我在Apache / mod-wsgi服务的Django应用程序中使用FCKEditor。我不想只为FCKEditor安装php而且我看到FCKEditor通过Python提供图像上传和图像浏览。我还没有找到关于如何设置这一切的良好指示。
所以目前Django使用这个设置运行wsgi接口：
import os, sys
DIRNAME = os.sep.join(os.path.abspath(__file__).split(os.sep)[:-3])
sys.path.append(DIRNAME)
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
在编辑器＆gt; filemanager-＆gt;连接器 - ＆gt; py目录中的fckeditor中有一个名为wsgi.py的文件：
from connector import FCKeditorConnector
from upload import FCKeditorQuickUpload
import cgitb
from cStringIO import StringIO
# Running from WSGI capable server (recomended)
def App(environ, start_response):
"WSGI entry point. Run the connector"
if environ['SCRIPT_NAME'].endswith("connector.py"):
conn = FCKeditorConnector(environ)
elif environ['SCRIPT_NAME'].endswith("upload.py"):
conn = FCKeditorQuickUpload(environ)
else:
start_response ("200 Ok", [('Content-Type','text/html')])
yield "Unknown page requested: "
yield environ['SCRIPT_NAME']
return
try:
# run the connector
data = conn.doResponse()
# Start WSGI response:
start_response ("200 Ok", conn.headers)
# Send response text
yield data
except:
start_response("500 Internal Server Error",[("Content-type","text/html")])
file = StringIO()
cgitb.Hook(file = file).handle()
yield file.getvalue()
我需要通过修改我的django wsgi文件来正确地为fckeditor部分提供服务或者让apache在单个域上正确地为django和fckeditor服务，这两个方面有两个一起工作。
解决方案 2
编辑：最终我对这个解决方案也不满意所以我做了一个 Django app 负责文件上传和浏览。
这是我在阅读fckeditor代码后最终共同攻击的解决方案：
import os, sys
def fck_handler(environ, start_response):
path = environ['PATH_INFO']
if path.endswith(('upload.py', 'connector.py')):
sys.path.append('/#correct_path_to#/fckeditor/editor/filemanager/connectors/py/')
if path.endswith('upload.py'):
from upload import FCKeditorQuickUpload
conn = FCKeditorQuickUpload(environ)
else:
from connector import FCKeditorConnector
conn = FCKeditorConnector(environ)
try:
data = conn.doResponse()
start_response('200 Ok', conn.headers)
return data
except:
start_response("500 Internal Server Error",[("Content-type","text/html")])
return "There was an error"
else:
sys.path.append('/path_to_your_django_site/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'your_django_site.settings'
import django.core.handlers.wsgi
handler = django.core.handlers.wsgi.WSGIHandler()
return handler(environ, start_response)
application = fck_handler
其他提示
介绍如何嵌入FCK编辑器并启用图像上传。
首先，您需要编辑fckconfig.js以更改图像上传 指向服务器内部某个URL的URL。
FCKConfig.ImageUploadURL = "/myapp/root/imageUploader";
这将指向用于接收上载的服务器相对URL。 FCK将使用CGI变量将上载的文件发送到该处理程序 名称“NewFile”使用multipart / form-data编码。不幸的是你 将不得不实现/ myapp / root / imageUploader，因为我不认为 FCK分发内容可以很容易地适应其他框架。
imageUploader应该提取NewFile并存储它 在服务器上的某个地方。 / myapp / root / imageUploader生成的响应应该模拟 在/editor/.../fckoutput.py中构造的HTML。 这样的东西（whiff模板格式）
{{env
whiff.content_type: "text/html",
whiff.headers: [
["Expires","Mon, 26 Jul 1997 05:00:00 GMT"],
["Cache-Control","no-store, no-cache, must-revalidate"],
["Cache-Control","post-check=0, pre-check=0"],
["Pragma","no-cache"]
]
/}}
<script>
//alert("!! RESPONSE RECIEVED");
errorNumber = 0;
fileUrl = "fileurl.png";
fileName = "filename.png";
customMsg = "";
window.parent.OnUploadCompleted(errorNumber, fileUrl, fileName, customMsg);
</script>
顶部的{{env ...}}内容表示内容类型和 建议发送的HTTP标头。 fileUrl应该是Url 用于在服务器上查找图像。
以下是获取html片段的基本步骤 生成FCK编辑器小部件。唯一棘手的部分是你必须把 正确的客户端识别到os.environ - 这很难看 但这就是FCK库现在的工作方式（我提交了一个错误 报告）。
import fckeditor # you must have the fck editor python support installed to use this module
import os
inputName = "myInputName" # the name to use for the input element in the form
basePath = "/server/relative/path/to/fck/installation/" # the location of FCK static files
if basePath[-1:]!="/":
basePath+="/" # basepath must end in slash
oFCKeditor = fckeditor.FCKeditor(inputName)
oFCKeditor.BasePath = basePath
oFCKeditor.Height = 300 # the height in pixels of the editor
oFCKeditor.Value = "<h1>initial html to be editted</h1>"
os.environ["HTTP_USER_AGENT"] = "Mozilla/5.0 (Macintosh; U;..." # or whatever
# there must be some way to figure out the user agent in Django right?
htmlOut = oFCKeditor.Create()
# insert htmlOut into your page where you want the editor to appear
return htmlOut
以上是未经测试的，但它是基于以下测试的。
以下是如何使用mod-wsgi使用FCK编辑器： 从技术上讲，它使用了WHIFF的几个功能（参见 WHIFF.sourceforge.net ）， - 实际上它是WHIFF发行版的一部分 - 但 WHIFF功能很容易删除。
我不知道如何在Django中安装它，但如果 Django允许您轻松安装wsgi应用程序 应该能够做到。
注意：FCK允许客户端注入几乎任何东西 进入HTML页面 - 你会想要过滤返回的邪恶值 攻击。 （例如：参见whiff.middleware.TestSafeHTML中间件 如何做到这一点的一个例子。）

顺便说一句：谢谢。无论如何，我需要调查一下。
