Problem with URL Encoding in Login

[BssdTS]

Hi,

when providing credentials as a body, e.g.
{
"jwtusername": "test@test.com",
"jwtpassword": "te6,w~JcYxWsO%SH281R9G~N@*AQv&,W"
}
TMVCJWTAuthenticationMiddleware.OnBeforeRouting tries to parse the username and password by calling

LUsername := AContext.Request.ContentParam(FUserNameHeaderName);
LPassword := AContext.Request.ContentParam(FPasswordHeaderName);

before actually parsing the request body as a JSON. The ContentParam function attempts to URL Decode the params, which will fail with the given example (password). You would have to URL Encode the content of this JSON, to not have the conversion error be raised, which is inconsistent with other routes that have a JSON body.

We propose changing the above code to

LUsername := AContext.Request.QueryStringParam(FUserNameHeaderName);
LPassword := AContext.Request.QueryStringParam(FPasswordHeaderName)

which will correctly parse the credentials exclusively from query parameters.
Parsing the JSON content at this point is not necessary, because this code is followed by a dedicated JSON body parsing routine.

Hope you find this useful :)
