Question

我有一个应用程序，允许管理员上传商店的图像。 Currenly它使用服务器路径在本地工作：

string ImageName = System.IO.Path.GetFileName(file.FileName);
string physicalPath = Server.MapPath("~/Images/"+ImageName); //which is local project folder.

但是，当我发布它时，它不再显示上传的图像或上传。如何更改要在服务器上存储的服务器路径，例如，如果站点地址是www.google.com，是否有办法从服务器而不是本地进行此操作？

以下是完整的图片上传代码：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "CustomerID,DiscountLevelID,LoyaltyLevelID,CustomerCompanyName,CustomerName,CustomerSurname,CustomerGUID,CustomerStatus,CustomerAddress,CustomerTel,CustomerCel,CustomerNumber,CustomerContact,CustomerLogo,CustomerLogoPath,LastStoreCustomerSyncID")] Customer customer, HttpPostedFileBase file)
{
    if (ModelState.IsValid)
    {
        if (file != null)
        {
            string ImageName = System.IO.Path.GetFileName(file.FileName);
            string physicalPath = Server.MapPath("~/Images/");
            if (!Directory.Exists(physicalPath))
                Directory.CreateDirectory(physicalPath);
            string physicalFullPath = Path.Combine(physicalPath, ImageName);
            file.SaveAs(physicalFullPath);

            customer.CustomerLogo = ImageName;
            customer.CustomerLogoPath = physicalFullPath;
            db.Customers.Add(customer);
            db.SaveChanges();
        }
        return RedirectToAction("Index");
    }
    return View(customer);
}

使用它在索引中显示图像：

<td><img src=@Url.Content(@item.CustomerLogo) width="100" height="100" /></td>

Answer 1

要查看图片，您可以尝试这样：

<img src= "@Url.Content(@Model.CustomerLogo)" alt="Image" width="100" height="100" />

@Url.Content接受相对路径。

要上传图片，您可以尝试这样：

public class FileModel
{
    [Required]
    public HttpPostedFileBase File { get; set; }
}

查看：

@model MvcApplication.Models.FileModel

@using (Html.BeginForm("Upload", "File", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <div>
        @Html.LabelFor(x => x.File)
        @Html.TextBoxFor(x => x.File, new { type = "file" })
        @Html.ValidationMessageFor(x => x.File)
    </div>

    <button type="submit">Upload</button>
}

<强>控制器：

public ActionResult Upload(FileModel model)
{
    string fileName = Path.GetFileName(model.File.FileName);
    string path = Server.MapPath("~/Files/");

    if (!Directory.Exists(path))
        Directory.CreateDirectory(path);

    string fullPath = Path.Combine(path, fileName);

    model.File.SaveAs(fullPath);
    return View();
}
