win10 应用应该是要有访问网络，网络现在最多的是使用GET，Post，简单的使用，可以用网络的数据：获得博客的访问量。

在使用网络，我们需要设置Package.appxmanifest

网络请求使用GET，首先有要访问的网站
[mw_shl_code=csharp,true]string url = "http://blog.csdn.net/lindexi_gd/article/details/50830924";
//url是我一篇博客，win10 UWP Hmac，我很多博客都是读书笔记[/mw_shl_code]

WebRequest是请求基类，需要使用WebRequest.Create(url);
[mw_shl_code=csharp,true]request.Method = "GET";[/mw_shl_code]


UWP 的Header设置
[mw_shl_code=csharp,true] request.Headers["Cookie"] [/mw_shl_code]


接受需要一个函数 AsyncCallback
[mw_shl_code=csharp,true]private void response_callback(IAsyncResult result)[/mw_shl_code]

[mw_shl_code=csharp,true]request.BeginGetResponse(response_callback, request);[/mw_shl_code]


response_callback接受信息HttpWebRequest http_web_request = (HttpWebRequest)result.AsyncState;
[mw_shl_code=csharp,true]WebResponse web_response = http_web_request.EndGetResponse(result);
using (Stream stream = web_response.GetResponseStream())
{
using (StreamReader reader = new StreamReader(stream))
{
string content = reader.ReadToEnd();
}
}[/mw_shl_code]



我们需要对content进行正则

正则可以看 ***链接停止解析***
[mw_shl_code=csharp,true]Regex regex = new Regex(@"<span class=""link_view"" title=""阅读次数"">(\d\d\d人阅读)</span>");
string str = regex.Match(content).Result("阅读：$1");
reminder(str);[/mw_shl_code]

如果使用UI，直接使用会出现

我们写函数
[mw_shl_code=csharp,true]private async void reminder(string str)
{
await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal,
() =>
{
tb.Text += str;
});
}[/mw_shl_code]


网络很容易就异常
[mw_shl_code=csharp,true]catch (WebException e)
{
switch (e.Status)
{
case WebExceptionStatus.CacheEntryNotFound:
break;
case WebExceptionStatus.ConnectFailure:
reminder("ConnectFailure:远程服务器连接失败");
break;
case WebExceptionStatus.ConnectionClosed:
break;
case WebExceptionStatus.KeepAliveFailure:
break;
case WebExceptionStatus.MessageLengthLimitExceeded:
reminder("MessageLengthLimitExceeded 网络请求消息长度受到限制");
break;
case WebExceptionStatus.NameResolutionFailure:
break;
case WebExceptionStatus.Pending:
reminder("Pending 内部异步挂起");
break;
case WebExceptionStatus.PipelineFailure:
break;
case WebExceptionStatus.ProtocolError:
break;
case WebExceptionStatus.ProxyNameResolutionFailure:
break;
case WebExceptionStatus.ReceiveFailure:
break;
case WebExceptionStatus.RequestCanceled:
break;
case WebExceptionStatus.RequestProhibitedByCachePolicy:
break;
case WebExceptionStatus.RequestProhibitedByProxy:
break;
case WebExceptionStatus.SecureChannelFailure:
break;
case WebExceptionStatus.SendFailure:
break;
case WebExceptionStatus.ServerProtocolViolation:
break;
case WebExceptionStatus.Success:
break;
case WebExceptionStatus.Timeout:
break;
case WebExceptionStatus.TrustFailure:
break;
case WebExceptionStatus.UnknownError:
break;
}
reminder(e.Message);
}[/mw_shl_code]


post需要把request.Method = "POST";

传输在request.BeginGetRequestStream(respeonse_streamCallback, request);
[mw_shl_code=csharp,true]private void respeonse_streamCallback(IAsyncResult result)
{
HttpWebRequest http_web_request = (HttpWebRequest) result.AsyncState;
using (Stream stream=http_web_request.EndGetRequestStream(result))
{
//发送byte
string str = "c";
byte[] buffer = Encoding.UTF8.GetBytes(str);
stream.Write(buffer,0,buffer.Length);
}
http_web_request.BeginGetResponse(response_callback, http_web_request);
}[/mw_shl_code]


简单方法
[mw_shl_code=csharp,true]HttpClient http=new HttpClient();
reminder(await http.GetStringAsync(new Uri(url)));[/mw_shl_code]


获整个对象
[mw_shl_code=csharp,true]HttpResponseMessage response = await http.GetAsync(new Uri(url));
reminder(await response.Content.ReadAsStringAsync());[/mw_shl_code]

[mw_shl_code=csharp,true]HttpClient http = new HttpClient();
HttpStringContent http_string =new HttpStringContent("a");
HttpResponseMessage response = await http.PostAsync(new Uri(url), http_string);
string str = await response.Content.ReadAsStringAsync();
reminder(str);[/mw_shl_code]

[mw_shl_code=csharp,true]HttpClient http = new HttpClient();
InMemoryRandomAccessStream memory =new InMemoryRandomAccessStream();
HttpStreamContent stream=new HttpStreamContent(memory);
HttpResponseMessage response = await http.PostAsync(new Uri(url), stream);
string str = await response.Content.ReadAsStringAsync();
reminder(str);[/mw_shl_code]

[mw_shl_code=csharp,true]HttpClient http = new HttpClient();
InMemoryRandomAccessStream memory = new InMemoryRandomAccessStream();
HttpStreamContent stream = new HttpStreamContent(memory);
HttpRequestMessage request=new HttpRequestMessage(HttpMethod.Post,new Uri(url));
request.Content = stream;
HttpResponseMessage response = await http.SendRequestAsync(request);
string str = await response.Content.ReadAsStringAsync();[/mw_shl_code]

看到有人说CSDN博客访问统计是Cache，如果我们要有很多访问，可以使用
[mw_shl_code=csharp,true]filter.CacheControl.WriteBehavior = HttpCacheWriteBehavior.NoCache;
await Task.Run(() =>
{
reminder("\n");
WebRequest request = WebRequest.Create(url);
request.Method = "GET";
request.Headers["Cookie"] = string.Empty;
request.BeginGetResponse(response_callback, request);
});[/mw_shl_code]

我把之前写的一个刷500

cookie可以使用HttpBaseProtocolFilter

设置cookie
[mw_shl_code=csharp,true]HttpCookie cookie = new HttpCookie("名称", "blog.csdn.net", "/")
{
Value = "a",
};
filter.CookieManager.SetCookie(cookie, false);[/mw_shl_code]
