# mod-fixparams

Fix invalid parameters to urlencoded valid parameters.

## Install

First, you have to enable mod_lua. For example, the following:

```sh
sudo a2enmod lua
```

Second, you have to copy fixparams.lua to /etc/apache2/.

```sh
sudo cp fixparams.lua /etc/apache2/
```

Finally, configure as follows:

```apache
LuaInputFilter fix_body_params_filter /etc/apache2/fixparams.lua fix_body_params_filter
  
<Location />
    LuaHookTranslateName /etc/apache2/fixparams.lua fix_url_params
    SetInputFilter fix_body_params_filter
</Location>
```

## Characters to be encoded

|Behavior |Characters                 |
|---------|---------------------------|
|No encode|0-9 a-z A-Z % & + - . = _ ~|
|Encode   |others                     |

If you change this behavior, you can achive by modifying a noencode variable in fixparams.lua.

## Example

Suppose publish this page.

```php:test.php
QueryString: <?php echo $_SERVER['QUERY_STRING'] ?>

Body: <?php echo file_get_contents('php://input') ?>

```

Let's test the module using curl.

```sh
curl 'http://localhost/test.php?a1=x1@あ+&a2=y2*い~' -d 'b1=x1@あ+&b2=y2*い~' -v
