我正在嘗試使用他們的 API 從谷歌表格中提取資料，并且我的代碼在我的本地機器上作業。但是，在 Heroku 中部署它之后，我得到了這個錯誤。這是我在 Heroku 中部署時懷疑失敗的部分代碼。
private static Credential getCredentials(final NetHttpTransport HTTP_TRANSPORT) throws IOException {
InputStream in = ProcessGoogleSheets.class.getResourceAsStream(CREDENTIALS_FINAL_PATH);
if (in == null) {
throw new FileNotFoundException("Resource not found: " CREDENTIALS_FINAL_PATH);
}
GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
.setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
.setAccessType("offline")
.build();
LocalServerReceiver receiver = new LocalServerReceiver.Builder().setPort(8080).build();
return new AuthorizationCodeInstalledApp(flow, receiver).authorize("user");
}
這是 Heroku 回傳的日志。

有什么想法可以解決這個問題嗎？提前致謝。
uj5u.com熱心網友回復：
Address already in use——這里的地址通常是指PORT。
似乎一個應用程式已經Heroku在埠上運行8080，所以嘗試更改埠并重新部署，你應該沒問題。
uj5u.com熱心網友回復：
我在 setPort 中使用了 -1，該值會自動將應用程式連接到未使用的埠。
這是現在有效的代碼。
