从请求标头中获取特定的cookie（快速）

Question

I came across an issue today with express, assume we set several cookies, when I use request.headers only one cookie is returned:

cookie: 'userSession=123'

for example, not only can't I use request.headers.cookie as it is unreliable (users can have several cookies set), but I can't parse it into a JSON object (this is invalid json) nor can I select this cookie specifically, which leads to a subquestion, is this how we get cookies from express response, through headers?

Answer 1

您可以从$ npm install cookie-parser使用cookieParser() $ npm install cookie-parser
