android - cordova/phonegap 图像上传到 Amazon s3

Question

我正在尝试将图像(作为 base64 格式)从电话间隙应用程序上传到 amazon s3。图片上传成功，但是当我尝试在亚马逊服务器中查看图片时，它显示为方框。我使用以下链接作为引用。

Uploading image to S3 using phonegap, how to?

我还尝试使用下面的链接上传图片(作为 imageURI)，但它会抛出错误 Body.params is required

请找到代码 fragment ，

// take picture
var options =   {
          quality: 75,
          targetWidth: 320,
          targetHeight: 320,
          destinationType: 1, // 0 = base 64, 1 = imageURI
          sourceType: 1,      // 0:Photo Library, 1=Camera, 2=Saved Photo Album
          encodingType: 0     // 0=JPG 1=PNG
      };
    // Take picture using device camera and retrieve image as base64-encoded string
    navigator.camera.getPicture(onSuccess,onFail,options);


    ---------
uploading the image

var imageData = 'data:image/jpeg;base64,'+ $scope.lastPhoto;
         var params = {
              Key: 'test5.jpg', // for testing purpose 
              Body: imageData, // base64 data
              ContentEncoding: 'base64',
              ContentType: 'image/jpeg'
            };
            var fileName = "" + (new Date()).getTime() + ".jpg"; 
            console.log ('data params' + params.Body);
            bucket.upload(params, function(err, data){
              $scope.hide($ionicLoading);
              var result = err ? 'ERROR!' : 'UPLOADED SUCCESSFULLY...';
              var alertPopup = $ionicPopup.alert({
                 title: 'Amazon  Confirmation',
                 template: 'Result : ' + result
              });

你能查看这个链接吗 how to save canvas data to file

var data = img.replace(/^data:image/\w+;base64,/, "");
