APP使用 webview组件 就可以收到H5的message消息。换做plus.webview.create创建的就接受不到message

let headers = {  
                    "Access-Control-Allow-Origin" :"*",  
                    "Access-Control-Allow-Headers":"*",  
                    "Access-Control-Allow-Methods":"POST, GET, OPTIONS, DELETE, PUT",  
                    "Access-Control-Allow-Credentials":"true"  
                };  
                //创建webview  
                let topheight = plus.navigator.getStatusbarHeight() + 45  
                const webview = plus.webview.create('http://10.8.191.152:10020/robot/index', '', {  
                    progress: {  
                        color: '#FF3333'  
                    },  
                    top: topheight+'px',  
                    bottom: "1px",  
                    additionalHttpHeaders: headers,  
                });
