bluesky_queueserver_api.http.aio.REManagerAPI

class bluesky_queueserver_api.http.aio.REManagerAPI(*, http_server_uri=None, http_auth_provider=None, timeout=5.0, timeout_login=60.0, console_monitor_poll_period=0.5, console_monitor_max_msgs=10000, console_monitor_max_lines=1000, request_fail_exceptions=True, status_expiration_period=0.5, status_polling_period=1.0)

API for communication with RE Manager using HTTP (RESTful API) protocol.

Parameters:

http_server_uri: str or None

URI of Bluesky HTTP Server. If None, then the default URI “http://localhost:60610”` is used.

http_auth_provider: str or None, optional

Name of the endpoint of authentication provider (such as '/toy/token') or None if authentication provider is not needed (e.g. if authorization using API keys is used). The provider may also be passed as a parameter of login API if needed. Default: None.

timeout: float, optional

Request timeout. Positive value sets timeout in seconds, 0 (zero) disables timeouts, None sets timeout to the default value. Default value is 5.0 seconds.

timeout_login: float, optional

Request timeout used for login requests. Login requests may take substantial time to process at the server, especially in case of 2FA. See the description for the parameter timeout for more information. Default value is 60.0 seconds.

console_monitor_poll_period: float

Polling period defines interval between consecutive HTTP requests to the server. Default: 0.5 s.

console_monitor_max_msgs: int

Maximum number of messages in the internal message buffer. Default: 10000.

console_monitor_max_lines: int

Maximum number of lines in the internal text buffer. Default: 1000.

request_fail_exceptions: boolean

If True (default) then API functions that communicate with RE Manager are raising the RequestFailError exception if the request is rejected (the response contains "success": False, e.g. if a submitted plan is rejected). If False, then API functions are always returning the response and user code is responsible for checking and processing the success flag.

status_expiration_period: float

Expiration period for cached RE Manager status, default value: 0.5 seconds

status_polling_period: float

Polling period for RE Manager status used by ‘wait’ operations, default value: 1 second

Examples

Synchronous API:

from bluesky_queueserver_api.http import REManagerAPI
RM = REManagerAPI()
# < some useful code >
RE.close()

Asynchronous API:

from bluesky_queueserver_api.http.aio import REManagerAPI

async def testing():
    RM = REManagerAPI()
    # < some useful code >
    await RE.close()

asyncio.run(testing())
