iso上传的时候返回值总是{"exception":"No JSON web service action associated with path ..."}

问个上传的问题，同样的接口，代码，安卓手机上上传都OK，iso上传的时候返回值总是{"exception":"No JSON web service action associated with path /igimage/addImage and method POST for /"} ，会是哪出的问题。

相关代码如下：

function upload_img(){  
                    if(files_img==""){  
                        console.log("图片没有变更,无需重新上传");  
                        upload_files();  
                        return;  
                    }  
                    var server=host + "/api/secure/jsonws/igimage/addImage";  
                    console.log("开始上传图片：")  
                    var wt=plus.nativeUI.showWaiting("图片上传中...");  

                    var task=plus.uploader.createUpload(server,  
                        {method:"POST"},  
                        function(t,status){ //上传完成  
                            if(status==200){  
                                console.log("图片上传成功"+t.responseText);  
                                image_id = (JSON.parse(t.responseText)).imageId;  
                                wt.close();  
                                upload_files();   
                            }else{  
                                                                console.log("图片上传失败"+status);  
                                wt.close();  
                                plus.nativeUI.alert("图片上传失败！");  
                            }     
                        }  
                    );  
                    var path=files_img;  
                    var fname = path.substr(path.lastIndexOf("/") + 1,path.length);  
                    console.log('fpath:===='+ path);  
                    console.log('fname:===='+ fname);  

                    task.addData("folderId","17002");  
                    task.addData("name",fname);  
                    task.addData("description","event_img");  
                    task.addFile(path,{key:"file"});  
                    task.addData("contentType","jpg");  
                    task.addData("serviceContext","{}");  
                    task.addData("tagsCategories","");  
                    task.addData("tagsEntries","");  

                    task.start();                     
                }
