如何将DOM发送到服务器中的Image (Vuejs)？

Question

请任何人能告诉我如何发送Base64图像到服务器，我正在使用Dom的图像库。

//My script
    import domtoimage from "dom-to-image";
        export default {data: function() {return{ post: { image: "" },}
           createPost(post) {
                 var node = document.getElementById("my-node");
                  domtoimage.toPng(node).then(function(dataUrl) {
                  var image = new Image();
                  image.src = dataUrl;
                  document.body.appendChild(image); }) this.$store.dispatch('createPost', post)},}

    //In Action.js
createPost({commit}, post) {axios.post('posts', post).then(res => {commit('CREATE_POST', res.data)})},

   imgProfile(event) {
       this.image = event.target;
        if (this.image.files && this.image.files[0]) {
            var reader = new FileReader();
            reader.onload = (e) => {
                this.imageData = e.target.result;
            }
            reader.readAsDataURL(this.image.files[0]);
            this.SvImage = this.image.files[0];
        }

    },
