PowerAutomate のカスタムコード作成を支援するためのライブラリです。
- ScriptBase 及び IScriptContext の実装
プロジェクトの作成とライブラリの参照
dotnet new console
dotnet add package PowerAutomateCustomCodeHelper
Script.cs の作成
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Security.Cryptography;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using Newtonsoft.Json.Linq;
using PowerAutomateCustomCodeHelper;
public class Script : ScriptBase
{
public override async Task<HttpResponseMessage> ExecuteAsync()
{
await Task.CompletedTask;
return Context.OperationId switch
{
"ComputeMD5" => GetComputeMd5(),
_ => new HttpResponseMessage(HttpStatusCode.BadRequest)
};
}
private HttpResponseMessage GetComputeMd5()
{
// コンテキストからクエリ文字列 value を参照する
var queryString = Context.Request.RequestUri?.Query;
if (string.IsNullOrEmpty(queryString))
{
return new HttpResponseMessage(HttpStatusCode.BadRequest);
}
var query = HttpUtility.ParseQueryString(Context.Request.RequestUri.Query);
var origin = query.AllKeys.Any(_ => _ == "value")
? string.IsNullOrEmpty(query["value"]) ? string.Empty : query["value"]
: string.Empty;
// MD5 ハッシュを計算しレスポンスに格納する
var hashedString = MD5.Create().ComputeHash(Encoding.UTF8.GetBytes(origin));
var response = new HttpResponseMessage(HttpStatusCode.OK);
response.Content = CreateJsonContent((new JObject
{
["origin"] = origin,
["hashedString"] = hashedString,
}).ToString());
return response;
}
}Program.csの変更
using System;
using System.Threading.Tasks;
using PowerAutomateCustomCodeHelper;
class Program
{
static async Task Main(string[] args)
{
var script = TestScriptHelper.CreateGetRequest<Script>("https://api.contoso.com/MD5?value=hoge", "ComputeMD5");
var response = await script.ExecuteAsync();
Console.WriteLine(await response.Content.ReadAsStringAsync());
}
}
