3.二维码生成的后台操作
public ActionResult EwmImg() {
try
{
var file = Request.Files[0]; //获取选中文件
var filecombin = file.FileName.Split('.');
//文件名字
string filename = Path.GetFileName(file.FileName);
if (file == null || filename.IndexOf("&") != -1 || String.IsNullOrEmpty(file.FileName) || file.ContentLength == 0 || filecombin.Length < 2)
{
return Json(new
{
fileid = 0,
src = "",
name = "",
msg = "上传出错 请检查文件名 或 图片格式是否符合"
});
}
//定义本地路径位置
string local = "upload\\ewm\\img\\";
string localPath = Path.Combine(HttpRuntime.AppDomainAppPath, local);
if (!System.IO.Directory.Exists(localPath))
System.IO.Directory.CreateDirectory(localPath);
string newPath = localPath + filename;
file.SaveAs(newPath);
//保存图片
return Json(new
{
src = newPath.Trim().Replace("\\", "|"),
name = filename,
// 获取文件名不含后缀名
msg = "上传成功"
});
}
catch { }
return Json(new
