wsgi

问题 So I've been stumped by this problem for a day now. I'm relatively new to AWS EC2 so have been experimenting with Python Flask apps on it. I have an Ubuntu instance, and can get a flask app to run fine on it using Apache2 and WSGI. Only problem is whenever I put a line into my app that requests either a read or a write on the file system the server errors, but the error logs don't produce an error. Here's the function with some debug prints that errors the site: def cleanup_temps(): basePath

问题 I tried to configure WSGI with wsgi.py in my project folder import os import sys sys.path.append(os.path.join(os.environ['OPENSHIFT_REPO_DIR'])) os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings' virtenv = os.environ['OPENSHIFT_HOMEDIR'] + 'python/virtenv/' os.environ['PYTHON_EGG_CACHE'] = os.path.join(virtenv, 'lib/python2.7/site-packages') virtualenv = os.path.join(virtenv, 'bin/activate_this.py') try: execfile(virtualenv, dict(__file__=virtualenv)) except IOError: pass # # IMPORTANT

问题 I keep getting the following error when deploying an Azure Web using Flask: Unhandled exception in wfastcgi.py: Traceback (most recent call last): File "D:\home\python364x64\wfastcgi.py", line 791, in main env, handler = read_wsgi_handler(response.physical_path) File "D:\home\python364x64\wfastcgi.py", line 633, in read_wsgi_handler handler = get_wsgi_handler(os.getenv("WSGI_HANDLER")) File "D:\home\python364x64\wfastcgi.py", line 603, in get_wsgi_handler handler = getattr(handler, name)

问题 I have a small asynchronous server implemented using bottle and gevent.wsgi. There is a routine used to implement long poll that looks pretty much like the "Event Callbacks" example in the bottle documentation: def worker(body): msg = msgbus.recv() body.put(msg) body.put(StopIteration) @route('/poll') def poll(): body = gevent.queue.Queue() worker = gevent.spawn(worker, body) return body Here, msgbus is a ZMQ sub socket. This all works fine, but if a client breaks the connection while worker

问题 I would like to write doctests for my pyramid web app, using the webtest module. I tried it like this: from my_webapp import main from webtest import TestApp app = TestApp(main({})) result = app.get('/') This raises a KeyError (because some.url is not known) when my code reaches this line: url = request.registry.settings['some.url'] The value of some.url is specified in the paster ini file of my application. Is there a simple way to use my development.ini when running my test code? I did not

问题 So typically I am too stubborn to use forum sites myself (call me proud), but this has been driving me absolutely mad. My goal is simply to start Chrome on a server machine, through that server's python WSGI script . I am aware of the bug that prevents Python from using Popen under WSGI, but I've figured out what seemed like a workable (albeit somewhat hack-y) solution: instead of calling Popen with the actual command, I created a .bat and called the bat through Popen with the shell argument

问题 I'm writing a bare bones Python wsgi application and am getting stumped by module import errors. I have a .py file in the current directory which initially failed to import. By adding sys.path.insert(0, '/Users/guhar/Sites/acom') the import of the module worked. But I now try and import a module that I had installed via easy_install and it fails to import. I tried setting sys.path.insert(0, '/Library/Python/2.5/site-packages/') which contains the egg file, but to no avail. I would've thought

问题 From the shell this python code which start and communicates with a node.js process works fine: > from subprocess import * > js = "(function(m) { console.log(m) })('hello world')" > (out,err) = Popen(["node"], stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=False).communicate(js) > out "hello world\n" But when I run the same code from within uwsgi I instead get this in err : 'FATAL ERROR: v8::Context::New() V8 is no longer usable\n' Any insights from either the wsgi community or the node.js

问题 Is it possible for CherryPy to redirect HTTP to HTTPS. Lets for example say the code below is http://example.com if someone visits via https://example.com I want them to be redirected to the plain HTTP URL (301 redirect maybe?) how do I accomplish this? #!/usr/bin/env python from pprint import pformat from cherrypy import wsgiserver def app(environ, start_response): status = '200 OK' response_headers = [('Content-type', 'text/plain')] start_response(status, response_headers) return [pformat

问题 While hitting a REST resource ( my_resource ) in Python, the uWSGI server is throwing the following error in its log: SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request my_resource (ip <my_ip>) !!! uwsgi_response_write_body_do(): Broken pipe [core/writer.c line 164] IOError: write error It seems to be related to a timeout (the client disconnected before the request could finish processing). What sort of timeout is this and how can it be fixed? 回答1: it
