在MVC 6中調整上傳圖像的最佳方式是什麼?我想存儲圖像的多個變體(如小,大等),以便能夠選擇稍後顯示的圖像。在MVC 6中調整上傳圖像的大小6
這是我的行爲代碼。
[HttpPost]
public async Task<IActionResult> UploadPhoto()
{
if (Request.Form.Files.Count != 1)
return new HttpStatusCodeResult((int)HttpStatusCode.BadRequest);
IFormFile file = Request.Form.Files[0];
// calculate hash
var sha = System.Security.Cryptography.SHA256.Create();
byte[] hash = sha.ComputeHash(file.OpenReadStream());
// calculate name and patch where to store the file
string extention = ExtentionFromContentType(file.ContentType);
if (String.IsNullOrEmpty(extention))
return HttpBadRequest("File type not supported");
string name = WebEncoders.Base64UrlEncode(hash) + extention;
string path = "uploads/photo/" + name;
// save the file
await file.SaveAsAsync(this.HostingEnvironment.MapPath(path));
}
謝謝!正是我需要的! –
@Phill偉大的鏈接,謝謝,我發現了唯一的vNext圖像。但是「新大小」是System.Drawing部分嗎? – Alex
@voo當前的Nuget仍然需要System.Drawing,但API正在改變V2來放棄這個約束。 https://github.com/JimBobSquarePants/ImageProcessor#api-changes – Phill
