UriParamsIter

Added in version 2.66.

class UriParamsIter(*args, **kwargs)

Constructors:

UriParamsIter()

Methods

class UriParamsIter

init(params: str, length: int, separators: str, flags: UriParamsFlags) → None

Initializes an attribute/value pair iterator.

The iterator keeps pointers to the params and separators arguments, those variables must thus outlive the iterator and not be modified during the iteration.

If WWW_FORM is passed in flags, + characters in the param string will be replaced with spaces in the output. For example, foo=bar+baz will give attribute foo with value bar baz. This is commonly used on the web (the https and http schemes only), but is deprecated in favour of the equivalent of encoding spaces as `%20`.

Unlike with parse_params(), CASE_INSENSITIVE has no effect if passed to flags for init(). The caller is responsible for doing their own case-insensitive comparisons.

GUriParamsIter iter;
GError *error = NULL;
gchar *unowned_attr, *unowned_value;

g_uri_params_iter_init (&iter, "foo=bar&baz=bar&Foo=frob&baz=bar2", -1, "&", G_URI_PARAMS_NONE);
while (g_uri_params_iter_next (&iter, &unowned_attr, &unowned_value, &error))
  {
    g_autofree gchar *attr = g_steal_pointer (&unowned_attr);
    g_autofree gchar *value = g_steal_pointer (&unowned_value);
    // do something with attr and value; this code will be called 4 times
    // for the params string in this example: once with attr=foo and value=bar,
    // then with baz/bar, then Foo/frob, then baz/bar2.
  }
if (error)
  // handle parsing error

Parameters:

• params – a %-encoded string containing attribute=value parameters

• length – the length of params, or -1 if it is nul-terminated

• separators – the separator byte character set between parameters. (usually &, but sometimes ; or both &;). Note that this function works on bytes not characters, so it can’t be used to delimit UTF-8 strings for anything but ASCII characters. You may pass an empty set, in which case no splitting will occur.

• flags – flags to modify the way the parameters are handled.

next() → tuple[bool, str, str]

Advances iter and retrieves the next attribute/value. False is returned if an error has occurred (in which case error is set), or if the end of the iteration is reached (in which case attribute and value are set to None and the iterator becomes invalid). If True is returned, next() may be called again to receive another attribute/value pair.

Note that the same attribute may be returned multiple times, since URIs allow repeated attributes.
