Adding an Authorization Bearer header via Zinc

I am building some pharo scripts to edit tasks in the Asana.com system.

I have generated a Personal Access Token, and the terminal command of:

curl -H "Authorization: Bearer 12345abc" https://app.asana.com/api/1.0/users/me

Returns 200/ok, and the right data.

However, the pharo commands

tmp1 := ZnClient new.

tmp1 headerAt: 'Authorization:' put: 'Bearer 12345abc'.

tmp1 url: 'https://app.asana.com/api/1.0/users/me'.

tmp1 get.

Results in an authorisation error.

I haven't tried using Zinc to access authenticated sites before, what am I doing wrong?

Cheers

Andy

Re: Adding an Authorization Bearer header via Zinc

Have a look at

ZnClient>>#username:password:
ZnClient>>#setBasicAuthenticationUsername:password:

ZnRequest>>#setBasicAuthenticationUsername:password:
ZnRequest>>#setAuthorization:

and their senders. This should get you started. It is possible/probable that you have to set the #url: before you modify the headers (you can check that by inspecting the ZnClient object).

You have a colon in the name of the header. I‘m not sure zinc removes it. It could be a problem.

Duh. Yes, there should be not colon at the end of the header name.

Ah, spot on. Apparently, we need the colon for Curl, but not for Pharo. Also, response setAuthorization turned out to be the best approach. For anyone searching this list, in the future, for Asana connectivity, my PoC is:

tmp1 := ZnClient new.

tmp1 request setAuthorization: 'Bearer <put your personal access token here>';

url: 'https://app.asana.com/api/1.0/users/me'.

tmpJSON := NeoJSONReader fromString: tmp1 get.
