=encoding utf-8
=head1 Name
form-input-nginx-module - NGINX module that reads HTTP POST and PUT request body encoded in "application/x-www-form-urlencoded" and parses the arguments into nginx variables.
=head1 Description
This is a nginx module that reads HTTP POST and PUT request body encoded
in "application/x-www-form-urlencoded", and parse the arguments in
request body into nginx variables.
This module depends on the ngx_devel_kit (NDK) module.
=head1 Installation
Grab the nginx source code from L<nginx.org|http://nginx.org/>, for example,
the version 1.9.7 (see L<nginx compatibility>), and then build the source with this module:
wget 'http://nginx.org/download/nginx-1.9.7.tar.gz'
tar -xzvf nginx-1.9.7.tar.gz
cd nginx-1.9.7/
./configure --add-module=/path/to/ngx_devel_kit \
--add-module=/path/to/form-input-nginx-module
make -j2
make install
Download the latest version of the release tarball of this module from L<form-input-nginx-module file list|http://github.com/calio/form-input-nginx-module/tags>, and the latest tarball for L<ngx_devel_kit|https://github.com/simpl/ngx_devel_kit> from its L<file list|https://github.com/simpl/ngx_devel_kit/tags>.
=head2 Building as a dynamic module
Starting from NGINX 1.9.11, you can also compile this module as a dynamic module, by using the C<--add-dynamic-module=PATH> option instead of C<--add-module=PATH> on the
C<./configure> command line above. And then you can explicitly load the module in your C<nginx.conf> via the L<load_module|http://nginx.org/en/docs/ngx_core_module.html#load_module>
directive, for example,
load_module /path/to/modules/ndk_http_module.so; # assuming NDK is built as a dynamic module too
load_module /path/to/modules/ngx_http_form_input_module.so;
=head1 Usage
set_form_input $variable;
set_form_input $variable argument;
set_form_input_multi $variable;
set_form_input_multi $variable argument;
example:
#nginx.conf
location /foo {
# ensure client_max_body_size == client_body_buffer_size
client_max_body_size 100k;
client_body_buffer_size 100k;
set_form_input $data; # read "data" field into $data
set_form_input $foo foo; # read "foo" field into $foo
}
location /bar {
# ensure client_max_body_size == client_body_buffer_size
client_max_body_size 1m;
client_body_buffer_size 1m;
set_form_input_multi $data; # read all "data" field into $data
set_form_input_multi $foo data; # read all "data" field into $foo
array_join ' ' $data; # now $data is an string
array_join ' ' $foo; # now $foo is an string
}
=head1 Limitations
=over
=item *
ngx_form_input will discard request bodies that are buffered
to disk files. When the client_max_body_size setting is larger than
client_body_buffer_size, request bodies that are larger
than client_body_buffer_size (but no larger than
client_max_body_size) will be buffered to disk files.
So it's important to ensure these two config settings take
the same values to avoid confustion.
