`File` est une classe qui hérite directement de `Form`.

Mais souvenez-vous que lorsque vous importez `Query`, `Path`, `File` et d'autres depuis `fastapi`, ce sont en réalité des fonctions qui renvoient des classes spéciales.

FastAPI 会将每个数据块原样交给 `StreamingResponse`，不会尝试将其转换为 JSON 或做类似处理。

### 非 async 的*路径操作函数* { #non-async-path-operation-functions }

你也可以使用常规的 `def` 函数（不带 `async`），并以相同方式使用 `yield`。

### 无需注解 { #no-annotation }

你其实不需要为流式二进制数据声明返回类型注解。

      int diff = 0x0; // bitset for output bits with different values
      int count = 0;
      // originally was 2 * Math.log(...), making it try more times to avoid flakiness issues
      int maxCount = (int) (4 * Math.log(2 * keyBits * hashBits) + 1);
      while (same != 0xffffffff || diff != 0xffffffff) {
        int key1 = rand.nextInt();
        // flip input bit for key2

        String testAddress = "https://search-engine.example.com:9200/path?param=value&other=test";

И всё.

**2 строки.**

И она имеет ту же форму и структуру, что и все ваши *функции обработки пути*.

Можно думать о ней как о *функции обработки пути* без «декоратора» (без `@app.get("/some-path")`).

И она может возвращать что угодно.

В этом случае эта зависимость ожидает:

* Необязательный query-параметр `q` типа `str`.
* Необязательный query-параметр `skip` типа `int`, по умолчанию `0`.
