问题
I am working on a web application and I used this starter kit as base of my project. The problem is that the cookie is not available in server side so I cannot use it for rendering a component in server.
I use react-cookie to save the account data after login
cookie.save('account', accountData)
and retrieve
var account = cookie.load('account')
it when I need it. I see that the cookie is saved into browser and I can use it in client side after the component is loaded but I need it in server side for pre-rendering operations.
So the question is how to achive that? Or, if cookie is not the right approach, what is the best way to do it?
回答1:
Are you using the cookie-parser middleware? From the react-cookie docs:
You can also plug it directly with a Node.js request by adding just before the renderToString:
reactCookie.plugToRequest(req, res);(require the cookieParser middleware)
Express won't parse requests to get the cookie out unless you have some cookie parsing middleware installed and enabled in your Express app.
