convert_json_to_ros_message()

def rospy_message_converter.json_message_converter.convert_json_to_ros_message	(		message_type,
			json_message,
			strict_mode = True,
			log_level = 'error'
	)

Takes in the message type and a JSON-formatted string and returns a ROS
message.

:param message_type: The desired ROS message type of the result
:type  message_type: str
:param json_message: A JSON-formatted string
:type  json_message: str
:param strict_mode: If strict_mode is set, an exception will be thrown if the json message contains extra fields.
:type  strict_mode: bool, optional
:param log_level: The log level to be used. Available levels: debug, info, warning, error, critical
:type  log_level: str, optional
:return: A ROS message
:rtype: class:`genpy.Message`

Example:
    >>> msg_type = "std_msgs/String"
    >>> json_msg = '{"data": "Hello, Robot"}'
    >>> convert_json_to_ros_message(msg_type, json_msg)
    data: "Hello, Robot"

convert_ros_message_to_json()

def rospy_message_converter.json_message_converter.convert_ros_message_to_json	(		message,
			binary_array_as_bytes = True
	)

Takes in a ROS message and returns a JSON-formatted string.

:param message: A ROS message to convert
:type  message: class:`genpy.Message`
:param binary_array_as_bytes: rospy treats `uint8[]` data as a `bytes`, which is the Python representation for byte
       data. In Python 2, this is the same as `str`. If this parameter is `False`, all `uint8[]` fields will be
       converted to `list(int)` instead.
:type  binary_array_as_bytes: bool, optional
:return: A JSON-formatted string
:rtype:  str

Example:
    >>> import std_msgs.msg
    >>> ros_message = std_msgs.msg.String(data="Hello, Robot")
    >>> convert_ros_message_to_json(ros_message)
    '{"data": "Hello, Robot"}'
