val a3 = client.newCall(newRequest("http://a/3"))
    val a4 = client.newCall(newRequest("http://a/4"))
    val t1 = makeSynchronousCall(a1)
    val t2 = makeSynchronousCall(a2)

    // We created 4 calls and started 2 of them. That's 2 running calls and 0 queued.

你可以通过 `FastAPI` 使用所有的 [Starlette](https://www.starlette.dev/) 的功能。

### 步骤 2：创建一个 `FastAPI`「实例」 { #step-2-create-a-fastapi-instance }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[3] *}

这里的变量 `app` 会是 `FastAPI` 类的一个「实例」。

这个实例将是创建你所有 API 的主要交互对象。

### 步骤 3：创建一个*路径操作* { #step-3-create-a-path-operation }

#### 路径 { #path }

这里的「路径」指的是 URL 中从第一个 `/` 起的后半部分。

所以，在一个这样的 URL 中：

```

  return th;
}

TFE_TensorHandle* TestVariable(TFE_Context* ctx, float value,
                               const tensorflow::string& device_name) {
  TF_Status* status = TF_NewStatus();
  // Create the variable handle.
  TFE_Op* op = TFE_NewOp(ctx, "VarHandleOp", status);
  if (TF_GetCode(status) != TF_OK) return nullptr;
  TFE_OpSetAttrType(op, "dtype", TF_FLOAT);
  TFE_OpSetAttrShape(op, "shape", {}, 0, status);

                "application/soap+xml", //
                "application/atom+xml", //
                "image/svg+xml" //
        };

        for (String mimeType : mimeTypesWithPlus) {
            // Create proper escaped pattern
            String escapedPattern = mimeType.replace("+", "\\+");

            // Verify escaped pattern matches

    private final int initialReceiveBuffers = 64;
    private final int sendBufferSize = 65536; // 64KB
    private final int receiveBufferSize = 65536; // 64KB

    /**
     * Create new RDMA buffer manager
     *
     * @param provider RDMA provider for memory registration
     */
    public RdmaBufferManager(RdmaProvider provider) {
        this.provider = provider;

    private static final Logger log = LoggerFactory.getLogger(TcpRdmaConnection.class);

    private SocketChannel socketChannel;
    private Socket socket;

    /**
     * Create new TCP RDMA connection
     *
     * @param remote remote socket address
     * @param local local socket address, may be null
     */
    public TcpRdmaConnection(InetSocketAddress remote, InetSocketAddress local) {

        assertEquals(sourceData.length, result);
        assertArrayEquals(sourceData, smallOutputBuffer);
    }

    @Test
    void testReadDataWireFormatExceedsBufferSize() {
        // Create a response with small output buffer
        byte[] smallOutputBuffer = new byte[5];
        TransCallNamedPipeResponse smallResponse = new TransCallNamedPipeResponse(mockConfig, smallOutputBuffer);

    }

    @Test
    @DisplayName("parseURL with null spec throws NullPointerException")
    void testParseURL_NullSpec() throws MalformedURLException {
        // Arrange: create a URL object to mutate via parseURL (same package allows calling protected method)
        Handler handler = newHandler();
        URL url = new URL(null, "smb://server/share", handler);

        // Act & Assert

Mais c'est la façon la plus simple de se concentrer sur la partie serveur des WebSockets et d'avoir un exemple fonctionnel :

{* ../../docs_src/websockets_/tutorial001_py310.py hl[2,6:38,41:43] *}

## Créer un `websocket` { #create-a-websocket }

Dans votre application **FastAPI**, créez un `websocket` :

{* ../../docs_src/websockets_/tutorial001_py310.py hl[1,46:47] *}
