如何在 Angular 5 Tiny MCE 组件中处理图像上传？

Question

我在 Angular 5 项目中使用 TinyMCE 编辑器，并且想要处理图像上传，但我目前无法做到这一点。这是我当前的代码：

<editor 
  name="questionStatement" 
  apiKey="somekey" 
  [init]='{
    plugins : [
        "advlist autolink lists link image charmap print preview hr anchor pagebreak",
        "searchreplace wordcount visualblocks visualchars code fullscreen",
        "insertdatetime media nonbreaking save table contextmenu directionality",
        "emoticons template paste textcolor colorpicker textpattern"
      ],
      toolbar1: "insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image", 
      past_date_images: true,
      external_plugins: { tiny_mce_wiris: "https://www.wiris.net/demo/plugins/tiny_mce/plugin.js" },
      toolbar: "tiny_mce_wiris_formulaEditor, tiny_mce_wiris_formulaEditorChemistry"
    }'
  </editor>

我正在遵循此代码示例https://codepen.io/nirajmchauhan/pen/EjQLpV 来处理图像上传。我不明白，如何将file_picker_callback函数传递给角度编辑器？

还有其他方法吗，我应该如何处理图片上传？

我尝试阅读文档，但找不到任何内容。我已经被这个问题困扰很长时间了，如果有人能够帮助我解决这个问题，那就太好了。

这对我有用（我正在使用@tinymce/tinymce-angular）：

<editor [(ngModel)]="source" [init]="tinymceInit"></editor>

在构造函数或初始化中：

...

this.tinymceInit = {
  plugins : [
    "advlist autolink lists link image charmap print preview hr anchor pagebreak",
    "searchreplace wordcount visualblocks visualchars code fullscreen",
    "insertdatetime media nonbreaking save table contextmenu directionality",
    "emoticons template paste textcolor colorpicker textpattern"
  ],
  toolbar : 'formatselect | bold italic strikethrough forecolor backcolor | link | alignleft aligncenter alignright alignjustify  | numlist bullist outdent indent  | removeformat',
  image_advtab : true,
  file_picker_callback : function(cb, value, meta) {
    var input = document.createElement('input');
    input.setAttribute('type', 'file');
    input.setAttribute('accept', 'image/*');

    // Note: In modern browsers input[type="file"] is functional without 
    // even adding it to the DOM, but that might not be the case in some older
    // or quirky browsers like IE, so you might want to add it to the DOM
    // just in case, and visually hide it. And do not forget do remove it
    // once you do not need it anymore.

    input.onchange = function() {
      var file = input.files[0];

      var reader = new FileReader();
      reader.onload = function () {
        // Note: Now we need to register the blob in TinyMCEs image blob
        // registry. In the next release this part hopefully won't be
        // necessary, as we are looking to handle it internally.
        var id = 'blobid' + (new Date()).getTime();
        var blobCache =  tinymce.activeEditor.editorUpload.blobCache;
        var base64 = reader.result.split(',')[1];
        var blobInfo = blobCache.create(id, file, base64);
        blobCache.add(blobInfo);

        // call the callback and populate the Title field with the file name
        cb(blobInfo.blobUri(), { title: file.name });
      };
      reader.readAsDataURL(file);
    };

    input.click();
  }
}

编辑：要添加，您也可以使用该功能来上传文件，如您所知。我更愿意拥有我正在从事的特定项目的 base64 数据。
