1. There's a tricky problem today, where you write down blogs that remind yourself and help people who are going to be in trouble. In the Shiro framework, you can login directly in your code with a username password. First looked up on the internet, found this way: Subject CurrentUser = Securityutils.getsubject (); Usernamepasswordtoken token = new Usernamepasswordtoken (Username,password, false,request.getremoteaddr ()); Currentuser.login (

I believe a lot of people will be like me. After token authentication, the message is sent to the subscription number, and no message is returned. Here are some of the solutions I have worked hard to debug: First, token verification: My own write token has been failed to verify, looking for a long time, no bug found. There is no way to use the official sample c

Reprinted link: http://www.jb51.net/article/13756.htm PHP Token design goals: avoid repeated data submission. check whether an external commit matches the action to be executed.

Reference: http://blog.csdn.net/sum_rain/article/details/37085771Token, the most important feature of tokens, is randomness, unpredictable. General hackers or software can not guess out.So, what does token do? What is the principle of it?Tokens are generally used in two places: 1) Prevent duplicate submissions of forms, 2) Anti CSRF attack (cross-site request forgery). Both are based on the principle of the session

The token (token) mechanism of struts is a good solution to the problem of recurring forms, and the rationale is that the server side will compare the token value contained in the request to the token value saved in the current user session to see if the match is made before the incoming request is processed. After the

Here is a simple example of JS using cookies: Cookies are generated when a user logs on: Document.cookie = "id=" +result.data[' id ']+ '; path=/"; Document.cookie = "Name=" +result.data[' name ']+ '; path=/"; Document.cookie = "avatar=" +result.data[' Avatar ']+ '; path=/"; When you use the cookie, you do the following parsing: var cookie = Document.cookie;var Co

Tokens are the way in which values are defined in a blockchain to demarcate financial or digital assets. In Ethereum, tokens use the same standards, which makes it easy to exchange and DAPP support between tokens. What is the ERC20 standard The ERC-20 standard, introduced in November 2015, uses tokens of this rule to show a common and predictable approach. Simply put, any ERC-20 token can be immediately compatible with Ethereum wallets (almost all of

stores insecure JWT. It is generally believed that the frequency of token leaks and password resets is relatively low. The percentage of JWT that needs to be revoked is small for the entire active user. also JWT only stores an expiration period in the blacklist, which is then deleted, further controlling the blacklist growth. This allows the blacklist to be loaded into the server's memory, helping to complete The local validation of the JWT. You d

the client and server into a "session", thus deriving the "conversational state", which is the concept of sessions. The session describes a communication session mechanism, and a cookie is only a participant in the current mainstream scheme that implements this mechanism, which is typically used to hold session IDs.
