ueditor搭建图片服务器
最近用使用富文本编辑器，之前一直使用kindeditor和eWebEditor来着，有同事给推荐说使用百度推出的Ueditor，所以咯，自己新项目就将它引进来了，这里说一下心得，
说实话，Ueditor的官网文档真的一般，但是还是能让人看懂的，只不过有些地方写法实在操蛋。不过简单的上手还是很容易的，好了，废话不多说，直接上干货。
一、简单的使用

<script type="text/javascript">
var ue;
// 初始化函数
$(document).ready(function() {
mini.parse();
ue = UE.getEditor('container', {
serverUrl: "${ctx}/system/authority/getImgServer.ac",
toolbars: [
[
'bold', //加粗
'indent', //首行缩进
'snapscreen', //截图
'italic', //斜体
'underline', //下划线
'strikethrough', //删除线
'fontborder', //字符边框
'formatmatch', //格式刷
'source', //源代码
'horizontal', //分隔线
'removeformat', //清除格式
'insertcode', //代码语言
'fontfamily', //字体
'fontsize', //字号
'selectall', //全选
'print', //打印
'preview', //预览
'paragraph', //段落格式
'horizontal', //分隔线
'simpleupload', //单图上传
'insertimage', //多图上传
'removeformat', //清除格式
'date', //日期
'time', //时间

'emotion', //表情
'spechars', //特殊字符

'justifyleft', //居左对齐
'justifyright', //居右对齐
'justifycenter', //居中对齐
'justifyjustify', //两端对齐
'forecolor', //字体颜色
'backcolor', //背景色
'insertorderedlist', //有序列表
'insertunorderedlist', //无序列表
'fullscreen', //全屏
'imagecenter', //居中
'lineheight', //行间距
'edittip ', //编辑提示
'customstyle', //自定义标题
'touppercase', //字母大写
'tolowercase', //字母小写
'autotypeset', //自动排版
]
],
autoHeightEnabled: true,
autoFloatEnabled: true
}); }); </script>
</head>
<body> <script id="container" name="describes" type="text/plain" style="width:100%;height:350px;"></script> </body>
</html>
简单功能实现
通过代码片段可以看到
<script id="container" name="describes" type="text/plain" style="width:100%;height:350px;"></script>
这句话中 name的名字为describes 那么表单提交的话，提交到后台，只需要获取这个describes参数就可以拿到前台传递到后台的富文本内容了，
如果项目是使用struts2的框架的话，则只需要再后台的action中写一个叫describes的属性，富文本内容就被自动注入到这个属性中了。
ok，拿到前台提交过来的值后，就不需要我在说了吧，各种增删改查还不是随自己的心意去写咯。
二、搭建图片服务器后台
在上述代码中可以看到，在初始化编辑器的时候有这么一句话
serverUrl: "${ctx}/system/authority/getImgServer.ac",
这句话是重写了它验证后台是否符合他的要求的路径。
默认他会调用jsp/controller.jsp这个路径
我这里贴一下我后台处理的代码

