API¶
This section provides detailed information about the ligo.gracedb.rest.GraceDb
client class which is the primary method for accessing the GraceDB API.
-
class
ligo.gracedb.rest.
GraceDb
(service_url='https://gracedb.ligo.org/api/', cred=None, force_noauth=False, fail_if_noauth=False, api_version=None, reload_certificate=False, reload_buffer=300, use_auth='all', retries=5, retry_codes=[500, 502, 503, 504, 408, 409], backoff_factor=0.1)¶ GraceDb REST client class.
Provides a client object for accessing the GraceDB server API. Various methods are provided for retrieving information about different objects and uploading information.
Lookup of user credentials is done in the following order:
- If provided, import X.509 credentials from the certificate-key pair or combined proxy file provided in the
cred
keyword arg. - If the
X509_USER_CERT
andX509_USER_KEY
environment variables are set, load the corresponding certificate and key. - If the
X509_USER_PROXY
environment variable is set, load the corresponding proxy file. - Look for a X.509 proxy from ligo-proxy-init in the default location (
/tmp/x509up_u${UID}
). - Look for a certificate and key file in
$HOME/.globus/usercert.pem
and$HOME/.globus/userkey.pem
. - Continue with no authentication credentials.
Parameters: - url (
str
, optional) – URL of server API root. - cred (
tuple
orstr
, optional) – a tuple or list of (/path/to/cert/file
,/path/to/key/file
) or a single path to a combined proxy file. Used for X.509 authentication only. - reload_certificate (
bool
, optional) – if True, your certificate will be checked before each request whether it is withinreload_buffer
seconds of expiration, and if so, it will be reloaded. Useful for processes which may live longer than the certificate lifetime and have an automated method for certificate renewal. The path to the new/renewed certificate must be the same as for the old certificate. - reload_buffer (
int
, optional) – buffer (in seconds) for reloading a certificate in advance of its expiration. Only used ifreload_certificate
isTrue
. - retries (
int
, optional) – the maximum number of retries to attempt on an error from the server. Default 5. - backoff_factor (
float
, optional) – The backoff factor for retrying. Default: 0.1. Refer to urllib3 documentation for usage. - retry_codes (
list
, optional) – List of HTTPError codes to retry on. Default: [500, 502, 503, 504, 408, 409].
Examples
Instantiate a client to use the production GraceDB server:
>>> g = GraceDb()
/se another GraceDB server:
>>> g = GraceDb(service_url='https://gracedb-playground.ligo.org/api/')
Use a certificate and key in the non-default location:
>>> g = GraceDb(cred=('/path/to/cert/file', '/path/to/key/file'))
