ASP.Net Core Post 访问被拒绝

Question

我目前正在使用 ASP.Net Core 制作电子商务网站。我遇到了一个小难题。我去添加一个产品，填写表格，然后当我尝试提交表格时，它会打开我的 404/access 页面。

这是在 Ubuntu 16.04 Web 服务器上的生产模式。本地测试，效果不错。

代码：

[HttpGet]
public IActionResult AddProduct()
{
    return View(new ProductAddModel());
}

[HttpPost]
public async Task<IActionResult> AddProduct(ProductAddModel model, IFormFile file)
{
    if (ModelState.IsValid)
    {
        var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot/images/Products", file.FileName);
        using (var stream = new FileStream(path, FileMode.Create))
        {
            await file.CopyToAsync(stream);
        }

        var user = await userManager.FindByNameAsync(User.Identity.Name);
        ProductDataModel dataModel = new ProductDataModel()
        {
            Name = model.Name,
            ShortDescription = model.ShortDescription,
            Description = model.Description,
            Category = model.Category,
            Game = model.Game,
            Price = model.Price,
            ImagePath = file.FileName,
            DeveloperUserId = user.Id
        };
        context.Products.Add(dataModel);
        context.SaveChanges();
        return RedirectToAction("Products", "Admin");
    }
    return View(model);
}

这里有一些屏幕截图。 Add Product 404/Access Denied

我怀疑您在表单中包含该文件？所以文件在模型中，所以它不会找到路径。在模型中添加 IFormFile：

[HttpPost]
public async Task<IActionResult> AddProduct(ProductAddModel model)
{
    if (ModelState.IsValid)
    {
        var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot/images/Products", model.File.FileName);
        using (var stream = new FileStream(path, FileMode.Create))
        {
           await model.File.CopyToAsync(stream);
        }

        var user = await userManager.FindByNameAsync(User.Identity.Name);
        ProductDataModel dataModel = new ProductDataModel()
        {
            Name = model.Name,
            ShortDescription = model.ShortDescription,
            Description = model.Description,
            Category = model.Category,
            Game = model.Game,
            Price = model.Price,
            ImagePath = model.File.FileName,
            DeveloperUserId = user.Id
        };
        context.Products.Add(dataModel);
        context.SaveChanges();
        return RedirectToAction("Products", "Admin");
    }
    return View(model);
}

如果这不起作用，请显示 Startup.cs 和 AddProduct.cshtml
