我们正在使用虚构的请求首部来简化此示例。

但在实际情况下，使用集成的[安全性实用工具](security/index.md){.internal-link target=_blank}会得到更好的效果。

## 其他使用 `APIRouter` 的模块

假设你在位于 `app/routers/items.py` 的模块中还有专门用于处理应用程序中「项目」的端点。

你具有以下*路径操作*：

* `/items/`
* `/items/{item_id}`

  // - message: The validation failure message string
  // - policy: The resource name of the ValidatingAdmissionPolicy
  // - binding: The resource name of the ValidatingAdmissionPolicyBinding
  // - expressionIndex: The index of the failed validations in the ValidatingAdmissionPolicy
  // - validationActions: The enforcement actions enacted for the validation failure
  // Example audit annotation:

		p = p[len("../"):]
	}

	return p
}

func (r *Reader) initFileList() {
	r.fileListOnce.Do(func() {
		// files and knownDirs map from a file/directory name
		// to an index into the r.fileList entry that we are
		// building. They are used to mark duplicate entries.
		files := make(map[string]int)
		knownDirs := make(map[string]int)

The main web server to run **FastAPI** applications.

You can also use the `--workers` command line option to have an asynchronous multi-process server.

Check more details in the [Deployment](deployment/index.md){.internal-link target=_blank} section.

## Benchmarks and speed

// [Reader.ReadBytes] or ReadString instead.
// ReadSlice returns err != nil if and only if line does not end in delim.
func (b *Reader) ReadSlice(delim byte) (line []byte, err error) {
	s := 0 // search start index
	for {
		// Search buffer.
		if i := bytes.IndexByte(b.buf[b.r+s:b.w], delim); i >= 0 {
			i += s
			line = b.buf[b.r : b.r+i+1]
			b.r += i + 1
			break
		}

		// Pending error?

Hauptwebserver zum Ausführen von **FastAPI**-Anwendungen.

Sie können ihn mit Gunicorn kombinieren, um einen asynchronen Multiprozess-Server zu erhalten.
