### Hey API { #hey-api }

Depois que tivermos uma aplicação FastAPI com os modelos, podemos usar o Hey API para gerar um cliente TypeScript. A forma mais rápida é via npx.

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

Isso gerará um SDK TypeScript em `./src/client`.

@Deprecated
public class StringSearchModelInterpolator extends AbstractStringBasedModelInterpolator {
    private static final Map<Class<?>, InterpolateObjectAction.CacheItem> CACHED_ENTRIES =
            new ConcurrentHashMap<>(80, 0.75f, 2);
    // Empirical data from 3.x, actual =40

    private interface InnerInterpolator {
        String interpolate(String value);
    }

    @Override
    public Model interpolateModel(

Una vez que tenemos una app de FastAPI con los modelos, podemos usar Hey API para generar un cliente de TypeScript. La forma más rápida de hacerlo es con npx.

```sh
npx @hey-api/openapi-ts -i http://localhost:8000/openapi.json -o src/client
```

Esto generará un SDK de TypeScript en `./src/client`.

Se o cliente tentar ir para `/items`, por padrão, ele seria redirecionado para `/items/`.

Mas antes de definir a opção de linha de comando `--forwarded-allow-ips`, poderia redirecionar para `http://localhost:8000/items/`.

Mas talvez sua aplicação esteja hospedada em `https://mysuperapp.com`, e o redirecionamento deveria ser para `https://mysuperapp.com/items/`.

      <match value="M.K." type="string" offset="1080"/>
      <match value="M!K!" type="string" offset="1080"/>
      <match value="FLT4" type="string" offset="1080"/>
      <match value="FLT8" type="string" offset="1080"/>
      <match value="4CHN" type="string" offset="1080"/>
      <match value="6CHN" type="string" offset="1080"/>
      <match value="8CHN" type="string" offset="1080"/>

            byte[] responseData = createValidCopyChunkResponse(8, 16384, 131072);
            System.arraycopy(responseData, 0, buffer, 20, responseData.length);

            int bytesDecoded = response.decode(buffer, 20, 80);

            // Should always return 12 bytes (3 x int4)
            assertEquals(12, bytesDecoded);
            assertEquals(8, response.getChunksWritten());

但这个乱码无法转换回传入的密码。

##### 为什么使用密码哈希

原因很简单，假如数据库被盗，窃贼无法获取用户的明文密码，得到的只是哈希值。

这样一来，窃贼就无法在其它应用中使用窃取的密码，要知道，很多用户在所有系统中都使用相同的密码，风险超大。

#### 关于 `**user_dict`

`UserInDB(**user_dict)` 是指：

*直接把 `user_dict` 的键与值当作关键字参数传递，等效于：*

```Python
UserInDB(
    username = user_dict["username"],
    email = user_dict["email"],

    typer.echo("This is here only to preview a site with translations already built.")
    typer.echo("Make sure you run the build-all command first.")
    os.chdir("site")
    server_address = ("", 8008)
    server = HTTPServer(server_address, SimpleHTTPRequestHandler)
    typer.echo("Serving at: http://127.0.0.1:8008")
    server.serve_forever()


@app.command()
def live(
    lang: str = typer.Argument(

    server.listener.assertClosing(1000, "Bye!")
    server.webSocket!!.finishReader()
    server.listener.assertClosed(1000, "Bye!")
  }

  @Test
  fun emptyCloseInitiatesShutdown() {
    server.sink.write("8800".decodeHex()).emit() // Close without code.
    client.processNextFrame()
    client.listener.assertClosing(1005, "")
    client.webSocket!!.finishReader()
    assertThat(client.webSocket!!.close(1000, "Bye!")).isTrue()

        }

        @Test
        @DisplayName("Should handle boundary conditions")
        void testBoundaryConditions() {
            // Test with exactly aligned data
            request.setData(new byte[8], 0, 8); // 8-byte aligned
            assertEquals(((Smb2Constants.SMB2_HEADER_LENGTH + 48 + 8 + 7) / 8) * 8, request.size());

            // Test with unaligned data
