Get the Report →DataBind Wijmo Grid to SFTP Data
Provide real-time SFTP data to interactive controls.
The Connect Server enables you to use Web services to connect to and query SFTP data. This article details how to import an OData feed of SFTP data into Wijmo Grid.
Configuring Connect Server
To work with live SFTP data in Wijmo Grid, we need to connect to SFTP from Connect Server, provide user access to the new virtual database, and create OData endpoints for the SFTP data.
Add a Connect Server User
Create a User to connect to SFTP from Wijmo Grid through Connect Server.
- Click Users -> Add
- Configure a User
- Click Save Changes and make note of the Authtoken for the new user
Connect to SFTP from Connect Server
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open Connect Server and click Connections
- Select "SFTP" from Available Data Sources
-
Enter the necessary authentication properties to connect to SFTP.
SFTP can be used to transfer files to and from SFTP servers using the SFTP Protocol. To connect, specify the RemoteHost;. service uses the User and Password and public key authentication (SSHClientCert). Choose an SSHAuthMode and specify connection values based on your selection.
Set the following connection properties to control the relational view of the file system:
- RemotePath: Set this to the current working directory.
- TableDepth: Set this to control the depth of subfolders to report as views.
- FileRetrievalDepth: Set this to retrieve files recursively and list them in the Root table.
- Click Save Changes
- Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).
Add SFTP OData Endpoints in Connect Server
After connecting to SFTP, create OData Endpoints for the desired table(s).
- Click OData -> Tables -> Add Tables
- Select the SFTP database
- Select the table(s) you wish to work with and click Next
- (Optional) Edit the resource to select specific fields and more
- Save the settings
(Optional) Configure Cross-Origin Resource Sharing (CORS)
When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.
- Enable cross-origin resource sharing (CORS): ON
- Allow all domains without '*': ON
- Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
- Access-Control-Allow-Headers: Authorization
Save the changes to the settings.
Connect to SFTP Data using Wijmo Grid
Create a Real-Time Grid
Follow the steps below to consume SFTP data from the Wijmo JavaScript controls:
-
Load the required Wijmo, jQuery, and Knockout libraries:
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script> <script src="http://code.jquery.com/ui/1.11.0/jquery-ui.min.js"></script> <!--Theme--> <link href="http://cdn.wijmo.com/themes/aristo/jquery-wijmo.css" rel="stylesheet" type="text/css"> <!--Wijmo Widgets CSS--> <link href="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.css" rel="stylesheet" type="text/css"> <!--Wijmo Widgets JavaScript--> <script src="http://cdn.wijmo.com/jquery.wijmo-open.all.3.20161.90.min.js"></script> <script src="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.js"></script> <script src="http://cdn.wijmo.com/interop/wijmo.data.ajax.3.20161.90.js"></script> <!--Knockout JS Library--> <!-- Both of the links below can work --> <script src="http://cdn.wijmo.com/wijmo/external/knockout-2.2.0.js"></script> <!--<script src="http://cdn.wijmo.com/amd-js/3.20161.90/knockout-3.1.0.js"></script>--> <!--Wijmo Knockout Integration Library--> <script src="http://cdn.wijmo.com/interop/knockout.wijmo.3.20161.90.js"></script>

Create a ViewModel and connect to it using the ODataView. You will need to replace the placeholder values for
the URL of the API Server, an API Server user, and the authtoken for that user.
<script id="scriptInit"> $.support.cors = true; var viewModel; function ViewModel() { var mydirectoryView = new wijmo.data.ODataView("http://MyServer:MyPort/api.rsc/MyDirectory", { ajax: { dataType: "jsonp", username: "MyUser", password: "MyAuthtoken", data: { "$inlinecount": null } }, pageSize: 10 }); mydirectoryView.refresh(); mydirectoryView.nextPage(); this.mydirectory = mydirectoryView; this.prevPage = function () {mydirectoryView.prevPage();}; this.nextPage = function () {mydirectoryView.nextPage();}; } $(document).ready(function () { viewModel = new ViewModel(); ko.applyBindings(viewModel, $(".container").get(0)); }); </script>
-
DataBind: Below is a simple table with some paging buttons, which you can paste into the body section of your markup.
<h2>Connect to Live SFTP Data in Real Time</h2> <h3>MyDirectory</h3> <div> <button title="previous page" class="pagebuttons" data-bind="click: prevPage, button: {}"> <span class="ui-icon ui-icon-seek-prev" /> </button> <button title="next page" class="pagebuttons" data-bind="click: nextPage, button: {}"> <span class="ui-icon ui-icon-seek-next" /> </button> </div> <table id="demo-grid" data-bind="wijgrid: { data: mydirectory, showFilter: true, allowPaging: true, pagerSettings: { position: 'none'}, columnsAutogenerationMode: 'append', }" > </table>
At this point, you may be prompted to re-enter the username and authtoken. After doing so, a resulting table or grid should appear, as seen below. You can filter and sort through pages of SFTP data.
