图像上传在服务器中不起作用。在localhost工作正常

Question

所以，这段代码在localhost中工作得很好。它删除以前的图像并上传新的图像。但是，它在服务器上不做任何事任何线索？

我已经使用AJAX进行asynchorous调用顺便说一下，如果这有所作为。

var db=Database.Open("StarterSite"); 
    var contentQuery="Select * from Contents where id [email protected]"; 
    var content=db.QuerySingle(contentQuery,"1"); 
    var message=""; 
    var imgCount=0; 
    var alreadyExist=false; 

    try{ 
     if (IsPost && Request.Files.Count > 0) { 
      bool deleteSuccess = false; 
      var fileName = ""; 
      var photoName = ""; 
      var fileSavePath = ""; 
      var uploadedFile = Request.Files[0]; 
      var toDelete=Request["toDelete"]; 
      var toUpload=Request["toUpload"]; 

      if(uploadedFile.ContentLength>0){ 
       @******************DELETE***************@ 
        var fullPath = Server.MapPath("~/img/" + toDelete); 
        if (File.Exists(fullPath)) 
         { 
           File.Delete(fullPath); 
           deleteSuccess = true; 
         } 
      @****************UPLOAD*******************@ 
        fileName = Path.GetFileName(uploadedFile.FileName); 
        fileSavePath = Server.MapPath("~/img/" + 
         fileName); 
        uploadedFile.SaveAs(fileSavePath); 
        var updateQuery="Update Contents Set "+toUpload +"[email protected]"; 
        db.Execute(updateQuery, fileName); 
        //Response.Redirect("editMode.cshtml"); 
      } 
     } 
    } 
    catch(HttpException ex){ 
     message="Image size you selected was too large. Please select a different Image."; 
    }
