Angenommen, Sie haben ein Frontend, das in Ihrem Browser unter `http://localhost:8080` läuft, und dessen JavaScript versucht, mit einem Backend zu kommunizieren, das unter `http://localhost` läuft (da wir keinen Port angegeben haben, geht der Browser vom Default-Port `80` aus).

  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

This tells Traefik to listen on port 9999 and to use another file `routes.toml`.

/// tip

We are using port 9999 instead of the standard HTTP port 80 so that you don't have to run it with admin (`sudo`) privileges.

///

Now create that other file `routes.toml`:

```TOML hl_lines="5  12  20"

    protected void setUp() throws Exception {
        super.setUp();

        final int port = 4443;
        logger.info("Creating {}", IMAGE_NAME);
        gcsServer = new GenericContainer<>(IMAGE_NAME)//
                .withExposedPorts(port)//
                .withCommand("-scheme", "http", "-port", String.valueOf(port), "-external-url", "http://localhost:" + port)//
                .waitingFor(Wait.forHttp("/storage/v1/b")//

     * @param tc context to use
     */
    public Handler(final CIFSContext tc) {
        this.transportContext = tc;
    }

    /**
     * Returns the default HTTP port.
     *
     * @return An <code>int</code> containing the default HTTP port.
     */
    @Override
    protected int getDefaultPort() {
        return DEFAULT_HTTP_PORT;
    }

    @Override

            if (queryBuilder != null) {
                builder.setQuery(queryBuilder);
            }
            _conditionQuery.getFieldSortBuilderList().forEach(sort -> {
                builder.addSort(sort);
            });
        }

        if (_conditionAggregation != null) {
            _conditionAggregation.getAggregationBuilderList().forEach(builder::addAggregation);
        }

所以，下面这部分代码才会运行：

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

---

如果你是导入这个模块（文件）就不会这样。

因此，如果你的另一个文件 `importer.py` 像这样：

```Python
from myapp import app

# Some more code
```

在这种情况下，`myapp.py` 内部的自动变量不会有值为 `"__main__"` 的变量 `__name__`。

所以，下面这一行不会被执行：

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

/// info

	PHYS_DIR=$(pwd -P)
	RESULT=$PHYS_DIR/$TARGET_FILE
	echo $RESULT
}

## FIXME:
## In OSX, 'sort -V' option does not exist, hence
## we have our own version compare function.
## Once OSX has the option, below function is good enough.
##
## check_minimum_version() {
##     versions=($(echo -e "$1\n$2" | sort -V))
##     return [ "$1" == "${versions[0]}" ]
## }
##
check_minimum_version() {

            if (queryBuilder != null) {
                builder.setQuery(queryBuilder);
            }
            _conditionQuery.getFieldSortBuilderList().forEach(sort -> {
                builder.addSort(sort);
            });
        }

        if (_conditionAggregation != null) {
            _conditionAggregation.getAggregationBuilderList().forEach(builder::addAggregation);
        }

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

이 실행됩니다.

---

해당 모듈(파일)을 가져오면 이런 일이 발생하지 않습니다

그래서 다음과 같은 다른 파일 `importer.py`가 있는 경우:

```Python
from myapp import app

# Some more code
```

이 경우 `myapp.py` 내부의 자동 변수에는 값이 `"__main__"`인 변수 `__name__`이 없습니다.

따라서 다음 행

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

은 실행되지 않습니다.
