# HTML forms example

This example shows how to parse `application/x-www-form-urlencoded`-encoded
data using `libweb`s `form` API, using untrusted user input.

## How to build

If using `make(1)`, just run `make` from this directory.

If using CMake, examples are built by default when configuring the project
from [the top-level `CMakeLists.txt`](../../CMakeLists.txt).

## How to run

Run the executable with a `application/x-www-form-urlencoded`-encoded given
as its only argument.

For example:

```sh
$ ./form 'username=admin&password=mypassword'
```

Shall return:

```
key=username, value=admin, cnt=1
key=password, value=mypassword, cnt=2
```

An invalid string shall be reported to `stderr`:

```sh
$ ./form 'username=admin&thisisawrongvalue'
```

```
main: invalid user input: username=admin&thisisawrongvalue
```
