder.mkdir()
        }
    }

    /**
     * gets External storage directory from the
     * current context
     * @return File
     */
    private fun getTokenFolder(): File {
        return File(this.context.getExternalFilesDir("")?.absolutePath + TOKENS_DIRECTORY_PATH)
    }

    /**
     * Gets authorisation flow so that the application can authenticate into Google Calendars
     * @param HTTP_TRANSPORT allows the app to use HTTP connections
     * @param clientSecrets secrets for authentication into Google
     * @return GoogleAuthorizationCodeFlow
     */
    private fun getAuthorisationFlow(HTTP_TRANSPORT: NetHttpTransport, clientSecrets: GoogleClientSecrets): GoogleAuthorizationCodeFlow {
        return GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
            .setDataStoreFactory(FileDataStoreFactory(getTokenFolder()))
            .setAccessType("offline")
            .build()
    }
}

这是我的错误消息：

我似乎找不到AuthorizationCodeInstalledApp的任何替代方法。有什么建议吗？我应该编写自己的身份验证代码吗？我可以使用Android版本的AuthorizationCodeInstalledApp吗？我发现文档如此含糊且难以阅读。

[使用Google Pixel 3 XL在API 29上进行开发。

思路：

嗯-看起来您正在端口8888上运行回送Web服务器，它比移动解决方案更像是台式机解决方案。

通过Chrome自定义标签并使用Google AppAuth库登录，您可能会获得更加用户友好和可靠的解决方案。不过，这并不容易。

也许看看我的Tutorial + Code Sample，至少可以给您一些比较的东西。
