Transfer from simple book Http://www.jianshu.com/p/576dbf44b2aeWhat is Jwtjson Web token (JWT) is a JSON-based open standard (RFC 7519) that executes in order to pass claims across a network application environment. The token is designed to be compact and secure, especially for single sign-on (SSO) scenarios in distributed sites. JWT declarations are typically used to pass authenticated user identities betw

----- Another way to clone accounts Author: aXis) Source: www.3389.net Abstract: About the acl, token, and privilege of nt, and bypassing the acl through privilege, the object access is achieved. It can be said that it is another way to clone the administrator, but it is more concealed and difficult to use. It is necessary to bypass the detection. Currently, the breakthrough is to bypass the acl using permissions. Keywords: ACL, ACE, DACL,

Generate a short token string Sometimes, we need to generate some tokens as the identifiers, such as the authenticated identifiers and resource extraction codes. A common algorithm is to generate a guid as the token. Because of its randomness and uniqueness, token is a very reliable choice. GUID is an array of bits. To facilitate portability, it is often expresse

Ii. Token problems and Usage DetailsWhat is a Token? Token can be understood as a Token. The server verifies the Token to determine whether you have the permission for this operation. An important feature of Token is validity. Ge

I searched the internet and many webmasters said this.1. Set the submit button to disabled.After the user submits the request, immediately change the button to unavailable. This is implemented using js.The code before submission is as follows: The code is as follows:Copy code $ ("# Submit"). attr ('disabled ', 'true ');$ ("# Submit"). val ("submitting, please wait "); After execution, set the button to the original stateThe code is as follows:

;$numChars = count ($chars)-1;$token = ';# Create Random token at the specified lengthfor ($i = 0; $i $token. = $chars [Mt_rand (0, $numChars)];# Should token be run through MD5?if ($MD 5) {# Number of char chunks$chunks = Ceil (strlen ($token)/32);$MD 5token = ';# Run each

Sometimes some of the improperly processed SH script files in Windows are placed under Linux to perform an error, prompting for a newline character, mainly because the end of the EOL line under window is "\ r \ n" two characters, while Linux,unix is "\ n".The following VIM commands are confirmed.: E ++ff=unix% #显示回车符 (\ r), specific in the VIM environment will be displayed as "^m" symbol: Set list #显示换行符 (\ n), the specific re-vim environment appears as "$" symbol. This command also displays tab

If you are 360 fast browser (360 browser not tested), please open it carefully: Load failure will cause crash, computer CPU will run crazy (CPU fan suddenly become faster), and finally cause the browser to crash2, if you are IE browser (beta version is IE11), can be unscrupulous3, if you are Google Chrome,

In Seasonenum.javapublic class Seasonenum {public enum Features {}}If the appeal code is an error: enum cannot is resolved to a type, which indicates that the system does not recognize an enum. j2se1.5 added the enum keyword to define the enumeration class. Therefore, the enum can only be used after jdk1.5 and later.Workaround:Open the project corresponding to the Properties-->java Compiler, modify the Compiler compliance level to 1.5 or more than 1.5.Syntax error on

The reason for this is definitely a problem with the JSON format returned Most likely is the background in the program execution process, output some debugging information, and so on, these output strings and JSON stitching into a new string to parse, this will be an error; For example, I var_dump in the import file __dir__, when the request JSON return normal data, but in the Josn.pares () error, delete the var_dump after the normal execution. JS parsing json times: unexpected

The most likely cause of this problem is:Files written under Windows are uploaded to Linux execution.I wrote the code on notepad++, and then uploaded it to Linux to execute it and report this error. Careful examination, there is no grammatical error. Surfing the Internet, found that Windows and Linux are different lines of the cause of the change.Windows is carriage return + line Crlf;linux is just a line break LFCr means carriage return, enter, \R,ASCII code of 13LF means linefeed, newline, \n,

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 typically used in two places- preventing forms from repeating commits, anti CSRF attacks (cross-site request forgery). Both are based on the principle of the session token to achiev
