尝试汇总时出现"invalid (do_set) left-hand side to assignment“

"invalid (do_set) left-hand side to assignment" 是一个错误信息,通常出现在编程语言中,表示在赋值操作中左侧的表达式无效。

这个错误信息通常是由以下几种情况引起的:

  1. 语法错误:可能是因为在赋值操作中使用了不允许被赋值的表达式,比如常量、函数调用等。在这种情况下,需要检查代码中的赋值语句,确保左侧的表达式是一个合法的可赋值对象。
  2. 变量未声明:如果左侧的表达式是一个未声明的变量,那么就会出现这个错误。在这种情况下,需要确保变量在赋值之前已经声明并初始化。
  3. 只读属性:如果左侧的表达式是一个只读属性,那么就无法对其进行赋值操作。在这种情况下,需要检查代码中的属性访问方式,确保对可写属性进行赋值操作。

总结起来,"invalid (do_set) left-hand side to assignment" 错误信息提示了在赋值操作中左侧的表达式无效。要解决这个错误,需要检查代码中的赋值语句,确保左侧的表达式是一个合法的可赋值对象,并且已经声明并初始化。

  • 密文反馈模式 cfb_密码术中的密文反馈(CFB)

    This is Ciphertext feedback (CFB) which is also a mode of operation for a block cipher. In contrast to the cipher block chaining(CBC) mode, which encrypts a set number of bits of plaintext or original text at a time, it is at times desirable or sensible to encrypt and transfer or exchange some plaintext or original text values instantly one at a time, for which ciphertext feedback is a method in cryptography. Like cipher block chaining(cbc), ciphertext feedback(cfb) also makes use of an initialization vector (IV) in the blocks. CFB uses a block cipher as a component of a different or random number generator in this. CFB mode, the previous ciphertext block is encrypted and the output is XORed (see XOR) with the current plaintext or original text block to create the current ciphertext block from this. The XOR operation conceals plaintext or original text patterns. Original text or plaintext cannot be directly worked on unless there is the retrieval of blocks from either the beginning or end of the ciphertext in the cryptography.
