IdentityServer BearerAuthentication from WebApi Mi

问题:

after updating my project to angular 2 final i had a problem getting WebApi2 authoriaztion to work with IdentityServer3 and angular2-jwt. Before everything worked fine when in angular2-jwt configuration the headername was empty and the token-getter-method returned simply the token.

After updating an empty headername caused an javascript-error:

 EXCEPTION: Failed to execute 'setRequestHeader' on 'XMLHttpRequest': '' is not a valid HTTP header field name.

So first i had to provide a headername, in my root-module angular2-jwt config looked like this:

        provideAuth({
        headerName: 'BearerToken',
        headerPrefix: '',
        tokenName: '',
        tokenGetter: () => {
            return JSON.parse(localStorage.getItem('bearerToken'));
        },
        globalHeaders: [{'Content-Type': 'application/json'}],
        noJwtError: true,
        noTokenScheme: true
    })

Still not working. After some research i found the header name should be 'Authorization' and the tokenName should be 'Bearer'. Ok lets try like this:

provideAuth({
        headerName: 'Authorization',
        headerPrefix: '',
        tokenName: 'Bearer',
        tokenGetter: () => {
            return JSON.parse(localStorage.getItem('bearerToken'));
        },
        globalHeaders: [{'Content-Type': 'application/json'}],
        noJwtError: true,
        noTokenScheme: true
    })

Still my ControllerMethod with the Authorize-Tag was not reached. Ok, one last try, maybe it works when i add 'Bearer ' manually:

        provideAuth({
        headerName: 'Authorization',
        headerPrefix: '',
        tokenName: 'Bearer',
        tokenGetter: () => {
            var token: string = JSON.parse(localStorage.getItem('bearerToken'));
            return 'Bearer ' + token;                
        },
        globalHeaders: [{'Content-Type': 'application/json'}],
        noJwtError: true,
        noTokenScheme: true
    })

and ... bombe surprise ... it worked ;) Playing around a little bit more i found out that tokenName can be empty or can contain anything else.
