WebObs Python Client

Project description

webobsclient

WebObs Python client.

Installation

webobsclient is available on PyPI. You can install the latest version by typing this command:

pip install -U webobsclient

Requirements

  • Python 3.5+
  • httplib2
  • six
  • pandas
  • sqlalchemy

You can also find all dependency packages in requirements.txt file.

Making Requests

You need to specify username and password credentials of your WebObs login access in order to make a request. For example:

import webobsclient

client = webobsclient.MC3Client(username='USER', password='PASSWORD')
response, content = client.request(
    slt=0, y1=2019, m1=6, d1=15, h1=0, y2=2019, m2=7, d2=15, h2=4, type='ALL',
    duree='ALL', ampoper='eq', amplitude='ALL', locstatus=0, located=0,
    hideloc=0, mc='MC3', dump='bul', graph='movsum')

print(response)
print(content)

Sometimes, using y1, m1, d1, and h1 options are inconvenient. You can use starttime, and endtime options indicating time range of your request. For example:

import webobsclient

client = webobsclient.MC3Client(username='USER', password='PASSWORD')
response, content = client.request(
    starttime='2019-06-15 12:00:00', endtime='2019-07-15 12:00:00', slt=0, type='ALL',
    duree='ALL', ampoper='eq', amplitude='ALL', locstatus=0, located=0,
    hideloc=0, mc='MC3', dump='bul', graph='movsum')

print(response)
print(content)

Note that starttime and endtime options are only available on MC3Client.

Another example for Sefran3 client:

import webobsclient

client = webobsclient.Sefran3Client(username='USER', password='PASSWORD')
response, content = client.request(
    s3='SEFRAN', mc3='MC3', date='201907150829', id=550)

print(response)
print(content)

Note that date time in the request and WebObs are both in UTC time zone. If you're using local time zone, you should convert it to UTC time zone before making the request.

Parsing MC3 CSV Bulletin

webobsclient provides some utility classes to enable parsing MC3 CSV from WebObs response:

import webobsclient
from webobsclient.parser import MC3Parser

client = webobsclient.MC3Client(username='USER', password='PASSWORD')

response, content = client.request(
    type='VTA', starttime='2019-10-01', endtime='2019-10-31', slt=0,
    duree='ALL', ampoper='eq', amplitude='ALL', locstatus=0, located=0,
    hideloc=0, mc='MC3', dump='bul', graph='movsum')

parser = MC3Parser(content, use_local_tz=True)
print(parser.to_dictionary())

The above example request VTA earthquake event to the WebObs MC3 bulletin from 2019-10-01 to 2019-10-31. We create a parser instance with use_local_tz=True option. This will convert any columns with date time type from UTC to Asia/Jakarta time zone because MC3Parser class uses Asia/Jakarta time zone by default. Method to_dictionary() will convert MC3 CSV to Python dictionary.

MC3 CSV is parsed using pre-defined column shemas. You can see the column schemas in webobsclient/schemas.py.

For more information about available methods and options, see the source in webobsclient/parser.py.

Changing the WebObs Host

This package primarily used at BPPTKG to interact with our WebObs server. Default WebObs host in library is 192.168.0.25. If your WebObs host is different, you can change the WebObs host as follows:

import webobsclient

client = webobsclient.MC3Client(username='USER', password='PASSWORD')
client.api.host = '192.168.5.10'

Supported WebObs Clients

Currently only WebObs MC3 and Sefran3 is supported. More client will be added in the future version.
