asp.net url重寫(xiě)后頁(yè)面回傳問(wèn)題
asp.net url重寫(xiě)后頁(yè)面回傳問(wèn)題:具體辦法如下：可以通過(guò)自定義頁(yè)面基類，重寫(xiě)默認(rèn)的HtmlTextWriter方法，重寫(xiě)屬性輸出WriteAttribute(string name, string value, bool encode)方法，當(dāng)輸出action時(shí)，將action屬性的值強(qiáng)制轉(zhuǎn)換為當(dāng)前虛URL(HttpContext.Current.R

具體辦法如下：可以通過(guò)自定義頁(yè)面基類，重寫(xiě)默認(rèn)的HtmlTextWriter方法，重寫(xiě)屬性輸出WriteAttribute(string name, string value, bool encode)方法，當(dāng)輸出action時(shí)，將action屬性的值強(qiáng)制轉(zhuǎn)換為當(dāng)前虛URL(HttpContext.Current.Request.RawUrl，上面的~/showVisasAll_(\w+)\.aspx)
最后就是讓所有的頁(yè)面都調(diào)用這個(gè)基類，修改一下Web.config就好了
<!-- Openlab.Controls.OLPage為頁(yè)面基類，Openlab.Controls為基類所在dll -->
<pages pageBaseType="Openlab.Controls.OLPage, Openlab.Controls"/>
附頁(yè)面基類完整代碼（參考CS代碼完成）：
代碼如下:

using System.IO;
using System.Web;
using System.Web.UI;
namespace Openlab.Controls
...{
/**//// <summary>

/// </summary>
/// <param name="writer"></param>
protected override void Render(HtmlTextWriter writer)
...{
if (writer is System.Web.UI.Html32TextWriter)
...{
writer = new FormFixerHtml32TextWriter(writer.InnerWriter);
}
else
...{
writer = new FormFixerHtmlTextWriter(writer.InnerWriter);
}
base.Render(writer);
}
#endregion
}
FormFixers#region FormFixers
FormFixerHtml32TextWriter#region FormFixerHtml32TextWriter
internal class FormFixerHtml32TextWriter : System.Web.UI.Html32TextWriter
...{
private string _url; // 假的URL
internal FormFixerHtml32TextWriter(TextWriter writer):base(writer)
...{
_url = HttpContext.Current.Request.RawUrl;
}
public override void WriteAttribute(string name, string value, bool encode)
...{
// 如果當(dāng)前
輸出的屬性為form標(biāo)記的action屬性，則將其值替換為重寫(xiě)后的虛假URL
if (_url != null && string.Compare(name, "action", true) == 0)
...{

}
base.WriteAttribute(name, value, encode);
}
}
