Example method for implementing token in PHP

This article is mainly to share with you the PHP implementation token of the example method hope to help everyone.

Public Function Set_token ($user _name) {    $information [' state '] = false;    $time = time ();    $header = Array (        ' typ ' = ' JWT '    );    $array = Array (        ' iss ' = ' auth ',//rights verification author        ' Iat ' = $time,//timestamp        ' exp ' = ' = ',//token validity, 1 hours        ' Sub ' = ' demo ',//Case        ' user_name ' + $user _name    )//user name    ;    $str = Base64_encode (Json_encode ($header)). '.' . Base64_encode (Json_encode ($array)); The array is converted into characters    $str = UrlEncode ($STR);//transcoding via URL    $information [' token '] = $STR;    $this->save_token ($user _name, $information [' token ']); The user token is stored in the user database    $information [' username '] = $user _name;//Returns the user name    $information [' state '] = true;    return $information;}

Annotations:
1, Function Save_token (), the user's current token is saved in the user table, for verifying
2, Base64_encode and Base64_decode cryptographic decryption function
(1) Encryption:

$str = ' www.php.cn '; Defines the string echo base64_encode ($STR);  The output code is as follows: d3d3lmpinteubmv0ioiemuacros5i+wutg==

(2) Decryption:

$str = ' d3d3lmpinteubmv0ioiemuacros5i+wutg== ';     Defines the string echo base64_decode ($STR); Output decoded content

3. Arrays and objects, convert JSON format, and invert
(1) Json_encode () is used to convert arrays and objects into JSON format:

$arr = Array (' A ' =>1, ' B ' =>2, ' C ' =>3, ' d ' =>4, ' e ' =>5);　echo Json_encode ($arr); The result is: {"A": 1, "B": 2, "C": 3, "D": 4, "E": 5}

(2) Json_decode () is used to convert JSON text to the appropriate PHP data structure:

$json = ' {' A ': 1, ' B ': 2, ' C ': 3, ' d ': 4, ' E ': 5} '; Var_dump (Json_decode ($json)); The result is a PHP object: Object (StdClass) #1 (5) {["a"] = = Int (1) ["B"] + int (2) ["C"] + int (3) ["D"] + int (4) ["e"] = = Int (5)}

4. Chinese processing

Echo UrlEncode ("Chinese-_."). " \ n "; %d6%d0%ce%c4-_.+      //convert Chinese text to urlencode text encoding echo urldecode ("%d6%d0%ce%c4-_."). " \ n "; Chinese-_.       Convert urlencode text encoding to Chinese text

Public Function Set_token ($user _name) {    $information [' state '] = false;        $time = time ();        $header = Array (        ' typ ' = ' JWT '    );    $array = Array (        ' iss ' = ' auth ',//rights verification author        ' Iat ' = $time,//timestamp        ' exp ' = ' = ',//token validity, 1 hours        ' Sub ' = ' demo ',//Case        ' user_name ' + $user _name    )//user name    ;        $str = Base64_encode (Json_encode ($header)). '.' . Base64_encode (Json_encode ($array)); The array is converted into characters    $str = UrlEncode ($STR);//transcoding via URL    $information [' token '] = $STR;        $this->save_token ($user _name, $information [' token ']); The user token is stored in the user database    $information [' username '] = $user _name;//Returns the user name    $information [' state '] = true;    return $information;}
