ISVAliPay获取api_alipay_open_auth_token_app一直提示验签错误

[LiamChan]

ISVAliPay获取api_alipay_open_auth_token_app一直提示验签错误，'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，

我把私钥和公钥证书全部都重新申请了一次还是不行。也不知道是哪里出了什么问题。

抱歉， 最近比较忙没有时间回复。

在支付宝开放平台的沙箱环境申请应用。 在各项信息配置好之后， 访问如下链接

https://openauth.alipaydev.com/oauth2/appToAppAuth.htm?app_id={你的APPID}&redirect_uri=http%3A%2F%2F127.0.0.1

然后使用买家信息登录并授权。可以获取app_auth_code

然后使用如下示例的代码， 可以获取到app_auth_token

from datetime import datetime

from alipay import AliPay, ISVAliPay

private_key_string = open("certs/app_private_key.pem").read()
public_key_string = open("certs/ali_public_key.pem").read()
isv = ISVAliPay(
    appid="你的appid",
    app_notify_url="http://114.229.67.15:8088/billalipay",
    app_private_key_string=private_key_string,
    alipay_public_key_string=public_key_string,
    sign_type="RSA2",  # RSA or  RSA2
    debug=True,
    app_auth_code="你的code"
)


response = isv.api_alipay_open_auth_token_app()
print(response)

可以获取如下响应：

{
  "code": "10000",
  "msg": "Success",
  "app_auth_token": "202010BB4436ccd26f6345d0b66260f3adc6eX69",

你可以先测试一下

麻烦你了，十分感谢。但是我通过支付宝证书方式还是有问题，我换成了密钥的方式就可以了。
