根因分析

await 关键字被用在普通的 def 函数或模块顶层。await 只能在 async def 函数体内使用（或在 IPython/Jupyter 的顶层 await 中）。

English

The await keyword was used in a regular def function or at module top level. await is only valid inside async def bodies (or in top-level await when using IPython/Jupyter).

解决方案

  1. 95% 成功率 
    async def handler():
    data = await fetch()
    return data
  2. 93% 成功率 
    async def main():
    await fetch()
if __name__ == '__main__':
    asyncio.run(main())
  3. 90% 成功率 
    # IPython/Jupyter supports top-level await in cells
await fetch()

无效尝试

常见但无效的做法:

  1. 75% 失败

    If the sync function is itself called from async code, this raises 'This event loop is already running'.

  2. 95% 失败

    Coroutine objects have no result() method; raises AttributeError.
