太长加密失败，用encryptlong，npm i encryptlong -s，代码

let encrypt = new JSEncrypt();
encrypt.setPublicKey(`-----BEGIN PUBLIC KEY-----${key}-----END PUBLIC KEY-----`)
var data = encrypt.encryptLong(obj);

encrypt.setPrivateKey(`-----BEGIN PRIVATE KEY-----${key2}-----END PRIVATE KEY-----`)
console.log('解密:', encrypt.decryptLong(data));
