各语言普通公钥方式sdk内签名生成sign值及各语言回调数据验签示例代码.

开放平台SDK封装了同步返回响应参数的验签方法，只需在创建DefaultAlipayClient对象进行初始化，设置请求网关(gateway)，应用id(app_id)，应用私钥(private_key)，编码格式(charset)，支付宝公钥(alipay_public_key)，签名类型(sign_type)即可，同步返回响应参数报文时会自动进行验签。

注：本文示例代码仅供测试参考 java语言：签名方法：

//请求的待签名字符串（已升序排序处理） String content = "app_id=201****222&biz_content={"out_trade_no":"20190401144352106451724","total_amount":"0.01","subject":"土豪机","timeout_express":"10m","qr_code_timeout_express":"2m","store_id":"HK001"}&charset=UTF-8&format=json&method=alipay.trade.precreate&notify_url=http://notify.dengw.online/do/6e5e3bd0-c2c5-4565-bcfd-bf57ea822672&sign_type=RSA2&timestamp=2019-04-01 14:43:53&version=1.0"; //私钥 String privateKey=""; //编码格式 String charset="utf-8"; //签名方式 String sign_type="RSA2";
