大佬，按你的弄，又 出现这个问题了

ERROR:    Traceback (most recent call last):
  File "f:\project\Python\Ven\lib\site-packages\apscheduler\schedulers\base.py", line 896, in _create_plugin_instance
    plugin_cls = class_container[alias]
KeyError: 'date'

During handling of the above exception, another exception occurred:

LookupError: No trigger by the name "date" was found

nb

我找到问题了

async def init_scheduler():
    scheduler.configure(**settings.dict())
    print("---------初始化 scheduler --------")
    # schedule test
    # scheduler.add_job(func=init_echo, trigger="date", next_run_time=datetime.now())
    scheduler.start()


# def init_echo():
#     print("---------测试启动任务------ ")

请问一下，这里为什么写了data就出现上门这个问题呢？

运行的代码片段看看

你看下官方文档就很清楚了

func – callable (or a textual reference to one) to run at the given time

trigger (str|apscheduler.triggers.base.BaseTrigger) – trigger that determines when func is called

args (list|tuple) – list of positional arguments to call func with

kwargs (dict) – dict of keyword arguments to call func with

id (str|unicode) – explicit identifier for the job (for modifying it later)

name (str|unicode) – textual description of the job

misfire_grace_time (int) – seconds after the designated runtime that the job is still allowed to be run (or None to allow the job to run no matter how late it is)

coalesce (bool) – run once instead of many times if the scheduler determines that the job should be run more than once in succession

max_instances (int) – maximum number of concurrently running instances allowed for this job

next_run_time (datetime) – when to first run the job, regardless of the trigger (pass None to add the job as paused)

jobstore (str|unicode) – alias of the job store to store the job in

executor (str|unicode) – alias of the executor to run the job with

replace_existing (bool) – True to replace an existing job with the same id (but retain the number of runs from the existing one)

@小小咸鱼YwY: trigger有date, interval, cron可供选择，其实看字面意思也可以知道，date表示具体的一次性任务，interval表示循环任务，cron表示定时任务,我都一次性了你告诉我运行时间是现在,你为什么不直接init_echo(),而且datetime.now()获取的这一刻肯能已经过了
