python - 如何确保输入键没有被输入密码

Question

我遇到以下问题，当 python 脚本运行时，用户在命令窗口中不断按下“enter 键”...以下是在命令窗口中运行的内容，但用户不断按下 enter，最终被送入密码和脚本失败，我该如何防止这种情况发生？

 Parsing the XML

 Building the build combo table

  **Password: //asks for password but user had multiple enter key presses above which is taken as passoword and fails**

Python 代码:-

url='http://wiki.com/'+wikiName+'/w/index.php?title='+hId +'_'+rId+'&action=edit'
cookiehand = urllib2.HTTPCookieProcessor()
password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
password_mgr.add_password(user=getpass.getuser(),passwd=getpass.getpass(),uri=authhost,realm=realm)
auth_handler = urllib2.HTTPBasicAuthHandler(password_mgr)
opener = urllib2.build_opener(auth_handler, cookiehand)
urllib2.install_opener(opener)
# make the request
req = urllib2.Request(url=url)
try:
    f = urllib2.urlopen(req)
    txt = f.read()
    f.close()
except urllib2.HTTPError, e:
    txt = ''
    print 'An error occured connecting to the wiki. No wiki page will be generated.'//eventually gets this error

我认为您应该在读取密码之前尝试刷新用户输入。
