沙箱环境 公钥证书方式 单笔转账 验签出错

按照官方文档使用官方工具生成csr文件，上传到沙箱，生成证书等等...... 在测试pc 支付接口时没问题，出现了待支付界面

但是在测试单笔转账接口时，相应信息错误： ERROR sdk.biz.err - ErrorScene^^40002^^isv.invalid-signature^^null^^Windows 10^^2019-12-05 22:26:06^^ProtocalMustParams:charset=GBK&alipay_root_cert_sn=6bc29aa3b4d406c43483ffea81e08d22&method=alipay.fund.trans.toaccount.transfer&sign=JZAnqNSoP8+amxGe11EoXmY3HdBLg9KJXtA7uTemb2dgaJ0zqqpIxtE4jU8UGNbk2CkQfjheJljeE3lfDv2JjyaLKZ25tktrzCYCqfw3spKNyVokFCBZbhXogggdgXL+EiAvPcJlE/0UI5k6/wGEzW74pCn3vNnKqNaxNKK3ZeNqNXQ7xk8yY0MleVwX+9lDxhQLPD6XVU8vwZUAqVFS1CGwnlR7r0nVsoMtttN4Qpjk5cD9wRYne/pRCG1+gPYH8lmC8MWan2gpbW9MzXMNzoaR1gW1ZyS25dOgCbSgz4SmAgoe0zWXVMUQNFQxx7d9KhfIo/CoecVswicqrnRvIA==&version=1.0&app_id=2016101600696680&sign_type=RSA2&timestamp=2019-12-05 22:26:06^^ProtocalOptParams:alipay_sdk=alipay-sdk-java-4.8.62.ALL&format=json^^ApplicationParams:biz_content={"amount":"0.01","out_biz_no":"120522260615755","payee_account":"acojud6969@sandbox.com","payee_type":"ALIPAY_LOGONID","remark":"test"}^^Body:{"alipay_fund_trans_toaccount_transfer_response":{"code":"40002","msg":"Invalid Arguments","sub_code":"isv.invalid-signature","sub_msg":"验签出错，建议检查签名字符串或签名私钥与应用公钥是否匹配，网关生成的验签字符串为：alipay_root_cert_sn=6bc29aa3b4d406c43483ffea81e08d22&alipay_sdk=alipay-sdk-java-4.8.62.ALL&app_id=2016101600696680&biz_content={"amount":"0.01","out_biz_no":"120522260615755","payee_account":"acojud6969@sandbox.com","payee_type":"ALIPAY_LOGONID","remark":"test"}&charset=GBK&format=json&method=alipay.fund.trans.toaccount.transfer&sign_type=RSA2&timestamp=2019-12-05 22:26:06&version=1.0"},"sign":"ZjL/gkHTaxaJjDyoXm+2cjNM3WZ0IkVpBFabBOwfLF80ZcTXQ5HzJWdpJKWkVT9NysfqBFB3KXGbF6WfDahVMU3PZs0sVHGlYcNlCCneEKEmipcoHeJmmeMuKMG56LF/M0WvMbSbMSPeRz3oUkrkLghT97H07ye//0YufC4YsOX+EdOFnr9e0HUdRUQisu+8SrSWdJBMVKjxauDeB7YoCI9zKDC+A/RK7JDN98O0LLu3vlgLb9xk0TcfmS8woON8oqkWsvJT5dSIWoSHfweu1KnvE369QD0c8YHuDLxI28zQYcihCVAYY2y78cJNYSaitRlY4pCwzMw4mckRsff5Ug=="}^^42ms,177ms,23ms
