Das war's schon.

**Zwei Zeilen**.

Und sie hat die gleiche Form und Struktur wie alle Ihre *Pfadoperation-Funktionen*.

Sie können sie sich als *Pfadoperation-Funktion* ohne den „Dekorator“ (ohne `@app.get("/some-path")`) vorstellen.

Und sie kann alles zurückgeben, was Sie möchten.

In diesem Fall erwartet diese Abhängigkeit:

* Einen optionalen Query-Parameter `q`, der ein `str` ist.

* Otomatik olarak data modelinin <a href="http://json-schema.org/" class="external-link" target="_blank"><strong>JSON...

```Python hl_lines="2"

/// note | 注意

你只能在 `async def` 建立的函式內使用 `await`。

如果你使用的是第三方函式庫並且它需要與某些外部資源（例如資料庫、API、檔案系統等）進行通訊，但不支援 `await`（目前大多數資料庫函式庫都是這樣），在這種情況下，你可以像平常一樣使用 `def` 宣告*路徑操作函式*，如下所示：

```Python hl_lines="2"
@app.get('/')
def results():
    results = some_library()

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

/// note

你只能在被 `async def` 创建的函数内使用 `await`

///

如果你正在使用一个第三方库和某些组件（比如：数据库、API、文件系统...）进行通信，第三方库又不支持使用 `await` （目前大多数数据库三方库都是这样），这种情况你可以像平常那样使用 `def` 声明一个路径操作函数，就像这样：

```Python hl_lines="2"
@app.get('/')
def results():
    results = some_library()

        pageNumber.ifPresent(num -> {
            stopwordsPager.setCurrentPageNumber(pageNumber.get());
        }).orElse(() -> {
            stopwordsPager.setCurrentPageNumber(0);
        });
        return asHtml(path_AdminDictStopwords_AdminDictStopwordsJsp).renderWith(data -> {
            searchPaging(data, form);

    }

        } else if (queryBuilderList.size() == 1) {
            return queryBuilderList.get(0);
        }
        BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();
        queryBuilderList.forEach(query -> {
            boolQuery.must(query);
        });
        return boolQuery;
    }

            final LaJobRuntime jobRuntime = ComponentUtil.getJobHelper().getJobRuntime();
            if (jobRuntime != null) {
                final ScheduledJob job = (ScheduledJob) jobRuntime.getParameterMap().get(Constants.SCHEDULED_JOB);
                if (job != null) {
                    prop.setProperty("job.runtime.id", job.getId());
                    prop.setProperty("job.runtime.name", job.getName());
                }

        return next;
      }
      next = getNext(entry);
    }
    return -1;
  }
