After you are done with the class, + always call the Finalize function at + the end. + This class supports either OAuth protocol versions 1.0, 1.0a and + 2.0. It abstracts the differences between these protocol versions, + so the class usage is the same independently of the OAuth + version of the server. + The class also provides built-in support to several popular OAuth + servers, so you do not have to manually configure all the details to + access those servers. Just set the + server variable to configure the class + to access one of the built-in supported servers. + If you need to access one type of server that is not yet directly + supported by the class, you need to configure it explicitly setting + the variables: oauth_version, + url_parameters, + authorization_header, + request_token_url, + dialog_url, + offline_dialog_url, + append_state_to_redirect_uri and + access_token_url. + Before proceeding to the actual OAuth authorization process, you + need to have registered your application with the OAuth server. The + registration provides you values to set the variables + client_id and + client_secret. + You also need to set the variables + redirect_uri and + scope before calling the + Process function to make the class + perform the necessary interactions with the OAuth + server. + The OAuth protocol involves multiple steps that include redirection + to the OAuth server. There it asks permission to the current user to + grant your application access to APIs on his/her behalf. When there + is a redirection, the class will set the + exit variable to + 1. Then your script should exit + immediately without outputting anything. + When the OAuth access token is successfully obtained, the following + variables are set by the class with the obtained values: + access_token, + access_token_secret, + access_token_expiry, + access_token_type. You may want to + store these values to use them later when calling the server + APIs. + If there was a problem during OAuth authorization process, check the + variable authorization_error to + determine the reason. + Once you get the access token, you can call the server APIs using + the CallAPI function. Check the + access_token_error variable to + determine if there was an error when trying to to call the + API. + If for some reason the user has revoked the access to your + application, you need to ask the user to authorize your application + again. First you may need to call the function + ResetAccessToken to reset the value of + the access token that may be cached in session variables. + + +{/metadocument} +*/ + +class oauth_client_class +{ +/* +{metadocument} + + error + STRING + + + Store the message that is returned when an error + occurs. + Check this variable to understand what happened when a call to + any of the class functions has failed. + This class uses cumulative error handling.

      +

      Purpose

      +

      This class serves two main purposes:

      +

      1) Implement the OAuth protocol to retrieve a token from a server to authorize the access to an API on behalf of the current user.

      +

      2) Perform calls to a Web services API using a token previously obtained using this class or a token provided some other way by the Web services provider.

      +

      Usage

      +

      Regardless of your purposes, you always need to start calling the class Initialize function after initializing setup variables. After you are done with the class, always call the Finalize function at the end.

      +

      This class supports either OAuth protocol versions 1.0, 1.0a and 2.0. It abstracts the differences between these protocol versions, so the class usage is the same independently of the OAuth version of the server.

      +

      The class also provides built-in support to several popular OAuth servers, so you do not have to manually configure all the details to access those servers. Just set the server variable to configure the class to access one of the built-in supported servers.

      +

      If you need to access one type of server that is not yet directly supported by the class, you need to configure it explicitly setting the variables: oauth_version, url_parameters, authorization_header, request_token_url, dialog_url, offline_dialog_url, append_state_to_redirect_uri and access_token_url.

      +

      Before proceeding to the actual OAuth authorization process, you need to have registered your application with the OAuth server. The registration provides you values to set the variables client_id and client_secret.

      +

      You also need to set the variables redirect_uri and scope before calling the Process function to make the class perform the necessary interactions with the OAuth server.

      +

      The OAuth protocol involves multiple steps that include redirection to the OAuth server. There it asks permission to the current user to grant your application access to APIs on his/her behalf. When there is a redirection, the class will set the exit variable to 1. Then your script should exit immediately without outputting anything.

      +

      When the OAuth access token is successfully obtained, the following variables are set by the class with the obtained values: access_token, access_token_secret, access_token_expiry, access_token_type. You may want to store these values to use them later when calling the server APIs.

      +

      If there was a problem during OAuth authorization process, check the variable authorization_error to determine the reason.

