错误：无法在“窗口”上执行“atob”：要解码的字符串未正确编码

Question

这是我的 Javascript 代码

function upload(){
var byteCharacters = atob($scope.image1.compressed.dataURL.replace(/^data:image\(png|jpg);base64,/,''));
var byteNumbers = new Array(byteCharacters.length);
         for (var i = 0; i < byteCharacters.length; i++) {
          byteNumbers[i] = byteCharacters.charCodeAt(i);
         }
var byteArray = new Uint8Array(byteNumbers);
 var blob = new Blob([ byteArray ], {
     type : undefined
   });

这是我的 HTML

<div class="form-group text-16px" style="margin-top: 20px !important;">
    <label>Choose Material Photo : </label>
    <div>
    <input id="materialImage" type="file" accept="image/*" image="image1" resize-max-height="800" resize-max-width="800" resize-quality="0.7" resize-type="image/jpg" file-model="file" name="materialImage" onChange="checkFile()" ng-image-compress/>
    <div id="choose-image-compresser">
      <div image="image1" result-image="myCompressedImage"></div>
      </div>
    <img ng-src="{{image1.compressed.dataURL}}" />
        <span id="image-size-error" style="color:red;" hidden=""><small>Image size is too large</small></span>
    </div>
</div>

我遇到错误

Error: Failed to execute 'atob' on 'Window': 要解码的字符串 编码不正确

Answer 1

我遇到了问题。它应该有助于其他用户保存图像并使用 javascript(AnguarJs) 压缩图像。

我正在流此链接以压缩图像 Github

https://github.com/oukan/angular-image-compress

var imageData = $scope.image1.compressed.dataURL.toString();
var byteCharacters = atob(imageData.replace(/^data:image\/(png|jpeg|jpg);base64,/, ''));
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {
  byteNumbers[i] = byteCharacters.charCodeAt(i);
}

var byteArray = new Uint8Array(byteNumbers);
var blob = new Blob([ byteArray ], {
   type : undefined
});

检查您的代码后，您似乎有可能不支持的字符。 Check screenshot 如果这不起作用，请确保您尝试上传的文件的名称已编码为您的数据库或设置支持的名称。

这是没有这些字符的代码：

var byteCharacters = atob($scope.image1.compressed.dataURL.replace(/^data:image\/(png|jpg);base64,/,'')); var byteNumbers = new Array(byteCharacters.length);
