cowboy_req:parse_qs(3)

+ +

Name

+

cowboy_req:parse_qs - Parse the query string

+

Description

+
+
parse_qs(Req :: cowboy_req:req())
+    -> [{Key :: binary(), Value :: binary() | true}]
+
+

Parse the query string as a list of key/value pairs.

+

Arguments

+
Req
+

The Req object.

+
+
+

Return value

+

The parsed query string is returned as a list of key/value pairs. The key is a binary string. The value is either a binary string, or the atom true. Both key and value are case sensitive.

+

The atom true is returned when a key is present in the query string without a value. For example, in the following URIs the key <<"edit">> will always have the value true:

+
  • /posts/42?edit +
    • +
  • /posts/42?edit&exclusive=1 +
    • +
  • /posts/42?exclusive=1&edit +
    • +
  • /posts/42?exclusive=1&edit&from=web +
    • +
+

Changelog

+
  • 2.0: The parsed value is not longer cached in the Req object. +
    • +
  • 2.0: Only the parsed query string is returned, it is no longer wrapped in a tuple. +
    • +
  • 2.0: Function introduced. Replaces qs_val/1 and qs_vals/1. +
    • +
+

Examples

+
Parse the query string and convert the keys to atoms
+
+
ParsedQs = cowboy_req:parse_qs(Req),
+AtomsQs = [{binary_to_existing_atom(K, latin1), V}
+    || {K, V} <- ParsedQs].
