我已经尝试使用cipher.getinstance（“rsa/ecb/pkcs1padding”），但没有给出预期的结果。

感谢所有的帮助。祝你有美好的一天。

停止了一段时间的工作。回到这里，发现我犯了一个非常愚蠢的错误。加密是对的。当我将password作为查询参数传递时，我需要用url编码替换'='、'+'和'/'。参考：w3schools.com/tags/ref_urlencode.asp。

下面是我添加的最后代码：

String urlSafePassword = Base64.getEncoder().encodeToString(encryptedPassWord);
            urlSafePassword.replace("/", "%2F");
            urlSafePassword.replace("+", "%2B");
            urlSafePassword.replace("=", "%3D");
            return urlSafePassword;

我一直在想我的内疚类型。
