uniapp 开发微信小程序 使用 workers

需要在pages.json里面添加"workers": "workers",
manifest.json里面添加 "workers": "workers"，

      var worker = wx.createWorker('workers/wk-1.js')  
      worker.onMessage((res) => {  
        console.log("主线程接收到的",res)  
      })  
      worker.postMessage({  
        msg: 'hello from main'  
      }) 

      worker.onMessage(function (res) {  
              console.log("worker 接收到 ",res)  
              worker.postMessage({  
                msg: '返回 hello worker'  
              })  
      })
