我通过MVC,jQuery,Ajax创建了文件上传器。但它正在发挥作用 仅适用于1到3千字节的文件,并且不适用于较大的hajn文件。如何上传更大尺寸的文件?
HTML:
<input type="file" name="bfile" size="50" id="bfile"/>
<input type="butt
AppAttachmentsController-controller代码:
public string file_upload(string file_name, string file_binary)
{
byte[] byteArray = System.Text.Encoding.ASCII.GetBytes(file_binary);
MemoryStream stream = new MemoryStream(byteArray);
string path=Server.MapPath(Url.Content("~/upload/file"))+"\\"+file_name;
using (var fileStream = new FileStream(path, FileMode.Create))
stream.CopyTo(fileStream);
return "1";
}
jQuery,Ajax :
function AttachemtPost() {
var file_name = $("#bfile").val();
var data = "file_name=" + file_name;
var file = document.getElementById('bfile').files[0];
var file_binary = file.getAsBinary();
var file_size = file.fileSize;
var file_text = file.getAsText("");
alert('file :' + file_binary);
alert('file size:' + file_size);
data = "file_name=" + file_name + "&file_binary=" + file_binary;
ajaxlocalcall2(null, "POST", '@Url.Content("~/AppAttachments/file_upload")', data, "", "", "html", "oncontactinfosave");
}

您可以尝试在web.config中增加允许的最大请求大小,默认情况下为4MB:
<httpRuntime maxRequestLength="size in kbytes" />
此外,如果您在IIS 7+中托管应用程序,则应设置request limit:
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="size in bytes" />
</requestFiltering>
</security>
</system.webServer>
