Connect middleware session and cookie usage sharing _ node. js

Today, the elephant brother used the connect session and cookie, and it feels quite helpful. Share it with me (there are a lot of pitfalls in it, the document is too vague, and it took a lot of time ). Connect is a node middleware (middleware) framework. Specific not table, see the official website to introduce http://www.senchalabs.org/connect/

Under app. js configuration (must be placed in app. use (routes)

The Code is as follows:

Var connect = require ("connect ");
App. use (connect. cookieParser ());
App. use (connect. session ({secret: 'jiami ', cookie: {maxAge: 60*60*24*1000 }}));

Then use

The Code is as follows:

// Set
Req. session. username = "sess_username ";
Req. session. password = "sess_admin ";
Req. session. your = {username: "sess_name", password: "sess_pwd "};
// Use
Console. log (req. session. username );
Console. log (req. session. your );

Other methods

The Code is as follows:

// Cancel the session
Req. session. destroy (function (err ){
Console. log (err );
})
// Regenerate the sid
Req. session. regenerate (function (err ){
Console. log (err );
});

After the session is set, we can see that there is a sid in the cookie to record the session ID.

Print req. cookies and req. session objects

The Code is as follows:

Console. log (req. cookies );
Console. log (req. session );

We can see that the session is connected to the client by saving a connect. sid, but the session is stored in the memory.

2, cookie, the official documentation :( http://www.senchalabs.org/connect/cookieParser.html this document pitted me for a whole day), not to mention the table, the following example is a brother to try out, because the document did not write the use method

Set

The Code is as follows:

// Set cookie
Res. cookie ("user", {username: "cookie_name", password: "cookie_pwd"}, {maxAge: 60*60*24*1000, httpOnly: true, path: '/'});
Res. cookie ("msg", "username or password cannot be blank", {maxAge: 60*60*24*1000 });

Delete

The Code is as follows:

Res. cookie ("msg", "username or password cannot be blank", {maxAge: 0 });
