doc: specify event uri and streaming uri (#9)

* Added EventUri and StreamingUri params in Dependency Injection Code Example

The first time I tried dependency injection without these two configurations, it gave me no warning, it just did not work.

I only found the error by examining the log.

So I think it's much better to add these two variables to the sample code. For better UX
