Create a C# project called Apache.OpenWhisk.Example.Dotnet:
dotnet new classlib -n Apache.OpenWhisk.Example.Dotnet -lang "C#"
cd Apache.OpenWhisk.Example.DotnetInstall the Newtonsoft.Json NuGet package as follows:
dotnet add package Newtonsoft.Json -v 13.0.1Now create a file called Hello.cs with the following content:
using System;
using Newtonsoft.Json.Linq;
namespace Apache.OpenWhisk.Example.Dotnet
{
public class Hello
{
public JObject Main(JObject args)
{
string name = "stranger";
if (args.ContainsKey("name")) {
name = args["name"].ToString();
}
JObject message = new JObject();
message.Add("greeting", new JValue($"Hello, {name}!"));
return (message);
}
}
}Publish the project as follows:
dotnet publish -c Release -o outZip the published files as follows:
cd out
zip -r -0 helloDotNet.zip *Create the action
wsk action update helloDotNet helloDotNet.zip --main Apache.OpenWhisk.Example.Dotnet::Apache.OpenWhisk.Example.Dotnet.Hello::Main --kind dotnet:6.0For the return result, not only support dictionary but also support array
So a very simple hello array function would be:
using System;
using Newtonsoft.Json.Linq;
namespace Apache.OpenWhisk.Tests.Dotnet
{
public class HelloArray
{
public JArray Main(JObject args)
{
JArray jarray = new JArray();
jarray.Add("a");
jarray.Add("b");
return (jarray);
}
}
}And support array result for sequence action as well, the first action's array result can be used as next action's input parameter.
So the function can be:
using System;
using Newtonsoft.Json.Linq;
namespace Apache.OpenWhisk.Tests.Dotnet
{
public class HelloPassArrayParam
{
public JArray Main(JArray args)
{
return (args);
}
}
