输入127.0.0.1或localhost总是跳转到一个网址导航，怎么办

进入C:\WINDOWS\system32\drivers\etc，右键使用记事本打开hosts，看看127.0.0.1或者localhost是不是被指向了网址导航，如果指向了就把那两行删了

您好，这个是由于系统的hosts被篡改导致的，因为浏览器在浏览网页时会优先使用本地hosts对域名进行解析，所以这个文件一旦出现错误将会导致原网页打开时跳转、不能正常打开等问题。解决方法：将现有hosts文件替换成默认文件即可。hosts文件一般在c:\windows\system32\drivers\etc\目录下。修复方法：只需将hosts文件用记事本打开，将里面的内容全部删除然后替换成 # copyright (c) 1993-2009 microsoft corp. # # this is a sample hosts file used by microsoft tcp/ip for windows. # # this file contains the mappings of ip addresses to host names. each # entry should be kept on an individual line. the ip address should # be placed in the first column followed by the corresponding host name. # the ip address and the host name should be separated by at least one # space. # # additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # for example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 即可。
