PHP implements Token instance method-PHP Tutorial-php.cn

This article mainly shares with you the example methods of implementing Token in PHP, hoping to help everyone.

public function set_token($user_name){ $information ['state'] = false; $time = time(); $header = array( 'typ' => 'JWT' ); $array = array( 'iss' => 'auth', // 权限验证作者 'iat' => $time, // 时间戳 'exp' => 3600, // token有效期，1小时 'sub' => 'demo', // 案例 'user_name' => $user_name ) // 用户名 ; $str = base64_encode(json_encode($header)) . '.' . base64_encode(json_encode($array)); // 数组转成字符 $str = urlencode($str); // 通过url转码 $information ['token'] = $str; $this->save_token($user_name, $information ['token']); // 将用户token存放进用户数据库 $information ['username'] = $user_name; // 返回用户名 $information ['state'] = true; return $information; }

Copy after login

Notes:
1. Function save_token(), saves the user's current token in the user table for verification
2. Base64_encode and base64_decode encryption and decryption functions
(1 ) Encryption:

$str='m.sbmmt.com'; //定义字符串 echo base64_encode($str); // 输出编码后的内容为： d3d3LmpiNTEubmV0IOiEmuacrOS5i+Wutg==

Copy after login

(2) Decryption:

$str='d3d3LmpiNTEubmV0IOiEmuacrOS5i+Wutg=='; //定义字符串 echo base64_decode($str); //输出解码后的内容

Copy after login

3. Arrays and objects, convert json format, and reverse
(1) json_encode() is used to convert arrays and objects , converted to json format:

$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);　　 echo json_encode($arr);　 结果为： {"a":1,"b":2,"c":3,"d":4,"e":5}

Copy after login

(2)json_decode() is used to convert json text into the corresponding PHP data structure:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}'; var_dump(json_decode($json)); 结果就是生成一个PHP对象： object(stdClass)#1 (5) {　　　　 ["a"] => int(1)　　　　 ["b"] => int(2)　　　　 ["c"] => int(3)　　　　 ["d"] => int(4)　　　　 ["e"] => int(5)　　 }

Copy after login

4. Chinese processing

echo urlencode("中文-_. ")."\n"; //%D6%D0%CE%C4-_.+ //将中文文字转换成urlencode文字编码 echo urldecode("%D6%D0%CE%C4-_. ")."\n"; //中文-_. //将urlencode文字编码转换成中文文字

Copy after login

public function set_token($user_name){ $information ['state'] = false; $time = time(); $header = array( 'typ' => 'JWT' ); $array = array( 'iss' => 'auth', // 权限验证作者 'iat' => $time, // 时间戳 'exp' => 3600, // token有效期，1小时 'sub' => 'demo', // 案例 'user_name' => $user_name ) // 用户名 ; $str = base64_encode(json_encode($header)) . '.' . base64_encode(json_encode($array)); // 数组转成字符 $str = urlencode($str); // 通过url转码 $information ['token'] = $str; $this->save_token($user_name, $information ['token']); // 将用户token存放进用户数据库 $information ['username'] = $user_name; // 返回用户名 $information ['state'] = true; return $information; }
