azure.core.settings

Provide access to settings for globally used Azure configuration values.

class azure.core.settings.Settings[source]

Settings for globally used Azure configuration values.

You probably don’t want to create an instance of this class, but call the singleton instance:

from azure.common.settings import settings
settings.log_level = log_level = logging.DEBUG

The following methods are searched in order for a setting:

4. immediate values 3. previously user-set value 2. environment variable 1. system setting 0. implicit default

An implicit default is (optionally) defined by the setting attribute itself.

A system setting value can be obtained from registries or other OS configuration for settings that support that method.

An environment variable value is obtained from os.environ

User-set values many be specified by assigning to the attribute:

settings.log_level = log_level = logging.DEBUG

Immediate values are (optionally) provided when the setting is retrieved:

settings.log_level(logging.DEBUG())

Immediate values are most often useful to provide from optional arguments to client functions. If the argument value is not None, it will be returned as-is. Otherwise, the setting searches other methods according to the precedence rules.

Immutable configuration snapshots can be created with the following methods:

  • settings.defaults returns the base defaultsvalues , ignoring any environment or system or user settings

  • settings.current returns the current computation of settings including prioritizatiom of configuration sources, unless defaults_only is set to True (in which case the result is identical to settings.defaults)

  • settings.config can be called with specific values to override what settings.current would provide

# return current settings with log level overridden
settings.config(log_level=logging.DEBUG)
Variables

  • log_level – a log level to use across all Azure client SDKs (AZURE_LOG_LEVEL)

  • tracing_enabled – Whether tracing should be enabled across Azure SDKs (AZURE_TRACING_ENABLED)

  • tracing_implementation – The tracing implementation to use (AZURE_SDK_TRACING_IMPLEMENTATION)

Example

>>> import logging
>>> from azure.core.settings import settings
>>> settings.log_level = logging.DEBUG
>>> settings.log_level()
10

>>> settings.log_level(logging.WARN)
30
config(**kwargs)[source]

Return the currently computed settings, with values overridden by parameter values.

Examples:

# return current settings with log level overridden
settings.config(log_level=logging.DEBUG)
property current

Return the current values for all settings.

Return type

namedtuple

property defaults

Return implicit default values for all settings, ignoring environment and system.

Return type

namedtuple

property defaults_only

Whether to ignore environment and system settings and return only base default values.

Return type

bool

log_level

Return a value for a global setting according to configuration precedence.

The following methods are searched in order for the setting:

4. immediate values 3. previously user-set value 2. environment variable 1. system setting 0. implicit default

If a value cannot be determined, a RuntimeError is raised.

The env_var argument specifies the name of an environment to check for setting values, e.g. "AZURE_LOG_LEVEL".

The optional system_hook can be used to specify a function that will attempt to look up a value for the setting from system-wide configurations.

The optional default argument specified an implicit default value for the setting that is returned if no other methods provide a value.

A convert agument may be provided to convert values before they are returned. For instance to concert log levels in environment variables to logging module values.

tracing_enabled

azure.core.serialization

class azure.core.serialization.AzureJSONEncoder(*, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan=True, sort_keys=False, indent=None, separators=None, default=None)[source]

A JSON encoder that’s capable of serializing datetime objects and bytes.

Constructor for JSONEncoder, with sensible defaults.

If skipkeys is false, then it is a TypeError to attempt encoding of keys that are not str, int, float or None. If skipkeys is True, such items are simply skipped.

If ensure_ascii is true, the output is guaranteed to be str objects with all incoming non-ASCII characters escaped. If ensure_ascii is false, the output can contain non-ASCII characters.

If check_circular is true, then lists, dicts, and custom encoded objects will be checked for circular references during encoding to prevent an infinite recursion (which would cause an OverflowError). Otherwise, no such check takes place.

If allow_nan is true, then NaN, Infinity, and -Infinity will be encoded as such. This behavior is not JSON specification compliant, but is consistent with most JavaScript based encoders and decoders. Otherwise, it will be a ValueError to encode such floats.

If sort_keys is true, then the output of dictionaries will be sorted by key; this is useful for regression tests to ensure that JSON serializations can be compared on a day-to-day basis.

If indent is a non-negative integer, then JSON array elements and object members will be pretty-printed with that indent level. An indent level of 0 will only insert newlines. None is the most compact representation.

If specified, separators should be an (item_separator, key_separator) tuple. The default is (‘, ‘, ‘: ‘) if indent is None and (‘,’, ‘: ‘) otherwise. To get the most compact JSON representation, you should specify (‘,’, ‘:’) to eliminate whitespace.

If specified, default is a function that gets called for objects that can’t otherwise be serialized. It should return a JSON encodable version of the object or raise a TypeError.

default(o)[source]

Implement this method in a subclass such that it returns a serializable object for o, or calls the base implementation (to raise a TypeError).

For example, to support arbitrary iterators, you could implement default like this:

def default(self, o):
    try:
        iterable = iter(o)
    except TypeError:
        pass
    else:
        return list(iterable)
    # Let the base class default method raise the TypeError
    return JSONEncoder.default(self, o)
encode(o)

Return a JSON string representation of a Python data structure.

>>> from json.encoder import JSONEncoder
>>> JSONEncoder().encode({"foo": ["bar", "baz"]})
'{"foo": ["bar", "baz"]}'
iterencode(o, _one_shot=False)

Encode the given object and yield each string representation as available.

For example:

for chunk in JSONEncoder().iterencode(bigobject):
    mysocket.write(chunk)
item_separator = ', '
key_separator = ': '
azure.core.serialization.NULL = <azure.core.serialization._Null object>

A falsy sentinel object which is supposed to be used to specify attributes with no data. This gets serialized to null on the wire.

An HTTP request.

It should be passed to your client’s send_request method.

>>> from azure.core.rest import HttpRequest
>>> request = HttpRequest('GET', 'http://www.example.com')
<HttpRequest [GET], url: 'http://www.example.com'>
>>> response = client.send_request(request)

Parameters

  • method (str) – HTTP method (GET, HEAD, etc.)

  • url (str) – The url for your request

Keyword Arguments

  • params (mapping) – Query parameters to be mapped into your URL. Your input should be a mapping of query name to query value(s).

  • headers (mapping) – HTTP headers you want in your request. Your input should be a mapping of header name to header value.

  • json (any) – A JSON serializable object. We handle JSON-serialization for your object, so use this for more complicated data structures than data.

  • content (str or bytes or iterable[bytes] or asynciterable[bytes]) – Content you want in your request body. Think of it as the kwarg you should input if your data doesn’t fit into json, data, or files. Accepts a bytes type, or a generator that yields bytes.

  • data (dict) – Form data you want in your request body. Use for form-encoded data, i.e. HTML forms.

  • files (mapping) – Files you want to in your request body. Use for uploading files with multipart encoding. Your input should be a mapping of file name to file content. Use the data kwarg in addition if you want to include non-file data files as part of your request.