      +

      Once you get the access token, you can call the server APIs using the CallAPI function. Check the access_token_error variable to determine if there was an error when trying to to call the API.

      +

      If for some reason the user has revoked the access to your application, you need to ask the user to authorize your application again. First you may need to call the function ResetAccessToken to reset the value of the access token that may be cached in session variables.

      Type

      +

      string

      +

      Default value

      +

      ''

      +

      Purpose

      +

      Store the message that is returned when an error occurs.

      +

      Usage

      +

      Check this variable to understand what happened when a call to any of the class functions has failed.

      +

      This class uses cumulative error handling. This means that if one class functions that may fail is called and this variable was already set to an error message due to a failure in a previous call to the same or other function, the function will also fail and does not do anything.

      +

      This allows programs using this class to safely call several functions that may fail and only check the failure condition after the last function call.

      +

      Just set this variable to an empty string to clear the error condition.

      Purpose

      +

      Identify the type of OAuth server to access.

      +

      Usage

      +

      The class provides built-in support to several types of OAuth servers. This means that the class can automatically initialize several configuration variables just by setting this server variable.

      +

      Currently it supports the following servers: 'Bitbucket', 'Box', 'Dropbox', 'Eventful', 'Facebook', 'Fitbit', 'Flickr', 'Foursquare', 'github', 'Google', 'Instagram', 'LinkedIn', 'Microsoft', 'Scoop.it', 'StockTwits', 'Tumblr', 'Twitter', 'XING' and 'Yahoo'. Please contact the author if you would like to ask to add built-in support for other types of OAuth servers.

      +

      If you want to access other types of OAuth servers that are not yet supported, set this variable to an empty string and configure other variables with values specific to those servers.

      +

      Variables

      +

      +

      Usage

      +

      Set this variable to the OAuth request token URL when you are not accessing one of the built-in supported OAuth servers.

      +

      For certain servers, the dialog URL can have certain marks that will act as template placeholders which will be replaced with values defined before redirecting the users browser. Currently it supports the following placeholder marks:

      +

      {REDIRECT_URI} - URL to redirect when returning from the OAuth server authorization page

      +

      {CLIENT_ID} - client application identifier registered at the server

      Store the values of the access token when it is succefully retrieved from the OAuth server.

      +

      Usage

      +

      This function is meant to be only be called from inside the class. By default it stores access tokens in a session variable named 'OAUTH_ACCESS_TOKEN'.

      +

      Actual implementations should create a sub-class and override this function to make the access token values be stored in other types of containers, like for instance databases.

      +

      Arguments

      +
        +

        access_token - Associative array with properties of the access token. The array may have set the following properties:

        +

        'value': string value of the access token

        +

        'authorized': boolean value that determines if the access token was obtained successfully

        +

        'expiry': (optional) timestamp in ISO format relative to UTC time zone of the access token expiry time

        +

        'type': (optional) type of OAuth token that may determine how it should be used when sending API call requests.

        +

        'refresh': (optional) token that some servers may set to allowing refreshing access tokens when they expire.

        +
      +

      Return value

      +

      This function should return 1 if the access token was stored successfully.

      +

      Functions

      +

    • GetAccessToken

      • +

      Synopsis

      +

      bool GetAccessToken(

      +)

      +

      Purpose

      +

      Retrieve the OAuth access token if it was already previously stored by the StoreAccessToken function.

      +

      Usage

      +

      This function is meant to be only be called from inside the class. By default it retrieves access tokens stored in a session variable named 'OAUTH_ACCESS_TOKEN'.

      +

      Actual implementations should create a sub-class and override this function to retrieve the access token values from other types of containers, like for instance databases.

      +

      Arguments

      +
        +

        access_token - Return the properties of the access token in an associative array. If the access token was not yet stored, it returns an empty array. Otherwise, the properties it may return are the same that may be passed to the StoreAccessToken.

        +
      +

      Return value

      +

      This function should return 1 if the access token was retrieved successfully.

      +

      Functions

      +

    • ResetAccessToken

      • +

      Synopsis

      +

      bool ResetAccessToken()

      +

      Purpose

      +

      Reset the access token to a state back when the user has not yet authorized the access to the OAuth server API.

