Update SPListItem using Web Service

这几天为了在SharePoint上集成发短信的功能,忙得不可开交。短信猫的驱动程序Mondem.dll在64跨平台调用的时候出现封装如下:

public    class   CmonDem 
    
{
        
            
//初始化
        [DllImport("mondem.dll", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
            
public static extern int fnInitModem(int nPortNo);
           
//得到短信猫的类型
        [DllImport("mondem.dll", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
            
public static extern int fnSetModemType(int ComNo,int modemType);


            
//发送
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnSendMsg (int nPortNo,  string  szPhone,  string  szMsg);
            
//目标手机号码+序列号+已发送次数   例如:  138123456789,001,0

            
//接收
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnReadMsgEx (int nPortNo,    StringBuilder  szHeader,    StringBuilder  szReadMsg);
         
            
//关闭
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnCloseModem (int nPortNo);

            
//得到软件最大支持端口号
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnGetPortMax();

            
//获取端口状态函数 
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnGetStatus(int nPortNo);

            
//取发送缓冲区条数
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnGetSndCount (int nPortNo);

            
//取接收缓冲区条数
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnGetRecCount (int nPortNo);

            
//清除发送缓冲区
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnClrSndBuf (int nPortNo);

            
//清除接收缓冲区
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnClrRecBuf (int nPortNo);


            
//检测软件狗存在
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnDogCheck ();

            [DllImport(
"mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnDogSerial();

            
//读取软件狗信息
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnDogRead (int bufLen,  string  szBuf);
   
            
//写软件狗信息
            [DllImport("mondem.dll", CharSet=CharSet.Ansi)]
            
public static extern int fnDogWrite (int bufLen, string  szBuf);

            [DllImport(
"kernel32.dll")]
            
public static extern int GetTickCount();
            

     

        }

但是初始化的时候出现如下错误:

System.BadImageFormatException was unhandled
  Message

  Source

查了好久的资料,才弄明天原来是编译的时候出问题了,Mondem.dll驱动是在32位机器上编译的,但是我的程序是编译成64位的,所以平台调用的时候就出错误了,
因此需要选择X86的目标机器编译才不会有问题,具体设置如下图所示: 

可事情还没完,选择X86的程序后,此程序却访问不了SharePoint 站点了,代码片断如下:

  using  (SPSite site  =   new  SPSite( " http://www.test.com " ))
                  
{
                      
using (SPWeb targetWeb = site.AllWebs[""])
                      
{
                          site.AllowUnsafeUpdates 
= true;
                          targetWeb.AllowUnsafeUpdates 
= true;

                          
                         

                         
                          targetWeb.AllowUnsafeUpdates 
= false;
                          site.AllowUnsafeUpdates 
= false;
                      }

                  }

初始化SPSite的时候就出现异常,异常信息如下:

System.IO.FileNotFoundException was unhandled
  Message
= " 找不到位于 http://www.test.com 的 Web 应用程序。请确认正确键入了此 URL。如果此 URL 需要提供现有内容,则系统管理员可能需要添加到指定应用程序的新请求 URL 映射。 "
  Source

  StackTrace:

莫名其妙,但是可以肯定地是由于编译平台X86的原因,于是此路不通,只得在SharPoint里面调用Web Service对列表字段进行操作,也深刻的体会到了Web Service的妙处,同时意识到平时自己做的Web Service是多么的不规范,调用,或者发布Web Service,都只能使用XML,这才是通用的,否则就失去意义,通过Web Service 对SharePoint 列表的操作代码如下,里面有详细的注释,应该没什么问题

   /*初始化 Web service.*/
            com.test.www.Lists listService 
=   new  com.test.www.Lists();

            
/*认证*/
            listService.Credentials 
=
                System.Net.CredentialCache.DefaultCredentials;



            
/*设置Web Service的Url属性.*/
            listService.Url 
=
                
" http://www.test.com/_vti_bin/Lists.asmx " ;

            
/*使用XML 传递参数*/
            System.Xml.XmlDocument doc 
=   new  System.Xml.XmlDocument();
            System.Xml.XmlElement batchElement 
=  doc.CreateElement( " Batch " );
            batchElement.SetAttribute(
" OnError " " Continue " );
            batchElement.SetAttribute(
" ListVersion " " 1 " );
            
/*需要操作视图的GUID*/
            batchElement.SetAttribute(
" 所有项目 " ,
                
" {38c8fdc3-4259-4d82-a2b5-d907d11a5a7c} " ); /*GUID*/

            
/*这段CAML需要填写正确,Web Service调用的就是根据它执行相应操作,CAML语法还是挺强大的,
             * 微软不知道用了多少人研究出来,它可以处理各种逻辑关系
*/

            batchElement.InnerXml 
=   " <Method ID='1' Cmd='Update'> "   + // 此ID是Method的执行顺序
                                     " <Field Name='ID'>6</Field> "   +   // 此ID是SPListItem的ID,更新或者删除的时候才有用
                                     " <Field Name='Title'>sixth</Field></Method> "   +   // 需要更新的字段及其值
                                     " <Method ID='2' Cmd='New'> "   + // 此ID是Method的执行顺序
                                     " <Field Name='ID'>7</Field> "   + // 此ID是SPListItem的ID,新建的时候此值无效,可以不填
                                     " <Field Name='Title'>seventh</Field></Method> " ; // 新建时字段的值

            
// Update list items.
            listService.UpdateListItems( " Test " , batchElement);

到此,问题基本上解决了
