### Kiểm tra

Mở trình duyệt của bạn tại <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.

Bạn sẽ thấy một JSON response:

```JSON
{"item_id": 5, "q": "somequery"}
```

Bạn đã sẵn sàng để tạo một API như sau:

* Nhận HTTP request với _đường dẫn_ `/` và `/items/{item_id}`.

	resp, err := h.client.Do(req)
	if err != nil {
		return fmt.Errorf("%s returned '%w', please check your endpoint configuration", h.Endpoint(), err)
	}

	// Drain any response.
	xhttp.DrainBody(resp.Body)

	if resp.StatusCode >= 200 && resp.StatusCode <= 299 {
		// accepted HTTP status codes.
		return nil
	} else if resp.StatusCode == http.StatusForbidden {

	if o.Marker < o.Prefix {
		o.Marker = ""
	}

	// Marker is set validate pre-condition.
	if o.Marker != "" && o.Prefix != "" {
		// Marker not common with prefix is not implemented. Send an empty response
		if !HasPrefix(o.Marker, o.Prefix) {
			return entries, io.EOF
		}
	}

	// With max keys of zero we have reached eof, return right here.
	if o.Limit == 0 {
		return entries, io.EOF
	}

> Requests - один из самых загружаемых пакетов Python всех времен


Использовать его очень просто. Например, чтобы выполнить запрос `GET`, Вы бы написали:

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

Противоположная *операция пути* в FastAPI может выглядеть следующим образом:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():

// the name displayed in logs and trace to be accurate. The name is extracted
// via reflection.
//
// When **no** flags are passed, the behavior is to trace both headers and body,
// gzip the response and throttle the handler via `maxClients`. Each of these
// can be disabled via the corresponding `s3HFlag`.
//
// CAUTION: for requests involving large req/resp bodies ensure to pass the
