Async / Await usage with asyncio to retrieve urls in parallel

[lukee]

I sure would love to post my experiments, but I'm really struggling to put it all together. I don't even know where to start. What I want seems fairly simple (just by looking at the sync version), and I'm new to python so I'm really in pain to make all of this work. In the end I just want a async getResults() function that can be called from elsewhere just as if it were a sync getResults().

From what I understand of your answers, I have no choice but to use the aiohttp. So the other pieces of code are irrelevant.

In the last example you're giving, it just prints the result, whereas I want to return it as a dictionary url -> response, and it doesn't handle a loop.

Here is what I've tried, but I don't know how wrong I am :

async def getResultsAsync(urls):
    async def getResultAsync(url):
        async with aiohttp.ClientSession() as session:
            resp = await session.get(url)
            res = url, await resp.json()
        return res
    return dict(await asyncio.gather(*[getResultAsync(url) for url in urls]))

def getResults(urls):
    return asyncio.run(getResultsAsync(url))
