1. 生成一个随机数：rand_num = 98402563 2. 将50dh和rand_num连接起来：concat_data = "50dh98402563" 3. 将concat_data转换成UTF-8编码的字节序列：byte_data = concat_data.encode('utf-8') 4. 使用SHA-256算法生成摘要：import hashlib hash_object = hashlib.sha256(byte_data) digest = hash_object.hexdigest() 5. 最终的摘要为：e28f1aa547db70c378f3da98a3bda48a70fa2322b87b62f09f99aef2c47f8b59
