当我保存图像时,图像成功保存到数据库中,但是它需要这样的完整图像路径:C:\ Users .... \ Uploads \ employee.jpg我不希望这样,我需要像这样保存图像路径这个〜Uploads \ employee.jpg以及特定的文件夹和相同的路径应该保存在数据库中,如果有人在保存正确的路径后向我显示我如何查看该图像。因为这个我有错误:
“不允许加载本地资源:file:/// C:/ ......”
谢谢!
我的代码:
[HttpPost]
public async Task<IActionResult> Create(Photos photos)
{
if (ModelState.IsValid)
{
var filePath =
Path.Combine(_appEnvironment.ContentRootPath,
"Uploads", photos.FormFile.FileName);
photos.PhotoPath = filePath;
using (var stream = new FileStream(filePath, FileMode.Create))
{
await photos.FormFile.CopyToAsync(stream);
}
_context.Add(photos);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
ViewData["NewsId"] = new SelectList(_context.News, "NewsId",
"NewsBigTitle", photos.NewsId);
return View(photos);
}

分解代码:
var localPath = Path.Combine("Upload", "file.jpg");
var fullPath = Path.Combine(_appEnvironment.ContentRootPath, localPath);
将localPath
保存到PhotoPath
修改
好吧,现在在视图中显示PhotoPath
,并将其定位为文件流操作。
[HttpGet("path/{image}")]
public FileStreamResult Image(string image)
{
var result = new FileStreamResult(new FileStream(
Path.Combine(_appEnvironment.ContentRootPath, image),
FileMode.Open,
FileAccess.Read), "image/<your_mime>");
return result;
}
我认为最好的方法是使用以下格式的http://example.com/path/image.jpg
创建一个新字符串并将其绑定到src
。
您不能使用以下命令来定位动态添加的文件:~/path/image.jpg
作为来源。

确保已在IFileProvider
类的Uploads
方法中配置Configure
指向您的Startup
文件夹:
app.UseStaticFiles(); // Default one
// Adding one more location - folder named `Uploads` to be a custom static files folder.
// The `Uploads` folder is available in the content root directory of the application (where your `Controllers` folder.
// You can point it of course inside `wwwroot` - use `env.WebRootPath` instead)
app.UseStaticFiles(new StaticFileOptions {
FileProvider = new PhysicalFileProvider(Path.Combine(env.ContentRootPath, "Uploads")),
RequestPath = new PathString("/Uploads")
});
完成此操作后,您应该可以在控制器操作中以这种方式上传文件:
var filePath = Path.Combine(_environment.ContentRootPath, "Uploads", photos.FormFile.FileName);
using (var stream = new FileStream(filePath, FileMode.Create))
{
await photos.FormFile.CopyToAsync(stream);
}
