SharePoint【学习笔记】--【Sandbox Solution】-- Full Trust Proxy --开发实例之(1、创建一个能访问DataBase的Full Trust Proxy)

SharePoint【学习笔记】--【Sandbox Solution】-- Full Trust Proxy--开发步骤一文,我们讲述了开发和部署Sandbox Solution的Full Trust Proxy的基本步骤,在这里,我们采用另一种方式来开发和部署一个能访问数据库的Full Trust Proxy,由于内容比较多,所以分割成两个部分,本部分主要讲如何开发这个Full Trust Proxy,而下一部分则讲如何在Webpart中调用它来展示所取得的数据库数据。

  直接进入操作步骤。

一、创建和设置项目
1、在Vs2010中新建一个Empty SharePoint Project,命名为: MyTestSandBoxAccessDBInfo,由于是开发Full Trust Proxy,所以此项目要基于Farm开发,

我们用于测试的Sharpoint网站网址是 http://sd1-sp1dev:5000/sites/Develop/

2、在Solution Explorer中,选择项目名并点击鼠标右键,在弹出菜单中选择Properties,从而打开项目设置窗口
  2.1在此窗口中选择Application栏,设置Default namespace和Assembly name两项,分别为My.Sharepoint.SandBox.MyTestSandBoxAccessDBInfo和My.Sharepoint.SandBox,如下图
  

SharePoint【学习笔记】--【Sandbox Solution】-- Full Trust Proxy --开发实例之(1、创建一个能访问DataBase的Full Trust Proxy)_第3张图片
 2.2在此窗口中选择Sharepoint栏,设置Post-deployment CommandLine内容:

  net stop SPUsercodeV4
  net start SPUsercodeV4

  它的主要目的是保证我们在每一次修改此full trust proxy并形成和发布其新的版本时,自动重新启动Microsoft SharePoint Foundation Sandboxed Code service,以使新的改动在Sharepoint网站中生效。

 3、在Solution Explorer中,双击并打开Assembly.info,在此文件底部加入

  [assembly: AllowPartiallyTrustedCallers]

 二、创建Full Trust Proxy 相关类
在项目中添加一个新的目录TestProxyCode,我们将在此目录下添加我们的Full Trust Proxy相关类。

1、创建数据库访问类:在目录TestProxyCode添加一个新类,命名为SQLDBAccess.cs,此类的代码如下:

View Code
using System;
using System.Data;
using System.Data.SqlClient;

namespace My.Sharepoint.SandBox.MyTestSandBoxAccessDBInfo.TestProxyCode
{
    
/// <summary>
    
/// 通用数据库类 SQLDBAccess
    
/// </summary>
    public class SQLDBAccess
    {
        
private string ConnStr = null;
        
private const int TIME_OUT = 180;

        
#region connected flag
        
//connected is a flag to make sure if have connect to Database
        
//when exception happed, perhaps close connect mannual is better
        private bool connected = false;

        
#endregion

        
#region 构造函数
        
public SQLDBAccess()
        {
            
//ConnStr = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["MySQL"].ToString();
            ConnStr = "Data Source=serverDB;Initial Catalog=MyDb;User ID=MyApp;Password=mypwd";
        }

        
public SQLDBAccess(string Str)
        {
            
try
            {
                ConnStr 
= Str;

            }
            
catch (Exception ex)
            {
                
throw ex;
            }
        }

        
#endregion

        
#region 公用函数

        
#region   返回connection对象
        
/// <summary>
        
/// 返回connection对象
        
/// </summary>
        
/// <returns></returns>
        public SqlConnection ReturnConn()
        {
            SqlConnection Conn 
= new SqlConnection(ConnStr);
            Conn.Open();
            
return Conn;
        }
        
#endregion

        
#region 释放connection对象
        
public void Dispose(SqlConnection Conn)
        {
            
if (Conn != null)
            {
                Conn.Close();
                Conn.Dispose();
            }
            GC.Collect();
        }
        
#endregion

        
#endregion

        
#region 运行SQL语句相关

        
#region  运行SQL语句,返回DataSet对象 --SQL, Ds
        
/// <summary>
        
/// 运行SQL语句,返回DataSet对象
        
/// </summary>
        
/// <param name="procName">SQL语句</param>
        
/// <param name="prams">DataSet对象</param>
        public DataSet RunProc(string SQL, DataSet Ds)
        {
            SqlConnection Conn;
            Conn 
= new SqlConnection(ConnStr);
            Conn.Open();
            SqlDataAdapter Da;
            
//Da = CreateDa(SQL, Conn);
            Da = new SqlDataAdapter(SQL, Conn);
            
try
            {
                Da.Fill(Ds);
            }
            
catch (Exception Err)
            {
                
throw Err;
            }
            Dispose(Conn);
            
return Ds;
        }

        
#endregion

        
#endregion

    
    }
}

 

