google-api - 如何使用谷歌 API 为 1 小时购物提要生成刷新/访问令牌

Question

我正在使用 Google API 生成访问令牌，但这个Google 视频说令牌将在 1 小时后过期。目前，令牌在 4-5 秒后过期。

如何生成一个 1 小时的令牌或增加令牌的到期时间我也在使用谷歌的授权流程，比如使用谷歌签名并获得一次访问令牌，但是当我发出另一个请求时，令牌就会过期。

所以请提供有价值的反馈。

这是身份验证谷歌内容api的链接 - https://developers.google.com/shopping-content/guides/how-tos/authorizing 如果你只想要访问令牌，你可以这样做 - tokenResponse.getAccessToken()，它正在工作1 小时，您必须设置 clientId、clientSecret、redirectUri 和 Scope。

  val jsonFactory: JsonFactory = JacksonFactory.getDefaultInstance

  import com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets.Details

  val details = new Details

  // Authorize the OAuth2 token.// Authorize the OAuth2 token.

  val tokenRequest: GoogleAuthorizationCodeTokenRequest =
    authorizationFlow.newTokenRequest(authorizationCode)
  tokenRequest.setRedirectUri(redirectUrl)
  println(s"token Request - $tokenRequest")
  val tokenResponse: GoogleTokenResponse = tokenRequest.execute()
  println(s"token response - $tokenResponse")

  // Create the OAuth2 credential.
  val credential: GoogleCredential = new GoogleCredential.Builder()
    .setTransport(new NetHttpTransport())
    .setJsonFactory(new JacksonFactory())
    .setClientSecrets(clientSecrets)
    .build()

  // Set authorized credentials.
  credential.setFromTokenResponse(tokenResponse)

  val service: ShoppingContent = new ShoppingContent.Builder(httpTransport, jsonFactory, credential)
    .setApplicationName("")
