问题:
1、同一台机器上部署了两个虚拟目标,A虚拟目录里对图片进行上传删除等操作,图片上传的位置在A虚拟目录中,例如:在AdvertisingImg文件夹中。
2、而B虚拟目录要求可以看到此图片。虽然是同一台机器,但直接用绝对路径查看图片是不行的。
解决方法:
http://localhost/A/AdvertisingImg/图片名称.后缀
3、打开绝对路径图片:
/// <summary>
/// 下载JPG文件
/// </summary>
/// <param name="strFileFullPath">文件绝对路径路径</param>
/// <param name="page">下载的页面</param>
/// <param name="strFileName">要保存的文件名</param>
public static void DownloadLocalJpgFile(string strFileFullPath, System.Web.UI.Page page,string strFileName)
{
System.Web.HttpResponse response = page.Response;
System.IO.FileInfo file = new System.IO.FileInfo(strFileFullPath);
if (!file.Exists)
{
return;
}
response.HeaderEncoding = System.Text.Encoding.GetEncoding("gb2312");
response.Charset = "GB2312";
response.Clear();
response.Charset = "GB2312";
response.ContentEncoding = System.Text.Encoding.UTF8;
response.AddHeader("Content-Disposition", "attachment;filename=" + strFileName);
response.AddHeader("Content-Length", file.Length.ToString());
response.ContentType = "image/jpeg";
response.WriteFile(file.FullName);
response.End();
}
