Hi everybody,
I'm trying to POST some JSON data to a web service:
(ql:quickload :st-json) (ql:quickload :cl-json) (ql:quickload :drakma)
(defvar *rc* (merge-pathnames (user-homedir-pathname) ".apirc"))
(defvar *user* (with-open-file (s *rc*) (st-json:read-json s)))
(defvar api-url (st-json:getjso "url" *user*)) (defvar api-key (st-json:getjso "key" *user*)) (defvar api-email (st-json:getjso "email" *user*))
(setf drakma:*header-stream* *standard-output*)
(defvar *req* '(("dataset" . "tigge") ("step" . "24") ("date" . "20071001") ("time" . "00") ("origin" . "all")))
(format t "json:~S~%" (json:encode-json-to-string *req*))
(defun retrieve (api request) (let* ((cookie-jar (make-instance 'drakma:cookie-jar)) (extra-headers (list (cons "From" api-email) (cons "X-API-KEY" api-key))) (url (concatenate 'string api-url api "/requests")) (stream (drakma:http-request url :additional-headers extra-headers :accept "application/json" :method :post :content-type "application/json" :external-format-out :utf-8 :external-format-in :utf-8 :redirect 100 :cookie-jar cookie-jar :content (json:encode-json-to-string request) :want-stream t))) (st-json:read-json stream)))
(retrieve "/datasets/tigge" *req*)
Unfortunately, I get an error, although the data seems to be encoded OK to JSON and the headers generated by drakma too, I think. Apparently something is wrong with the :content (the list of integers in the errors message is just the list of ASCII codes of the JSON encoded data).

Any idea what's wrong with this code? Many thanks in advance.
