服务器端代码

 

class AppController extends Controller
{
   //定义秘钥常量
   const TOKEN = 'API';
    public function check($t,$r,$s)
    {
        //验证身份
        $timeStamp = $t;
        $randomStr = $r;
        $signature = $s;
        $str = $this ->arithmetic($timeStamp,$randomStr);
        if($str != $signature){
            $data = [
                'status' => 0,
                'msg' => '验证失败非法请求'
            ];
            return json_encode($data);
        }else{
            $data = [
                'status' => 1,
                'msg' => '验证请求成功'
            ];
            return json_encode($data);
        }
    }
    //数字签名
    public function arithmetic($timeStamp,$randomStr){
        $arr['timeStamp'] = $timeStamp;
        $arr['randomStr'] = $randomStr;
        $arr['token'] = self::TOKEN;
        //按照首字母大小写顺序排序
        sort($arr,SORT_STRING);
        //拼接成字符串
        $str = implode($arr);
        //进行加密
        $signature = sha1($str);
        $signature = md5($signature);
        //转换成大写
        $signature = strtoupper($signature);
        return $signature;
    }
    
}

用另外一台客户端服务器测试

class diaoyongController extends Controller
{
	const TOKEN ='API';
    public function index(){
   		$timeStamp = time();
    	$randomStr = rand(11,99);
    	$s = $this->arithmetic($timeStamp,$randomStr);
   		$url="http://xd_lyshop.com/home/app/check/$timeStamp/$randomStr/$s";
   		$data=$this->curl_get_https($url);
   		exit($data);
    }
    	
    //数字签名
    public function arithmetic($timeStamp,$randomStr){
    	
        $arr['timeStamp'] = $timeStamp;
        $arr['randomStr'] = $randomStr;
        $arr['token'] = self::TOKEN;
        //按照首字母大小写顺序排序
        sort($arr,SORT_STRING);
        //拼接成字符串
        $str = implode($arr);
        //进行加密
        $signature = sha1($str);
        $signature = md5($signature);
        //转换成大写
        $signature = strtoupper($signature);
        return $signature;
    }
   public function curl_get_https($url){
    $curl = curl_init(); // 启动一个CURL会话
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HEADER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 跳过证书检查
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);  // 从证书中检查SSL加密算法是否存在
    $tmpInfo = curl_exec($curl);     //返回api的json对象
    //关闭URL请求
    curl_close($curl);
    return $tmpInfo;    //返回json对象
   }
}

返回json格式数据

失败0 ，成功1

如：

{"status":0,"msg":"\u9a8c\u8bc1\u5931\u8d25\u975e\u6cd5\u8bf7\u6c42"} 

本例子代码非完整，缺少开发环境，代码功能是完整的，可以参考
