服务器图片（绝对地址） 客户端显示问题
做個參考吧,跟之前的有個問題類似

handler2.ashx
<%@ WebHandler Language="C#" Class="Handler2"%>
using System;
using System.Web;
using System.IO;
using System.Drawing;
publicclass Handler2 : IHttpHandler {
??? publicvoid ProcessRequest(HttpContext context)
??? {
??????? string path = context.Request.QueryString["path"];
??????? if (!string.IsNullOrEmpty(path))
??????? {
??????????? FileStream fs =new FileStream(@path, FileMode.Open, FileAccess.Read);
??????????? Bitmap myImage =new Bitmap(fs);
??????????? //輸出到瀏覽器
??????????? MemoryStream ms =new MemoryStream();
??????????? myImage.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
??????????? context.Response.ClearContent();
??????????? context.Response.ContentType ="image/Jpeg";
??????????? context.Response.BinaryWrite(ms.ToArray());
??????? }
??? }
??? publicbool IsReusable {
??????? get {
??????????? returnfalse;
??????? }
??? }
}
?
?
?
幾個要注意的地方：
URL帶有中文?
?
頁面后臺代碼:s
public string GoUen(object str)
??????? {
??????????? string Result="";
??????????? if (str != null)
??????????? {
??????????????? Result = Server.UrlEncode(str.ToString());
??????????? }
??????????? return Result;
??????? }
?
前臺調用:
<img runat="server" src= '<%#"Handler1.ashx?path="+GoUen(Eval("Address"))%>'
?
hasx接收時:
string path = HttpContext.Current.Server.UrlDecode(context.Request.QueryString["path"]);
