### Other utility functions { #other-utility-functions }

Any other utility function that you call directly can be created with normal `def` or `async def` and FastAPI won't affect the way you call it.

Isso significa que no lugar do processo normal de seus usuários enviarem requisições para a sua API, é a **sua API** (ou sua aplicação) que poderia **enviar requisições para o sistema deles** (para a API deles, a aplicação deles).

Isso normalmente é chamado de **webhook**.

## What is "Form Data" { #what-is-form-data }

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

**FastAPI** will make sure to read that data from the right place instead of JSON.

/// note | Technical Details

Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded` when it doesn't include files.

### Diğer yardımcı fonksiyonlar

Doğrudan çağırdığınız diğer herhangi bir yardımcı fonksiyonu, normal "def" veya "async def" ile tanimlayabilirsiniz. FastAPI onu çağırma şeklinizi etkilemez.

    @Override
    public void setUp() throws Exception {
        super.setUp();
        indexUpdateCallback = new FileListIndexUpdateCallbackImpl(null, null, 1);
    }

    /** Case 1: Normal merge (no duplicates) */
    public void test_mergeResponseData_noOverwrite() {
        Map<String, Object> dataMap = new HashMap<>();
        dataMap.put("a", "A0");
        Map<String, Object> responseDataMap = new HashMap<>();

But if you go with your browser to <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000/app</a> you will see the normal response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

So, it won't expect to be accessed at `http://127.0.0.1:8000/api/v1/app`.

	in.macros[name] = &Macro{

}

// macroDefinition returns the list of formals and the tokens of the definition.
// The argument list is nil for no parens on the definition; otherwise a list of
// formal argument names.

* `TRACE`

In the HTTP protocol, you can communicate to each path using one (or more) of these "methods".

---

When building APIs, you normally use these specific HTTP methods to perform a specific action.

Normally you use:

* `POST`: to create data.
* `GET`: to read data.
* `PUT`: to update data.
* `DELETE`: to delete data.

      pattern.endsWith("..")
    ) {
      // Invalid pattern.
      return false
    }

    // Normalize hostname and pattern by turning them into absolute domain names if they are not
    // yet absolute. This is needed because server certificates do not normally contain absolute
    // names or patterns, but they should be treated as absolute. At the same time, any hostname

HTTP protokolünde, bu "metodlardan" birini (veya daha fazlasını) kullanarak her bir yol ile iletişim kurabilirsiniz.

---

API oluştururkan, belirli bir amaca hizmet eden belirli HTTP metodlarını kullanırsınız.

Normalde kullanılan:

* `POST`: veri oluşturmak.
* `GET`: veri okumak.
* `PUT`: veriyi güncellemek.
* `DELETE`: veriyi silmek.

Bu nedenle, OpenAPI'da HTTP metodlarından her birine "operasyon" denir.
