问题描述
我有个formpanel, 里面有个FileUploadField，选择一个文件后，传到struts2的Action中，但是从调试的显示中看到参数没有传过去，响应的结果为null. 我想请大家帮我看看代码怎么改，多谢了 MyDesktop.ScriptWindow = Ext.extend(Ext.app.Module, { id:'script-win', init : function(){ this.launcher = { text: 'Script Selection', iconCls:'tabs', handler : this.createWindow, scope: this } }, createWindow : function(){ var desktop = this.app.getDesktop(); var win = desktop.getWindow('script-win'); if(!win){ win = desktop.createWindow({ id: 'script-win', title:'Script Selection', width:400, height:450, iconCls: 'tabs', shim:false, animCollapse:false, border:false, constrainHeader:true, layout: 'fit', items: new Ext.FormPanel({ id:'script', labelWidth: 70, frame:true, bodyStyle:'padding:5px 5px 0', width: 350, items: [{ xtype:'fieldset', title: 'Script Load', collapsible: true, autoHeight:true, defaults: {width: 210}, defaultType: 'textfield', items :[new Ext.ux.form.FileUploadField({ id: 'upload', name: 'upload', emptyText: '', fieldLabel: 'Script', allowBlank:false, buttonText: '', buttonCfg: { iconCls: 'tabs' } }), new Ext.form.ComboBox({ id: 'mobile', name:'mobile', triggerAction:'all', fieldLabel: 'Phone', store: store, displayField: 'imsi', valueField: 'ip', mode:'local', allowBlank:false, emptyText: 'Select a phone' }) ], buttons: [{ type: 'submit', text: 'Associate', handler:function(){ //Ext.Msg.alert("success", Ext.getCmp('upload').getValue()); if(Ext.getCmp('script').getForm().isValid()){ Ext.getCmp('script').getForm().doAction("submit",{ url:"scriptLoad.action", method:"post", success:function(form,action){ Ext.Msg.alert("Success",action.result.message); }, failure:function(form, action){ Ext.Msg.alert("Failer",action.result.message); } }) } } },{ text: 'Cancel', handler: function(){ Ext.getCmp('upload').reset(); Ext.getCmp('mobile').reset(); } }] }, { xtype:'fieldset', title: 'Script View', collapsible: true, height:250, labelWidth: 2, items : new Ext.form.TextArea({ xtype:'textarea', name: 'script', anchor: '100% 100%', disabled: true, value:'loop->1:100, CALL -> <TO_BE_DEFINED>:5, SLEEP -> 2000, END LOOP -> ID=1' }) }] }) }); } win.show(); }}); LoadScriptAction.javapublic class LoadScriptAction extends ActionSupport{ private File upload; private String uploadContentType; private String uploadFileName; private String mobile; private String message; public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } public File getUpload() { return upload; } public void setUpload(File upload) { this.upload = upload; } public String getUploadContentType() { return uploadContentType; } public void setUploadContentType(String uploadContentType) { this.uploadContentType = uploadContentType; } public String getUploadFileName() { return uploadFileName; } public void setUploadFileName(String uploadFileName) { this.uploadFileName = uploadFileName; } public String getMobile() { return mobile; } public void setMobile(String mobile) { this.mobile = mobile; } public String execute() throws Exception{ message = this.uploadFileName + " " + this.mobile; return SUCCESS; }}<struts> <include file="struts-default.xml"/> <package name="script" extends="json-default"> <action name="scriptLoad" class="android.action.LoadScriptAction"> <result type="json"/> </action> </package> </struts> 调试显示： (我要传两个参数过去，一个是我选择的文件，一个是mobile的号码。为什么这里只显示传了一个参数过去？） 参数application/x-www-form-urlencoded
解决方案
你用application/x-www-form-urlencoded传输FileUpload文件上传时肯定不行啊，你得设置 multipart/form-data, 这样不论是文本还是文件都可以的，不过在Ext中怎么设置成multipart/form-data 你自己找一下。
解决方案二：
upload = Ext.extend(Ext.Window,{ title : '批量导入', width : 350, height : 80, autoHeight : true, modal : true, collapsible : true, frame : true, resizable : false, buttonAlign : 'center', initComponent : function(){ Ext.apply(this,{ items : [{ xtype : 'form', id : 'form', labelWidth : 70, labelAlign : 'right', border : false, fileUpload : true, baseCls : 'x-plain', bodyStyle : 'padding : 5px 5px 0', defaults : { anchor : '100%', magTarget : 'side' }, items : [{xtype : 'textfield',inputType : 'file',name:'upload',fieldLabel : '文件上传'}] }] }); upload.superclass.initComponent.apply(this,arguments); }});

解决方案四：
不懂。。。。是不是因为默认的参数类型是text，所以文件没上传上去items: [{ xtype:'fieldset', title: 'Script Load', collapsible: true, autoHeight:true, defaults: {width: 210}, defaultType: 'textfield',