2、创建Full trust proxy的Operation类:在目录TestProxyCode添加一个新类,命名为SQLProxyExecute.cs,此类的代码如下:

View Code
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
using Microsoft.SharePoint.UserCode;
using System.Data;

namespace My.Sharepoint.SandBox.MyTestSandBoxAccessDBInfo.TestProxyCode
{
   
   [Microsoft.SharePoint.Security.SharePointPermission(System.Security.Permissions.SecurityAction.LinkDemand, ObjectModel 
= true)]
   
public  class SQLProxyExecute : SPProxyOperation
    {
        
public override object Execute(SPProxyOperationArgs args)
        {
            
if (args != null)
            {
                SQLProxyArgs ftArgs 
= args as SQLProxyArgs;
                SQLDBAccess dba 
= new SQLDBAccess(ftArgs.connectionString);
                DataSet ds 
= new DataSet();
                
return dba.RunProc(ftArgs.sqlCommand, ds);
            }
            
else return null;
        }
    }
}


3、创建Full trust proxy的Argument参数类:在目录TestProxyCode添加一个新类,命名为SQLProxyArgs.cs,此类的代码如下:

View Code
using System;
using Microsoft.SharePoint.UserCode;


namespace My.Sharepoint.SandBox.MyTestSandBoxAccessDBInfo.TestProxyCode
{
    [Serializable]
    [Microsoft.SharePoint.Security.SharePointPermission(System.Security.Permissions.SecurityAction.LinkDemand, ObjectModel 
= true)] 
    
public class SQLProxyArgs : SPProxyOperationArgs
    {
        
public string connectionString { getset; }
        
public string sqlCommand { getset; }

        
public SQLProxyArgs(string ConnectionString, string SqlCommand)
        {
            
this.connectionString = ConnectionString;
            
this.sqlCommand = SqlCommand;
        }
    }
}

  

 三、注册Full Trust Proxy到sandboxed code service
 1、在Solution Explorer中,右击Feature目录,选择添加新Feature.

 2、右击Feature1目录,选择重命名,重命名为:Registration,如下图

 3、双击Registration.feature,打开其设置窗口,设置它的Title和DescriptSharePoint【学习笔记】--【Sandbox Solution】-- Full Trust Proxy --开发实例之(1、创建一个能访问DataBase的Full Trust Proxy)_第7张图片ion。
 


 4、右击Registration,添加一个Event Receiver

 5、修改此Event Receiver的后台代码如下:

View Code
using System;
using System.Runtime.InteropServices;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Security;

using Microsoft.SharePoint.UserCode;
using Microsoft.SharePoint.Administration;

namespace My.Sharepoint.SandBox.MyTestSandBoxAccessDBInfo.Features.Registration
{
    
/// <summary>
    
/// This class handles events raised during feature activation, deactivation, installation, uninstallation, and upgrade.
    
/// </summary>
    
/// <remarks>
    
/// The GUID attached to this class may be used during packaging and should not be modified.
    
/// </remarks>

    [Guid(
"f64dd849-567d-497a-bd56-9e92ea33f9ce")]
    
public class RegistrationEventReceiver : SPFeatureReceiver
    {
        
// Uncomment the method below to handle the event raised after a feature has been activated.

        
public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            Type type 
= typeof(My.Sharepoint.SandBox.MyTestSandBoxAccessDBInfo.TestProxyCode.SQLProxyExecute);
            SPProxyOperationType proxyOperationType 
= new SPProxyOperationType(type.Assembly.FullName, type.FullName);
            SPUserCodeService userCodeService 
= SPUserCodeService.Local;
            userCodeService.ProxyOperationTypes.Add(proxyOperationType);
            userCodeService.Update();

        }
        
// Uncomment the method below to handle the event raised before a feature is deactivated.
        public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
        {
            Type type 
= typeof(My.Sharepoint.SandBox.MyTestSandBoxAccessDBInfo.TestProxyCode.SQLProxyExecute);
            SPProxyOperationType proxyOperationType 
= new SPProxyOperationType(type.Assembly.FullName, type.FullName);
            SPUserCodeService userCodeService 
= SPUserCodeService.Local;
            userCodeService.ProxyOperationTypes.Remove(proxyOperationType);
            userCodeService.Update();

        }


        
// Uncomment the method below to handle the event raised after a feature has been installed.

        
//public override void FeatureInstalled(SPFeatureReceiverProperties properties)
        
//{
        
//}


        
// Uncomment the method below to handle the event raised before a feature is uninstalled.

        
//public override void FeatureUninstalling(SPFeatureReceiverProperties properties)
        
//{
        
//}

        
// Uncomment the method below to handle the event raised when a feature is upgrading.

        
//public override void FeatureUpgrading(SPFeatureReceiverProperties properties, string upgradeActionName, System.Collections.Generic.IDictionary<string, string> parameters)
        
//{
        
//}
    }
}
