`AtomService provides CRUD ops. in line with the Atom Publishing Protocol.
AtomService: Encapsulates the ability to perform insert, update and delete
operations with the Atom Publishing Protocol on which GData is
based. An instance can perform query, insertion, deletion, and
update.
HttpRequest: Function that performs a GET, POST, PUT, or DELETE HTTP request
to the specified end point. An AtomService object or a subclass can be
used to specify information about the request.`

`` | `Performs Atom Publishing Protocol CRUD operations. The AtomService contains methods to perform HTTP CRUD operations.`
| Methods defined here: Delete(self, uri, extra_headers=None, url_params=None, escape_params=True) `Deletes the entry at the given URI. Args: uri: string The URI of the entry to be deleted. Example: '/base/feeds/items/ITEM-ID' extra_headers: dict (optional) HTTP headers which are to be included. The client automatically sets the Content-Type and Authorization headers. url_params: dict (optional) Additional URL parameters to be included in the URI. These are translated into query arguments in the form '&dict_key=value&...'. Example: {'max-results': '250'} becomes &max-results=250 escape_params: boolean (optional) If false, the calling code has already ensured that the query will form a valid URL (all reserved characters have been escaped). If true, this method will escape the query and any URL parameters provided. Returns: httplib.HTTPResponse Server's response to the DELETE request.` Get(self, uri, extra_headers=None, url_params=None, escape_params=True) `Query the APP server with the given URI The uri is the portion of the URI after the server value (server example: 'www.google.com'). Example use: To perform a query against Google Base, set the server to 'base.google.com' and set the uri to '/base/feeds/...', where ... is your query. For example, to find snippets for all digital cameras uri should be set to: '/base/feeds/snippets?bq=digital+camera' Args: uri: string The query in the form of a URI. Example: '/base/feeds/snippets?bq=digital+camera'. extra_headers: dicty (optional) Extra HTTP headers to be included in the GET request. These headers are in addition to those stored in the client's additional_headers property. The client automatically sets the Content-Type and Authorization headers. url_params: dict (optional) Additional URL parameters to be included in the query. These are translated into query arguments in the form '&dict_key=value&...'. Example: {'max-results': '250'} becomes &max-results=250 escape_params: boolean (optional) If false, the calling code has already ensured that the query will form a valid URL (all reserved characters have been escaped). If true, this method will escape the query and any URL parameters provided. Returns: httplib.HTTPResponse The server's response to the GET request.` Post(self, data, uri, extra_headers=None, url_params=None, escape_params=True, content_type='application/atom+xml') `Insert data into an APP server at the given URI. Args: data: string, ElementTree._Element, or something with a __str__ method The XML to be sent to the uri. uri: string The location (feed) to which the data should be inserted. Example: '/base/feeds/items'. extra_headers: dict (optional) HTTP headers which are to be included. The client automatically sets the Content-Type, Authorization, and Content-Length headers. url_params: dict (optional) Additional URL parameters to be included in the URI. These are translated into query arguments in the form '&dict_key=value&...'. Example: {'max-results': '250'} becomes &max-results=250 escape_params: boolean (optional) If false, the calling code has already ensured that the query will form a valid URL (all reserved characters have been escaped). If true, this method will escape the query and any URL parameters provided. Returns: httplib.HTTPResponse Server's response to the POST request.` Put(self, data, uri, extra_headers=None, url_params=None, escape_params=True, content_type='application/atom+xml') `Updates an entry at the given URI. Args: data: string, ElementTree._Element, or xml_wrapper.ElementWrapper The XML containing the updated data. uri: string A URI indicating entry to which the update will be applied. Example: '/base/feeds/items/ITEM-ID' extra_headers: dict (optional) HTTP headers which are to be included. The client automatically sets the Content-Type, Authorization, and Content-Length headers. url_params: dict (optional) Additional URL parameters to be included in the URI.

If true, this method will escape the query and any URL parameters provided. Returns: httplib.HTTPResponse Server's response to the PUT request.` UseBasicAuth(self, username, password, for_proxy=False) `Sets an Authenticaiton: Basic HTTP header containing plaintext.

