# Request Body { #request-body }

When you need to send data from a client (let's say, a browser) to your API, you send it as a **request body**.

A **request** body is data sent by the client to your API. A **response** body is the data your API sends to the client.

 * Provides common functionality for handling initialization parameters,
 * content length checks, and default method implementations.
 * It defines the basic structure and configuration options for crawler clients.

/// tip | Tipp

Bedenken Sie, dass JSON nur `str` als Schlüssel unterstützt.

Aber Pydantic hat automatische Datenkonvertierung.

Das bedeutet, dass Ihre API-Clients nur Strings senden können, aber solange diese Strings nur Zahlen enthalten, wird Pydantic sie konvertieren und validieren.

Und das `dict`, welches Sie als `weights` erhalten, wird `int`-Schlüssel und `float`-Werte haben.

	biggerBufMax = maxBufferSize

	// If there is a queue, merge up to this many messages.
	maxMergeMessages = 50

	// clientPingInterval will ping the remote handler every 15 seconds.
	// Clients disconnect when we exceed 2 intervals.
	clientPingInterval = 15 * time.Second

	// Deadline for single (non-streaming) requests to complete.
	// Used if no deadline is provided on context.

    // Sleep longer than the HTTP client's read timeout.
    Thread.sleep((client.readTimeoutMillis + 500).toLong())
    server.send("abc")
    clientListener.assertTextMessage("abc")

# Arquivos de Requisição { #request-files }

Você pode definir arquivos para serem enviados pelo cliente usando `File`.

/// info | Informação

Para receber arquivos enviados, primeiro instale o <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Garanta que você criou um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, o ativou e então o instalou, por exemplo:

	// credElement is fetched first to skip replacing the space in access key.
	credElement := strings.TrimPrefix(strings.Split(strings.TrimSpace(v4Auth), ",")[0], signV4Algorithm)
	// Replace all spaced strings, some clients can send spaced
	// parameters and some won't. So we pro-actively remove any spaces
	// to make parsing easier.
	v4Auth = strings.ReplaceAll(v4Auth, " ", "")
	if v4Auth == "" {
		return sv, ErrAuthHeaderEmpty
	}
