为什么在ExecutionContext中无user?

[icemanpro]

在example内的usernameFromContext函数可取到request.user,但在我自己的程序中request.user是未定义的，我想问下，是哪里没设置对？

For the jwt-strategy, Passport first verifies the JWT's signature and decodes the JSON. It then invokes our validate() method passing the decoded JSON as its single parameter. 

Recall again that Passport will build a user object based on the return value of our validate() method, and attach it as a property on the Request object.
