但是如果使用自己生成的 应用公钥 就能成功初始化
py版本使用过 3.9 和3.6都会报错
应该密钥生成使用过 支付宝开发平台开发助手和openssl 结果都是一样的
也看了文档里面提供的证书的格式 但是那里好像只有应用公钥 没有支付宝公钥 所以无法进行对比
我从支付宝沙箱环境下载公钥， 貌似是好的 请问你的支付宝公钥 哪里来的？
是从支付宝获取的
我跟你是从同一个地方复制下来的， 但是内容不同， 估计每个账号的公钥都不一样。 你可以复制粘贴到这边吗。 我现在只能怀疑是你复制粘贴错了

base64的意义在于将3个二进制转化成4个字节的可读自字符。可是你给我的长度是387, 我不知道问题出在哪里， 这个公钥绝对是有问题的
好的 我去问一下支付宝那边的 谢谢大佬解答
问题解决了 是支付宝的问题 让支付宝那边重置一下沙箱账号 然后生成的支付宝公钥就是正常的392位了
这也是活久见了
