For example, if you need to store it in a database.

For that, **FastAPI** provides a `jsonable_encoder()` function.

## Using the `jsonable_encoder`

Let's imagine that you have a database `fake_db` that only receives JSON compatible data.

For example, it doesn't receive `datetime` objects, as those are not compatible with JSON.

* And many other things...

All these, while minimizing code repetition.

## First Steps

Let's see a very simple example. It will be so simple that it is not very useful, for now.

But this way we can focus on how the **Dependency Injection** system works.

### Create a dependency, or "dependable"

Let's first focus on the dependency.

                .joinToString(",") { "%dep.${it.id}.env.BUILD_ID%" }

            val dependencyBaselines = performanceTestProject.performanceTests.first { it.testProjects.isNotEmpty() }.let { "%dep.${it.id}.performance.baselines%" }

            gradleRunnerStep(
                model,
                ":$performanceProjectName:$taskName --channel %performance.channel%",
                extraParameters = listOf(

    SignerType: 1
  }
}
```

### Using MinIO Console

- Open MinIO URL on the browser, lets say <http://localhost:9000/>
- Click on `Login with SSO`
- User will be redirected to the Casdoor user login page, upon successful login the user will be redirected to MinIO page and logged in automatically,

 *
 * ```java
 * HttpUrl url = HttpUrl.parse("http://who-let-the-dogs.out").newBuilder()
 *     .addPathSegment("_Who?_")
 *     .query("_Who?_")
 *     .fragment("_Who?_")
 *     .build();
 * System.out.println(url);
 * ```
 *
 * This prints:
 *
 * ```
 * http://who-let-the-dogs.out/_Who%3F_?_Who?_#_Who?_
 * ```
 *

# Query Parameters and String Validations

**FastAPI** allows you to declare additional information and validation for your parameters.

Let's take this application as example:

=== "Python 3.10+"

    ```Python hl_lines="7"
    {!> ../../../docs_src/query_params_str_validations/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="9"
    {!> ../../../docs_src/query_params_str_validations/tutorial001.py!}
    ```

    bytesIn.writeByte(0x18)
    hpackReader!!.readHeaders()
    assertThat(hpackReader!!.headerCount).isEqualTo(1)
  }

  /** Header table backing array is initially 8 long, let's ensure it grows.  */
  @Test
  fun dynamicallyGrowsBeyond64Entries() {
    // Lots of headers need more room!
    hpackReader = Hpack.Reader(bytesIn, 16384, 4096)

        firCallSiteSession = firFakeFile.llFirSession
        firOriginalFile = originalFile.getOrBuildFirFile(firResolveSession)
        firExplicitReceiver = explicitReceiver?.let(::findReceiverFirExpression)
    }

    override fun computeApplicability(candidate: KtCallableSymbol): KtExtensionApplicabilityResult {
        require(candidate is KtFirSymbol<*>)
