В этом примере сообщения будут записаны в файл `log.txt` после отправки ответа.

Если в запросе была строка запроса (query), она будет записана в лог фоновой задачей.

Затем другая фоновая задача, созданная в функции‑обработчике пути, запишет сообщение, используя path‑параметр `email`.

## Технические детали { #technical-details }

   `X-Android-Selected-Transport` to read the negotiated transport.


## Version 1.0.2

_2013-05-11_

 * Fix: Remove use of Java 6-only APIs.
 * Fix: Properly handle exceptions from `NetworkInterface` when querying MTU.
 * Fix: Ensure MTU has a reasonable default and upper-bound.


## Version 1.0.1

_2013-05-06_

 * Correct casing of SSL in method names (`getSslSocketFactory`/`setSslSocketFactory`).

### 在「被依賴者」（dependant）中宣告依賴 { #declare-the-dependency-in-the-dependant }

和你在「路徑操作函式」參數上使用 `Body`、`Query` 等方式一樣，針對新參數使用 `Depends`：

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

雖然你在函式參數上使用 `Depends` 的方式和 `Body`、`Query` 等相同，但 `Depends` 的運作方式有點不同。

你只需要傳給 `Depends` 一個參數。

這個參數必須是類似函式的東西。

你不需要直接呼叫它（不要在後面加上括號），只要把它作為參數傳給 `Depends()` 即可。

func (where Where) Build(builder Builder) {
	if len(where.Exprs) == 1 {
		if andCondition, ok := where.Exprs[0].(AndConditions); ok {
			where.Exprs = andCondition.Exprs
		}
	}

	// Switch position if the first query expression is a single Or condition
	for idx, expr := range where.Exprs {
		if v, ok := expr.(OrConditions); !ok || len(v.Exprs) > 1 {
			if idx != 0 {
				where.Exprs[0], where.Exprs[idx] = where.Exprs[idx], where.Exprs[0]

    void testSetQueryFlags() {
        request = new Smb2QueryInfoRequest(mockConfig);
        int testQueryFlags = 0xABCDEF00;

        request.setQueryFlags(testQueryFlags);

        // Verify query flags were set
        Field queryFlagsField;
        try {
            queryFlagsField = Smb2QueryInfoRequest.class.getDeclaredField("queryFlags");
            queryFlagsField.setAccessible(true);

Da mesma forma que você utiliza `Body`, `Query`, etc. Como parâmetros de sua *função de operação de rota*, utilize `Depends` com um novo parâmetro:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

Ainda que `Depends` seja utilizado nos parâmetros da função da mesma forma que `Body`, `Query`, etc, `Depends` funciona de uma forma um pouco diferente.
