Create Session: create a HTTP session to a server

url Base url of the server

alias Robot Framework alias to identify the session

headers Dictionary of default headers

cookies Dictionary of cookies

client_certs [‘client certificate’, ‘client key’] PEM files containing the client key and certificate

timeout Connection timeout

proxies Dictionary that contains proxy urls for HTTP and HTTPS communication

verify Whether the SSL cert will be verified. A CA_BUNDLE path can also be provided.

Defaults to False.

debug Enable http verbosity option more information

https://docs.python.org/2/library/httplib.html#httplib.HTTPConnection.set_debuglevel

max_retries Number of maximum retries each connection should attempt.

By default it will retry 3 times in case of connection errors only. A 0 value will disable any kind of retries regardless of other retry settings. In case the number of retries is reached a retry exception is raised.

disable_warnings Disable requests warning useful when you have large number of testcases

backoff_factor Introduces a delay time between retries that is longer after each retry.

eg. if backoff_factor is set to 0.1 the sleep between attemps will be: 0.0, 0.2, 0.4 More info here: https://urllib3.readthedocs.io/en/latest/reference/urllib3.util.html

retry_method_list List of uppercased HTTP method verbs where retries are allowed.

By default retries are allowed only on HTTP requests methods that are considered to be idempotent (multiple requests with the same parameters end with the same state). eg. set to [‘POST’, ‘GET’] to retry only those kind of requests.

retry_status_list List of integer HTTP status codes that, if returned, a retry is attempted.

eg. set to [502, 503] to retry requests if those status are returned. Note that max_retries must be greater than 0.

delete_all_sessions()

Removes all the session objects

delete_request(alias, uri, data=None, json=None, params=None, headers=None, allow_redirects=None, timeout=None)

Send a DELETE request on the session object found using the given alias

alias that will be used to identify the Session object in the cache

uri to send the DELETE request to

json a value that will be json encoded

and sent as request data if data is not specified

headers a dictionary of headers to use with the request

allow_redirects Boolean. Set to True if POST/PUT/DELETE redirect following is allowed.

timeout connection timeout

download(url: str, target_file: str = None, binary: bool = True, verify: bool = True, force_new_session: bool = False, overwrite: bool = False) → dict

An alias for the HTTP Get keyword.

The difference in use is that the URL is always downloaded based on the URL path (even without target_file). If there is a filename in the path, then that is used as target_file to save to. By default, the filename will be “downloaded.html”.

url target URL for GET request

target_file filepath to save request content, default None

binary if file is saved as binary, default True

force_new_session if new HTTP session should be created, default False

overwrite used together with target_file, if True will overwrite the target file, default False

get_current_session_alias() → str

Get request session alias that was used with the HTTP Get keyword.

Return name of session alias.

static get_file_for_streaming_upload(path)

Opens and returns a file descriptor of a specified file to be passed as data parameter to other requests keywords.

This allows streaming upload of large files without reading them into memory.

File descriptor is binary mode and read only. Requests keywords will automatically close the file, if used outside this library it’s up to the caller to close it.

get_request(alias, uri, headers=None, data=None, json=None, params=None, allow_redirects=None, timeout=None)

Send a GET request on the session object found using the given alias

alias that will be used to identify the Session object in the cache

uri to send the GET request to

params url parameters to append to the uri

headers a dictionary of headers to use with the request

data a dictionary of key-value pairs that will be urlencoded

and sent as GET data or binary data that is sent as the raw body content

json a value that will be json encoded

and sent as GET data if data is not specified

allow_redirects Boolean. Set to True if POST/PUT/DELETE redirect following is allowed.

timeout connection timeout

head_request(alias, uri, headers=None, allow_redirects=None, timeout=None)

Send a HEAD request on the session object found using the given alias

alias that will be used to identify the Session object in the cache

uri to send the HEAD request to

allow_redirects Boolean. Set to True if POST/PUT/DELETE redirect following is allowed.

headers a dictionary of headers to use with the request

timeout connection timeout

http_get(url: str, target_file: str = None, binary: bool = True, verify: bool = True, force_new_session: bool = False, overwrite: bool = False) → dict

A helper method for Get Request that will create a session, perform GET request, and store the target file, if set by the target_file parameter.

The old session will be used if the URL scheme and the host are the same as previously, e.g., ‘https://www.google.fi’ part of the URL.

url target URL for GET request

target_file filepath to save request content, default None

binary if file is saved as binary, default True

verify if SSL verification should be done, default True

force_new_session if new HTTP session should be created, default False

overwrite used together with target_file, if True will overwrite the target file, default False

Returns request response.

options_request(alias, uri, headers=None, allow_redirects=None, timeout=None)

Send an OPTIONS request on the session object found using the given alias

request_should_be_successful(response)

session_exists(alias)

Return True if the session has been already created

alias that has been used to identify the Session object in the cache

status_should_be(expected_status, response, msg=None)

expected_status could be the code number as an integer or as string. But it could also be a named status code like ‘ok’, ‘created’, ‘accepted’ or ‘bad request’, ‘not found’ etc.

The response is the output of other requests keywords like Get Request.

A custom message msg can be added to work like built in keywords.
