使用异常进行 md5 搜索

发布于 2024-10-31 08:52:25 字数 446 浏览 2 评论 0原文

import httplib
import re 

md5 = raw_input('Enter MD5: ') 

conn = httplib.HTTPConnection("www.md5.rednoize.com")
conn.request("GET", "?q="+ md5) 
try:
     response = conn.getresponse()
     data = response.read() 
     result = re.findall('<div id="result" >(.+?)</div', data)
     print result
except:
     print "couldnt find the hash"

raw_input()

我知道我可能执行了错误的代码，但是我应该使用哪个异常？如果找不到哈希，则引发异常并打印“无法找到哈希”

原文

import httplib
import re 

md5 = raw_input('Enter MD5: ') 

conn = httplib.HTTPConnection("www.md5.rednoize.com")
conn.request("GET", "?q="+ md5) 
try:
     response = conn.getresponse()
     data = response.read() 
     result = re.findall('<div id="result" >(.+?)</div', data)
     print result
except:
     print "couldnt find the hash"

raw_input()

I know I'm probably implementing the code wrong, but which exception should I use for this? if it cant find the hash then raise an exception and print "couldnt find the hash"

由于 re.findall 不会引发异常，因此这可能不是您想要检查结果的方式。相反，你可以写类似的东西

result = re.findall('<div id="result" >(.+?)</div', data)
if result:
    print result
else:
    print 'Could not find the hash'

Since re.findall doesn't raise exceptions, that's probably not how you want to check for results. Instead, you could write something like

result = re.findall('<div id="result" >(.+?)</div', data)
if result:
    print result
else:
    print 'Could not find the hash'

如果你真的想有一个例外，你必须定义它：

class MyError(Exception):
   def init(self, value):
       self.value = value
   def str(self):
       return repr(self.value)

 <代码>尝试：
    响应 = conn.getresponse()
    数据 = 响应.read() 
    结果 = re.findall('(.+?)

If you realy like to have an exception there you have to define it:

class MyError(Exception):
   def init(self, value):
       self.value = value
   def str(self):
       return repr(self.value)

try:
    response = conn.getresponse()
    data = response.read() 
    result = re.findall('(.+?)</div', data)
    if not result:
        raise MyError("Could not find the hash")
except MyError:
   raise
