4.3.2. Running Queries Using Python
You can create and run a Python script to achieve the same results as those described in Section 4.1, “API Examples Using Curl”. The following example script describes this approach. First, create an executable file called
sat6api.py and then add the following content:
#!/usr/bin/python
import json
import sys
try:
import requests
except ImportError:
print "Please install the python-requests module."
sys.exit(-1)
SAT_API = 'https://satellite6.example.com/api/v2/'
USERNAME = "admin"
PASSWORD = "password"
SSL_VERIFY = False # Ignore SSL for now
def get_json(url):
# Performs a GET using the passed URL location
r = requests.get(url, auth=(USERNAME, PASSWORD), verify=SSL_VERIFY)
return r.json()
def get_results(url):
jsn = get_json(url)
if jsn.get('error'):
print "Error: " + jsn['error']['message']
else:
if jsn.get('results'):
return jsn['results']
elif 'results' not in jsn:
return jsn
else:
print "No results found"
return None
def display_all_results(url):
results = get_results(url)
if results:
print json.dumps(results, indent=4, sort_keys=True)
def display_info_for_hosts(url):
hosts = get_results(url)
if hosts:
for host in hosts:
print "ID: %-10d Name: %-30s IP: %-20s OS: %-30s" % (host['id'], host['name'], host['ip'], host['operatingsystem_name'])
def main():
host = 'satellite6.example.com'
print "Displaying all info for host %s ..." % host
display_all_results(SAT_API + 'hosts/' + host)
print "Displaying all facts for host %s ..." % host
display_all_results(SAT_API + 'hosts/%s/facts' % host)
host_pattern = 'example'
print "Displaying basic info for hosts matching pattern '%s'..." % host_pattern
display_info_for_hosts(SAT_API + 'hosts?search=' + host_pattern)
environment = 'production'
print "Displaying basic info for hosts in environment %s..." % environment
display_info_for_hosts(SAT_API + 'hosts?search=environment=' + environment)
model = 'RHEV Hypervisor'
print "Displaying basic info for hosts with model name %s..." % model
display_info_for_hosts(SAT_API + 'hosts?search=model="' + model + '"')
if __name__ == "__main__":
main()
You can then run
./sat6api.py from the command line to display the results.
