我目前使用 asp.net mvc 4 ,并使用 jquery-file-upload 上传图片,如果我这样初始化:
$('#fileupload').fileupload();
$('#fileupload').fileupload('option', {
//url: '/Admin/News/Create',
maxFileSize: 500000000,
acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i,
maxNumberOfFiles: 1,
resizeMaxWidth: 1920,
resizeMaxHeight: 1200,
});
选择图片文件时,可以在浏览器中预览图片,但在mvc Action Request.Files.Count中为0,表示没有上传文件。如果我这样初始化:
//$('#fileupload').fileupload();
$('#fileupload').fileupload('option', {
//url: '/Admin/News/Create',
maxFileSize: 500000000,
acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i,
maxNumberOfFiles: 1,
resizeMaxWidth: 1920,
resizeMaxHeight: 1200,
});
我无法预览图像,但 mvc 操作获取文件,有人知道为什么吗?控制器的邮政编码:
[HttpPost]
[ValidateInput(false)]
public ActionResult Create(NewsViewModel model, FormCollection form)
{
if (ModelState.IsValid)
{
//....
// upload image
foreach (string file in Request.Files)
{
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
if (hpf.ContentLength == 0)
continue;
string path = Path.Combine(Server.MapPath("~/Uploads/News/"),GUID.NewGuid()+ Path.GetExtension(hpf.FileName));
hpf.SaveAs(path);
data.ImagePath = path;
_iNewsService.UpdateNews(data);
}
}
}
