概述
通常JavaScript在Web浏览器执行展现特定效果，C#也可以后台执行JavaScript里面方法；C#通常调用第三方DLL方式：MsieJavaScriptEngine或者JavaScriptEngineSwitcher。具体使用列举如下；
MsieJavaScriptEngine使用
Nuget里面，添加MsieJavaScriptEngine的类库；由于MsieJavaScriptEngine不支持.NET Core下Linux的部署运行，代码使用方式如下：
public static string Ck3(string cert, string ts, string nullPara, string page, string token)
{
var basePath = AppDomain.CurrentDomain.BaseDirectory;
using (var jsEngine = new MsieJsEngine())
{
jsEngine.ExecuteFile(string.Format(@"{0}/Scripts/myscript.js", basePath));
string[] arr = new string[] { cert, ts, nullPara, page, token };
jsEngine.Execute("var $CFMethod=$.ck;");
var publickey = jsEngine.CallFunction("$CFMethod", arr);
return publickey.ToString();
}
}
JavaScriptEngineSwitcher的使用
Nuget里面，添加JavaScriptEngineSwitcher的类库；由于JavaScriptEngineSwitcher支持.NET Core下Linux和Win的部署运行，另外还需要安装的类库
JavaScriptEngineSwitcher.ChakraCore.Native.linux-x64 ///针对Linux-x64环境下组件；
JavaScriptEngineSwitcher.ChakraCore.Native.win-x64 //针对Wind-x64环境下组件；
JavaScriptEngineSwitcher.ChakraCore.Native.win-x32 //针对Wind-x32环境下组件；
代码使用方式如下：
public static string Ck(string cert, string ts, string nullPara, string page, string token)
{
var basePath = AppDomain.CurrentDomain.BaseDirectory;
IJsEngineSwitcher engineSwitcher = JsEngineSwitcher.Current;
engineSwitcher.EngineFactories.Add(new ChakraCoreJsEngineFactory());
engineSwitcher.DefaultEngineName = ChakraCoreJsEngine.EngineName;
using (IJsEngine engine = JsEngineSwitcher.Current.CreateDefaultEngine())
{
engine.ExecuteFile(string.Format(@"{0}/Scripts/myscipt.js", basePath));
string[] arr = new string[] { cert, ts, nullPara, page, token };
engine.Execute("var $CFMethod=$.ck;");
var publickey = engine.CallFunction("$CFMethod", arr);
return publickey.ToString();
}
}
