Общие сведения можно найти в посте Python: модуль requests.
В примере ниже – пример его использования.
Функция cloud_put() выполняет деплой данных (XML и DLL файлы) в базу данных Cassandra через API нашего приложения:
def cloud_put(logger, user, password, base_url, deploy_urls_list, deploy_files_list, deploy_names_list):
"""Make API request with PUT
Executes session.put() for each URL and FILE in deploy_files_list and deploy_names_list lists
Called in deploy_ci() function"""
session = requests.Session()
session.auth = (user, password)
session.headers.update({'user-agent': 'RDSmanager'})
# check count in each element, must be identically
logger.logger.info('Counting items for deploy...')
if not len(deploy_urls_list) == len(deploy_files_list):
logger.logger.info('ERROR: items in `deploy_urls_list` not equal items in `deploy_files_list`')
sys.exit(1)
elif not len(deploy_files_list) == len(deploy_names_list):
logger.logger.info('ERROR: items in `deploy_files_list` not equal items in `deploy_names_list`')
sys.exit(2)
else:
logger.logger.info('Count seems OK.')
# checking connection
try:
data_check = session.get(base_url)
data_check.raise_for_status()
except requests.exceptions.ConnectionError as error:
logger.logger.info('ERROR: %s' % error)
sys.exit(5)
# m_url - URL with UUID, e.g. https://www.dev.domain.com/cloudlibrary/data/4ac11ad6-a391-455c-bd6b-d205b655926b
# m_file - file on local filesystem to deploy, e.g. d:RDSbuilddirPlugins_xmlsProductGroupEditor.unity3d
# m_name - just module name, e.g. UnityUI
for m_url, m_file, m_name in zip(deploy_urls_list, deploy_files_list, deploy_names_list):
logger.logger.info('Deploying file: %snURL: %s File: %s' % (m_name, m_url, m_file))
try:
with open(m_file, 'rb') as infile:
data_put = session.put(m_url, data=infile)
data_put.raise_for_status()
logger.logger.info('Result code: %sn' % data_put.status_code)
except requests.exceptions.HTTPError as error:
logger.logger.info('ERROR: %s' % error)
sys.exit(7)
except requests.exceptions.TooManyRedirects:
logger.logger.info('Authentication failed!')
sys.exit(6)
Она в свою очередь вызывается из функции deploy_ci():
def deploy_ci(logger, rds_basedir, config_name):
"""Build-server deployment part"""
logger.logger.info('Running CI server deploy')
# set of defaults, if variables not found
defaults = {'base_url': 'https://www.dev.domain.com/cloudlibrary/',
'user': 'user',
'password': 'pass', }
...
# running deploy with session.put() in cloud_put() function
cloud_put(logger, user, password, base_url, deploy_urls_list, deploy_files_list, deploy_names_list)
