python之用于匹配 URL 中电子邮件的正则表达式

我的 Django 代码中有一个正则表达式，但我不知道它的实际含义。这是我的正则表达式:

r'^email/(?P<email>[^@\s]+@[^@\s]+\.[^@\s]+)/$', 

你能给我一些匹配这个正则表达式的例子吗？

请您参考如下方法:

正则表达式电路

您可以在 jex.im 中可视化您的表情:

您还可以在 regex101.com 中测试/修改/更改您的表达式.

基本上，您的表达式将匹配:

email/some_alphanumeric[A-Z0-9]_special_chars_@#$*some_alphanumeric_special_chars_#$*.some_alphanumeric_special_chars_#$* 

Demo

如果你想匹配:

myurl/email/blabla@blabla.com 

您可以 modify it to :

myurl\/email\/([^@\s]+@[^@\s]+\.[^@\s]+)

import re 
 
regex = r"myurl\/email\/([^@\s]+@[^@\s]+\.[^@\s]+)" 
 
test_str = "myurl/email/blabla@blabla.com" 
 
matches = re.finditer(regex, test_str, re.MULTILINE) 
 
for matchNum, match in enumerate(matches, start=1): 
 
    print ("Match {matchNum} was found at {start}-{end}: {match}".format(matchNum = matchNum, start = match.start(), end = match.end(), match = match.group())) 
 
    for groupNum in range(0, len(match.groups())): 
        groupNum = groupNum + 1 
 
        print ("Group {groupNum} found at {start}-{end}: {group}".format(groupNum = groupNum, start = match.start(groupNum), end = match.end(groupNum), group = match.group(groupNum))) 
 
# Note: for Python 2.7 compatibility, use ur"" to prefix the regex and u"" to prefix the test string and substitution.
