Python检测URL状态，并追加保存200的URL：

1.Requests

#! /usr/bin/env python#coding=utf-8import sysimport requestsdef getHttpStatusCode(url):    try:        request = requests.get(url)        httpStatusCode = request.status_code        return httpStatusCode    except requests.exceptions.HTTPError as e:        return eif __name__ == "__main__":    with open('1.txt', 'r') as f:        for line in f:            try:                status = getHttpStatusCode(line.strip('\n'))#换行符                if status == 200:                    with open('200.txt','a') as f:                        f.write(line + '\n')                        print line                else:                    print 'no 200 code'            except Exception as e:                print e

2.Urllib

#! /usr/bin/env python#coding:utf-8import os,urllib,linecacheimport sysresult = list()for x in linecache.updatecache(r'1.txt'):    try:       a = urllib.urlopen(x.replace('/n','')).getcode()       #print x,a    except Exception,e:        print e    if a == 200:        #result.append(x)                             #保存        #result.sort()                                       #排序结果        #open('2.txt', 'w').write('%s' % '\n'.join(result)) #保存入结果文件        with open ('200urllib.txt','a') as f: ## r只读，w可写，a追加            f.write(x + '\n')    else:        print 'error'
