推荐答案

可以通过转换为Blob来完成

it can be done by using conversion to Blob

dataURItoBlob(dataURI) {
    var binary = atob(dataURI.split(',')[1]);
    var array = [];
  for (var i = 0; i < binary.length; i++) {
     array.push(binary.charCodeAt(i));
  }
 return new Blob([new Uint8Array(array)], {
    type: 'image/jpg'
});
}

    enter code here

 var myFile:Blob=this.dataURItoBlob(myDataUri);
