View Source in Chrome sends another request for the file, and since it's not authenticated, it returns the source of the login page. This is different from the way say IE works, where the source is cached and returned when you try to view it.
Inspect Element shows the current DOM's snapshot data. This is what you got from making your initial, authenticated request. So yes, this is the "correct" one.
根据回复，以我们在 Inspect Element 里看到的为准。
