## 加入更多驗證 { #add-more-validations }

你也可以加入 `min_length` 參數：

{* ../../docs_src/query_params_str_validations/tutorial003_an_py310.py hl[10] *}

## 加入正規表示式 { #add-regular-expressions }

你可以定義參數必須符合的 <dfn title="正規表示式（regex、regexp）是一組用於定義字串搜尋樣式的字元序列。">regular expression</dfn> `pattern`：

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

這個特定的正規表示式樣式會檢查收到的參數值是否：

- `^`：以後續的字元開頭，前面不能有其他字元。

		// observations. This is to test the channel based
		// synchronization used internally.
		<-ticker.C
		ttfbHist.With(prometheus.Labels{"api": obs.label}).Observe(obs.val)
	}

	// Accumulate regular-cased API label metrics for 'PutObject' for deeper verification
	metrics := getHistogramMetrics(ttfbHist, getBucketTTFBDistributionMD(), false, false)
	capitalPutObjects := make([]MetricV2, 0, len(histBuckets)+1)

signs the other party's chain.

Well-Known Certificate Authorities
----------------------------------

In these examples we've prearranged which root certificates to trust. But for regular HTTPS on the
Internet this set of trusted root certificates is usually provided by default by the host platform.
Such a set typically includes many root certificates from well-known certificate authorities like
