How do I set withCredentials header?

[rgkirch]

I can't figure out how to set headers. I'm making a cors request and I need "withCredentials" to be false. This gives me a cors error.

(def m (martian-http/bootstrap "http://icanhazip.com"
                               [{:route-name :ip
                                 :path-parts []
                                 :method :get}]
                               {:interceptors (concat [{:name ::cors
                                                        :enter #(update-in % [:request :headers] merge {"withCredentials" "false"})}]
                                                      martian-http/default-interceptors)}))
(martian/request-for m :ip)
;; {:headers {"withCredentials" "false"}, :method :get, :url "http://icanhazip.com", :as :auto}

(go (println (<! (martian/response-for m :ip))))

cors error

Access to XMLHttpRequest at 'http://icanhazip.com/' from origin 'http://localhost:8081' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

This doesn't give me a cors error.

(require '[cljs-http.client :as client])
(go (println (<! (client/get "http://icanhazip.com" {:with-credentials? false}))))

Thanks!

Hi,

You can let the http library do it for you, to make the request identical to your working example:

{:name ::cors
 :enter #(assoc-in % [:request :with-credentials?] false)}

The request map is passed directly to the http library, so it should work. Not sure if it does anything other than set the header like you were trying, but I'm guessing it does.

(You were doing the right thing to set headers, as you saw from the request-for result, but I think just setting the header is not enough)

Thank you! Yea, associng :with-credentials? worked.
