Topic: MDB - FileUpload Plugin - Support for blob and base64 string
Expected behavior
When assigning a base64 or blob url to the [defaultFile] attribute I expect to see the preview of the image.
Actual behavior
No image is shown, the blob and base64 string is removed/ignored and console shows:
ERROR TypeError: url.split is not a function at MdbFileUploadComponent._cleanFileName (mdb-file-upload.js:217) at MdbFileUploadComponent._setDefaultPreview (mdb-file-upload.js:124) at MdbFileUploadComponent.set defaultFile [as defaultFile] (mdb-file-upload.js:116)
Resources (screenshots, code snippets etc.)
<mdb-file-upload #uploader [defaultFile]="image"></mdb-file-upload>
this.http.get(environment.graphUrl + 'v1.0/me/photo/$value', { responseType: 'blob' })
.subscribe(blobImage => {
const objectURL = URL.createObjectURL(blobImage);
this.image = this.sanitizer.bypassSecurityTrustUrl(objectURL);
},
Final URL: "blob:http://localhost:4200/65d8ef50-98b9-4824-9b90-bdecf877d5e1"This is also happening with base64 strings or images returned by an api that don't have a file ending (for example http://myapi.com/getPicture/23) won't work while (http://myapi.com/getPicture/23.jpg) is working fine.
The name of input can be a bit confusing in this case, but it's not possible to use an actual javascript file object as a default file added to the HTML file input. It is just a default preview image displayed in the component drop zone.

I want to use a simple image (in my opinion a safeurl and a base64 string are no javascript objects) but both are not displayed in the drop zone.

The [defaultFile] accepts only image src that is directly passed to the src tag of the element inside the drop zone. It is expected behavior in this case.
