Question

我目前正在ASP.Net Core中建立一个电子商务网站。我遇到了一些困境。我先添加产品，填写表单，然后尝试提交表单时，它会显示我的404 /访问页面。

这在Ubuntu 16.04 Web服务器上处于生产模式。在本地测试，效果很好。

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);
}

我怀疑您在表格中包含该文件？因此该文件在模型中，因此它不会找到路线。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
