'async with' outside async function 错误表明你尝试在一个非异步函数(即没有使用 async 关键字定义的函数)中使用 async with 语句。async with 是Python 中用于异步上下文管理的语法,它要求必须在异步函数内部使用,因为 async with 会暂停和恢复执行,这是异步编程的核心特性之一。

Python使用aiohttp的时候报错SyntaxError: 'async with' outside async function 百度了一圈没有找到答案,因为我是按照官网文档打的,报错了,头大,还以为是包被我改坏了 结果,回看以前的代码,发现是因为,这个async with xxx as xxx:这个结构必须放在async def xxx():这样子的函数里面才行。 上代码 async def mai...

‘await’ outside function asyncio asyncio 是用来编写并发代码的库,被用作多个提供高性能 Python 异步框架的基础,包括网络和网站服务,数据库连接库,分布式任务队列等等。 asyncio 往往是构建 IO 密集型和高层级 结构化 网络代码的最佳选择。 run 该函数用来运行最高层级的入口点,如下面的main函数,并返回main函数...
async function f(){ // response will evaluate as the resolved value of the promise const response = await rp('http://example.com/'); console.log(response); } // We can't use await outside of async function. // We need to use then callbacks ... f().then(() => console.log...
asyncfunctionfoo(){returnnewPromise(function(resolve, reject){setTimeout(function(){resolve('hello world!') },3000) }) }foo() ---output---Promise{<pending>} 这时候Javascript引擎将不再进一步封装。这种情况下,函数是否用async关键字修饰是无关紧要的,但为代码便于阅读和理解起见,建议仍然加上这一关...
