vue.js - VueJS CKeditor5上传图片

Question

在Vuejs中使用CKeditor5上传图像时遇到麻烦。
首先尝试过Simple upload Adapter，这给了我以下错误:

Reason: CKEditorError: ckeditor-duplicated-modules: Some CKEditor 5 modules are duplicated. Read more: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-ckeditor-duplicated-modules

我尝试制作一个上传适配器。作为上载适配器，我接受了 example并修改了网址。 uploadadapter.js文件如下所示:

export default class UploadAdapter {
    constructor( loader ) {
        // The file loader instance to use during the upload.
        this.loader = loader;
    }

    // Starts the upload process.
    upload() {
        return this.loader.file
            .then( file => new Promise( ( resolve, reject ) => {
                this._initRequest();
                this._initListeners( resolve, reject, file );
                this._sendRequest( file );
            } ) );
    }

    // Aborts the upload process.
    abort() {
        if ( this.xhr ) {
            this.xhr.abort();
        }
    }

    // Initializes the XMLHttpRequest object using the URL passed to the constructor.
    _initRequest() {
        const xhr = this.xhr = new XMLHttpRequest();

        xhr.open( 'POST', '<url here>', true );
        xhr.responseType = 'json';
    }

    // Initializes XMLHttpRequest listeners.
    _initListeners( resolve, reject, file ) {
        const xhr = this.xhr;
        const loader = this.loader;
        const genericErrorText = `Couldn't upload file: ${ file.name }.`;

        xhr.addEventListener( 'error', () => reject( genericErrorText ) );
        xhr.addEventListener( 'abort', () => reject() );
        xhr.addEventListener( 'load', () => {
            const response = xhr.response;

            if ( !response || response.error ) {
                return reject( response && response.error ? response.error.message : genericErrorText );
            }

            resolve( {
                default: response.url
            } );
        } );

        if ( xhr.upload ) {
            xhr.upload.addEventListener( 'progress', evt => {
                if ( evt.lengthComputable ) {
                    loader.uploadTotal = evt.total;
                    loader.uploaded = evt.loaded;
                }
            } );
        }
    }

    // Prepares the data and sends the request.
    _sendRequest( file ) {
        // Prepare the form data.
        const data = new FormData();

        data.append( 'upload', file );

        // Send the request.
        this.xhr.send( data );
    }
}

Vue组件:

<template>
    <form @submit.prevent="store">
        <ckeditor
            :editor="editor"
            v-model="form.content"
            :error-messages="errors.content"
            :config="editorConfig"
        />
    </form>
</template>

<script>
    import CKEditor from '@ckeditor/ckeditor5-vue';
    import ClassicEditor from '@ckeditor/ckeditor5-build-classic';
    import UploadAdapter from '../../UploadAdapter';

    export default {
        data()
        {
            return {
                form: {
                    content: null,
                },
                editor: ClassicEditor,
                editorConfig: {
                    toolbar: [ 'heading', '|', 'bold', 'italic', 'link', 'bulletedList', 'numberedList', '|', 'insertTable', '|', 'imageUpload', 'mediaEmbed', '|', 'undo', 'redo' ],
                    table: {
                        toolbar: [ 'tableColumn', 'tableRow', 'mergeTableCells' ]
                    },
                    extraPlugin: [this.uploader],
                    language: 'nl',
                },
            }
        },

        methods: {
            store()
            {
                // Some code
            },

            uploader(editor)
            {
                editor.plugins.get( 'FileRepository' ).createUploadAdapter = ( loader ) => {
                    return new UploadAdapter( loader );
                };
            },
        },

        components: {
            ckeditor: CKEditor.component
        }
    }
</script>

但是，每次尝试上传文件时，都会返回以下警告:

filerepository-no-upload-adapter: Upload adapter is not defined. Read more: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-filerepository-no-upload-adapter

看过网址，但它只是圈出了我，因此没有任何进展。我正在寻找的是一个示例，该示例至少将文件发送到服务器而没有错误/警告。如果uploadadapter可以是 抓取的，并且可以使用除CKfinder之外的其他东西，那就很好了。现在，我想问题很可能出在Vue组件中。

使用extraPlugins而不是extraPlugin。
