Multiple files can be added. Files ending in '.zip' will be searched
for 'xl.meta' files. Wildcards are accepted: 'testdir/*.txt' will compress
all files in testdir ending with '.txt', directories can be wildcards
as well. 'testdir/*/*.txt' will match 'testdir/subdir/b.txt', double stars
means full recursive. 'testdir/**/xl.meta' will search for all xl.meta
recursively.

* `docs`: Docs
    * Changes in docs. This includes updating the docs, fixing typos. But it doesn't include changes to translations.

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

在底层，`open("./somefile.txt")`创建了一个被称为"上下文管理器"的对象。

当 `with` 代码块结束时，它会确保关闭文件，即使发生了异常也是如此。

当你使用 `yield` 创建一个依赖项时，**FastAPI** 会在内部将其转换为上下文管理器，并与其他相关工具结合使用。

### 在使用 `yield` 的依赖项中使用上下文管理器

import org.junit.rules.TemporaryFolder;

/**
 * @author wyukawa

public class PropertiesUtilTest {

    URL url = ResourceUtil.getResource(getClass().getName().replace('.', '/') + ".txt");

    File inputFile = URLUtil.toFile(url);

    /**
     *
     */
    @Rule
    public TemporaryFolder tempFolder = new TemporaryFolder();

    /**
     * @see org.junit.rules.ExpectedException

该示例中，信息会在响应发出 *之后* 被写到 `log.txt` 文件。

如果请求中有查询，它将在后台任务中写入日志。

然后另一个在 *路径操作函数* 生成的后台任务会使用路径参数 `email` 写入一条信息。