验证后台是否符合要求需要返回的json格式
其中action为uploadimage时表示图片上传，这个可以改写，上面的验证时的返回的json其实就是对下面操作的设置，但是有一点比较恶心的是貌似就几个字段设置管用其他
例如图片路径啥的都不管用，这里图片上传也需要返回一个json
我从官网示例中测出来的json格式：http://ueditor.baidu.com/server/ueditor/controller.php?action=uploadimage
{"original":"demo.jpg","name":"demo.jpg","url":"\/server\/ueditor\/upload\/image\/demo.jpg","size":"99697","type":".jpg","state":"SUCCESS"}
上传图片返回的json格式
其中action为listimage表示图片管理，这个也可以改写，和上面图片上传一样
我从官网示例中测数来的json格式：http://ueditor.baidu.com/server/ueditor/controller.php?action=config&&noCache=1467768503808
{"imageActionName":"uploadimage","imageFieldName":"upfile","imageMaxSize":2048000,"imageAllowFiles":[".png",".jpg",".jpeg",".gif",".bmp"],"imageCompressEnable":true,"imageCompressBorder":1600,"imageInsertAlign":"none","imageUrlPrefix":"","imagePathFormat":"\/server\/ueditor\/upload\/image\/{yyyy}{mm}{dd}\/{time}{rand:6}","scrawlActionName":"uploadscrawl","scrawlFieldName":"upfile","scrawlPathFormat":"\/server\/ueditor\/upload\/image\/{yyyy}{mm}{dd}\/{time}{rand:6}","scrawlMaxSize":2048000,"scrawlUrlPrefix":"","scrawlInsertAlign":"none","snapscreenActionName":"uploadimage","snapscreenPathFormat":"\/server\/ueditor\/upload\/image\/{yyyy}{mm}{dd}\/{time}{rand:6}","snapscreenUrlPrefix":"","snapscreenInsertAlign":"none","catcherLocalDomain":["127.0.0.1","localhost","img.baidu.com"],"catcherActionName":"catchimage","catcherFieldName":"source","catcherPathFormat":"\/server\/ueditor\/upload\/image\/{yyyy}{mm}{dd}\/{time}{rand:6}","catcherUrlPrefix":"","catcherMaxSize":2048000,"catcherAllowFiles":[".png",".jpg",".jpeg",".gif",".bmp"],"videoActionName":"uploadvideo","videoFieldName":"upfile","videoPathFormat":"\/server\/ueditor\/upload\/video\/{yyyy}{mm}{dd}\/{time}{rand:6}","videoUrlPrefix":"","videoMaxSize":102400000,"videoAllowFiles":[".flv",".swf",".mkv",".avi",".rm",".rmvb",".mpeg",".mpg",".ogg",".ogv",".mov",".wmv",".mp4",".webm",".mp3",".wav",".mid"],"fileActionName":"uploadfile","fileFieldName":"upfile","filePathFormat":"\/server\/ueditor\/upload\/file\/{yyyy}{mm}{dd}\/{time}{rand:6}","fileUrlPrefix":"","fileMaxSize":51200000,"fileAllowFiles":[".png",".jpg",".jpeg",".gif",".bmp",".flv",".swf",".mkv",".avi",".rm",".rmvb",".mpeg",".mpg",".ogg",".ogv",".mov",".wmv",".mp4",".webm",".mp3",".wav",".mid",".rar",".zip",".tar",".gz",".7z",".bz2",".cab",".iso",".doc",".docx",".xls",".xlsx",".ppt",".pptx",".pdf",".txt",".md",".xml"],"imageManagerActionName":"listimage","imageManagerListPath":"\/server\/ueditor\/upload\/image\/","imageManagerListSize":20,"imageManagerUrlPrefix":"","imageManagerInsertAlign":"none","imageManagerAllowFiles":[".png",".jpg",".jpeg",".gif",".bmp"],"fileManagerActionName":"listfile","fileManagerListPath":"\/server\/ueditor\/upload\/file\/","fileManagerUrlPrefix":"","fileManagerListSize":20,"fileManagerAllowFiles":[".png",".jpg",".jpeg",".gif",".bmp",".flv",".swf",".mkv",".avi",".rm",".rmvb",".mpeg",".mpg",".ogg",".ogv",".mov",".wmv",".mp4",".webm",".mp3",".wav",".mid",".rar",".zip",".tar",".gz",".7z",".bz2",".cab",".iso",".doc",".docx",".xls",".xlsx",".ppt",".pptx",".pdf",".txt",".md",".xml"]}
图片管理返回的json格式
目前来讲项目中只需要实现图片的功能，例如音频视频也可以设置，返回的json格式大家可以自己去官网检测一下，总体来说功能还是不错的，比较容易上手，但是官网的api实在太一般。
最后还有一点要值得注意的是：它自己有初始化的方法，和jquery的初始化方法加载的时间顺序不太一样，最好用他自己的初始化，例如我想在一个页面一加载完就禁用掉不让用户编辑
那么直接使用它自己提供的初始化数据后的事件即可，
var ue;
// 初始化函数
$(document).ready(function() {
mini.parse();
ue = UE.getEditor('container', {
serverUrl: "${ctx}/system/authority/getImgServer.ac",
toolbars: [
["fullscreen"]
],
autoHeightEnabled: true,
autoFloatEnabled: true
});
ue.addListener( 'ready', function( editor ) {
ue.setDisabled("fullscreen"); //编辑器加载完成后，禁用编辑器 } ); });
初始化时禁用编辑器脚本
