Support Non-Hash Auth Code Redirects

[chrisguitarguy]

Expected Behavior

I can handled an auth code redirect with a query string, not just a hash.

[REQUIRED] Describe expected behavior

When I call completeAuthorizationRequestIfPossible i'd like it to look at the query string if some configuration option is set.

This line:

AppAuth-JS/src/redirect_based_handler.ts

Line 100 in c30f85e

let queryParams = this.utils.parse(this.locationLike, true /* use hash */);

it'd be cool if could handle query strings or hashes.

Describe the problem

See above. My oauth server returns query strings, not hashes. Would like to be able to use this library in browser.

[REQUIRED] Actual Behavior

Second half of the oauth flow never completes, since the code, state, etc, are all in the query string, not hash.

[REQUIRED] Steps to reproduce the behavior

Use an oauth server that sends back an auth code response in a query string.

[REQUIRED] Environment

• AppAuth-JS version: 1.3.1
• AppAuth-JS Environment (Node, Browser (UserAgent), ...):Browser
• Source code snippts (inline or JSBin)
