比如内容是
*********.php?haode=yes********789**********
*********.php?haode=yes********246**********
*********.php?haode=yes********221**********
*********.php?haode=yes********687**********
*********.php?haode=yes********215**********
需要替换成
*********.php?type=789********789**********
*********.php?type=246********246**********
*********.php?type=221********221**********
*********.php?type=687********687**********
*********.php?type=215********215**********
