The words in Windows core programming cannot dispel doubts. Let's explain it to us in msdn. If you want to give a detailed introduction, go to msdn and take a closer look. I just want to describe it in a language that is easy to understand. Windows ACM and access control mode are composed of two parts. One is access tokens, and the other is Security Identifiers ). An access token is the information used by the process to access the data that indicat

Label:Recently, when a colleague calls the Open API with an iOS app, the server responds with a "invalid_grant" error when it refreshes the access token with refresh token after the access token expires, while in Access If token does not expire, you can refresh access token normally. Take a look at the "refreshing an Expired Access Token" flowchart in the OAuth specification to confirm that there is a problem with the client's operational process. The problem occurs in the (G) procedure. The IO

In the for command statement parameter F, the most difficult to understand is the delims and tokens options. This article makes a simple comparison and summary. "For/F" is often used to parse text and read strings. In terms of division of labor, delims is responsible for splitting strings, while tokens is responsible for extracting strings. If the string is used as a cake, delims is like a knife, used to cu

Token, 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 token to achieve. When the client requ

, The next time the user sends a request to the server, it can take this cookie so that the server verifies the information in the cookie to see if it can find the corresponding record on the server, and if so, indicates that the user has passed the authentication and returns the user's requested data to the client.This is the session, we need to store the server as a login user generated session, these sessions may be stored in memory, disk, or database . We may need to periodically clean out t