      +

      Usage

      +

      Call this function if for some reason the token to access the API was revoked and you need to ask the user to authorize the access again.

      +

      By default the class stores and retrieves access tokens in a session variable named 'OAUTH_ACCESS_TOKEN'.

      +

      This function must be called when the user is accessing your site pages, so it can reset the information stored in session variables that cache the state of a previously retrieved access token.

      +

      Actual implementations should create a sub-class and override this function to reset the access token state when it is stored in other types of containers, like for instance databases.

      +

      Return value

      +

      This function should return 1 if the access token was resetted successfully.

      Purpose

      +

      Send a HTTP request to the Web services API using a previously obtained authorization token via OAuth.

      +

      Usage

      +

      This function can be used to call an API after having previously obtained an access token through the OAuth protocol using the Process function, or by directly setting the variables access_token, as well as access_token_secret in case of using OAuth 1.0 or 1.0a services.

      +

      Arguments

      +
        +

        url - URL of the API where the HTTP request will be sent.

        +

        parameters - Associative array with the names and values of the API call request parameters.

        +

        options - Associative array with additional options to configure the request. Currently it supports the following options:

        +

        '2Legged': boolean option that determines if the API request should be 2 legged. The default value is 0.

        +

        'Accept': content type value of the Accept HTTP header to be sent in the API call HTTP request. Some APIs require that a certain value be sent to specify which version of the API is being called. The default value is '*/*'.

        +

        'ConvertObjects': boolean option that determines if objects should be converted into arrays when the response is returned in JSON format. The default value is 0.

        +

        'FailOnAccessError': boolean option that determines if this functions should fail when the server response status is not between 200 and 299. The default value is 0.

        +

        'Files': associative array with details of the parameters that must be passed as file uploads. The array indexes must have the same name of the parameters to be sent as files. The respective array entry values must also be associative arrays with the parameters for each file. Currently it supports the following parameters:

        +

        - Type - defines how the parameter value should be treated. It can be 'FileName' if the parameter value is is the name of a local file to be uploaded. It may also be 'Data' if the parameter value is the actual data of the file to be uploaded.

        +

        - Default: 'FileName'

        +

        - ContentType - MIME value of the content type of the file. It can be 'automatic/name' if the content type should be determine from the file name extension.

        +

        - Default: 'automatic/name'

        +

        'PostValuesInURI': boolean option to determine that a POST request should pass the request values in the URI. The default value is 0.

        +

        'FollowRedirection': limit number of times that HTTP response redirects will be followed. If it is set to 0, redirection responses fail in error. The default value is 0.

        +

        'RequestBody': request body data of a custom type. The 'RequestContentType' option must be specified, so the 'RequestBody' option is considered.

        +

        'RequestContentType': content type that should be used to send the request values. It can be either 'application/x-www-form-urlencoded' for sending values like from Web forms, or 'application/json' for sending the values encoded in JSON format. Other types are accepted if the 'RequestBody' option is specified. The default value is 'application/x-www-form-urlencoded'.

        +

        'RequestBody': request body data of a custom type. The 'RequestContentType' option must be specified, so the 'RequestBody' option is considered.

        +

        'Resource': string with a label that will be used in the error messages and debug log entries to identify what operation the request is performing. The default value is 'API call'.

        +

        'ResponseContentType': content type that should be considered when decoding the API request response. This overrides the Content-Type header returned by the server. If the content type is 'application/x-www-form-urlencoded' the function will parse the data returning an array of key-value pairs. If the content type is 'application/json' the response will be decode as a JSON-encoded data type. Other content type values will make the function return the original response value as it was returned from the server. The default value for this option is to use what the server returned in the Content-Type header.

        +

        response - Return the value of the API response. If the value is JSON encoded, this function will decode it and return the value converted to respective types. If the value is form encoded, this function will decode the response and return it as an array. Otherwise, the class will return the value as a string.

        +
      +

      Return value

      +

      This function returns 1 if the call was done successfully.
