# 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.

/**
 * Service class for managing search logs and related analytics.
 *
 * This service provides functionality for querying, aggregating, and managing
 * various types of search logs including search logs, click logs, favorite logs,
 * and user information logs. It supports different aggregation types for
 * analytics and reporting purposes.
 */
public class SearchLogService {

    /** Date format pattern for parsing time ranges. */

            op.setRefreshPolicy(Constants.TRUE);
        });

        ComponentUtil.getPathMappingHelper().init();
    }

    /**
     * Gets the path mapping list by process types.
     *
     * @param processTypeList the process type list
     * @return the path mapping list
     */
    public List<PathMapping> getPathMappingList(final Collection<String> processTypeList) {

    val builderList: List<KeyStore.Builder> =
      listOf(
        KeyStore.Builder.newInstance("PKCS11", null, KeyStore.CallbackHandlerProtection(callbackHandler)),
        // Example if you want to combine multiple keystore types
        // KeyStore.Builder.newInstance("PKCS12", null, File("keystore.p12"), PasswordProtection("rosebud".toCharArray()))
      )

    val keyManagerFactory = KeyManagerFactory.getInstance("NewSunX509")

### 更主流的 Python

全部都基于标准的 **Python 3.6 类型**声明（感谢 Pydantic ）。没有新的语法需要学习。只需要标准的 Python 。

如果你需要2分钟来学习如何使用 Python 类型（即使你不使用 FastAPI ），看看这个简短的教程：[Python Types](python-types.md){.internal-link target=_blank}。

编写带有类型标注的标准 Python：

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str

     * addValue()} methods, is not significant.
     *
     * <p><b>Note:</b> in general, code should assume that the string form returned by {@code
     * ToStringHelper} for a given object may change. In particular, the list of types which are
     * checked for emptiness is subject to change. We currently check {@code CharSequence}s, {@code
     * Collection}s, {@code Map}s, optionals (including Guava's), and arrays.
     *
     * @since 33.4.0
