scrapy如何获取response请求头中的多个set-cookie

无敌的白金之星 2018-10-17 01:50:20

如题，这是response.headers：
{b'Content-Type': [b'text/html; charset=utf-8'], b'Cache-Control': [b'private, no-cache, no-store, must-revalidate'], b'Pragma': [b'no-cache'], b'Expires': [b'Sat, 01 Jan 2000 00:00:00 GMT'], b'Vary': [b'Accept-Language, Cookie, Accept-Encoding
'], b'Content-Language': [b'en'], b'Date': [b'Wed, 17 Oct 2018 05:39:47 GMT'], b'Strict-Transport-Security': [b'max-age=60'], b'X-Frame-Options': [b'SAMEORIGIN'], b'Content-Security-Policy': [b"report-uri https://www.instagram.com/security/csp_

其中显示的set-cookie为：
b'Set-Cookie': [b'rur=FRC; Domain=.instagram.com; HttpOnly; Path=/; Secure', b'mid=W8bLIgALAAF7VCTnsHdOeJAA7IzL; Domain=.instagram.com; expires=Sat, 14
-Oct-2028 05:39:47 GMT; Max-Age=315360000; Path=/; Secure', b'urlgen="{\\"140.82.22.53\\": 20473}:1gCeYd:dhTaKnksZ3Yo7uF5yU_9v6IVs-g"; Domain=.instagram.com; HttpOnly; Path=/; Secure', b'mcd=3; Domain=.instagram.com; expires=Sat, 14-Oct-2028 05

但是用response.headers['set-cookie']获取的内容只有：
b'csrftoken=0XLdwkUkSII40ea8N4BR19B3zWuFSLg0; Domain=.instagram.com; expires=Wed, 16-Oct-2019 05:39:47 GMT; Max-Age=31449600; Path=/; Secure'

要怎样才能获取到全部？

附上chrome浏览器显示的set-cookie情况：
set-cookie: rur=FRC; Domain=.instagram.com; HttpOnly; Path=/; Secure
set-cookie: urlgen="{\"139.180.218.220\": 20473\054 \"140.82.22.53\": 20473}:1gCeSl:J3gpMvE673WW0a8KXOPMl_D3A6k"; Domain=.instagram.com; HttpOnly; Path=/; Secure
set-cookie: csrftoken=is3aHClgPzEXi2bIzYGqlmbnqQrxmvrr; Domain=.instagram.com; expires=Wed, 16-Oct-2019 05:33:43 GMT; Max-Age=31449600; Path=/; Secure
