1. .NET base
2. image server
3. support resizing thumb
4. use ImageResizer

deploy ResizingServer to a web server and config

  <appSettings>
    <add key="UploadRouteUrl" value="api" /><!--api routeurl http://host/{UploadRouteUrl} -->
    <add key="ApiKey" value="48DFD0EE-61A2-4CB5-B1D6-33E917A83202" /><!--when upload file use it -->
    <add key="AllowFolders" value="face,images" /><!-- folder/category  for diff biz line -->
  </appSettings>

physical path like upload/face/1508/21/5a020a4161f543f197ddc0965aeeb66d.jpg

• upload
  • category(eg:face or images in config:AllowFolders)
    • yyMM (year and month)
      • dd (date)
        • {guid}.jpg

virtual path you can use the ResizingClient to convert from a formatUrl to url format url like /u/face/b96225af353d15504302a087f4f46bb0151d1c{0}x{1}{2}.jpg url like /u/face/b96225af353d15504302a087f4f46bb0151d1c100x100c.jpg

install nuget package

Install-Package ResizingClient

upload to server

var result=ResizingUtil.Upload(File.ReadAllBytes("d:\\a.jpg"), "a.jpg", "face").Result;
Console.WriteLine(result.FormatUrl);//like /u/face/b96225af353d15504302a087f4f46bb0151d1c{0}x{1}{2}.jpg
//Assert.IsTrue(result.IsSuccess);

{0}:width {1}:height {2}:mode

mode enum:

• c:crop
• m:max
• p:pad

convert format to url

using ResizingClient;
// ...
var url1 = ResizingUtil.Format(url,100,100,ResizingMode.Pad);
var url1 = ResizingUtil.Format(url,100,100);
