httping
positional arguments:
url URL to be checked
optional arguments:
-h, --help show this help message and exit
-c CONFIG_FILE, --config-file CONFIG_FILE
Path to the configuration file. Defaults to "config.ini".
-v, --verbose Enables verbose mode. Higher values increase verbosity level. Default is 1.
-q, --quiet Enables quiet mode. Suppresses all messages. Default is 0.
-i INTERVAL, --interval INTERVAL
Interval time in seconds between checks. Default is 1 second.
-m METHOD, --method METHOD
HTTP method to use (e.g., GET, POST). Default is "GET".
-t TIMEOUT, --timeout TIMEOUT
Timeout in seconds for each HTTP request. Default is 10 seconds.
-b BASE_DIR, --base-dir BASE_DIR
Base directory for httping operations. Default is the current working directory.
--success SUCCESS [SUCCESS ...]
Criteria for success. Can specify multiple criteria. Default is ["status_code==200"].
--logical-operator {and,or}
Logical operator for evaluating success criteria. Choices are "and", "or". Default is "and".
--ignore-ssl IGNORE_SSL
Ignores SSL certificate validation if set to True. Default is True.
-d DATA, --data DATA Data to be sent in the HTTP request body. Expected in JSON format. Default is an empty dictionary.
--headers HEADERS HTTP headers to be sent with the request. Expected in JSON format. Default is an empty dictionary.
-w WORKERS, --workers WORKERS
Maximum number of worker processes. Default is 10.
--stack-limit STACK_LIMIT
Error stack limit. Default is 5.
--dynamic-increase-stack-limit DYNAMIC_INCREASE_STACK_LIMIT
Dynamically increases the error stack limit if set to True. Default is True.
--slack-url SLACK_URL
URL for sending notifications to Slack. Optional.
--log-level LOG_LEVEL
Log level.
-bk BLOCKHEIGHT_KEY, --blockheight-key BLOCKHEIGHT_KEY
JSON key to extract the blockheight information, e.g., 'result.sync_info.latest_block_height'. The script will check if the blockheight at
this path is increasing.
--dry-run Executes a dry run without making actual HTTP requests. Default is False.
This script provides various options to check the HTTP status of URLs.
Usage examples:
1. Basic usage:
pawns http https://example.com
2. Verbose mode:
pawns http https://example.com -v
3. Using custom headers and POST method:
pawns http https://example.com -m POST --headers '{"Content-Type": "application/json"}' --data '{"param": "value"}'
4. Ignoring SSL verification and setting a custom timeout:
pawns http https://example.com --ignore-ssl True --timeout 5
5. Checking with specific success criteria and logical operator:
pawns http https://example.com --success 'status_code==200' 'response_time<2' --logical-operator and
6. Running with a custom config file and interval:
pawns http https://example.com -c http_config.ini -i 3
http_config.ini
[default]
success = status_code==200
slack_url =
interval = 3
method = get
; data = sdsd
data = {"sdsd": "sd222sd"}
[post]
url = http://httpbin.org/post
method = post
[http_200_ok]
url = http://httpbin.org/status/200
success = status_code==200
[http_300_ok_and_2ms_time]
url = http://httpbin.org/status/300
success = ['status_code==300', 'response_time<0.02']
[http_400_ok]
url = http://httpbin.org/status/400
success = ["status_code==400"]
7. Setting maximum workers and stack limit:
pawns http https://example.com -w 5 --stack-limit 10
8. Dry run without actual HTTP request:
pawns http https://example.com --dry-run
9. Sending notifications to a Slack URL on failure:
pawns http https://example.com --slack-url 'https://hooks.slack.com/services/...'
10. Checking blockheight increase:
pawns http http://test-node-01:26657/status --blockheight-key "result.sync_info.latest_block_height" -i 5
Officially supports Python 3.9+.
