以下代码在我的本地开发机器中完美运行，但在托管机器中没有。
托管计算机中的行为是在URL地址中显示此行浏览器，而不是下载文件：
我在firefox和chrome中测试了这个结果。
在我的本地机器上工作正常下载de ZIP dile。
有什么建议可以吗？

string codunicotemporal = Guid.NewGuid() + "_" + DateTime.UtcNow.ToString("yyyyMMddhhmmss");
string zipTemporal = System.Web.HttpContext.Current.Server.MapPath("//UserFiles//" + codunicotemporal) + ".zip";
ZipFile.CreateFromDirectory(OTDir, zipTemporal);
var bytes = System.IO.File.ReadAllBytes(zipTemporal);
System.IO.File.Delete(zipTemporal);
if (System.IO.Directory.Exists(OTDir))
{
System.IO.Directory.Delete(OTDir, true);
}
using (var stream = new MemoryStream(bytes))
{
string handle = Guid.NewGuid().ToString();
Session[handle] = stream.ToArray();
return new JsonResult()
{
Data = new
{
FileGuid = handle,
MimeType = "application/zip, application/octet-stream",
FileName = "OT_" + OT.OT.ToString() + ".zip"
}
};
}
}
public ActionResult Download(string fileGuid, string mimeType, string filename)
{
if (Session[fileGuid] != null)
{
byte[] data = Session[fileGuid] as byte[];
Session.Remove(fileGuid); // Cleanup session data
return File(data, mimeType, filename);
}
else
{
// Log the error if you want
return new EmptyResult();
}
}
答案 0 :(得分：0)
为了解决这个问题，我添加了MaxJsonLength = Int32.MaxValue：
return new JsonResult()
{
Data = new
{
FileGuid = handle,
MimeType = System.Net.Mime.MediaTypeNames.Application.Zip,
FileName = "OT_" + OT.OT.ToString() + ".zip",
MaxJsonLength = Int32.MaxValue
}
};
并更改流程以获得更小的zip文件：从90000 Kb到10000 kb。
