Khoush ion download multiple files

Using the cancelAll Activity call, all requests still pending can be easily cancelled:. Ion also lets you tag your requests into groups to allow for easy cancellation of requests in that group later:. Using Charles Proxy on your desktop computer in conjunction with request proxying will prove invaluable for debugging!

Ion operations return a ResponseFuture , which grant access to response properties via the Response object. The Response object contains the headers, as well as the result:. There's hundreds of apps using ion. Feel free to contact me or submit a pull request to add yours to this list.

I thought that if I am able to search multiple ItemId's at once then there must be a way to easily download them. You should look into Teamcenter's briefcase functionality or multisite for data transfer to the remote site. Especially since this is export control data - it would be preferrable to keep it within the security data model - otherwise you can't guarantee unathorized exports once the data is no longer under access control and electronic audit.

View This Post. October 21, at PM. Downloading Multiple Documents. Thanks in advance for any help. Regards, Alistair. The custom component will also include a list that previews all of the files that have currently been added, as well as the ability to reorder those files. We will be covering just what is required on the client side to send the files to a server, we won't be implementing the server-side where you would want to actually do something with those files I likely will write another tutorial on doing that with NestJS soon.

It is also worth noting that this functionality ties into a standard file input component, i. Before you go through this tutorial, you should have at least a basic understanding of Ionic concepts. You must also already have Ionic set up on your machine, and an Ionic project created. If you're not familiar with Ionic already, I'd recommend reading my Ionic Beginners Guide first to get up and running and understand the basic concepts.

If you want a much more detailed guide for learning Ionic, then take a look at Building Mobile Apps with Ionic. As I mentioned, we will be using the ng2-file-upload package to provide the functionality we will be making use of. In order to install that, you will need to run the following command in your project:. This package will provide us with two directives. The ng2FileDrop directive will allow us to create an area where a user can drag and drop multiple files, and the ng2FileSelect directive will allow us to create a standard input button that allows for selecting multiple files.

It is not entirely necessary to create a custom component. You could just use these directives directly in your templates. However, we will be building out a few more features around this functionality, so we are going to bundle that into its own component.

With the component generated, we can start to work through implementing the functionality. Before we do that, I think it is important to have a basic understanding of the different ways in which we can encode and send data through forms. When data is sent with the default encoding it is basically treated like a long query string that you would be able to send through a URL.

This method for sending data is more robust, but it does have more overhead than the simpler URL encoded approach. It is not really important to understand the particulars of how this all works behind the scenes, but it is useful to understand that there is a reason for the existence of these different encoding types.

Instead, we are manually creating a FormData object and assigning values to it. Now let's work on implementing the upload component itself.
