儘管如此，FastAPI 仍從 Requests 得到了不少啟發。

**Requests** 是一個「與 API 互動」（作為用戶端）的程式庫，而 **FastAPI** 是一個「建立 API」（作為伺服端）的程式庫。

它們大致位於相反兩端，彼此互補。

Requests 設計非常簡單直觀、容易使用，且有合理的預設值。同時它也非常強大且可自訂。

因此，如其官網所言：

> Requests is one of the most downloaded Python packages of all time

用法非常簡單。例如，發出一個 `GET` 請求，你會寫：

```Python
response = requests.get("http://example.com/some/url")
```

相對地，FastAPI 的 API 路徑操作（path operation）可能像這樣：

     * ensure that completed write operations performed by other threads are noticed. For most
     * purposes, the "count" field, tracking the number of elements, serves as that volatile
     * variable ensuring visibility. This is convenient because this field needs to be read in many
     * read operations anyway:
     *
     * - All (unsynchronized) read operations must first read the "count" field, and should not

// sendUpdate() should be called on a regular basis when the newCache contains more recent total than previously.
// May or may not send an update upstream.
func (f *folderScanner) sendUpdate() {
	// Send at most an update every minute.
	if f.updates == nil || time.Since(f.lastUpdate) < time.Minute {
		return
	}
	if flat := f.updateCache.sizeRecursive(f.newCache.Info.Name); flat != nil {
		select {
