使用

//生成签名$request = [                'a' => 1,                'b' => 2,                'c' => 3,                'sign_type' => 'HMAC-SHA256',                'timestamp' => time() + 600,                'nonce_str' => SignatureService::createNonceStr(),        ];            SignatureService::init($request);            $result = SignatureService::validateQueryParam();            if (!$result['status']) exit($result['message']);            $key = 'helloworld';            $signature = SignatureService::createSignatureString(SignatureService::createSortQueryString($request), $request['sign_type'], $key);            $request['key'] = $key;            $request['signature'] = $signature;            echo "";            print_r($request);            //校验签名            $validate = SignatureService::validateRequest($request, false);
必要参数：
'sign_type' => 'HMAC-SHA256', //签名类型，当前支持SHA256、MD5
'timestamp' => '1539255134', //时间戳
'nonce_str' => 'n5ryqp0f9ur3u3u8lxfblxw9h03emyka',//随机数
'key' => 'helloworld', //密钥
'signature' => 'f0ca487612f15059c47aba5e8503c6400981fbed20d1af958003e3f798d1bbd2',//签名
