editormd 上传图片问题解决

    看这个就够了!
    http://editor.md.ipandao.com/examples/

    一、下载源码

    首先在 editormd 官方下载源码:

    删除 test、examples、docs 无用文件夹,重命名文件夹如下:

    二、移入源码到项目

    这里,我把 plugins 文件夹单独拎出来了。根据需要调整文件位置,只要 js css 文件在浏览器链接中可以访问到就行。

    在 IDEA 中右键 editormd、plugins 两个文件夹 ,Marked directory as Exclusion,这样两个文件夹下的文件就可以在浏览器访问了。

    三、thymeleaf 页面引用

    test.html:

    <!DOCTYPE html>
    <html lang="zh" xmlns:th="http://www.thymeleaf.org">
    <head>
        <meta charset="utf-8" />
    
        <title>测试文档</title>
    
        <link rel="shortcut icon" href="favicon.ico">
    
        // 注意,thymeleaf 下,引用需要加 th: @{}
        <link rel="stylesheet" th:href="@{/css/style.css}" />
        <link rel="stylesheet" th:href="@{/css/editormd.css}" />
    
        <script th:inline="javascript">
            var testEditor;
            /*提交表单的js*/
            function contentCommit(comments){
    
                var docType = "3";
                var documentId = "123";
                var documentName = "测试文档";
    
                var mdContent = $('#content').val();
    
                var content = {
                    documentType:docType,
                    documentId:documentId,

                    },
    
                    /*给自定义按钮指定回调函数*/
                    toolbarHandlers:{
                        releaseIcon : function(cm, icon, cursor, selection) {
                            // contentCommit();//提交表单代码在下面

                            $('#test-editormd .editormd-preview-close-btn').hide()
                        }else {
                            $('#test-editormd [name="preview"]').click();

                    }
                });
    
                // 对escape()编码的字符串进行解码
                function getQueryString(name) {
                    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "I");
                    var r = window.location.search.substr(1).match(reg);
                    if(r != null){
                        return unescape(r[2]);
                    }
                    return null;//如果此处只写return;则返回的是undefined
                };
    
    
            }
        </script>
    </head>
    <body>
    <div id="layout">
        <header>
            <h1>更新验证规范</h1>
        </header>
    
        <form name="mdEditorForm" target="_blank">

                <textarea name="content" id="content" style="display:none;" class="textArea"> </textarea>

        </form>
    
    </div>
    <script th:src="@{/js/jquery.min.js}"></script>
    
    // 注意,thymeleaf 下,引用需要加 th: @{}
    <script th:src="@{/editormd/editormd.min.js}"></script>

    </body>
    </html>
    
    四、controller 后端接口
    @Controller
    public class MdImageUploadController {
    
        @Autowired
        private ServerConfig serverConfig;
    
        @RequestMapping(value = "/markdown/uploadImageFile", method = RequestMethod.POST)
        @ResponseBody
        public String uploadFile(HttpServletRequest request, HttpServletResponse response,
                                     @RequestParam(value = "editormd-image-file", required = false) MultipartFile attach){
    
            JSONObject jsonObject=new JSONObject();
            if (!attach.isEmpty())
            {
                try {
                    String imgUrl = MdFileUploadUtils.upload(Global.getMarkdownImagesPath(), attach);
    
                    String url = serverConfig.getUrl() + imgUrl;
    
                    jsonObject.put("success", 1);
                    jsonObject.put("message", "上传成功");
                    jsonObject.put("url", url);
                } catch (Exception e) {
                    jsonObject.put("success", 0);
                }
            }
            jsonObject.put("success", 0);
            jsonObject.put("message", "上传图片异常,请联系管理员");
            return jsonObject.toString();
        }
    }
    

    图片上传成功后,返回 json 字符串,前端 js 不需要回调处理,但是 json 字符串一定要按照如下格式。

    Editor.md 期待的返回:

    {
      'success(1表示成功,0表示失败)': 1(或0),
      'message': 'message',
      'url(如果失败则不返回)': 'imageURL'
    }
    
    五、上传图片成功后回调

    调试中,遇到问题,图片上传成功后,没能在输入框展示图片链接,修改了 js 文件后,问题解决。

    上传成功后:

    六、md 编辑页面工具类按钮

    可以根据自己需要,自定义功能按钮:

    /**下述为新增,上面一行记得加逗号结束*/
    /*指定需要显示的功能按钮*/
    toolbarIcons : function() {
        return ["undo", "redo", "|","bold", "italic","ucwords","uppercase","lowercase","|","h1","h2","h3","h4","h5","h6","|","list-ul","list-ol","table","image","datetime","hr",  "||",  "watch", "fullscreen", "preview", "releaseIcon", "selectHistoryIcon","help"]
        // return editormd.toolbarModes['simple']; // full, simple, mini
    },
    
    full:["undo","redo","|","bold","del","italic","quote","ucwords","uppercase","lowercase","|","h1","h2","h3","h4","h5","h6","|","list-ul","list-ol","hr","|","link","reference-link","image","code","preformatted-text","code-block","table","datetime","emoji","html-entities","pagebreak","|","goto-line","watch","preview","fullscreen","clear","search","|","help","info"],
    simple:["undo","redo","|","bold","del","italic","quote","uppercase","lowercase","|","h1","h2","h3","h4","h5","h6","|","list-ul","list-ol","hr","|","watch","preview","fullscreen","|","help","info"],
    mini:["undo","redo","|","watch","preview","|","help","info"]
