    园子里有同学介绍 BeetleX.FastHttpApi  组件,可以在 应用程序或服务中 搭建 web 服务 ,看起来挺强大的 。 通过 html +  css + js  做为应用程序UI ,winform 做为后端,完美替代 WPF + WCF。 搭建要点如下:

 

1. BeetleX.FastHttpApi  通过 Nuget 包管理器获取。 其宿主环境需运行在 .net framework 4.6.1 以上版本。

2. 官方示例下载地址:

      https://github.com/IKende/FastHttpApi/tree/master/samples/WinWebSample

       控制器示例下载地址:

       https://github.com/IKende/FastHttpApi/tree/master/samples/HttpApiServer.HttpAndWebsocketApi

       https://github.com/IKende/FastHttpApi/blob/master/Extend/BeetleX.FastHttpApi.Admin/AdminController.cs

       

3.web 服务器默认将 views 文件夹做为 root 目录 , 通过 HttpOptions.StaticResourcePath 参数值调整 root 路径 ,也可通过 HttpApiServer.Debug 调整该参数。

4.BeetleX.FastHttpApi  启动时,会将包含 Controller 属性类都做为控制器方法 , 通过 BaseUrl 指定 调用方法路径。

控置器与前端脚本交互示例:

[Controller(BaseUrl = "course/")]
public class WebAction
{

    public object GetStarted(string email)
    {
        return new TextResult($"{email} {DateTime.Now}");
    }
    
    [NotAction]
    public void Init(BeetleX.FastHttpApi.HttpApiServer server,string path)
    {
        mServer = server;
    }

    [Post]
    public bool EditEmployee(int id,Employee emp, IHttpContext context)
    {
        Employee record = mEmployees.Find(e => e.EmployeeID == id);
        if (record != null)
        {
            record.City = emp.City; 
            record.Address = emp.Address;
            record.Title = emp.Title;
            record.HomePhone = emp.HomePhone;
            return true;
        }
        return false;
    }    
}

 

前端调用:

function GetStarted(email) {
            $.get('/course/GetStarted?email=' + email, function (result) {
                alert(result);
            });
        }

 

Controller 类,设置 SingleInstance 可配置为单例模式 , BaseUrl 设定路由地址。

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Interface)]
    public class ControllerAttribute : Attribute
    {
        public string BaseUrl
        {
            get;
            set;
        }

        public bool SingleInstance
        {
            get;
            set;
        }

        public ControllerAttribute()
        {
            SingleInstance = true;
        }
    }

 

5. 在 winform 中 通过 WebBrower 访问Web 服务,可通过如下方法设置IE 版本,否则默认 WebBrower 版本是 IE7 。

private void SetIE()
        {
            int BrowserVer, RegVal;
            BrowserVer = webBrowser1.Version.Major;
            if (BrowserVer >= 11)
                RegVal = 11001;
            else if (BrowserVer == 10)
                RegVal = 10001;
            else if (BrowserVer == 9)
                RegVal = 9999;
            else if (BrowserVer == 8)
                RegVal = 8888;
            else
                RegVal = 7000;
            string productName = AppDomain.CurrentDomain.SetupInformation.ApplicationName;//获取程序名称
            RegistryKey key = Registry.CurrentUser;
            RegistryKey software =
                key.CreateSubKey(
                    @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION\" + productName);
            if (software != null)
            {
                software.Close();
                software.Dispose();
            }
            RegistryKey wwui =
                key.OpenSubKey(
                    @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);
            if (wwui != null) wwui.SetValue(productName, RegVal, RegistryValueKind.DWord);
            webBrowser1.Url = new Uri("http://192.168.1.178:12345");
        }

 

6.在应用程序根目录 添加 HttpConfig.json做为 服务初使化配置,注意 通过 Host 可限制网络访问权限。

{
  "HttpConfig": {
    "Host": "0.0.0.0",
    "Port": 12345,
    "SSL": false,
    "CertificateFile": "",
    "CertificatePassword": "",
    "MaxBodyLength": 20097152,
    "OutputStackTrace": true,
    "StaticResurceType": "xml;svg;woff;woff2;jpg;jpeg;gif;png;js;html;htm;css;txt;ico;zip;rar",
    "DefaultPage": "index.html;index.htm",
    "NotLoadFolder": "\\Files;\\Images;\\Data",
    "NoGzipFiles": "xml;svg;woff;woff2;jpg;jpeg;gif;png;js;html;htm;css;txt;ico;zip;rar",
    "CacheFiles": "",
    "BufferSize": 8192,
    "WebSocketMaxRPS": 2000,
    "WriteLog": true,
    "LogToConsole": true,
    "LogLevel": "Warring"
  }
}

 

7.  BeetleX.FastHttpApi 服务与 Winform(宿主) 交互,如关闭窗体,控制 winform 控件等  ,  这里有几种思路:

1.可以通过消息中间件(MQ)实现 

2.通过c# 自带事件实现,如:

/// <summary>
    /// 全局静态资源类
    /// </summary>
    public class UIResource {

        System.Windows.Forms.Control control;

        public event EventHandler EventHanderForm;

        public UIResource(System.Windows.Forms.Control control) {
            this.control = control;
        }

        /// <summary>
        /// 关闭窗口
        /// </summary>
        public void ActionForm() {
            if (EventHanderForm != null) {
                if (control.InvokeRequired)
                {
                    control.Invoke(new Action(() =>
                    {
                        EventHanderForm(null, null);
                    }));
                }
                else
                {
                    EventHanderForm(null, null);
                }
            }
        }

    }
static UIResource uiResource;
public Form1()
{
    InitializeComponent();

    if (uiResource == null)
    {
        uiResource = new UIResource(this);
        uiResource.EventHanderForm += UiResource_eventHander;
    }
}

private void UiResource_eventHander(object sender, EventArgs e)
{
    //隐藏主窗体
    formCursor.Hide();

    //弹出新窗体
    Form1 f = new Form1();
    f.Show();
}

[Controller(BaseUrl = "course/")]
public class WebAction
{
    public object GetStarted(string email)
    {

        //触发事件
        uiResource.ActionForm();
        return new TextResult($"{email} {DateTime.Now}");
    }
}

 

3.宿主资源静态化,通过 Invoke 实现。

[Controller(BaseUrl = "course/")]
        public class WebAction
        {
            public object GetStarted(string email)
            {
                formCursor.Invoke(new Action(() =>
                {
                    //隐藏主窗体
                    formCursor.Hide();

                    //弹出新窗体
                    Form1 f = new Form1();
                    f.Show();
                }));
                
                return new TextResult($"{email} {DateTime.Now}");
            }
        }
