JS 与 Pyppeteer 操作 Cookies
部分网站需要cookies才能显示特定信息，比如不登录的情况下看不到https://github.com/smile365的邮箱信息。
用JavaScript设置和获取网站的cookies
用chrome打开网站，按f12点击console，然后输入代码
// 获取cookies
document.cookie
同理可以用JavaScript设置cookies
// 设置cookeis
Cookies ="_octo=GH1.1.1911316843.1574215196; _ga=GA1.2.86110170.1574215236; _device_id=26f4400b5e70fff5b84f47da276ffe20; tz=Asia%2FShanghai; _gat=1; has_recent_activity=1; user_session=zORKjgUUZSzRcxjNm8BMHvEmQcMLLiG3dbPET-3NpGTRSB0R; __Host-user_session_same_site=zORKjgUUZSzRcxjNm8BMHvEmQcMLLiG3dbPET-3NpGTRSB0R; logged_in=yes; dotcom_user=sxy91;"
c = Cookies.split(";")
for(var i in c){
document.cookie = c[i].trim(); // 需要"name=value"的字符串形式
}
用pyppeteer和chromium设置cookies
pyppeteer是一个python库，代码如下：
import asyncio
from pyppeteer import launch
Cookies ="_octo=GH1.1.1911316843.1574215196; _ga=GA1.2.86110170.1574215236; _device_id=26f4400b5e70fff5b84f47da276ffe20; tz=Asia%2FShanghai; _gat=1; has_recent_activity=1; user_session=zORKjgUUZSzRcxjNm8BMHvEmQcMLLiG3dbPET-3NpGTRSB0R; __Host-user_session_same_site=zORKjgUUZSzRcxjNm8BMHvEmQcMLLiG3dbPET-3NpGTRSB0R; logged_in=yes; dotcom_user=sxy91;"
async def test_cookies():
browser = await launch(devtools=True, args=['--no-sandbox'])
page = await self.browser.newPage()
for c in Cookies.split(";"):
v = c.split("=")
ck = {"name":v[0].strip(),"value":v[1].strip(),'domain':'.github.com'}
await page.setCookie(ck)
await page.goto('https://sxy91.com/post/javscript',{'timeout':60*1000})
await asyncio.sleep(100)
def test():
asyncio.get_event_loop().run_until_complete(test_cookies())
if __name__ == '__main__':
test()
若出现错误：
pyppeteer.errors.NetworkError: Protocol error (Network.deleteCookies): At least one of the url and domain needs to be specified
