课程简介

创建一个接受消息的机器人

通过本教程，你将学会如何用 C# 创建一个机器人APP,让它能接受消息.

C# 安装:

下载安装最新的 .Net Core SDK .

macOS

下载双击安装包然后安装.

Ubuntu

打开终端然后按下面的流程安装

wget -q https://packages.microsoft.com/config/ubuntu/16.04/packages-microsoft-prod.debsudo dpkg -i packages-microsoft-prod.debsudo apt-get install apt-transport-httpssudo apt-get updatesudo apt-get install dotnet-sdk-2.2复制代码

执行一下 dotnet --version 检查是不是安装好了！

$ dotnet --version2.2.104复制代码

创建 C# 目录

创建 C# 目录, 比如: echo_bot, 再执行 dotnet new console 创建一个终端下的应用程序! macOS

mkdir echo_botcd echo_botdotnet new console复制代码

执行输出内容如下：

root@ubuntu:~/echo_bot# dotnet new consoleGetting ready...The template "Console Application" was created successfully.Processing post-creation actions...Running 'dotnet restore' on /root/echo_bot/echo_bot.csproj...  Restoring packages for /root/echo_bot/echo_bot.csproj...  Generating MSBuild file /root/echo_bot/obj/echo_bot.csproj.nuget.g.props.

你好, 世界

现在我们已经创建了一个“你好世界”的程序，编译然后运行!

安装 Mixin Network SDK for C#

本教程的程序代码依赖 Mixin CSharp SDK, 可以使用dotnet来安装此包。

$ dotnet add package MixinCSharpSdk复制代码

创建第一个机器人APP

按下面的提示，到创建一个APP.

生成相应的参数

记下这些 config.cs中.

config.cs,将生成的参数，替换成你的！

config.cs

namespace echo_bot{    static class USRCONFIG    {        public static string ClientId = "21042518-85c7-4903-bb19-f311813d1f51";        public static string ClientSecret = "f14ccf35e52b7e888c2f5a2081bacbed93cb998a1d4e4ab353856a9d3a8beed9";        public static string PinCode = "911424";        public static string SessionId = "4267b63d-3daa-449e-bc13-970aa0357776";        public static string PinToken = "gUUxpm3fPRVkKZNwA/gk10SHHDtR8LmxO+N6KbsZ/jymmwwVitUHKgLbk1NISdN8jBvsYJgF/5hbkxNnCJER5XAZ0Y35gsAxBOgcFN8otsV6F0FAm5TnWN8YYCqeFnXYJnqmI30IXJTAgMhliLj7iZsvyY/3htaHUUuN5pQ5F5s=";        public static string PrivateKey =        @"-----BEGIN RSA PRIVATE KEY-----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-----END RSA PRIVATE KEY-----";    }}复制代码

Program.cs 的代码如下:

     (message);            System.Console.WriteLine("incomingMessage");            if ( (incomingMessage.action == "CREATE_MESSAGE") && (incomingMessage.data != null) ) {                Console.WriteLine(incomingMessage.data.conversation_id);                MixinApi callback = (MixinApi)sender;                //send ack for every Create Message!                callback.SendMessageResponse(incomingMessage.data.message_id).Wait();                if (incomingMessage.data.category == "PLAIN_TEXT") {                  byte[] strOriginal = Convert.FromBase64String(incomingMessage.data.data);                  string clearText = System.Text.Encoding.UTF8.GetString(strOriginal);                  Console.WriteLine(clearText);                  callback.SendTextMessage(incomingMessage.data.conversation_id, clearText).Wait();                }            }            Console.WriteLine(incomingMessage);            if (incomingMessage.action == "ACKNOWLEDGE_MESSAGE_RECEIPT")            {                System.Console.WriteLine("This message has read already: " + incomingMessage.data.message_id);            }            if (incomingMessage.action == "LIST_PENDING_MESSAGES")            {                System.Console.WriteLine("The bot is listening!");            }        }    }}复制代码

编译并运行

执行 dotnet build 将产生一个 echo_bot.dll 文件, 执行方法如下.

dotnet builddotnet bin/Debug/netcoreapp2.2/echo_bot.dllroot@ubuntu:~/echo_bot# dotnet bin/Debug/netcoreapp2.2/echo_bot.dllincomingMessage{
   "id":"e1ad0301-57ee-4c80-8695-09648f732c8b","action":"LIST_PENDING_MESSAGES","data":null}The bot is listening!复制代码

在手机安装 ,增加机器人为好友,(比如这个机器人是7000101639) 然后发送消息给它,效果如下!

源代码解释

初始化 Mixin API

MixinApi mixinApi = new MixinApi();  mixinApi.Init(USRCONFIG.ClientId, USRCONFIG.ClientSecret,                USRCONFIG.SessionId, USRCONFIG.PinToken,                USRCONFIG.PrivateKey);复制代码

WebSocket是建立在TCP基础之上的全双工通讯方式，连接到Mixin Network并发送"LISTPENDINGMESSAGES"消息，服务器以后会将收到的消息转发给此程序!

mixinApi.WebSocketConnect(HandleOnRecivedMessage).Wait();  mixinApi.StartRecive();复制代码

当服务器给机器人推送消息的时候,机器人会原封不动的回复回去.

if ( (incomingMessage.action == "CREATE_MESSAGE") && (incomingMessage.data != null) ) {    Console.WriteLine(incomingMessage.data.conversation_id);    MixinApi callback = (MixinApi)sender;    //send ack for every Create Message!    callback.SendMessageResponse(incomingMessage.data.message_id).Wait();    if (incomingMessage.data.category == "PLAIN_TEXT") {      byte[] strOriginal = Convert.FromBase64String(incomingMessage.data.data);      string clearText = System.Text.Encoding.UTF8.GetString(strOriginal);      Console.WriteLine(clearText);      callback.SendTextMessage(incomingMessage.data.conversation_id, clearText).Wait();    }}复制代码

Mixin Messenger支持的消息类型很多，除了文本，还有图片，视频，语音等等，具体可到下面链接查看: .

完成

现在你的机器人APP运行起来了，你打算如何改造你的机器人呢？
