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()
{
}
/// <summary>
/// 阅读数
/// </summary>
public string LinkView
{
set
{
_linkView = value;
OnPropertyChanged();
}
get
{
return _linkView;
}
}
public string Original
{
set
{
_original = value;
OnPropertyChanged();
}
get
{
return _original;
}
}
/// <summary>
/// 文章
/// </summary>
public string Title
{
set;
get;
}
/// <summary>
/// 链接
/// </summary>
public string Url
{
set;
get;
}
public string Time
{
set;
get;
}
public DateTime LastTime
{
set;
get;
}
public int AddView
{
set
{
_addView = value;
OnPropertyChanged();
}
get
{
return _addView;
}
}
public List<Scrutiny> ScrutinieCollection
{
set;
get;
}=new List<Scrutiny>();
public void ClonePost(Post post)
{
int postLinkView = int.Parse(post.LinkView);
int linkView = int.Parse(LinkView);
if (postLinkView >= linkView)
{
AddView = postLinkView - linkView;
}
else
{
throw new FormatException();
}
LinkView = post.LinkView;
Time = post.Time;
LastTime = post.LastTime;
ScrutinieCollection.Add(new Scrutiny()
{
LinkView = LinkView,
Time = LastTime
});
}
private int _addView;
private string _linkView;
private string _original;
}
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
private void CompositionOriginal()
{
TotalPost = PostCollection.Count.ToString();
//Original
//var original = PostCollection.Where(temp => temp.Original == "ico ico_type_Original");
var original = PostCollection.Where(temp => temp.Original == "原");
Original = original.Count().ToString();
//Reprint
//var reprint = PostCollection.Where(temp => temp.Original == "ico ico_type_Translated");
var reprint = PostCollection.Where(temp => temp.Original == "转");
Reprint = reprint.Count().ToString();
//Translation
//var translation = PostCollection.Where(temp => temp.Original == "ico ico_type_Repost");
var translation = PostCollection.Where(temp => temp.Original == "翻");
Translation = translation.Count().ToString();

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
