# 模板

**FastAPI** 支持多种模板引擎。

Flask 等工具使用的 Jinja2 是最用的模板引擎。

在 Starlette 的支持下，**FastAPI** 应用可以直接使用工具轻易地配置 Jinja2。

## 安装依赖项

安装 `jinja2`：

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## 使用 `Jinja2Templates`

* 导入 `Jinja2Templates`
* 创建可复用的 `templates` 对象
* 在返回模板的*路径操作*中声明 `Request` 参数

	if err != nil {
		log.Fatalln(err)
	}

	zipFile, err := os.Create("format.json.zip")
	if err != nil {
		log.Fatalf("failed to create format.json.zip: %v", err)
	}
	defer zipFile.Close()
	fmtZipW := zip.NewWriter(zipFile)
	defer fmtZipW.Close()
	for _, pool := range pools { // for each pool
		setCount, setDriveCount := pool.SetCount, pool.DrivesPerSet
		format := newFormatErasureV3(setCount, setDriveCount)
		format.ID = deploymentID

		// Obvious ASCII ones: \t through \r plus space. Plus two Latin-1 oddballs.
		switch r {
		case ' ', '\t', '\n', '\v', '\f', '\r':
			return true
		case '\u0085', '\u00A0':
			return true
		}
		return false
	}
	// High-valued ones.
	if '\u2000' <= r && r <= '\u200a' {
		return true
	}
	switch r {
	case '\u1680', '\u2028', '\u2029', '\u202f', '\u205f', '\u3000':
		return true
	}
	return false
}
