python3、Django中使用Uediter百度富文本编辑器的配置方法

ueditor.all.js --- ueditor的入口，用于初始化插件等作用

ueditor.config.js --- ueditor完整配置项

controller.jsp ---- 相当于是一个action方法，用于请求返回config.json 文件，这个主要就是文件上传的控制后台，与其他语言的区别也就是在此，主要重写此文件。

config.json ----- 上传等功能都是在这个文件里配置

uEditor与后台交互的逻辑：

1.编辑器初始化时，异步请求后台处理页面，处理程序应该返回一套json格式的配置信息，请求地址携带的参数为action=config

2.点击图片上传按钮，异步请求后台处理页面，请求地址携带参数为action=uploadimage

3.点击视频上传按钮，异步请求后台处理页面，请求地址携带参数为action=uploadvideo

4.点击附件上传按钮，异步请求后台处理页面，请求地址携带参数为action=uploadfile

5.点击多图上传中的在线图片选项卡，异步请求后台处理页面，请求地址携带参数为action=listimage

6.点击附件上传的在线文件选项卡，异步请求后台处理页面，请求地址携带参数为action=listfile

7.点击涂鸦按钮后，异步请求后台处理页面，请求地址携带参数为action=uploadscrawl

主要步骤：

一、下载uediter，我这里下载的是php版本的，将其放置在项目的某一位置，我这里放在/static/js/base/plugins/下，并在项目下的url.py中配置uediter所在目录的静态文件路径：

from django.views.static import serve

path(‘ue/(?P.*)‘, serve, {‘document_root‘: os.path.dirname(__file__).replace(‘\\‘, ‘/‘) + "/static/js/base/plugins/uediter"}),  # uediter

二、在根目录下新建ueconfig.json文件，配置以下信息：

{"imageActionName": "uploadimage", 
    "imageFieldName": "upfile", 
    "imageMaxSize": 2048000, 
    "imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"],
    "imageCompressEnable": true, 
    "imageCompressBorder": 1600, 
    "imageInsertAlign": "none", 
    "imageUrlPrefix": "/static/upload/image/",
    "imagePathFormat": "image/{yyyy}{mm}{dd}/{time}{rand:6}", 

    "scrawlActionName": "uploadscrawl",
    "scrawlFieldName": "upfile", 
    "scrawlPathFormat": "/images/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}",
    "scrawlMaxSize": 2048000, 
    "scrawlUrlPrefix": "/static/upload/image/",
    "scrawlInsertAlign": "none",

    "snapscreenActionName": "uploadimage", 
    "snapscreenPathFormat": "/images/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}", 
    "snapscreenUrlPrefix": "//static/upload/image/",
    "snapscreenInsertAlign": "none", 

    "catcherLocalDomain": ["127.0.0.1", "localhost", "img.baidu.com"],
    "catcherActionName": "catchimage", 
    "catcherFieldName": "source", 
    "catcherPathFormat": "/images/upload/image/{yyyy}{mm}{dd}/{time}{rand:6}", 
    "catcherUrlPrefix": "/static/upload/image/",
    "catcherMaxSize": 2048000, 
    "catcherAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], 

    "videoActionName": "uploadvideo", 
    "videoFieldName": "upfile", 
    "videoPathFormat": "upload/video/{yyyy}{mm}{dd}/{time}{rand:6}", 
    "videoUrlPrefix": "/static/upload/image/",
    "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": "file/{yyyy}{mm}{dd}/{time}{rand:6}", 
    "fileUrlPrefix": "/static/upload/image/",
    "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": "/upload/onlineimages/", 
    "imageManagerListSize": 20, 
    "imageManagerUrlPrefix": "/static/upload/image/",
    "imageManagerInsertAlign": "none",
    "imageManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], 

    "fileManagerActionName": "listfile", 
    "fileManagerListPath": "/upload/onlinefiles/", 
    "fileManagerUrlPrefix": "/static/upload/image/",
    "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"
    ] 
}

ueconfig.json

注意修改几处关键路径信息：

"imageUrlPrefix": "/upload/images/"修改为自己项目中图片上传后保存的位置，demo中是/upload/images/这个目录    
"scrawlUrlPrefix": "/upload/images/", 修改为自己项目中涂鸦     
"snapscreenUrlPrefix": "/upload/images/", 截图保存位置     
"catcherUrlPrefix": "/upload/images/", 网络图片保存位置     
"videoUrlPrefix": "/upload/vedio/"   视频文件保存地址    
 "fileUrlPrefix": "/upload/files/" 附件保存地址     
"imageManagerUrlPrefix": "/upload/onlineimages/", 在线图片所在位置，在线图片实际就是服务器为用户提供的可选图片    
 "fileManagerUrlPrefix": "/upload/onlinefiles/"  在线附件所在位置，在线附件实际就是服务器为用户提供的可选附件

三、设置上面的ueconfig.json文件的所在目录的静态路径，在项目下的url.py中：

from django.views.static import serve 
path(‘upload/(?P.*)‘, serve, {‘document_root‘: (os.path.dirname(__file__)+"/static/upload").replace(‘\\‘,‘/‘) }),  # 上传文件

四、需要确保ueconfig.json中的路径文件存在，images、vedio、 files、onlinefiles、onlineimages几个子目录

五、设置controller.py文件，这个文件主要是加载uediter的时候，异步请求视图函数

View Code

配置此试图函数的路由，我是在应用下的url中设置的路由，这个根据自己的实际路径进行配置：

from admin.views.controller import *
path(r‘ueEditorControler‘, handler)

六、配置工作最后一步，将”ueditor.config.js”文件的

, serverUrl: URL + "/net/controller.ashx"

修改为

 , serverUrl: "/ueEditorControler"

主要就是在uediter.config.js中出发的请求这个视图函数，调用相应的后台

配置完成！

接下来是在js中使用编辑器：

完成！
