plus.push.addEventListener 方法下执行uni.switchTab跳转操作提示路径错误

plus.push.addEventListener("click", function(msg) {    
                                    console.log("click:"+JSON.stringify(msg));    
                                    // console.log("payload: "+msg.payload);    
                                    console.log(JSON.stringify(msg));   
                                    // handlePushR(msg);  
                                    uni.switchTab({  
                                        url:'pages/main/main'  
                                    })                                
                                }, false);  
```点击报错  switchTab:fail page `/pages/login/pages/main/main` is not found    
为什么我 switchTab 放的路径是 'pages/main/main' 但是 跳转的会是 `/pages/login/pages/main/main`   
如果我把跳转方法放到 addEventListener 监听事件外面 能够正常跳转，pages/login是所在界面的目录  
求解答
