Web Services

When connecting to external web services from within a Dataverse plugin, there are few common performance issues to be aware of. For instance, you must close connections after each use and set a reasonable timeout on the requests.

To help enforce these best practices and simplify calls to web services, you can use the IHttpService interface.

TestPlugin.csPost.cs

namespace Sample.Plugins
{
    using Imprevis.Dataverse.Plugins;
    using System.Collections.Generic;

    public class TestPlugin : Plugin<TestPluginRunner> { }

    public class TestPluginRunner : IPluginRunner
    {
        public TestPluginRunner(IHttpService httpService)
        {
            HttpService = httpService;
        }

        public IHttpService HttpService { get; }

        public void Execute()
        {
            var posts = HttpService.Send<List<Post>>("GET", "https://jsonplaceholder.typicode.com/posts");

            foreach (var post in posts)
            {
                // Do something!
            }
        }
    }
}

namespace Sample.Plugins
{
    public class Post
    {
        public int UserId { get; set; }
        public int Id { get; set; }
        public string Title { get; set; }
        public string Body { get; set; }
    }
}
