Multiple HTML5 Video Source Blob URL Uploading

I am trying video uploading.But first user can preview the video and then upload it.The problem is multiple BLOB Url uploading via ajax and getting file as List HttpPostedFileBase .I am using ASP.NET MVC.

                    var $  source = $  ('#' + id);                     var reader = new FileReader();                     reader.readAsDataURL(this.files[0]);                     reader.onloadend = (function() {                     $  source[0].src = reader.result;                     $  source.parent()[0].load(); 

Is it possible to create a blob triggered azure function with file name pattern?

I am developing a blob triggered azure function. Following is the configuration of my “function.json” file:

{   "disabled": false,   "bindings": [     {       "name": "myBlob",       "type": "blobTrigger",       "direction": "in",       "path": "input/{name}",       "connection": "BlobConnectionString"     }   ] } 

My function is working fine. It is triggered for all files in “input” blob. Now I want to filter files by its naming pattern. For Example : I want to trigger my azure function for only those files which contains “~123~” in its name.

Is it possible to do with some change in “path” property of “function.json” file? If yes, then what should be the value of the “path” property?

Thanks,

Azure Blob and Table storage rewriting the code in a more simple way

I wrote this code, but is not very practical. I’m still new in this area of coding. Basically I’m storing an image into a blob container, and i’m saving the url in a table. I’m doing the same thing for a text file. So i would like to use dependency injection for azure connection part to make my code more practical.

Here’s my Logo Controller.

[Route("api/manage/logo")] [ApiController]  public class ManageLogoController : ControllerBase {      [HttpPost("{version}")]     public async Task<IActionResult> Post(IFormFile image, float version)     {         if (image.Length >= 1048576)         {             return BadRequest("Uploaded image may not exceed 1Mb, please upload a smaller image.");         }          var allowedExtensions = new[] {             ".png", ".jpg", "jpeg" };         string fileExt = Path.GetExtension(image.FileName);         if (allowedExtensions.Contains(fileExt))         {             try             {                 await LogoStorage.UploadFileToBlobStorage(version, image.FileName);                 return Ok(new                 {                     lenght = image.Length,                     name = image.FileName                 });             }             catch (Exception ex)             {                 return BadRequest();             }         } 

TnC Controller

[Route("api/manage/tnc")] [ApiController]  public class ManageTermCondController : ControllerBase {  [HttpPost("{version}")] public async Task<IActionResult> Post(IFormFile doc, float version) {      var allowedExtension = ".txt";     string fileExt = Path.GetExtension(doc.FileName);     if (allowedExtension.Contains(fileExt))     {         try         {             await TncStorage.UploadDocToBlobStorage(version, doc.FileName);             return Ok(new             {                 lenght = doc.Length,                 name = doc.FileName             });         }         catch (Exception ex)         {             return BadRequest();         }     }      else     {         return BadRequest("Only .txt files are allowed!");     } }    [HttpGet] public string Geti(float version) {     var x = TncStorage.GetURL(version);     if (x == null)     {         return "There's no such record";     }     else return TncStorage.GetURL(version);  } } 

I made a new class library named .Service for the following part.

 public class VersionURL : TableEntity         {             public VersionURL(string type, string version)             {                 PartitionKey = type;                 RowKey = version;             }             public VersionURL() { }             public string URL { get; set; }             public string ETag { get; set; }       }

Can i make the first and the second class more simple?
