##Summary This sample demonstrates how to create and query an ASP.NET Web API service from an Office Add-in. The sample is comprised of a "Send Feedback" page, which lets a user submit feedback, and uses a Web API service to send it to the developer team.
This sample requires the following:
- Excel 2013, Word 2013, PowerPoint 2013, or Project 2013.
- Visual Studio 2013 (Update 5) or Visual Studio 2015, with Microsoft Office Developer Tools.
- Any browser that supports ECMAScript 5.1, HTML5, and CSS3, such as Internet Explorer 9, Chrome 13, Firefox 5, Safari 5.0.6, or a later version of these browsers.
Key components of the sample
The sample solution contains the following key files:
WebApi Sample project
- WebApi Sample.xml: The manifest file for the Office Add-in.
WebApi SampleWeb project
- App\Home\Home.html: The HTML user interface for the add-in.
- App\Home\Home.js: The logic that builds and sends the feedback request to the web service.
- App_Start\WebApiConfig.cs: Binds the default routing for the Web API service.
- Controllers\SendFeedbackController.cs: The business logic for the sample Web API service.
Build and debug
The sample will run right out of the box, but it won't be able to send feedback unless you configure appropriate credentials. To configure the credentials, open SendFeedbackController.cs (in the Controllers folder of the web project) and update the following constants with actual values:
const string MailingAddressFrom = "email@example.com "; const string MailingAddressTo = "firstname.lastname@example.org"; const string SmtpHost = "smtp.contoso.com"; const int SmtpPort = 587; const bool SmtpEnableSsl = true; const string SmtpCredentialsUsername = "username"; const string SmtpCredentialsPassword = "password";
- Open the solution in Visual Studio.
- Press F5 to build and deploy the sample add-in to the client that's specified as the start document (by default, Excel). To change this setting, click the WebApi Sample project in Solution Explorer and select your preferred Office application.
- On the Home ribbon, click the Open button in the Web API group.
- In the add-in, choose a rating in the drop-down list, enter some feedback, and click Send it! A toast notification opens to tell you whether your feedback was successfully sent.
- If the add-in fails to send feedback (shows a notification message with "Sorry, your feedback could not be sent"), check that you configured an appropriate email address in SendFeedbackController.cs. Alternatively, you can remove the mail-sending code, and/or replace it with a different form of sending feedback (e.g., logging to a database).
