Answer 1

解决了它，以下是对我有效的：

请检查您的Mongodb Atlas prod数据库的用户/密码是否与您在Heroku中设置的MONGO_URI变量正确匹配，这是导致我出现此问题的原因。我认为这里很容易出现错别字，因为在创建数据库用户密码后，您无法看到该用户的密码。还要注意，用户不应该是“只读”的，而且这与登录Mongodb Atlas时使用的用户/密码组合不同。

我发现身份验证回调失败并出现超时错误的原因是文件passport.js中定义的Google策略的回调从未调用方法done（）。这反过来是因为在MongoDB中查找用户的查询从未完成，因为Mongoose无法连接到mlab.com数据库。我尝试在mlab中为prod数据库创建一个新用户，并在Heroku环境变量中更新该用户，它成功了！
