[PHP知识库]JAVA（hmac-sha1）写法用PHP实现

		//Signature = URLEncode(base64(hmac-sha1(AccessKeySecret, urlParam))) ; JAVA写法

        $AccessKeyId = '8882605bd86b1b78956s748256a40261';
        $AccessKeySecret = '5C8gf3tbBH4176jQ9919';
        $method = 'GET';
        $host = 'api-bj.clink.cn/list_clients?';
        $Expires = '6000';
        $Timestamp = urlencode(date('Y-m-d').'T'.date('H:m:s').'Z');
        $urlParam = $method.$host.'AccessKeyId='.$AccessKeyId.'&Expires='.$Expires.'&Timestamp='.$Timestamp;
        
        //$urlParam 这个参数是你需要加密的参数，根据自己的需要去拼接
        var_dump($urlParam);
        
        //下面这一行就是用PHP实现第一行的JAVA写法
        $signature = urlencode(base64_encode(hash_hmac("sha1", $urlParam, $AccessKeySecret, true)));
        var_dump($signature, $urlParam.'&Signature='.$signature);die;
