Hi,

When I post json objects from jquery

$.ajax({
        type: 'POST',
        url: '/url',
        dataType: 'json',
        data:  {"key":"val","hash",{"foo":"bar"}}

then the "hash" parameter is posted like this: "hash[foo]=bar"

If I then in hunchentoot have

(define-easy-handler (fn :uri "/url")
    ((hash :parameter-type 'hash-table))
.....

The hash is expected to be posted like this: "hash{foo}=bar"?
So I wonder if it would be correct to enable the "hash[foo]=bar" syntax for hash tables.

Maybe it should be an argument that specifies if compute-hash-table-parameter should use [] or {}.
This little experiment worked for me, here I just added \\[ and \\] to the regexp.

Should I bother to make a patch?

(defun compute-hash-table-parameter (parameter-name type parameters key-type test-function)
  "Retrieves all parameters from PARAMETERS which are named like                                                                                
\"PARAMETER-NAME{FOO}\" or \"PARAMETER-NAME[FOO]\"  \(where FOO is any sequence of characters                                                                               
not containing curly brackets), converts them to TYPE, and                                                                                      
returns a hash table with test function TEST-FUNCTION where the                                                                                 
corresponding value is associated with the key FOO \(converted to                                                                               
KEY-TYPE)."
  (let ((hash-table (make-hash-table :test test-function)))
    (loop for (full-name . value) in parameters
          for key = (register-groups-bind (name key-string)
                        ("^(.*)[{\\[]([^\\[\\]{}]+)[}\\]]$" full-name)
                      (when (string= name parameter-name)
                        (convert-parameter key-string key-type)))
          when key
          do (setf (gethash key hash-table)
                   (convert-parameter value type)))
    hash-table))
