HttpRequestBase類別 屬性演示

 

先準備範例，程式碼很長，甚入

前端 index.cshtml

@{
    ViewBag.Title = "Index";

    var result = (Dictionary<string, string>)Model;
    var browser = (Dictionary<string, string>)ViewBag.browser;

}
<h2>@ViewBag.Title.</h2>

<table style="border: 1px solid;">

    <tr>
        <th>Request attributes</th>
        <th>值</th>
    </tr>

    @{
        foreach (var item in result)

            </tr>
        }
    }

<p></p>
<table style="border: 1px solid;">

    <tr>
        <th>Request.Params attributes</th>
        <th>值</th>
    </tr>

            </tr>
        }
    }
</table>
<p></p>
<table style="border: 1px solid;">

    <tr>
        <th>Request.serverVariables attributes</th>
        <th>值</th>
    </tr>

    @{

HttpRequestBase 類別 (就是Controller底下的Request屬性) 可以用來

1、取使用者IP (UserHostAddress)

2、判斷使用者的作業系統、瀏灠器版本為何 (UserAgent)

3、判斷使用者是否使用手持裝置 (IsMobileDevice)

4、是否開啟或支援java、JavaScript (Request.Browser.JavaApplets)

5、取得cookies、QueryString、header等資訊

 

HttpRequestBase 類別的屬性很多，但並不是所有資訊都正確，僅供參考。
