除了其中"文件上传"部分，其它为weui-uploader的示例程序。
有些时候还是必须传入其它参数的，保存数据库时才知道这个附档关联到哪个文档中。
[HttpPost]
public JsonResult ImageUpload(FormContext context)
{
//文件
HttpPostedFileBase fileData = Request.Files[0];
//其它参数
string appId = Request["appId"];
string random = Request["random"];
string sign = Request["sign"];
string imgType = Request["imgType"];
if (fileData != null)
{
try
{
//保存文件(也可以得到文件流进行处理)
string fileName = Path.GetFileName(fileData.FileName);//原始文件名称
string fileExtension = Path.GetExtension(fileName).ToLower();
string newFileName =Guid.NewGuid().ToString().Replace("-", "")+fileExtension;
fileData.SaveAs(Server.MapPath("~/upload/" + newFileName));
///to do list 保存到数据库 今天就不玩了
return Json(new { code = 1, list = newFileName, msg = "上传成功~" });
}
catch (Exception ex)
{
return Json(new { code = 0, msg = ex.Message });
}
}
else
{
return Json(new { code = 0, msg = "图片上传失败，请稍后再试~" });
}
}
后台能保存到本地文件了，其它的操作就简单了。
