高级 API 索引 ¶

This page lists all high-level async/await enabled asyncio APIs.

Tasks ¶

Utilities to run asyncio programs, create Tasks, and await on multiple things with timeouts.

`run()`	Create event loop, run a coroutine, close the loop.
`create_task()`	Start an asyncio Task.
`await` `sleep()`	Sleep for a number of seconds.
`await` `gather()`	Schedule and wait for things concurrently.
`await` `wait_for()`	Run with a timeout.
`await` `shield()`	Shield from cancellation.
`await` `wait()`	Monitor for completion.
`current_task()`	Return the current Task.
`all_tasks()`	Return all tasks for an event loop.
`Task`	Task object.
`to_thread()`	Asychronously run a function in a separate OS thread.
`run_coroutine_threadsafe()`	Schedule a coroutine from another OS thread.
`for in` `as_completed()`	Monitor for completion with a `for` loop.

范例

Queues should be used to distribute work amongst multiple asyncio Tasks, implement connection pools, and pub/sub patterns.

范例

Utilities to spawn subprocesses and run shell commands.

`await` `create_subprocess_exec()`	Create a subprocess.
`await` `create_subprocess_shell()`	Run a shell command.

范例

High-level APIs to work with network IO.

`await` `open_connection()`	Establish a TCP connection.
`await` `open_unix_connection()`	Establish a Unix socket connection.
`await` `start_server()`	Start a TCP server.
`await` `start_unix_server()`	Start a Unix socket server.
`StreamReader`	High-level async/await object to receive network data.
`StreamWriter`	High-level async/await object to send network data.

范例

Threading-like synchronization primitives that can be used in Tasks.

范例

`asyncio.TimeoutError`	Raised on timeout by functions like `wait_for()` . Keep in mind that `asyncio.TimeoutError` is unrelated to the built-in `TimeoutError` 异常。
`asyncio.CancelledError`	Raised when a Task is cancelled. See also `Task.cancel()` .
