# Using the Request Directly { #using-the-request-directly }

Up to now, you have been declaring the parts of the request that you need with their types.

Taking data from:

* The path as parameters.
* Headers.
* Cookies.
* etc.

And by doing so, **FastAPI** is validating that data, converting it and generating documentation for your API automatically.

But there are situations where you might need to access the `Request` object directly.

            "input": "plumbus"
        }
    ]
}
```

## 總結

你可以使用 **Pydantic 模型**在 **FastAPI** 中聲明**查詢參數**。😎

/// tip

劇透警告：你也可以使用 Pydantic 模型來聲明 cookie 和 headers，但你將在本教學的後面部分閱讀到這部分內容。🤫

## 什么是容器

容器（主要是 Linux 容器）是一种非常**轻量级**的打包应用程序的方式，其包括所有依赖项和必要的文件，同时它们可以和同一系统中的其他容器（或者其他应用程序/组件）相互隔离。

		requestXML []byte // override request XML
		wantResult string
		wantErr    bool
	}{
		{
			name:  "select-all",
			input: testInput,
			query: ``,
			// Since we are doing offset, no headers are used.
			wantResult: `{"_1":"2","_2":"2017-01-02T03:04Z","_3":"-5","_4":" 0.765111","_5":""}`,
			requestXML: []byte(`<?xml version="1.0" encoding="UTF-8"?>
<SelectObjectContentRequest>

* `response`를 반환하기 전에 추가로 `response`를 수정할 수 있습니다.
