如何使用 asyncio.gather 立即解析響應？

Question

async def main():
    uuids = await get_uuids_from_text_file()
    tasks = []
    # create a task for each uuid
    # and add it to the list of tasks
    for uuid in uuids:
        task = asyncio.create_task(make_hypixel_request(uuid))
        tasks.append(task)
    # wait for all the tasks to finish
    responses = await asyncio.gather(*tasks)
    # run the functions to process the data
    for response in responses:
        print(response['success'])
        data2 = await anti_sniper_request(response)
        await store_data_in_json_file(response, data2)
        await compare_stats(response)

# loop the main function
async def main_loop():
    for _ in itertools.repeat([]):
        await main()


# run the loop
loop = asyncio.get_event_loop()
loop.run_until_complete(main_loop())
loop.close()

基本上這是我的代碼函數有非常清晰和解釋性的名稱 make_hypixel_requests 部分我在那里沒有問題，請求立即並行執行，問題是在那之后當“響應中的響應”變得很慢時？ 我如何立即獲得響應並快速循環？ 我會嘗試附加一個 gif。

基本上這是個問題：

Answer 1

原因是因為在等待所有響應返回之后，你在循環中而不是異步地處理它們，因為沒有一個請求似乎相互依賴，等待它們全部完成再處理它們沒有意義，處理這個問題的最好方法是將請求和處理結合起來，例如

async def request_and_process(uuid):
    response = await make_hypixel_request(uuid)
    print(response['success'])
    compare_stats_task = asyncio.create_task(compare_stats(response))
    data2 = await anti_sniper_request(response)
    await asyncio.gather(store_data_in_json_file(response, data2), compare_stats_task)

async def main():
    while True:
        uuids = await get_uuids_from_text_file()
        await asyncio.gather(*map(request_and_process, uuids))

asyncio.run(main())

Answer 2

您可以使用asyncio.wait並在至少完成一項任務時返回，然后繼續等待掛起的任務。 asyncio.wait返回一個包含兩組的元組，第一個包含已完成的任務，第二個包含仍未完成的任務。 您可以調用已完成任務的result方法並獲取其返回值。

async def main():
    uuids = await get_uuids_from_text_file()
    tasks = []
    # create a task for each uuid
    # and add it to the list of tasks
    for uuid in uuids:
        task = asyncio.create_task(make_hypixel_request(uuid))
        tasks.append(task)
    # wait for all the tasks to finish
    while tasks:
        done_tasks, tasks = await asyncio.wait(tasks, return_when=asyncio.FIRST_COMPLETED)
        for done in done_tasks:
            response = done.result()
            print(response['success'])
            data2 = await anti_sniper_request(response)
            await store_data_in_json_file(response, data2)
            await compare_stats(response)
