Nodejs implements cookie

The following code is the code in the initnode framework being written. You may not be able to copy all the codes when implementing cookies.
Cookie implementation mainly refers to sending the header message:
[Javascript]
Res. setHeader ("Set-Cookie", cookieArr );
Res. setHeader ("Set-Cookie", ['username = XXX', 'Age = xxx; path =/foo']); // Note: Multiple cookies must be sent once, multiple calls to this sending header function only take effect for the last time
Complete http setcookie header:
Set-Cookie: customer = huangxp; path =/foo; domain = .ibm.com;
Expires = Wednesday, 19-OCT-05 23:12:40 GMT; [secure]
To implement cookie settings, You need to assemble the above cookie header information. For details, refer to the following code: set_cookie Function
