# Request Parameters

Here's the reference information for the request parameters.

These are the special functions that you can put in *path operation function* parameters or dependency functions with `Annotated` to get data from the request.

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python

MockWebServer for JUnit 4
=========================

This module integrates mockwebserver3.MockWebServer with JUnit 4.

To use, first add this library as a test dependency:

```
testImplementation("com.squareup.okhttp3:mockwebserver3-junit4:5.1.0")
```

Then in tests annotated `@org.junit.Test`, you may declare a field with the `@Rule` annotation:

```
@Rule public final MockWebServerRule serverRule = new MockWebServerRule();
```

    constant is included for completeness.
 *  New: Upgrade to Okio 1.14.0.

     ```xml
     <dependency>
       <groupId>com.squareup.okio</groupId>
       <artifactId>okio</artifactId>
       <version>1.14.0</version>
     </dependency>

     com.squareup.okio:okio:1.14.0
     ```

 *  Fix: Handle `HTTP/1.1 100 Continue` status lines, even on requests that did

 * or implied. See the License for the specific language governing permissions and limitations under
 * the License.

    model: CIBuildModel,
    prevStage: Stage,
    os: Os? = null,
) {
    if (os == null || stageWithOsTriggers.getOrDefault(prevStage.stageName, emptyList()).contains(os)) {
        dependency(RelativeId(stageTriggerId(model, prevStage, os))) {
            snapshot {
                onDependencyFailure = FailureAction.FAIL_TO_START
                onDependencyCancel = FailureAction.FAIL_TO_START
            }

            // Validate required argument and interact with the provided CIFSContext
            if (tc == null) {
                throw new NullPointerException("tc");
            }
            // Exercise interaction with dependency for verification purposes
            // These methods do not throw and allow interaction checks.
            tc.getConfig();
            tc.getCredentials();

# Background Tasks - `BackgroundTasks`

You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```

        b.addDependency("a", "1.0");
        assertThrows(
                CyclicDependencyException.class,
                () -> collect(a),
                "Should have failed on cyclic dependency not involving project");
    }

    @Test
    @Disabled("works, but we don't fail on cycles presently")
    void testCircularDependencyIncludingCurrentProject()

yapılabileceklere nispeten benzeyen bir şey elde ediyor.

Angular 2'den ilham alan, içine gömülü bir <abbr title="Bağımlılık enjeksiyonu: Dependency Injection">bağımlılık enjeksiyonu</abbr> sistemi var. Bildiğim diğer tüm bağımlılık enjeksiyonu sistemlerinde olduğu gibi"<abbr title="Injectable: dependency injection sistemi tarafından enjekte edilecek dependency (bağımlılık)">bağımlılık</abbr>"ları önceden kaydetmenizi gerektiriyor. Böylece projeyi daha detaylı hale getiriyor ve kod tekrarını da arttırıyor....

 *  New: Change `HeldCertificate.Builder` to use its own ASN.1 certificate encoder. This is part
    of our effort to remove the okhttp-tls module's dependency on Bouncy Castle. We think Bouncy
    Castle is great! But it's a large dependency (6.5 MiB) and its security provider feature
    impacts VM-wide behavior.

 *  New: Reduce contention for applications that make a very high number of concurrent requests.
