wx.requestCommonPayment

报错:fail invalid signature 702002(env: Windows,mp,1.06.2409140; lib: 3.6.5);根据官方的"参考的python脚本"给的示例数据,得到的签名数据没有问题;使用自己的sessionKey,以及appKey出现上面的报错,uri参数值为requestCommonPayment;

经检查,sessionKey未过期,因为签名前调用了checksession接口验证sessionKey有效;appKey也与env=0(正式环境对应);

唯一不确定的是uri参数,官方文档没找到wx.requestCommonPayment对应的uri是什么,只是看有人回复说是"requestCommonPayment",

想问下问题出在哪里?
