[Emacs][Elisp]HTTP Post の elisp を interactive 対応

POST 先のサーバ、渡すパラメータ (First name, Last name) を入力することができるようになる

(defun http-post (server fname lname)
  (interactive "sServer:\nsFirst name:\nsLast name:")
  (setq proc (open-network-stream "http-proc" "*http-buffer*" server 80))
  (set-process-coding-system proc 'binary 'binary)
  (setq content-len
    (+ (+ (+ (length "fname=") (length fname)) (length "&lname=")) (length lname)))
  (process-send-string
    proc
    (format (concat
    "POST /test.php HTTP/1.0\r\n"
    "Content-Type: application/x-www-form-urlencoded\r\n"
    "Content-Length: "
    (number-to-string content-len)
    "\r\n"
    "\r\n"
    "fname="
    fname
    "&lname="
    lname))))
