# 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.

* **OAuth2** (also with **JWT tokens**). Check the tutorial on [OAuth2 with JWT](tutorial/security/oauth2-jwt.md).
* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).

All built as reusable tools and components that are easy to integrate with your systems, data stores, relational and NoSQL databases, etc.

    implementation. This is useful in sandboxed environments like Google App
    Engine.

 *  **OkHttp now does cookies.** We've replaced `java.net.CookieHandler` with
    a new interface, `CookieJar` and added our own `Cookie` model class. This
    new cookie follows the latest RFC and supports the same cookie attributes
    as modern web browsers.

 *  **Form and Multipart bodies are now modeled.** We've replaced the opaque

        // cookie
        if (cookieSpec != null) {
            requestConfigBuilder.setCookieSpec(cookieSpec);
        }

        // cookie store
        httpClientBuilder.setDefaultCookieStore(cookieStore);
        if (cookieStore != null) {
            final Cookie[] cookies = getInitParameter(COOKIES_PROPERTY, new Cookie[0], Cookie[].class);
            for (final Cookie cookie : cookies) {

    builder.setHeader("cookie", "r=robot")
    assertThat(headersToList(builder)).containsExactly("Cookies: delicious", "cookie: r=robot")
  }

        .Builder()
        .clearHeaders()
        .addHeader("Cookie: s=square")
        .addHeader("Cookies: delicious")