Functions
`` |  | BuildUri(uri, url_params=None, escape_params=True) `Converts a uri string and a collection of parameters into a URI. This function is deprcated, use atom.url.Url instead. Args: uri: string url_params: dict (optional) escape_params: boolean (optional) uri: string The start of the desired URI. This string can alrady contain URL parameters. Examples: '/base/feeds/snippets', '/base/feeds/snippets?bq=digital+camera' url_parameters: dict (optional) Additional URL parameters to be included in the query. These are translated into query arguments in the form '&dict_key=value&...'. Example: {'max-results': '250'} becomes &max-results=250 escape_params: boolean (optional) If false, the calling code has already ensured that the query will form a valid URL (all reserved characters have been escaped). If true, this method will escape the query and any URL parameters provided. Returns: string The URI consisting of the escaped URL parameters appended to the initial uri string.` CalculateDataLength(data) `Attempts to determine the length of the data to send. This method will respond with a length only if the data is a string or and ElementTree element. Args: data: object If this is not a string or ElementTree element this funtion will return None.` DictionaryToParamList(url_parameters, escape_params=True) `Convert a dictionary of URL arguments into a URL parameter string. This function is deprcated, use atom.url.Url instead. Args: url_parameters: The dictionaty of key-value pairs which will be converted into URL parameters. For example, {'dry-run': 'true', 'foo': 'bar'} will become ['dry-run=true', 'foo=bar']. Returns: A list which contains a string for each key-value pair. The strings are ready to be incorporated into a URL by using '&'.join([] + parameter_list)` HttpRequest(service, operation, data, uri, extra_headers=None, url_params=None, escape_params=True, content_type='application/atom+xml') `Performs an HTTP call to the server, supports GET, POST, PUT, and DELETE. This method is deprecated, use atom.http.HttpClient.request instead. Usage example, perform and HTTP GET on http://www.google.com/: import atom.service client = atom.service.AtomService() http_response = client.Get('http://www.google.com/') or you could set the client.server to 'www.google.com' and use the following: client.server = 'www.google.com' http_response = client.Get('/') Args: service: atom.AtomService object which contains some of the parameters needed to make the request. The following members are used to construct the HTTP call: server (str), additional_headers (dict), port (int), and ssl (bool). operation: str The HTTP operation to be performed. This is usually one of 'GET', 'POST', 'PUT', or 'DELETE' data: ElementTree, filestream, list of parts, or other object which can be converted to a string. Should be set to None when performing a GET or PUT. If data is a file-like object which can be read, this method will read a chunk of 100K bytes at a time and send them. If the data is a list of parts to be sent, each part will be evaluated and sent. uri: The beginning of the URL to which the request should be sent. Examples: '/', '/base/feeds/snippets', '/m8/feeds/contacts/default/base' extra_headers: dict of strings. HTTP headers which should be sent in the request. These headers are in addition to those stored in service.additional_headers. url_params: dict of strings. Key value pairs to be added to the URL as URL parameters. For example {'foo':'bar', 'test':'param'} will become ?foo=bar&test=param. escape_params: bool default True. If true, the keys and values in url_params will be URL escaped when the form is constructed (Special characters converted to %XX form.) content_type: str The MIME type for the data being sent. Defaults to 'application/atom+xml', this is only used if data is set.` PrepareConnection(service, full_uri) `Opens a connection to the server based on the full URI. This method is deprecated, instead use atom.http.HttpClient.request. Examines the target URI and the proxy settings, which are set as environment variables, to open a connection with the server. This connection is used to make an HTTP request. Args: service: atom.AtomService or a subclass. It must have a server string which represents the server host to which the request should be made. It may also have a dictionary of additional_headers to send in the HTTP request. full_uri: str Which is the target relative (lacks protocol and host) or absolute URL to be opened. Example: 'https://www.google.com/accounts/ClientLogin' or 'base/feeds/snippets' where the server is set to www.google.com. Returns: A tuple containing the httplib.HTTPConnection and the full_uri for the request.` ProcessUrl(service, url, for_proxy=False) `Processes a passed URL. If the URL does not begin with https?, then the default value for server is used This method is deprecated, use atom.url.parse_url instead.` UseBasicAuth(service, username, password, for_proxy=False) `Sets an Authenticaiton: Basic HTTP header containing plaintext. Deprecated, use AtomService.use_basic_auth insread. The username and password are base64 encoded and added to an HTTP header which will be included in each request. Note that your username and password are sent in plaintext. The auth header is added to the additional_headers dictionary in the service object. Args: service: atom.AtomService or a subclass which has an additional_headers dict as a member. username: str password: str` deprecation(message)
