. When these 9 characters are combined, it matches the character string in the same order as the expression and at the same position as the corresponding character (in fact, it is a string exactly the same as the expression ). Because this matching method is the least flexible, it can only match exactly the same characters, so it is also called "full match ".Additional reading The topic list of this article is as follows: What is a regular expression?

"." Can match any single character, English letter, number, and itself. Now we can learn it by combining the full-text match described above:Effect demonstration The regular expression is as follows: ..g Www.bkjia.com Www.google.com Www.abc.org Www.bkjia.com Www.google.com Www.abc.org As you can see, for the expression "www.bkjia.com", the "bkjia" section is a full-text match, and can only be fixed to match the "bkjia" string; ". ", can match any single character (including the character". ).
Greedy) It will match as many characters as possible. It first looks at the entire string. If it does not match, the string is reduced. If it encounters a possible match, it stops shrinking and expands the text. When a matching text is found, it does not rush to save the match to the matching set, but expands the text until it cannot continue matching or expand the complete string, save the last matched text (also the longest) to the matching set. So it is greedy. Looking at the above definition

From a practical standpoint, the response object (obtained from the server's callback function ONrequest ()) is passed to the request handler by a request route. The handler can then take a function on the object to respond to the request. This is how it works, and then let's move on to it in a step-by-step
