/// tip | Совет

Чтобы это работало, вам нужно `pip install python-dotenv`.

///

### Файл `.env` { #the-env-file }

У вас может быть файл `.env` со следующим содержимым:

```bash
ADMIN_EMAIL="******@****.***"

/// tip | Tipp

Damit das funktioniert, müssen Sie `pip install python-dotenv` ausführen.

///

### Die `.env`-Datei { #the-env-file }

Sie könnten eine `.env`-Datei haben, mit:

```bash

				}
				return
			}
		}
	}()
	return func(err error) {
		if doneCh == nil {
			return
		}

		// Indicate we are ready to write.
		doneCh <- err

		// Wait for channel to be closed so we don't race on writes.
		<-doneCh

		// Clear so we can be called multiple times without crashing.
		doneCh = nil
	}, &closeNotifier{rc: r.Body, done: bodyDoneCh}
}

/// tip

For this to work, you need to `pip install python-dotenv`.

///

### The `.env` file { #the-env-file }

You could have a `.env` file with:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

/// tip | Dica

Para isso funcionar, você precisa executar `pip install python-dotenv`.

///

### O arquivo `.env` { #the-env-file }

Você poderia ter um arquivo `.env` com:

```bash
ADMIN_EMAIL="******@****.***"

func (writer *messageWriter) Finish(bytesScanned, bytesProcessed int64) error {
	select {
	case <-writer.doneCh:
		return fmt.Errorf("messageWriter is done")
	default:
		writer.finBytesScanned = bytesScanned
		writer.finBytesProcessed = bytesProcessed
		close(writer.payloadCh)
		// Wait until the `start` go-routine is done.
		<-writer.doneCh
		return nil
	}
}

		}

		if !done {
			// Drain channel.
			for range s.responses {
			}
		}
	}()
	doneCh := s.ctx.Done()
	for {
		select {
		case <-doneCh:
			if err := context.Cause(s.ctx); !errors.Is(err, errStreamEOF) {
				return err
			}
			// Fall through to be sure we have returned all responses.
			doneCh = nil
		case resp, ok := <-s.responses:
			if !ok {
				done = true
				return nil
			}

这种做法相当常见，有一个名称，这些环境变量通常放在一个名为 `.env` 的文件中，该文件被称为“dotenv”。

/// tip

以点 (`.`) 开头的文件是 Unix-like 系统（如 Linux 和 macOS）中的隐藏文件。

但是，dotenv 文件实际上不一定要具有确切的文件名。

///

Pydantic 支持使用外部库从这些类型的文件中读取。您可以在<a href="https://docs.pydantic.dev/latest/concepts/pydantic_settings/#dotenv-env-support" class="external-link" target="_blank">Pydantic 设置: Dotenv (.env) 支持</a>中阅读更多相关信息。

### El archivo `.env` { #the-env-file }

Podrías tener un archivo `.env` con:

```bash
ADMIN_EMAIL="******@****.***"

		for i := range last {
			entry := lastN[(cnt+i)%last]
			if (entry == log.Info{}) {
				continue
			}
			select {
			case subCh <- entry:
			case <-doneCh:
				return nil
			}
		}
	}
	return sys.pubsub.Subscribe(madmin.LogMaskAll, subCh, doneCh, filter)
}

// Init if HTTPConsoleLoggerSys is valid, always returns nil right now
func (sys *HTTPConsoleLoggerSys) Init(_ context.Context) error {
	return nil
