} else {
        requestBuilder.header("Transfer-Encoding", "chunked")
        requestBuilder.removeHeader("Content-Length")
      }
    }

    if (userRequest.header("Host") == null) {
      requestBuilder.header("Host", userRequest.url.toHostHeader())
    }

    if (userRequest.header("Connection") == null) {
      requestBuilder.header("Connection", "Keep-Alive")
    }

因此，這段：

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

會被執行。

如果你是匯入該模組（檔案），就不會發生這件事。

所以，如果你有另一個檔案 `importer.py`，內容如下：

```Python
from myapp import app

# 其他程式碼
```

在那種情況下，`myapp.py` 中自動建立的變數 `__name__` 就不會是 `"__main__"`。

因此，這一行：

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

就不會被執行。

/// info | 說明

	Bucket          Bucket `json:"bucket"`
	Object          Object `json:"object"`
}

// Source represents client information who triggered the event.
type Source struct {
	Host      string `json:"host"`
	Port      string `json:"port"`
	UserAgent string `json:"userAgent"`
}

// Event represents event notification information defined in

        add(buildCryptoSx(client)) // 521 - server down
      }
      add(buildChantra(client))
    }

  private fun getByIp(host: String): InetAddress =
    try {
      InetAddress.getByName(host)
    } catch (e: UnknownHostException) {
      // unlikely
      throw RuntimeException(e)
    }

$ python myapp.py
```

</div>

então a variável interna `__name__` no seu arquivo, criada automaticamente pelo Python, terá como valor a string `"__main__"`.

Então, a seção:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

vai executar.

Isso não acontecerá se você importar esse módulo (arquivo).

Então, se você tiver outro arquivo `importer.py` com:

```Python
