使用同一个ClientSession获取多个不同的url

Question

通常我在请求中编写代码，因此我对 aiohttp 没有太多经验。但由于请求被阻止，我必须使用 aiohttp。

那么我的代码在请求中是什么样子的：

#Account gen code is here using requests 

r = requests.get(product_link)

watch_link = soup(r.text, "html.parser").find("div", {"id": "vi-atl-lnk"}).a["href"]

r = requests.get(watch_link)
r = requests.get(watch_link)

所以它的作用是转到 Ebay 列表，然后使用 BS4 抓取该列表源代码中的手表 link。然后它使用 GET 请求将列表添加到观察列表。 add to watch list 必须有2个GET请求link，否则不会真正添加。

那是在请求中，但现在我需要在 aiohttp 中编写它。我得到的最接近的是：

session = aiohttp.ClientSession()

async def main():
    #Account gen code is here using aiohttp and session 
    async with session.get(product_link) as resp:
         r = await resp.text()
         watch_link = soup(r, "html.parser").find("div", {"id": "vi-atl-lnk"}).a["href"]
    async with session.get(watch_link) as respp:   
         time.sleep(.1)
    async with session.get(watch_link) as resp:   
         time.sleep(.1)

 loop = asyncio.get_event_loop()
 loop.run_until_complete(main())

我试过了，它对我来说运行，但它没有将项目添加到监视列表中。上面的代码（未显示，因为它与此问题无关 AFAIK）运行完美地创建了帐户。但是当涉及到监视列表位时，它就不起作用了。这可能是什么原因？

我试了很多次，终于发现cookie有问题。并且您需要将代码更改为 aiohttp.ClientSession(headers=headers)。顺便说一句，真相可能在 cookies 中，其中将 ; 转换为 3

Not aiohttp.ClientSession(headers=headers,cookies=cookies)

上面是我整理的代码。

import aiohttp
import asyncio
from bs4 import BeautifulSoup as soup

product_link = ""

cookies = {"Cookie":"_ga=GA1.2.808...."}
headers = {"Connection": "keep-alive"}
headers.update(cookies)

async def main():
    #Account gen code is here using aiohttp and session 
    async with aiohttp.ClientSession(headers=headers) as sessions:

        async with sessions.get(product_link) as resp:
            r = await resp.text()
            watch_link = soup(r, "lxml").find("div", {"id": "vi-atl-lnk"}).a.get("href")
            print(watch_link)

        async with sessions.get(watch_link) as resp:
            pass

        async with sessions.get(watch_link) as resp:
            pass


loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Answer 2

        session = aiohttp.ClientSession()
        async with session.post(link,data=payload,headers=headers) as resp:
            print("Created account with email " + random_catchall)
        async with session.get(product_link,headers=headers) as response:
            r = await response.text()
            watch_link = soup(r, "html.parser").find("div", {"id": "vi-atl-lnk"}).a["href"]

            print("Connected to product")

        async with session.get(watch_link,headers=headers) as respp:
            print("Sucessfully added to watchlist")
        async with session.get(watch_link,headers=headers) as respp:
            print("Added to watch list")


        await session.close()

这最终对我有用。不需要 cookie 或任何类似的东西:)
