Vamos começar de onde paramos no capítulo anterior e incrementá-lo.

## Sobre o JWT { #about-jwt }

JWT significa "JSON Web Tokens".

É um padrão para codificar um objeto JSON em uma string longa e densa sem espaços. Ele se parece com isso:

```

```

                        "title": "Model",
                        "required": ["name"],
                        "type": "object",
                        "properties": {"name": {"title": "Name", "type": "string"}},
                    }
                }
            },
        }

        memberRenderers.add(new BlocksRenderer(linkRenderer, listener));
    }

    public void mergeContent(ClassDoc classDoc, Element parent) {
        listener.start(String.format("class %s", classDoc.getName()));
        try {
            Element chapter = parent.getOwnerDocument().createElement("chapter");
            parent.appendChild(chapter);

Exemplos de literais de string em trechos de código: `"this"`, `'that'`.

Um exemplo difícil de literais de string em trechos de código: `f"I like {'oranges' if orange else "apples"}"`

		uint16PtrValue   = &uint16Value
		uint32PtrValue   = &uint32Value
		uint64PtrValue   = &uint64Value
		maxInt64Plus1Ptr = &maxInt64Plus1
	)
	tests := []struct {
		name    string
		value   interface{}
		want    interface{}
		wantErr bool
	}{
		{
			name:    "int",
			value:   intValue,
			want:    time.Unix(int64(intValue), 0).UTC(),
			wantErr: false,
		},
		{

    server.start()

    val call1 =
      client.newCall(
        Request
          .Builder()
          .url(server.url("/"))
          .build(),
      )
    call1.execute().use { response -> response.body.string() }

    listener.shouldClose = true
    // Large headers are a likely reason the servers would cut off the connection before it completes sending
    // request headers.
    // 431 "Request Header Fields Too Large"

JSON sadece UTF-8 ile encode edilmiş string'ler içerebilir, dolayısıyla ham bytes içeremez.

Base64 ikili veriyi string olarak encode edebilir, ancak bunu yapmak için orijinal ikili veriden daha fazla karakter kullanır; bu yüzden genellikle normal dosyalardan daha verimsiz olur.
