我正在尝试使用Crossbar.io 0.10.4和Django 1.6.11,尝试关注example here。代码显示您可以配置Crossbar.io以在" /"中提供Django应用程序。 - 但是当我在配置中尝试时,我收到Python导入错误:
ApplicationError: ApplicationError('crossbar.error.invalid_configuration', args = (u"WSGI app module 'apache/django.wsgi' import failed: Import by filename is not supported. - Python search path was ....
我的config.json在这里:
{
"controller": {
},
"workers": [
{
"type": "router",
"realms": [
{
"name": "backstage-producer",
"roles": [
{
"name": "anonymous",
"permissions": [
{
"uri": "*",
"publish": false,
"subscribe": true,
"call": false,
"register": false
}
]
}
]
}
],
"transports": [
{
"type": "web",
"endpoint": {
"type": "tcp",
"port": 8080
},
"paths": {
"/": {
"type": "wsgi",
"module": "apache/django.wsgi",
"object": "application"
},
"ws": {
"type": "websocket",
"debug": false
},
"notify": {
"type": "publisher",
"realm": "backstage-producer",
"role": "anonymous"
},
"static": {
"type": "static",
"directory": "../static"
}
}
}
]
}
]
}
在搜索的Python路径中,不包含我的Django项目目录。通常我将我的特定项目目录附加到我的wsgi文件中的sys.path,但显然工作流程不适用于Crossbar.io。尝试相对导入失败(需要指定" package"参数)和完整路径(与文件名错误导入相同)。
删除" /"的定义不起作用,因为Crossbar.io抱怨必须定义它。
如何使用Crossbar.io正确设置?我的apache / django.wsgi文件如下:参考:
ALLDIRS = ['/usr/local/pythonenv/myapp/lib/python2.6/site-packages']
import os
import sys
import site
# from https://code.google.com/p/modwsgi/wiki/VirtualEnvironments
sys.path.insert(0, '/var/www/myapp/myapp_main/')
sys.path.insert(1, '/var/www/myapp/')
prev_sys_path = list(sys.path)
for directory in ALLDIRS:
site.addsitedir(directory)
new_sys_path = []
for item in list(sys.path):
if item not in prev_sys_path:
new_sys_path.append(item)
sys.path.remove(item)
sys.path[:0] = new_sys_path
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp_main.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
----更新1 ------
根据Daniel的建议,我将文件更改为wsgi.py并将我的配置更改为使用Python模块路径,而不是文件名/目录路径。 Config然后看起来像这样:
"paths": {
"/": {
"type": "wsgi",
"module": "apache.wsgi",
"object": "application"
},
引发同样的例外:
ApplicationError: ApplicationError('crossbar.error.invalid_configuration', args = (u"WSGI app module 'apache.wsgi' import failed: No module named apache.wsgi - Python search path was
我的目录结构是:
Project
|- apache
| |-__init__.py
| |-wsgi.py
|-.crossbar
|-config.json
-------更新2 -------
唯一的解决方案(阅读" hack")我发现将我的项目路径硬编码到crossbar/worker/router.py
中,以便它包含在Python搜索路径列表中:
sys.path.insert(0, '/var/www/myapp/myapp_main/')
sys.path.insert(1, '/var/www/myapp/')
似乎应该有更好的方式...
答案 0 :(得分:3)
错误告诉您在设置中有一个指向WSGI文件的文件路径,而您需要一个Python模块路径。您的WSGI文件实际上应该是项目目录中名为“wsgi.py”的文件(可能是“apache”,这是一个明确不使用Apache的项目的奇怪名称。)
"/": {
"type": "wsgi",
"module": "apache.wsgi",
"object": "application"
},
更新所以我最终找到了config docs:他们真的不想让它变得简单,就像实际提供索引一样。哦,好吧。
看起来您可以为路由器配置提供options
哈希,包括pythonpath
设置:
"workers": [
{
"type": "router",
"options": {
"pythonpath": ["/var/myapp/myapp_main/", "/var/myapp"]
},
...
"transports": {
...
