使用北京点聚信息技术有限公司的WebOffice工具上传文件

在北京点聚信息技术有限公司的SDK文档中关于文件上传有下面这一段话：

因为Web页面上的WebOffice打开的文件无法随表单记录提交到处理页面，所以我们把文件模拟成表单的文件域<input type=file …>，通过接口把文件和表单元素发送到保存记录的页面（过程类似表单的提交）。

上面这段意思无非就是不能用提交表单的方式上传文件，因为weboffice打开的文件没有在表单里面。但是它自己做了一个接口用来解决这个问题。

         //
添加上传文件
         document.all.WebOffice1.HttpAddPostCurrFile("AipFile ","");  
       用来对当前页面在weboffice里面打开的文件进行上传提交，效果与提交表单是一样的。

/****************************************************
*                                            上传文档
*****************************************************/
function SaveDoc(id,docType) {
         try{
                  
var webObj=document.getElementById("WebOffice1");
                  
var returnValue;
                  
webObj.HttpInit();                          //初始化Http引擎
                  
// 添加相应的Post元素
                  
webObj.HttpAddPostString("id", id);
                  
webObj.HttpAddPostString("DocType",docType);
                  
webObj.HttpAddPostCurrFile("DocContent","");               //
上传文件
                  
returnValue = webObj.HttpPost("/TestUploadAction");      //
判断上传是否成功
                  
if("succeed" == returnValue){
                           alert("文件上传成功");        
                  
}else if("failed" == returnValue)
                           alert("文件上传失败");
                  
//return_onclick();
         }catch(e){
                  
alert("异常\r\nError:"+e+"\r\nError Code:"+e.number+"\r\nError Des:"+e.description);
         }
}
         这段代码的效果跟下面这段代码的效果是一样的，只不过下面代码中file只能是指定路径上传，而在上面的代码中是在页面中嵌入的doc可以直接上传到服务器，不管是否已经保存到本地。

       <form action="TestUploadAction" name="myform" id="myform">
                  
<input type="text" name="id"/>
                  
<input type="text" name="DocType">
                  
<input type="file" name="DocContent">
         </form>
         <script type="text/javascript">
                  
myform.submit();
         </script>
         Struts里面配置Action

       <action name="TestUploadAction" class="TestUploadAction" method="Function">
         </action>
       Spring配置Bean

<bean id="TestUploadAction" class="test.TestUploadAction">
                  
<property name="fs" ref="FileService"></property>
         </bean>
         <!--
文件管理service的Bean -->
         <bean id="FileService" class="net.ib.util.service.impl.FileServiceImpl">
         </bean>

       在点聚信息技术有限公司提供的示例程序里面，在接收端是用jsp写的，里面调用了SmartUpload这个对象以及其方法，在这里我们用Struts框架中的Action代替掉了jsp文件，并且脱离了SmartUpload初始化时需要获取pageContext这个对象的烦恼。提供了了Weboffice向服务器传输文件的功能。

前端编辑文件，并且点击提交上传

在服务器端收到该文件并另存为test.doc
