net core建站

net core建站踩坑记录

系统：win10
VS版本：2017
.NET Core 版本： 1.1

零.读取配置文件

参考：http://www.tuicool.com/articles/QfYVBvi

1. 此版本无需添加其他组件
2. 在appsettings.json配置中添加节点AppSettings
   
3. 添加配置文件的映射模型
   

4. 在Startup.cs ConfigureServices方法中注册
   

       services.AddOptions();
       services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));

5. Controller中使用
   

一、登录记录session

参考：http://www.cnblogs.com/fonour/p/5943401.html

二、发布.net core1.1.2网站到windos服务器

参考：https://docs.microsoft.com/en-us/aspnet/core/publishing/iis

1. 我的服务器是windows server 2012 ,.net core网站版本为1.1.2
2. 经安装好iis
3. 下载安装：
   .NET Core Windows Server Hosting
   Microsoft Visual C++ 2015 Redistributable Update 3
   
4. 发布.net core网站到IIS，并将应用池的.NET CLR版本修改为[无托管代码]
   

三、DES加密解密算法

亲测可用

  public class SecurityHelper
  {
      #region 加密解密法一
      //默认密钥向量 
      private static byte[] Keys = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F };
      /// <summary> 
      /// DES加密字符串 
      /// </summary> 
      /// <param name="encryptString">待加密的字符串</param> 
      /// <param name="encryptKey">加密密钥,要求为16位</param> 
      /// <returns>加密成功返回加密后的字符串，失败返回源串</returns> 
      public static string EncryptDES(string encryptString, string encryptKey = "Key123Ace#321Key")
      {
          try
          {
              byte[] rgbKey = Encoding.UTF8.GetBytes(encryptKey.Substring(0, 16));
              byte[] rgbIV = Keys;
              byte[] inputByteArray = Encoding.UTF8.GetBytes(encryptString);
              var DCSP = Aes.Create();
              MemoryStream mStream = new MemoryStream();
              CryptoStream cStream = new CryptoStream(mStream, DCSP.CreateEncryptor(rgbKey, rgbIV), CryptoStreamMode.Write);
              cStream.Write(inputByteArray, 0, inputByteArray.Length);
              cStream.FlushFinalBlock();
              return Convert.ToBase64String(mStream.ToArray());
          }
          catch (Exception ex)
          {
              return ex.Message + encryptString;
          }
      }
      /// <summary> 
      /// DES解密字符串 
      /// </summary> 
      /// <param name="decryptString">待解密的字符串</param> 
      /// <param name="decryptKey">解密密钥,要求为16位,和加密密钥相同</param> 
      /// <returns>解密成功返回解密后的字符串，失败返源串</returns> 
      public static string DecryptDES(string decryptString, string decryptKey = "Key123Ace#321Key")
      {
          try
          {
              byte[] rgbKey = Encoding.UTF8.GetBytes(decryptKey.Substring(0, 16));
              byte[] rgbIV = Keys;
              byte[] inputByteArray = Convert.FromBase64String(decryptString);
              var DCSP = Aes.Create();
              MemoryStream mStream = new MemoryStream();
              CryptoStream cStream = new CryptoStream(mStream, DCSP.CreateDecryptor(rgbKey, rgbIV), CryptoStreamMode.Write);
              Byte[] inputByteArrays = new byte[inputByteArray.Length];
              cStream.Write(inputByteArray, 0, inputByteArray.Length);
              cStream.FlushFinalBlock();
              return Encoding.UTF8.GetString(mStream.ToArray());
          }
          catch (Exception ex)
          {
              return ex.Message + decryptString;
          }
      }
      #endregion 
  }

四、过滤器定义

继承Attribute,实现IActionFilter即可
简单校验登录,获取cookie值并解密后得到用户名,未登录则跳转登录(ApplicationKey为自定义的类存放)

public class UserCheckFilterAttribute : Attribute, IActionFilter
{
    public void OnActionExecuted(ActionExecutedContext context)
    {
    }
    public void OnActionExecuting(ActionExecutingContext filterContext)
    {
        string encryptValue = "";
        filterContext.HttpContext.Request.Cookies.TryGetValue(ApplicationKey.User_Cookie_Key, out encryptValue);
        if (encryptValue == null)
        {
            filterContext.Result = new RedirectResult("/Account/Login");
            return;
        }
        var userName = SecurityHelper.DecryptDES(encryptValue, ApplicationKey.User_Cookie_Encryption_Key);
        if (string.IsNullOrEmpty(userName))
        {
            filterContext.Result = new RedirectResult("/Account/Login");
            return;
        }
    }
}

五、注入服务

Startup.cs中的ConfigureServices方法调用services.AddTransient<IUserService,UserService>();注册服务

待解决问题

根据路径调用脚本
