回调验证签名

from alipay.aop.api.util.SignatureUtils import verify_with_rsa# 支付宝公钥
alipay_public_key = '你的支付公钥'# 待签名字符串需要做升序处理,且去除sign和sign_type
org_message = '返回的body'# 转换成字节串
message = bytes(org_message, encoding='utf-8')# 返回的sign值（需要base64解码，python中sign解码封装在了verify_with_rsa方法中）
sign = 'body中截取的sign'# 签名方法
data= verify_with_rsa(alipay_public_key, message, sign)# 输出验签结果
print(data)try:# 处理支付成功的逻辑if data.get('trade_status') == 'TRADE_SUCCESS':order_no = data.get('out_trade_no')# 查询订单 对订单进行更新等操作return JSONResponse(status_code=200,content={'code': 1, 'msg': '支付成功'})# 处理支付失败的逻辑elif data.get('trade_status') in ['TRADE_CLOSED', 'TRADE_FINISHED']:order_no = data.get('out_trade_no')# 支付失败的对订单更新操作return JSONResponse(status_code=200,content={'code': 1, 'msg': '支付失败'})
