# `Request` class

You can declare a parameter in a *path operation function* or dependency to be of type `Request` and then you can access the raw request object directly, without any validation, etc.

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

/// tip

   * - 2 requests happen concurrently to a host that can be coalesced onto a single connection.
   * - Both request discover no existing connection. They both make a connection.
   * - The first request "wins the race".
   * - The second request discovers it "lost the race" and closes the connection it just opened.
   * - The second request uses the coalesced connection from request1.

/// note | Технические детали

У `Request` есть атрибут `request.scope` — это просто Python-`dict`, содержащий метаданные, связанные с HTTP-запросом.

У `Request` также есть `request.receive` — функция для «получения» тела запроса.

И `dict` `scope`, и функция `receive` являются частью спецификации ASGI.

Именно этих двух компонентов — `scope` и `receive` — достаточно, чтобы создать новый экземпляр `Request`.

    assertThat(result).contains(address("2a03:2880:f029:11:face:b00c:0:2"))
    val request1 = server.takeRequest()
    assertThat(request1.method).isEqualTo("GET")
    val request2 = server.takeRequest()
    assertThat(request2.method).isEqualTo("GET")
    assertThat(listOf(request1.url.encodedQuery, request2.url.encodedQuery))
      .containsExactlyInAnyOrder(
        "ct&dns=AAABAAABAAAAAAAABmdvb2dsZQNjb20AAAEAAQ",

        .cache(cache)
        .build()
    val request1 = Request(server.url("/"))
    client.newCall(request1).enqueue(callback)
    callback.await(request1.url).assertCode(200).assertBody("A")
    assertThat(server.takeRequest().headers["If-None-Match"]).isNull()
    val request2 = Request(server.url("/"))
    client.newCall(request2).enqueue(callback)
    callback.await(request2.url).assertCode(200).assertBody("A")

        .newClientBuilder()
        .proxy(socksProxy.proxy())
        .build()
    val request1 = Request.Builder().url(server.url("/")).build()
    val response1 = client.newCall(request1).execute()
    assertThat(response1.body.string()).isEqualTo("abc")
    val request2 = Request.Builder().url(server.url("/")).build()
    val response2 = client.newCall(request2).execute()
    assertThat(response2.body.string()).isEqualTo("def")
