python-gtmetrix

python-gtmetrix is a Python client library for GTmetrix REST API.

Quickstart:

Install package:

$ pip install python-gtmetrix

Make tests:

Create json with urls:

{
"google": "http://google.com",
}

Start test using json with urls:

from gtmetrix import *
import json

with open('sites.json') as data_file:
list_sites = json.load(data_file)

for key, value in list_sites.items():
    print ("Site: %s - Url: %s" % (key, value))
    gt = GTmetrixInterface('your@email.com', 'api-key')
    my_test = gt.start_test(value)

Fetch results:

my_test.fetch_results(key)

or

results = gt.poll_state_request(key, my_test.test_id)

When test is completed you able to access next data in the files:

results-date = pagespeed_score, yslow_score, page_bytes, page_load_time, page_elements
resources-date= urls to screenshot, har, pagespeed_url, pagespeed_files, yslow_url,  report_pdf, report_pdf_full

List of available params and response attributes you can find at http://gtmetrix.com/api/

Exceptions:

Invalid test request

GTmetrixInvalidTestRequest

The requested test does not exist

GTmetrixTestNotFound

The maximum number of API calls reached

GTmetrixMaximumNumberOfApis

Too many concurrent requests from your IP

GTmetrixManyConcurrentRequests

Example:

from gtmetrix import *

gt = GTmetrixInterface('your@email.com', 'api-key')

try:
    my_test = gt.start_test('http://google.com')
except GTmetrixInvalidTestRequest:
    print 'Something goes wrong'

try:
    results = gt.poll_state_request(my_test.test_id)
except GTmetrixTestNotFound:
    raise Http404

Running Tests & Development:

In order to run the tests you can either checkout from the main repo at GitHub, or download the zip file or what have you.

Create a new virtual environment, however you do that, and run:

pip install -r requirements.txt

Then, make it so you're running off your checkout:

python setup.py develop

Run the tests to make sure you're at a good starting point.

The tests are currently run against Python 2.7.x, Python 3.5.x, and Python 3 .6.x. Do this with:

tox

You should see:

At this point, you will be testing your own checkout and can proceed to fix bugs, improve documentation, etc. For a list of what's needed, see the issue tracker.
