在python web.py中使用百度富文本编辑器 UEditor

UEditor官方没有支持python的版本,有人改了个python的django版本,但是没找到web.py的。

于是参考php版本,实现了一下web.py集成UEditor,包含了文件上传,图片上传,视频上传,图片远程抓取,涂鸦等。

可能会有一些session之类的没有处理。

Demo代码可以在https://github.com/meizhitu/100programhomework/tree/master/100-25-literal-10-todo 查看

首先改ueditor.config.js,把原来指向php的链接改成web.py的

 //图片上传配置区
        ,imageUrl:"/ue_imageUp"             //图片上传提交地址
        ,imagePath:""                     //图片修正地址,引用了fixedImagePath,如有特殊需求,可自行配置
        //,imageFieldName:"upfile"                  //图片数据的key,若此处修改,需要在后台对应文件修改对应参数
        //,compressSide:0                           //等比压缩的基准,确定maxImageSideLength参数的参照对象。0为按照最长边,1为按照宽度,2为按照高度
        //,maxImageSideLength:900                   //上传图片最大允许的边长,超过会自动等比缩放,不缩放就设置一个比较大的值,更多设置在image.html中
        //,savePath: [ 'upload1', 'upload2', 'upload3' ]    //图片保存在服务器端的目录, 默认为空, 此时在上传图片时会向服务器请求保存图片的目录列表,
                                                            // 如果用户不希望发送请求, 则可以在这里设置与服务器端能够对应上的目录名称列表
                                                            //比如: savePath: [ 'upload1', 'upload2' ]

        //涂鸦图片配置区
        ,scrawlUrl:"/ue_scrawlUp"           //涂鸦上传地址
        ,scrawlPath:""                            //图片修正地址,同imagePath

        //附件上传配置区
        ,fileUrl:"/ue_fileUp"               //附件上传提交地址
        ,filePath:""                   //附件修正地址,同imagePath
        //,fileFieldName:"upfile"                    //附件提交的表单名,若此处修改,需要在后台对应文件修改对应参数

        //远程抓取配置区
        //,catchRemoteImageEnable:true               //是否开启远程图片抓取,默认开启
        ,catcherUrl:"/ue_getRemoteImage"   //处理远程图片抓取的地址
        ,catcherPath:""                  //图片修正地址,同imagePath
        //,catchFieldName:"upfile"                   //提交到后台远程图片uri合集,若此处修改,需要在后台对应文件修改对应参数
        //,separater:'ue_separate_ue'               //提交至后台的远程图片地址字符串分隔符
        //,localDomain:[]                            //本地顶级域名,当开启远程图片抓取时,除此之外的所有其它域名下的图片都将被抓取到本地,默认不抓取127.0.0.1和localhost

        //图片在线管理配置区
        ,imageManagerUrl:"/ue_imageManager"       //图片在线管理的处理地址
        ,imageManagerPath:""                                    //图片修正地址,同imagePath

        //屏幕截图配置区
        ,snapscreenHost: location.hostname                                 //屏幕截图的server端文件所在的网站地址或者ip,请不要加http://
        ,snapscreenServerUrl: "/ue_imageUp" //屏幕截图的server端保存程序,UEditor的范例代码为“URL +"server/upload/php/snapImgUp.php"”
        ,snapscreenPath: ""
        ,snapscreenServerPort: location.port                                   //屏幕截图的server端端口
        //,snapscreenImgAlign: ''                                //截图的图片默认的排版方式

        //word转存配置区
        ,wordImageUrl:"/ue_imageUp"             //word转存提交地址
        ,wordImagePath:""                       //
        //,wordImageFieldName:"upfile"                     //word转存表单名若此处修改,需要在后台对应文件修改对应参数

        //视频上传配置区
        ,getMovieUrl:"/ue_getMovie"                   //视频数据获取地址
        ,videoUrl:"/ue_fileUp"               //附件上传提交地址
        ,videoPath:""                   //附件修正地址,同imagePath
        //,videoFieldName:"upfile"                    //附件提交的表单名,若此处修改,需要在后台对应文件修改对应参数
然后配置web.py的urls映射

urls = (
    '/', 'Index',
    '/ue_imageUp', Ue_ImageUp,
    '/ue_fileUp', Ue_FileUp,
    '/ue_scrawlUp', Ue_ScrawlUp,
    '/ue_getRemoteImage', Ue_GetRemoteImage,
    '/ue_getMovie', Ue_GetMovie,
    '/ue_imageManager', Ue_ImageManager,
)
最后实现这些web.py的class。
