You could use it while developing your app to log the body and debug it, return it to the user, etc.

```Python hl_lines="14"
{!../../docs_src/handling_errors/tutorial005.py!}
```

Now try sending an invalid item like:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

You will receive a response telling you that the data is invalid containing the received body:

    the request already contains an `Accept` header.

 *  Fix: Don't crash with a `NullPointerException` if a server sends a close while we're sending a
    ping. OkHttp had a race condition bug.


## Version 4.6.0

 *  Fix: Follow HTTP 307 and 308 redirects on methods other than GET and POST. We're reluctant to

     * `ID <= lastGoodStreamId` can only be replayed on a new connection if they are idempotent.

     * @param lastGoodStreamId the last stream ID the peer processed before sending this message. If

// by AWS S3.
//
// An AWS S3 ETag is 16 bytes long and, in case of a multipart
// upload, has a `-N` suffix encoding the number of object parts.
// An ETag is not AWS S3 compatible when encrypted. When sending
// an ETag back to an S3 client it has to be formatted to be
// AWS S3 compatible.
//
// Therefore, Format returns the last 16 bytes of an encrypted
// ETag.

Ao invés disso, sendo um sistema "assíncrono", uma vez finalizada, a tarefa pode esperar um pouco (alguns microssegundos) para que o computador / programa finalize o que quer que esteja fazendo,e então volte para pegar o resultado e continue trabalhando com ele.

E, então, adicionando o argumento de palavra-chave extra `hashed_password=hashed_password`, como em:

```Python
UserInDB(**user_in.dict(), hashed_password=hashed_password)
```

...acaba sendo como:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

2. By using a `with` block, we make sure that the file-like object is closed after the generator function is done. So, after it finishes sending the response.
3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function (`iterfile`).
