一般处理程序接收上传文件问题

[槿木_熙]

接收程序如下：
public class InventoryUpload : IHttpHandler
{
//服务器默认保存路径
private string strServerPath = ConfigurationManager.AppSettings["InventorPath"];//@"D:\InventorUpload\inventor\";
private string strFilePath = HttpContext.Current.Request.ApplicationPath;
public InventoryUpload()
{
strFilePath = "\\upload\\inventory\\";//(strFilePath == "" ? "~" : strFilePath) + "\\upload\\inventory\\";
strServerPath = System.Web.HttpContext.Current.Server.MapPath(".") + "\\upload\\inventory\\";
if (!Directory.Exists(strServerPath))
Directory.CreateDirectory(strServerPath);
}

public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string queryString = "";
foreach (string key in context.Request.QueryString.AllKeys)
{
queryString = context.Request.QueryString[key];
}
string folder = strServerPath + queryString + "\\";
try
{
if (!string.IsNullOrWhiteSpace(queryString))
{
if (!Directory.Exists(folder))
Directory.CreateDirectory(folder);
}
}
catch
{
context.Response.Write(JsonConvert.SerializeObject(new { code = false, msg = "创建目录失败", data = "" }));
}
// 获取 http提交上传的文件, 并改名保存
foreach (string key in context.Request.Files.AllKeys)
{
HttpPostedFile file = context.Request.Files[key];
string newFilename = DateTime.Now.Ticks + file.FileName.Substring(file.FileName.LastIndexOf('.'));
string fileUrl = folder + newFilename;
string filePath = Path.Combine(strFilePath + queryString + "\\", newFilename);
try
{ //文件保存并返回相对路径地址
file.SaveAs(folder + newFilename);
context.Response.Write(JsonConvert.SerializeObject(new { code = true, msg = "保存成功", data = new { fileNmae = newFilename, url = fileUrl, path = filePath.Replace("/", "") } }));
}
catch (Exception ex)
{
context.Response.Write(JsonConvert.SerializeObject(new { code = false, msg = ex.Message + ",Fail", data = "" }));
}
}
}

public bool IsReusable
{
get
{
return false;
}
}
}


使用layui.upload批量上传时，第一次上传会提示有一两个文件进程被占用，无法保存。有遇到过这种问题的吗。有没有好的解决方法？？

在foreache 里里面怎么写了response 我第二个文件还没保存你就返回了？

批量上传多少个文件会请求多少次。你不用管foreach，直接HttpPostedFile file = context.Request.Files[0]。每次请求Files里只会有一个文件

为什么不一次传上去呢。response 上面创建目录失败 后面加上 response.writeEnd 后面加上filescount的判断 怀疑你提交了空文件。。。

文件saveas的后面还可以加上 Thread.Sleep(500)
