Tinode Chatbot Example for .Net or .NetCore

This is a rudimentary chatbot for Tinode using gRPC API. It's written in C# as a demonstration that the API is language-independent.

The chat bot subscribes to events stream using Plugin API and logs in as a regular user. The event stream API is used to listen for creation of new accounts. When a new account is created, the bot initiates a p2p topic with the new user. Then it listens for messages sent to the topic and responds to each with a random quote from quotes.txt file.

Nuget: Tinode.ChatBot

Generated files are provided for convenience in a separate folder. You may re-generate them if needed:

for Windows

generate_proto.bat

for Linux/Mac

generate_proto.sh

There is already a .net standard library implement for chatbot as "Tinode.ChatBot", and there are two applicaion implentat for .net framework4.6.1 and .net core2.0 they are "Tinode.ChatBot.DemoNet46" and "Tinode.ChatBot.DemoNetCore".

you can use VistualStudio2017 to open it : ChatBot.sln

if you want define your own bot, Just follow these steps:

Implement your own IBotResponse interface,such as :

    /// <summary>
    /// ChatBot reply interface, you can define your own chat reply logic.
    /// </summary>
    public interface IBotResponse
    {
        /// <summary>
        /// ChatBot Accept Message, and give a resonable reply.
        /// </summary>
        /// <param name="message">message to chatbot</param>
        /// <returns>message reply by chatbot</returns>
        Task<ChatMessage> ThinkAndReply(ServerData message);
    }

API useage:

New a bot instance:

ChatBot bot = new ChatBot(serverHost: host, listen: listen, schema: schemaArg, secret: secretArg);
//Event handlers
bot.ServerDataEvent += Bot_ServerDataEvent; //ServerData Event, message comming
bot.ServerMetaEvent += Bot_ServerMetaEvent; //ServerMeta Event, friend list message etc.
bot.ServerPresEvent += Bot_ServerPresEvent; //ServerPres Event, someone is begion typing message
bot.CtrlMessageEvent += Bot_CtrlMessageEvent; //CtrlMessage Event, every acton with server will response a ctrl message
bot.LoginSuccessEvent += Bot_LoginSuccessEvent; //LoginSuccess Event, when login success
bot.LoginFailedEvent += Bot_LoginFailedEvent;  //LoginFailed Event, when login failed
bot.DisconnectedEvent += Bot_DisconnectedEvent;  //when disconnected with the server, the bot will reconnect automatically.
//your should set your chatserver's http base url and api access key to handle larget file upload
bot.SetHttpApi("your chat server http base url", "your api key");
bot.BotResponse = new BotReponse(bot);  //your response implement with IBotResponse
bot.Start().Wait();  //start your bot

handle new message, use MsgBuilder, new message comes with ServerData, so you need to is just parse it to ChatMessage, to do it is simple as below:

 var msg = MsgBuilder.Parse(message);

get chatbot chat/friend list, you can access it with bot.Subscribers
build your response message, such as formatted text, image, file etc. you can use MsgBuilder to do that just like StringBuilder:

MsgBuilder builder = new MsgBuilder();
//add text with bold
builder.AppendText("Hi,this is bold\n", isBold: true);
//add text with italic
builder.AppendText("Hi,this is italic\n", isItalic: true);
//add text with deleted
builder.AppendText("Hi,this is deleted\n", isDeleted: true);

//add text with code style
builder.AppendText("int a=100;\nint b=a*100-90;\n", isCode: true);
//add link
builder.AppendText("https://google.com\n", isLink: true);
//add domain
builder.AppendText("baidu.com\n", isLink: true);
//add mention message
builder.AppendText("@tinode\n", isMention: true);
//add hashtags
builder.AppendText("#Tinode\n", isHashTag: true);
builder.AppendText("\n\nnext is image\n");
//add image message
builder.AppendImage("a.png", "image/png", 0, 0, "iamge with base64 value");
builder.AppendText("\n\nnext is file\n");
//add file message
builder.AppendFile("a.txt", "text/plain", "file with base64 value");
//add attachment file message
builder.AppendAttachment(attachmentInfo);

//Send form with button
MsgBuilder builder = new MsgBuilder();
builder.AppendText("What's your gender?", isBold: true, isForm: true);
builder.AppendText("Male", isButton: true, buttonDataName: "male", buttonDataVal: "user click male");
builder.AppendText("Female", isButton: true, buttonDataName: "female", buttonDataVal: "user click female");
builder.AppendText("Not Sure", isButton: true, buttonDataName: "NA", buttonDataVal: "user click NA");


responseMsg = builder.Message;

you can also build simple message with static methods of MsgBuilder:

//Send Image File
responseMsg = MsgBuilder.BuildImageMessage("a.png", "image/png", 47, 48, "image with base64 value", "this is a image by chatbot");

//Send file
responseMsg = MsgBuilder.BuildFileMessage("a.txt", "text/plain", "file with base64 value", "this is a file by chatbot");

//Send text
responseMsg = MsgBuilder.BuildFileMessage("this your text message with line break\n this is new line.");

//Send attachment file
//upload a test file as attachment first
var uploadInfo=await bot.Upload("./libgrpc_csharp_ext.x64.so");
if (uploadInfo!=null)
{
    //then build a attachment message with attchment success
    responseMsg = MsgBuilder.BuildAttachmentMessage(uploadInfo, "This is a larget attachment file");
}

build your chatbot,a complete example:

class Program
    {
        public class CmdOptions
        {
            [Option('C', "login-cookie", Required = false, Default = ".tn-cookie", HelpText = "read credentials from the provided cookie file")]
            public string CookieFile { get; set; }
            [Option('T', "login-token", Required = false, HelpText = "login using token authentication")]
            public string Token { get; set; }
            [Option('B', "login-basic", Required = false, HelpText = "login using basic authentication username:password")]
            public string Basic { get; set; }
            [Option('L', "listen", Required = false, Default = "0.0.0.0:40051", HelpText = "address to listen on for incoming Plugin API calls")]
            public string Listen { get; set; }
            [Option('S', "server", Required = false, Default = "localhost:16060", HelpText = "address of Tinode server gRPC endpoint")]
            public string Host { get; set; }
        }
