tinymce与Laravel图片上传

最近在做Laravel中集成tinymce编辑器，选择tinymce的原因是因为对表格等方面的支持比较方便一些。
但是遇到了图片上传的难题，用了若干天来想办法，甚至想过用axios代替xhr，不过最后还是用xhr解决了问题。
下面贴一下代码：

<script>
    tinymce.init({
        selector: '#content',
        height: 800,
        plugins: [
            'advlist autolink link image lists charmap preview hr anchor ',
            'searchreplace wordcount visualblocks visualchars code fullscreen media ',
            'save table directionality template paste'
        ],
        toolbar1: "bold italic underline strikethrough | alignleft aligncenter alignright alignjustify | forecolor backcolor | outdent indent blockquote | bullist numlist ",
        toolbar2: "formatselect | link unlink anchor image media | table | hr removeformat | subscript superscript | charmap preview code searchreplace",
        images_upload_handler: function (blobInfo, success, failure) {
            var xhr, formData;
            xhr = new XMLHttpRequest();
            xhr.withCredentials = false;
            xhr.open('POST', '{{route("image.upload")}}');
            var token = '{{ csrf_token() }}';
            xhr.setRequestHeader("X-CSRF-Token", token);
            xhr.onload = function() {
                var json;
                if (xhr.status != 200) {
                    failure('HTTP Error: ' + xhr.status);
                    return;
                }
                json = JSON.parse(xhr.responseText);

                if (!json || typeof json.location != 'string') {
                    failure('Invalid JSON: ' + xhr.responseText);
                    return;
                }
                success(json.location);
            };
            formData = new FormData();
            formData.append('file', blobInfo.blob(), blobInfo.filename());
            xhr.send(formData);
        },
        menubar: false,
        toolbar_items_size: 'small',
        language: 'zh_CN',
    });

这里面的重点就是要设置csrf。
