When I control different type of pages, I move my code to another python file. But this way has disadvantage : each time I want to change url hander, I must comback to main.py to config bottom lines about url handler. for example :
app = webapp2.WSGIApplication([('/', MainPage),
('/thanks',ThanksHandler),
('/unit2/signup',Signup),
('/unit2/successful', LoginSuccess)], debug=True)
I try to config handler in app.yaml to prevent dis advantage.
I add file blog.py in same directory and in this file, I have Blog class. And here is my blog.py file:
class Blog(BaseHandler):
def get(self):
self.response.out.write("Hello")
app = webapp2.WSGIApplication([('/blog', Blog)], debug=True)
Here is original file:
> handlers:
> - url: /favicon\.ico static_files: favicon.ico upload: favicon\.ico
- url: /.* script: main.app
and this new file app.yaml:
handlers:
- url: /favicon\.ico static_files: favicon.ico upload: favicon\.ico
- url: /blog/.* script: blog.app
- url: /.* script: main.app
But when I goto: localhost:port/blog : 404: resource not found.
Please help me.
Thanks :)
The /blog/.* url specification from the yaml file does not match the url specification from the blog.py file (/blog). In particular the fact that /blog/.* requires the url to have a slash after blog. If for example you use just /blog in both places it will work. Or you can use /blog/.* in both places.
The url specifiers are matched in the order in which they appear in the yaml file therefore in this particular case /blog/.* will not match on /blog but will match on the last (catch all really) /.* specifier and therefore main.py handler will be loaded and fail to match (no pattern in the call WSGIApplication constructor inside main.py).
Hope this helps.

I made a website which I am temporarily hosting in app engine. I am able to navigate through the pages when I open the HTML files on my computer. It only fails when I head to http://www.alshafarconstruction.appspot.com/index.html.
Error Message:
Error: Not Found
The requested URL /contact.html was not found on this server
app.yaml:

I've checked the dashboard and find that the HTML files are there. I am new to website deployment and design. Can anyone suggest possible errors? I have already visited many sites for a solution.
The documentation hints that static and application files are uploaded separately, so while the files may be there, it might be that they're being uploaded in the application-files part.
You currently have an upload directive telling it to only upload index.html:
- url: /(.*\.html)
static_files: \1
upload: index.html
(actually, it's a regular expression, so it would also upload, for example index#html if it existed)
This suggests that you might want to make that regular expression match all HTML files:
- url: /(.*\.html)
static_files: \1
upload: .*\.html
I am setting up a new GAE project, and I can't get my scripts in sub-directories to work.
EDIT: If I go to localhost:8080/testing_desc.html I don't any errors, just a blank page (view-source is blank, too). Scripts in my root dir work normally. There is a __init__.py in both the root and sub-dir.
Python script example ("/testing/testing_desc.py"):
import webapp2 as webapp
class DescTstPage(webapp.RequestHandler):
def get(self):
html = 'This should work.'
self.response.out.write(html)
app = webapp.WSGIApplication([('/.*', DescTstPage)], debug=True)
app.yaml:
application: blah
version: blah
runtime: python27
api_version: 1
default_expiration: "5d 12h"
threadsafe: false
libraries:
- name: webapp2
version: latest
handlers:
- url: / <-- This one works
script: main.app
- url: /index.html <-- This does NOT work (??)
script: main.app
- url: /(.*?)_desc.html <-- Also does NOT work
script: \1/\1_desc.app
#file not found
- url: /.*
script: file_not_found.app
I have also tried a simpler version of the yaml:
-url: /testing_desc.html
script: /testing/testing_desc.app
When you use WSGI Pyhon27 this will work. Use a dot for the seperator :
-url: /testing_desc.html
script: /testing.testing_desc.app
You are passing a list of routes to your WSGIApplicaiton call. Those routes must match whatever URL is being handled.
('/', DescTstPage) just matches the '/' URL to your handler. /.* matches all routes.
What routes are you setting in testing/testing_desc.app? They must match /testing_desc.html.
To get my scripts working in sub-dir, I changed the app.yaml and /testing/testing_desc.py to this:
app.yaml:
- url: /testing.html
script: testing/testing_desc.py
/testing/testing_desc.py:
app = webapp.WSGIApplication([('/.*', DescTstPage),], debug=True)
def main():
run_wsgi_app(app)
if __name__ == '__main__':
main()
ATM I do not understand how to make the routing work with sub-dir, so I will use this.
The answer is here:
How can i use script in sub folders on gae?
Its not explicitly stated, but in the answer you must change /foo/ to /foo in the WSGIApplication call, which maps to www.bar.com/foo. If you want to map to www.bar.com/foo.html you need to change /foo to /foo.* in the WSGIApplication call AND the url handler in app.yaml to - url: /foo\.html
Can I use this for uploading HTML pages?
app.yaml contents:
application: visualvidya
version: 1
runtime: python
api_version: 1
handlers:
- url: /(.*\.(gif|png|jpg|ico|js|css))
static_files: \1
upload: (.*\.(gif|png|jpg|ico|js|css))
A minimal handlers section for a static site might look something like this:
handlers:
- url: /
static_files: static/index.html
upload: static/index.html
- url: /
static_dir: static
Every site is different, so as Sean pointed out in the comments, you'll want to consult the documentation.
I have all static files same directory as my app.yaml
Now, I have to specific the static files one by one in my app.yaml
application: xxx
version: 1
runtime: python
api_version: 1
handlers:
- url: /
static_files: index.html
upload: index.html
- url: /style.css
static_files: style.css
upload: style.css
- url: /android.png
static_files: android.png
upload: android.png
- url: /logo.png
static_files: logo.png
upload: logo.png
- url: /helloworld.py
script: helloworld.py
Is there any easier way for me to specific all my static files? (Provide they are same directory level as app.yaml)
I try
- url: /
static_files: index.html
static_dir: \.
upload: index.html
It won't work.
Fatal error when loading application configuration:
Unexpected attribute "static_dir" for mapping type static_files.
in "C:\Projects\xxx-website\app.yaml", line 12, column 1
As others suggested you can put your files in the static folder and have an app.yaml that looks like this (so you don't have to enter manually every file):
https://gist.github.com/3031499
You can also specific handlers at the top like:
- url: /counter
script: counter.app
- url: /(.*\.rar)
script: download.app
Any reason to try and do this? Place them all in the static directory.
I'm migrating my gae app to python 2.7. This is my new app.yaml:
application: webfaze
version: main
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /mapreduce(/.*)?
script: mapreduce/main.application
- url: /(.*\.(html|css|js|gif|jpg|png|ico|swf))
static_files: static/\1
upload: static/.*
expiration: "1d"
- url: .*
script: main.application
- url: /task/.*
script: main.application
login: admin
But I get this error message:
Error parsing yaml file:
Invalid object:
threadsafe cannot be enabled with CGI handler: mapreduce/main.application
in "webfaze/app.yaml", line 22, column 1
Can you tell me how to resolve the error?
Checking the source code, it looks that you need to define your handlers' path without any slash:
if (handler.script and (handler.script.endswith('.py') or
'/' in handler.script)):
raise appinfo_errors.ThreadsafeWithCgiHandler(
'threadsafe cannot be enabled with CGI handler: %s' %
handler.script)
Move application.py to the root of your project and modify the handler's path accordingly.
Change:
- url: /mapreduce(/.*)?
script: mapreduce/main.application
To:
- url: /mapreduce(/.*)?
script: mapreduce.main.application
You may also need to add an __init__.py to the 'mapreduce' folder if one doesn't exist there already. That will make the python interpret the folder as a module.
