salt.modules.http¶

Module for making various web calls. Primarily designed for webhooks and the like, but also useful for basic http testing.

salt.modules.http.query(url, **kwargs)¶

New in version 2015.5.0.

Query a resource, and decode the return data.

All keyword arguments are forwarded to salt.utils.http.query(). The most commonly used kwargs are summarized below; see the underlying utility for the full reference.

Request

method (default GET), params (query string dict), data (request body string), data_file (path or salt:// URL to read body from), data_render / data_renderer to render the body through a Salt renderer, template_dict of values to expose when rendering.

Headers

header_dict (dict of headers), header_list (list of Name: value strings), header_file (path or salt:// URL), header_render / header_renderer to render headers through a Salt renderer.

Authentication

username and password for HTTP basic auth, auth for a pre-built (user, pass) tuple, cert for a client certificate path or (cert, key) pair.

TLS

verify_ssl (default True), ca_bundle to point at an alternate CA bundle. Set verify_ssl=False only for trusted development endpoints.

Cookies and sessions

cookies to send a cookie jar, cookie_jar to load/save the jar from disk, cookie_format (lwp or mozilla), persist_session and session_cookie_jar to persist a session across calls.

Response decoding

decode (default False) parses the response body using decode_type (auto, json, yaml, xml or plain). decode_body (default True) controls whether to decode bytes to text at all. text returns the raw text body in the result, status returns the HTTP status code, headers returns response headers.

Streaming

stream (default False) streams the response body. streaming_callback and header_callback receive chunks as they arrive.

Output capture

text_out, headers_out and decode_out are paths to which the corresponding parts of the response will be written.

Form data

formdata (default False) sends a multipart/form-data body. formdata_fieldname and formdata_filename configure the file part.

Transport

backend (tornado, requests or urllib2), agent (User-Agent header), port (used when the URL has no explicit port), handle (default False) returns the raw backend response object.

Error handling

raise_error (default True). If False, connection errors are suppressed and the body of the return will simply be None.

Sensitive data

hide_fields is a list of header or form field names whose values should be redacted in the logged trace output.

Test mode

test (default False) and test_url allow you to dry-run the request against a fixture URL without making the real call.

CLI Example:

salt '*' http.query http://somelink.com/
salt '*' http.query http://somelink.com/ method=POST             params='{"key1": "val1", "key2": "val2"}'
salt '*' http.query http://somelink.com/ method=POST             data='<xml>somecontent</xml>'

salt.modules.http.update_ca_bundle(target=None, source=None, merge_files=None)¶

Update the local CA bundle file from a URL

New in version 2015.5.0.

CLI Example:

salt '*' http.update_ca_bundle
salt '*' http.update_ca_bundle target=/path/to/cacerts.pem
salt '*' http.update_ca_bundle source=https://example.com/cacerts.pem

If the target is not specified, it will be pulled from the ca_cert configuration variable available to the minion. If it cannot be found there, it will be placed at <<FILE_ROOTS>>/cacerts.pem.

If the source is not specified, it will be pulled from the ca_cert_url configuration variable available to the minion. If it cannot be found, it will be downloaded from the cURL website, using an http (not https) URL. USING THE DEFAULT URL SHOULD BE AVOIDED!

merge_files may also be specified, which includes a string or list of strings representing a file or files to be appended to the end of the CA bundle, once it is downloaded.

CLI Example:

salt '*' http.update_ca_bundle merge_files=/path/to/mycert.pem

salt.modules.http.wait_for_successful_query(url, wait_for=300, **kwargs)¶

Query a resource until a successful response, and decode the return data

CLI Example:

salt '*' http.wait_for_successful_query http://somelink.com/ wait_for=160 request_interval=1
