Interface debugging tool https://pay.weixin.qq.com/wiki/tools/signverify/also tested the second signature Sign is right, don't understand, why always prompt "verify signature failure",

NonceStr numerical is unified to order the returned string,

Key is also no problem, do NATIVE payment is successful,
