我有它的工作..但我注意到，一旦我上传的文件越来越大(大约4000k)控制器不会被调用..
所以我添加在chunking哪个修复了这个问题..但现在当我打开的文件，其完整的垃圾字符…
那么什么是正确的方式上传大文件与plupload / MVC 4？
这是我当前的代码
$(document).ready(function () {
var uploader = new plupload.Uploader({
runtimes: 'html5',browse_button: 'pickfiles',container: 'container',// max_file_size: '20000mb',url: '@Url.Action("Upload","Home")',chunk_size: '4mb',//filters: [
// { title: "Excel files",extensions: "xls,xlsx" },// { title: "Text files",extensions: "txt" }
//],multiple_queues: true,multipart: true,multipart_params: { taskId: '' }
});
和控制器
[HttpPost]
public ActionResult Upload(int? chunk,string name,string taskId)
{
string filePath = "";
var fileUpload = Request.Files[0];
var uploadPath = Server.MapPath("~/App_Data/Uploads");
chunk = chunk ?? 0;
string uploadedFilePath = Path.Combine(uploadPath,name);
var fileName = Path.GetFileName(uploadedFilePath);
try
{
using (var fs = new FileStream(filePath,chunk == 0 ? FileMode.Create : FileMode.Append))
{
var buffer = new byte[fileUpload.InputStream.Length];
fileUpload.InputStream.Read(buffer,buffer.Length);
fs.Write(buffer,buffer.Length);
}
//Log to DB for future processing
InstanceExpert.AddProcessStart(filePath,Int32.Parse(taskId));
}
解决方法
在web.config你需要这些(2GB四周)：
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" maxRequestLength="2147483647" executionTimeout="1600" requestLengthDiskThreshold="2147483647" />
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="2147483647" />
</requestFiltering>
</security>
...
</system.web>
