bottle

问题 What is the difference between running bottle script like this from bottle import route, run @route('/') def index(): return 'Hello!' run(server='gunicorn', host='0.0.0.0', port=8080) with command python app.py and this from bottle import route, default_app @route('/') def index(): return 'Hello!' app = default_app() with command gunicorn app:app --bind='0.0.0.0:8080' 回答1: Essentially nothing. From the bottle source code for the GunicornServer here you can see that a basic application is

问题 I currently have a one-page Bottle project working through localhost:8080 . For the purposes of this question, assume that single page is naught but a basic short-polling chat, retrieving chatline objects from Python that contain only the sender's name and the body of the message. Those chatline objects are stored in chat objects, with the project allowing multiple chats. The chat and sender is determined by the URL. For example, if a chatline is sent from localhost:8080/chat/23/50 , it is

问题 I need to generate PDF document using the Bottle framework. I tried similar to Django but that didn't work: @bottle.route('/pd') def create_pdf(): response.headers['Content-Type'] = 'application/pdf; charset=UTF-8' response.headers['Content-Disposition'] = 'attachment; filename="test.pdf"' from io import BytesIO buffer = BytesIO() from reportlab.pdfgen import canvas p = canvas.Canvas(buffer) p.drawString(100,100,'Hello World') p.showPage() p.save() pdf = buffer.getvalue() buffer.close()

问题 I'm using PyCharm 3.4.1 and learning MongoDB from Mongo University. In the code, they have us using Python to create html pages using the MVC pattern with bottle. When I add a file of type .tpl to the editor in PyCharm, there is no "intellisense" or support for the model in the code. Changing it to be in the list of html file types helps some, but no python support in the editor. Is there a plugin or some other change i can make to support editing better? Seems someone else asked something

问题 I've got a problem with bottle, the _initialize function is run twice. Example app: @route("/index") def index(): return "bang" def _initialize(): print("bam") if __name__ == "__main__": _initialize() run(reloader=True, host="localhost", port = 8990) The output is: bam bam Bottle v0.11.rc1 server starting up (using WSGIRefServer())... Listening on http://localhost:8080/ Hit Ctrl-C to quit. Why is it happening and how can I do such pre init in bottle? 回答1: The problem is the reloader=True

问题 So I've done some reading about Python web frameworks (or servers?), mostly Tornado and Bottle but also FAPWS3, and there are still some grey areas. First, these three web frameworks are all said to be fast, yet they all include a web server written in Python (except FAPWS3) which should be put behind nginx/Apache. Isn't this reducing the performance? I mean, we know that Python is much slower than C, why not only use nginx, or at worst, only the included Python web server? 回答1: First of,

问题 I would like to know if it is possible to enable gzip compression for Server-Sent Events (SSE ; Content-Type: text/event-stream). It seems it is possible, according to this book: http://chimera.labs.oreilly.com/books/1230000000545/ch16.html But I can't find any example of SSE with gzip compression. I tried to send gzipped messages with the response header field Content-Encoding set to "gzip" without success. For experimenting around SSE, I am testing a small web application made in Python

问题 I'm new to using Python and have came across a problem when trying to reference my style-sheet from a .tpl document. My python, template and css documents are all in the same directory however when I load the page using the CMD to "localhost:8080" it shows the template without the style being applied. In my template document index.tpl i have referenceed three stylesheets: <link rel="stylesheet" type="text/css" href="demo.css" /> <link rel="stylesheet" type="text/css" href="style.css" /> <link

问题 When I try to assign something to the session dictionary using beaker, I get the following error: Traceback (most recent call last): rv = callback(*a, **ka) File "controllers.py", line 30, in login s['email'] = email TypeError: 'NoneType' object does not support item assignment 1.0.0.127.in-addr.arpa - - [12/Feb/2012 18:48:52] "POST /login HTTP/1.1" 500 746 where s = bottle.request.environ.get('beaker.session') I follow the tutorial at the bottle FAQ. 回答1: session_opts = { 'session.type':

问题 I have got various modules in which I use Python logging heavily. When I import them into the main module like in the Python documentation and try to run it, I don't get any output from the logging. Has anyone got any idea what is happening? Logging is called in the module imported by the public module imported below (the piece of code is too large to be put up here). The piece of code below is where the whole program is run and the logging is initialized: import logging from bottle import
