调用付款到银行卡API接口，一直报“签名出错，请根据签名算法进行签名”错误？When calling the payment to bank card API interface, the error "Signature error, please sign according to the signature algorithm" is reported all the time?

编程语言：JAVA

问题描述：我在请求付款至银行卡之前。我先请求了获取公钥并成功，说明我的签名实现代码没错，但是还是提示签名出错。

我初步判断可能出现的问题：（1）公钥有误（但是我的公钥已经转成PKCS#8格式）（2）RSA加密出错。

但是具体问题还是解决不了，请求大佬们帮助，谢谢！

Programming language: Java Problem Description: before I request payment to the bank card. I first requested to obtain the public key and succeeded, indicating that my signature implementation code is correct, but still prompted that the signature is wrong. I preliminarily judge the possible problems: (1) the public key is wrong (but my public key has been converted to pkcs#8 format) (2) RSA encryption is wrong. But the specific problems can't be solved. Please ask the bosses for help. Thank you!

终于找到问题所在！原因找到：desc是中文，可能呢导致了最后sign加密的时候时候出现问题。把desc改成英文的就成功！

Memory:

如果是加密的问题，报错不是签名错误，可以参考https://developers.weixin.qq.com/community/develop/article/doc/00042cea7e8a40fe0b0c0e8f55b813

小炮:好的，感谢
