Let's say you have a file structure as described in [Bigger Applications](bigger-applications.md):

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

In the file `main.py` you have your **FastAPI** app:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

### Testing file { #testing-file }

        <configuration>
          <version>2.0.0</version>
          <velocityBasedir>${project.basedir}/../../src/mdo</velocityBasedir>
          <models>
            <model>src/main/mdo/settings.mdo</model>
          </models>
          <templates>
            <template>model.vm</template>
          </templates>
          <params>
            <param>packageModelV4=org.apache.maven.api.settings</param>

Try to find the good side. In general, if people are not being unfriendly, try to thank their effort and interest, even if you disagree with the main subject (discussion, PR), just thank them for being interested in the project, or for having dedicated some time to try to do something.

It's difficult to convey emotion in text, use emojis to help. 😅

你可以在編輯器中連接偵錯器，例如 Visual Studio Code 或 PyCharm。

## 呼叫 `uvicorn` { #call-uvicorn }

在你的 FastAPI 應用程式中，直接匯入並執行 `uvicorn`：

{* ../../docs_src/debugging/tutorial001_py310.py hl[1,15] *}

### 關於 `__name__ == "__main__"` { #about-name-main }

`__name__ == "__main__"` 的主要目的是，當你的檔案以以下方式呼叫時，執行某些程式碼：

<div class="termy">

```console
$ python myapp.py
```

</div>

但當其他檔案匯入它時不會執行，例如：

```Python
from myapp import app
```

            if (isBeforeOrAfterPhase(task)) {
                String prevTask = task;
                task = PhaseId.of(task).phase();
                LOGGER.warn("Illegal call to phase '{}'. The main phase '{}' will be used instead.", prevTask, task);
            }
            if (isGoalSpecification(task)) {
                // "pluginPrefix[:version]:goal" or "groupId:artifactId[:version]:goal"

					</div>
				</div>
			</div>
		</div>
	</main>
	<jsp:include page="../footer.jsp" />
	<input type="hidden" id="contextPath" value="${contextPath}" />
	<script type="text/javascript" src="${fe:url('/js/jquery-3.7.1.min.js')}"></script>
	<script type="text/javascript" src="${fe:url('/js/popper.min.js')}"></script>
	<script type="text/javascript" src="${fe:url('/js/bootstrap.min.js')}"></script>

```python
from main import app
```

Si votre code est structuré comme :

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

Alors vous définiriez le `entrypoint` comme :

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

ce qui équivaudrait à :

```python
from backend.main import app
```

import org.apache.maven.api.annotations.Nullable;

/**
 * {@code ArtifactCoordinates} completed with information about how the artifact will be used.
 * This information includes the dependency type (main classes, test classes, <i>etc.</i>),
 * a scope (compile, runtime <i>etc.</i>), an obligation (whether the dependency
 * is optional or mandatory), and possible exclusions for transitive dependencies.

    # Set job outputs to values from filter step
    outputs:
      docs: ${{ steps.filter.outputs.docs }}
    steps:
    - uses: actions/checkout@v6
    # For pull requests it's not necessary to checkout the code but for the main branch it is
    - uses: dorny/paths-filter@v4
      id: filter
      with:
        filters: |
          docs:
            - README.md
            - docs/**
            - docs_src/**

```python
from main import app
```

Kodunuz şöyle yapılandırılmışsa:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

O zaman `entrypoint`'i şöyle ayarlardınız:

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

Bu da şuna eşdeğer olur:

```python
from backend.main import app
```
