PHP開發api介面安全驗證
阿新 • • 發佈：2020-06-01
前臺
這裡我並沒有實際的前臺，直接使用一個PHP檔案代替前臺，然後通過CURL模擬GET請求。
用的是TP框架，URL格式是pathinfo格式。

伺服器端
接受前臺資料進行驗證

namespace Server\Controller;

const TOKEN = ‘API‘;
//響應前臺的請求

exit;

//模擬資料
$arr[‘name‘] = ‘api‘;
$arr[‘age‘] = 15;
$arr[‘address‘] = ‘zz‘;
$arr[‘ip‘] = "192.168.0.1";
echo json_encode($arr);
}
/**

public function arithmetic($timeStamp,$randomStr){
$arr[‘timeStamp‘] = $timeStamp;
$arr[‘randomStr‘] = $randomStr;
$arr[‘token‘] = self::TOKEN;
//按照首字母大小寫順序排序

}
}
結果
string(57) "{"name":"api","age":15,"address":"zz","ip":"192.168.0.1"}"
