    Win10 UWP

    我想得到我CSDN博客的阅读量,那么我应该做一个软件,这个软件可以查看当前的 csdn 博客访问量

    界面

    启动界面

    启动完成输入需要统计的博客的网址

    代码

    看界面很简单,就一个List做的

    主要技术是爬虫

    我们先做一个TextBox放博客地址

                <TextBox Margin="10,10,10,10" Header="博客地址" PlaceholderText="http://blog.csdn.net/lindexi_gd" Text="{x:Bind view.PostCsdn.Url,Mode=TwoWay}"></TextBox>
    
    

    我们还需要类Post存放我们的博客

        public class Post : NotifyProperty
        {
            public Post()
            {

                }
                get
                {

    获得csdn的访问量积分等,我们需要得到我们现在所在的页,如果我们在第一页就获取,还获取最大页数,如果我们现在不是第一页就不获取

                {
                    var temp = postTitle.First();
                    temp.ClonePost(post);
                }
                else
                {
                    //await Window.Current.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
                    //{
                    //    PostCollection.Add(post);
                    //});
                    await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal,
                        () =>
                        {
                            PostCollection.Add(post);
                        });
                }
            }
    

    现在我使用的方法是 asp dotnet core 通过图片统计 csdn 用户访问

    ListView宽度过小

    这个问题简单。

                    <ListView.ItemContainerStyle>
    
                        <Style TargetType="ListViewItem">
    
                            <Setter Property="HorizontalContentAlignment"
    
                                    Value="Stretch"></Setter>
    
                        </Style>
    
                    </ListView.ItemContainerStyle>

    我们可以使用我们的ListView放数据

    获取博客

    获取博客可以访问网站,获取源码,使用匹配到的数据

    我们写软件,一般是用用一个页面来做导航,这个页面就是一个Frame,然后包含各种导航,所以这个页面会一直存在我们的内存。

    然后我们需要把MainPage一开始就导航到我们这个页面,我们可以拿到我们的Content,然后把Content给一个Frame,用Frame导航。

            public MainPage()
            {
                this.InitializeComponent();
                Frame frame=Content as Frame;
                if (frame == null)
                {
                    frame=new Frame();
                    Content = frame;
                }
                frame.Navigate(typeof(View.AssBjPage));
            }
    

    if (frame == null)一定会true,因为Content 一般是Grid,我们把content改为Frame
