Question

Screenshot of smartsheet and google setup screens

当尝试从Smartsheet中获取数据时，我遇到一条错误，该错误是当我遵循由我的应用程序脚本项目记录的链接时，重定向URI丢失或无效。

我已经在Google和Smartsheet上生成了一个客户端ID和客户端密码，但我不知道下一步该怎么做。

Google凭据：我不确定要在下面的链接中将“重定向URL”部分或授权的Java代码来源放入什么内容。

https://console.developers.google.com/apis/credentials/oauthclient/########################2d.apps.googleusercontent.com?project=project-id-##############

智能表凭据：我已经激活了Smartsheet Developer个人资料，并为我称为“ Google表格”的应用生成了客户端ID和客户端密码。

下面显示的是我现在在gitHub上找到的代码。

var CLIENT_ID = '...'; // what do I put here?
var CLIENT_SECRET = '...';  // what do I put here?

Answer 1

我对您使用的Apps脚本或库了解不多，但是您需要查找Apps脚本使用的实际回调URI，并将其注册为Smartsheet中的App Redirect URL。看起来回调应该采用https://script.google.com/macros/d/{SCRIPT ID}/usercallback的形式（至少根据库文档）。那应该发出重定向，该重定向最终将使用令牌的授权代码调用您的库authCallback。

这是该过程的另一个有用的文档（但使用Node）。 https://developers.smartsheet.com/blog/creating-a-smartsheet-o-auth-flow-in-node-js

Answer 2

这是一个非常复杂的过程，我已经在此处进行了记录：https://smartsheet-platform.github.io/api-docs/#third-party-app-development

如果在阅读本文档/教程部分后仍有疑问，请继续询问。我在这里为您提供帮助。
