&[0-9a-zA-Z]+=[0-9a-zA-Z]+&

您可能需要根据要允许的字符更改[0-9a-zA-Z]。

& matches the characters & literally
[0-9a-zA-Z]+ match a single character present in the list below
    Quantifier: + Between one and unlimited times, as many times as possible, giving back as needed [greedy]
    0-9 a single character in the range between 0 and 9
    a-z a single character in the range between a and z (case sensitive)
    A-Z a single character in the range between A and Z (case sensitive)
= matches the character = literally
