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.



Installation

============



Grab the nginx source code from [nginx.org](http://nginx.org/), for example,

the version 1.9.15 (see [nginx compatibility](#compatibility)), and then build the source with this module:



```bash

wget 'http://nginx.org/download/nginx-1.9.15.tar.gz'

tar -xzvf nginx-1.9.15.tar.gz

cd nginx-1.9.15/



./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 [form-input-nginx-module file list](http://github.com/calio/form-input-nginx-module/tags), and the latest tarball for [ngx_devel_kit](https://github.com/simpl/ngx_devel_kit) from its [file list](https://github.com/simpl/ngx_devel_kit/tags).



Building as a dynamic module

----------------------------



Starting from NGINX 1.9.11, you can also compile this module as a dynamic module, by using the `--add-dynamic-module=PATH` option instead of `--add-module=PATH` on the

`./configure` command line above. And then you can explicitly load the module in your `nginx.conf` via the [load_module](http://nginx.org/en/docs/ngx_core_module.html#load_module)

directive, for example,



```nginx

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;

```

Usage

=====



```nginx

set_form_input $variable;

set_form_input $variable argument;



set_form_input_multi $variable;

set_form_input_multi $variable argument;

```



example:



```nginx

#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

}

```

Limitations

===========



* 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.
