小程序ArrayBuffer转JSON

      let arrayBuffer = fsm.readFileSync(res.tempFilePath)
      let unit8Arr = new Uint8Array(arrayBuffer)
      let encodedString = String.fromCharCode.apply(null, unit8Arr)
      let decodedString = decodeURIComponent(escape(encodedString))
      console.log(JSON.parse(decodedString))

 

let arrayBuffer = fsm.readFileSync(tempFilePath,"utf-8")
console.log(JSON.parse(arrayBuffer))
