我这边已经拿到了prepay_id数据，但是前端调用wx.requestpayment接口时候，返回支付验证签名失败
在小程序插件支付的时候拉起支付收银台提示"支付验证签名失败"？在小程序中调用插件进行支付，在下单的时候将调用者小程序的appid传送到报文的sub_appid参数中去，系统成功返回了prepay_id等参数。但在小程序拉起支付的时候报错"支付验证签名失败"[图片]，但是如果传宿主小程序appid或者不传到这个参数的时候，就不会出现拉起支付失败的情况； 请求报文如下 <xml> <appid> <![CDATA[wx720c7972a8ca3daf]]> </appid> <area_info> <![CDATA[440112]]> </area_info> <body> <![CDATA[阿强家酸菜鱼（百福广场店）]]> </body> <business> <![CDATA[758]]> </business> <cert_id> <![CDATA[4563293974]]> </cert_id> <channel_id> <![CDATA[218587937]]> </channel_id> <channel_name> <![CDATA[汇聚支付]]> </channel_name> <mch_id> <![CDATA[1505695561]]> </mch_id> <merchant_name> <![CDATA[广州市启正佳元科技有限公司]]> </merchant_name> <nonce_str> <![CDATA[jPh9Lqf3DNR1zQpo]]> </nonce_str> <notify_url> <![CDATA[http://xxx.xxx.xx:8090/netPay_channel_WEIXIN_TRADE_UNION.action]]> </notify_url> <openid> <![CDATA[ovaiX4jfhvMM35ddRCt22SgqivuQ]]> </openid> <out_trade_no> <![CDATA[100223103031687039]]> </out_trade_no> <sign> <![CDATA[X9DIGt49F5lNC8YIJCkVLkWI2EXlZWASRSkhVwRNA25lFudux4+MOQ0/UG87IVG5w9Kg0zTqt9WTuLEDfl36cw==]]> </sign> <sign_type> <![CDATA[SM2]]> </sign_type> <spbill_create_ip> <![CDATA[10.40.50.58]]> </spbill_create_ip> <sub_appid> <![CDATA[wx51d16cc6116c0c4e]]> </sub_appid> <sub_mch_id> <![CDATA[589634745]]> </sub_mch_id> <time_start> <![CDATA[20231030140749]]> </time_start> <total_fee> <![CDATA[3]]> </total_fee> <trade_type> <![CDATA[JSAPI]]> </trade_type> </xml> 返回报文： "bankResult":{ "appid":"wx720c7972a8ca3daf", "cert_id":"4233741533", "mch_id":"1505695561", "nonce_str":"aa30b0d2c78a4c79968c67b55a79ef60", "prepay_id":"wx3014074964554972a2aef90dd0befc0000", "result_code":"SUCCESS", "return_code":"SUCCESS", "return_msg":"成功", "sign_type":"SM2", "sub_appid":"wx51d16cc6116c0c4e", "sub_mch_id":"589634745", "trade_type":"JSAPI", "wc_pay_data":"{\"appId\":\"wx51d16cc6116c0c4e\",\"timeStamp\":\"1698646069\",\"nonceStr\":\"77b32ae4c55b469ca6e0531afe465998\",\"package\":\"prepay_id=wx3014074964554972a2aef90dd0befc0000\",\"signType\":\"RSA\",\"paySign\":\"vypka3ww9mgwdcId4FI4RbkxHn+EXUmASYBMYA04yT2/+fOSM0pANvJPWFl8MOBr0yXcQgTmUNzECxQoIoyynXCyrJ0luB2r6Egd1aT24OqFQ2ppZH8z75neipGIYc5cvbAUJGFJoHWEIwfMJpesAVBLQnQxtorITlV8l3kmf9vByQOXYVbP15/cRYbXLSw2ZI2UYyAaXNF2UySR3db8mbGfzUXYRzi/BuYGgWKEpcOaZlEtFe6sCMolPl2T2DFoPhNza0RYg+cofmx6jWHIWMvANUMFBvLHVBhN1fDx5zmFNkyBA7niOI3y2YvUuRpD2IXGcc9kQ/+xYrJNSCMzfw==\"}" }, "method":"json", "paramMap":{ "result":"{\"appId\":\"wx51d16cc6116c0c4e\",\"timeStamp\":\"1698646069\",\"nonceStr\":\"77b32ae4c55b469ca6e0531afe465998\",\"package\":\"prepay_id=wx3014074964554972a2aef90dd0befc0000\",\"signType\":\"RSA\",\"paySign\":\"KEpcOaZlEtFe6sCMolPl2T2DFoPhNza0RYg+cofmx6jWHIWMvANUMFBvLHVBhN1fDx5zmFNkyBA7niOI3y2YvUuRpD2IXGcc9kQ/+xYrJNSCMzfw==\"}" }, "paySign":"GZH", "status":102 }
