django使用ueditor服务器端配置

之前我们说到了vue中使用editor，可以使用vue-ueditor-wrap，其实python中也有人帮我们集成了ueditor，今天我们不打算从零写ueditor服务端接口，参考**DjangoUeditor3**定制属于我们自己的ueditor服务端接口

我们来打开DjangoUeditor3的仓库https://github.com/twz915/DjangoUeditor3，

拷贝项目源码

新建视图

新建我们的ueditor视图接口ueditor_view.py

拷贝仓库中的DjangoUeditor3/DjangoUeditor/views.py文件内容到ueditor_view.py

新建配置文件

视图中引用了自己的一个setting，包含自己ueditor上传的一些设置，我们也一起拿过来

在我们当前应用中创建settings.py

DjangoUeditor3/DjangoUeditor/settings.py复制到其中

创建接口`url`

1 2	from app.ueditorviews import get_ueditor_controller path('controller',get_ueditor_controller)

get_ueditor_controller就是我们的入口

连接前端`vue`

将vue使用ueditor前端配置中的serverUrl配置为我们刚才的接口地址，我这里都在本地测试，端口不同

1	serverUrl: 'http://localhost:8000/controller',

初试接口

点击上传图片无反应

默认请求接口带了一个action和callback的参数，200接口访问成功，但是却没有取回任何数据，观察下之前我们用到的测试服务接口，是有返回数据的，对方是用的php，我们来看下ueditor_view.py源码

控制台也打印了如下：

Cross-Origin Read Blocking (CORB) blocked cross-origin response http://localhost:8000/controller?action=config&callback=bd__editor__ve7qge with MIME type text/html. See https://www.chromestatus.com/feature/5629709824032768 for more details.

@csrf_exempt
def get_ueditor_controller(request):
    """获取ueditor的后端URL地址"""
    action = request.GET.get("action", "")
    reponseAction = {
        "config": get_ueditor_settings,
        "uploadimage": UploadFile,
        "uploadscrawl": UploadFile,
        "uploadvideo": UploadFile,
        "uploadfile": UploadFile,
        "catchimage": catcher_remote_image,
        "listimage": list_files,
        "listfile": list_files
    }
    return reponseAction[action](request)

可以看出来做了一个类似反射的东西，初始连接带了action参数为config，所以对应的把我们给踢到get_ueditor_settings方法中了，继续跟进到这个方法

@csrf_exempt
def get_ueditor_settings(request):
    json_data = json.dumps(
        USettings.UEditorUploadSettings,
        ensure_ascii=False)
    return HttpResponse(json_data, content_type="application/javascript")

我们来打印下json_data

{"imageActionName": "uploadimage", "imageMaxSize": 10485760, "imageFieldName": "upfile", "imageUrlPrefix": "http://localhost:8000", "imagePathFormat": "", "imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], "scrawlActionName": "uploadscrawl", "scrawlFieldName": "upfile", "scrawlMaxSize": 10485760, "scrawlUrlPrefix": "", "scrawlPathFormat": "", "snapscreenActionName": "uploadimage", "snapscreenPathFormat": "", "snapscreenUrlPrefix": "", "catcherLocalDomain": ["127.0.0.1", "localhost", "img.baidu.com"], "catcherPathFormat": "", "catcherActionName": "catchimage", "catcherFieldName": "source", "catcherMaxSize": 10485760, "catcherAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], "catcherUrlPrefix": "", "videoActionName": "uploadvideo", "videoPathFormat": "", "videoFieldName": "upfile", "videoMaxSize": 102400000, "videoUrlPrefix": "", "videoAllowFiles": [".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg", ".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid"], "fileActionName": "uploadfile", "filePathFormat": "", "fileFieldName": "upfile", "fileMaxSize": 204800000, "fileUrlPrefix": "", "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": "", "imageManagerListSize": 30, "imageManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], "imageManagerUrlPrefix": "", "fileManagerActionName": "listfile", "fileManagerListPath": "", "fileManagerUrlPrefix": "", "fileManagerListSize": 30, "fileManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp", ".tif", ".psd.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", ".exe", ".com", ".dll", ".msi"]}

有返回数据，可以前台没有响应，再仔细观察下除了action还带了一个callback参数，我们还没用到，刷新发下，这个callback的值每次还随机变动，跟原示例返回值比较下，外层少了一个callback(),我们简单来组装下这个参数。

1 2	callback = request.GET.get('callback') json_data = '%s(%s)' % (callback,json_data)

再次测试，控制台没有警告了，且我们也取到返回值了

bd__editor__dzdteh({"imageActionName": "uploadimage", "imageMaxSize": 10485760, "imageFieldName": "upfile", "imageUrlPrefix": "http://localhost:8000", "imagePathFormat": "", "imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], "scrawlActionName": "uploadscrawl", "scrawlFieldName": "upfile", "scrawlMaxSize": 10485760, "scrawlUrlPrefix": "", "scrawlPathFormat": "", "snapscreenActionName": "uploadimage", "snapscreenPathFormat": "", "snapscreenUrlPrefix": "", "catcherLocalDomain": ["127.0.0.1", "localhost", "img.baidu.com"], "catcherPathFormat": "", "catcherActionName": "catchimage", "catcherFieldName": "source", "catcherMaxSize": 10485760, "catcherAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], "catcherUrlPrefix": "", "videoActionName": "uploadvideo", "videoPathFormat": "", "videoFieldName": "upfile", "videoMaxSize": 102400000, "videoUrlPrefix": "", "videoAllowFiles": [".flv", ".swf", ".mkv", ".avi", ".rm", ".rmvb", ".mpeg", ".mpg", ".ogg", ".ogv", ".mov", ".wmv", ".mp4", ".webm", ".mp3", ".wav", ".mid"], "fileActionName": "uploadfile", "filePathFormat": "", "fileFieldName": "upfile", "fileMaxSize": 204800000, "fileUrlPrefix": "", "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": "", "imageManagerListSize": 30, "imageManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], "imageManagerUrlPrefix": "", "fileManagerActionName": "listfile", "fileManagerListPath": "", "fileManagerUrlPrefix": "", "fileManagerListSize": 30, "fileManagerAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp", ".tif", ".psd.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", ".exe", ".com", ".dll", ".msi"]})

测试单图片上传，应该大多数人已经可以成功上传了。

图片上传成功，却提示上传错误，不显示图片

这部分都是跨域问题，解决办法如下：UploadFile函数返回值做修改，添加一个header即可。

1
2
3

response = HttpResponse(json.dumps(return_info, ensure_ascii=False))
response['Access-Control-Allow-Headers'] = '*'
return response

测试多图片

点击上传多张图片按钮会出现以下提示：

控制台：

Access to XMLHttpRequest at 'http://localhost:8000/controller?action=uploadimage&encode=utf-8' from origin 'http://localhost:8080' has been blocked by CORS policy: Request header field x_requested_with is not allowed by Access-Control-Allow-Headers in preflight response.

图片上传失败；跨域问题；而且访问接口请求成功200，请求方法却是options以前没有用到过该方法，百度查了下，大概意思是说这个浏览器自己发的，先试探下服务器允不允许。我在ueditor_view入口函数包括上传函数中都打印请求，很显然什么也没打印出来，真是不知道这个options方法会走到程序的哪里，甚至打算将这个视图写成cbv，走走options函数试试。

后来想到初始使用vue连django时也出现了该提示，详见：Access-Control-Allow-Origin跨域问题，当时用的是

django-cors-headers，按照文中内容配置好

主要配置：

1
2
3

CORS_ALLOW_HEADERS = [
    'x-requested-with',
]

测试多图片上传，完美
