I am trying to capture the function redirecttoauth with a regular expression, but it doesn't do what I expect.
我试图用正则表达式捕获函数redirecttoauth，但它不能达到我的预期。
start = 'function redirecttoauth(sessionid'
end = '}'
result = re.search('%s(.*)%s' % (start, end), s).group(1)
print(result)
and tried to escape } and ) but it didn't work.

regex is really the wrong way to do that. for a simple example your approach might work, you need the DOTALL flag though and you need to escape the parantheses:
正则表达式真是错误的做法。举一个简单的例子你的方法可能有效，你需要DOTALL标志，你需要逃避这些问题：
import re
s = r'''<html>
<head>
<script type="text/javascript">
function redirecttoauth(sessionid, test) {
function body ...
}
</script>
</head>
<body>
</body>
</html>
'''
start = r'function redirecttoauth\(sessionid'
end = r'}'
result = re.search(r'%s(.*)%s' % (start, end), s, re.DOTALL).group(1)
print(result)
