Enumeration Type Documentation

enum QOAuth::ErrorCode

This error codes collection contains both network-related errors and those that can occur when incorrect arguments are provided to any of the class's methods.

See also:

QOAuth::Interface::error

Enumerator:

NoError	No error occured (so far :-) ).
BadRequest	Represents HTTP status code 400 (Bad Request).
Unauthorized	Represents HTTP status code 401 (Unauthorized).
Forbidden	Represents HTTP status code 403 (Forbidden).
Timeout	Represents a request timeout error.
ConsumerKeyEmpty	Consumer key has not been provided.
ConsumerSecretEmpty	Consumer secret has not been provided.
UnsupportedHttpMethod	The HTTP method is not supported by the request. Note that QOAuth::Interface::requestToken() and QOAuth::Interface::accessToken() accept only HTTP GET and POST requests.
RSAPrivateKeyEmpty	RSA private key has not been provided.
RSADecodingError	There was a problem decoding the RSA private key (the key is invalid or the provided passphrase is incorrect)
RSAKeyFileError	The provided key file either doesn't exist or is unreadable.
OtherError	A network-related error not specified above.

enum QOAuth::HttpMethod

The HTTP method has to be specified in QOAuth class for two reasons:

• to know what type of request should be prepared and sent (QOAuth::Interface::requestToken() and QOAuth::Interface::accessToken()),
• to prepare a correct signature, as the Signature Base String contains a parameter specifying the HTTP method used for request (QOAuth::Interface::createParametersString()).

Note:

For QOAuth::Interface::requestToken() and QOAuth::Interface::accessToken() methods only GET and POST methods are allowed.

Enumerator:

GET	Sets the HTTP method to GET.
POST	Sets the HTTP method to POST.
HEAD	Sets the HTTP method to HEAD.
PUT	Sets the HTTP method to PUT.
DELETE	Sets the HTTP method to DELETE.

enum QOAuth::ParsingMode

When creating a parameters string for a custom request using QOAuth::Interface::createParametersString() the parsing mode must be defined in order to prepare the string correctly.

According to what is stated in OAuth 1.0 Core specification, parameters can be passed in a request to the Service Provider in 3 different ways. When using QOAuth::Interface::createParametersString(), choose the one that suits you by setting ParsingMode appropriatelly.

See also:

QOAuth::Interface::createParametersString()

Enumerator:

ParseForRequestContent	Inline query format (foo=bar&bar=baz&baz=foo ...), suitable for POST requests.
ParseForInlineQuery	Same as ParseForRequestContent, but prepends the string with a question mark - suitable for GET requests (appending parameters to the request URL)
ParseForHeaderArguments	HTTP request header format (parameters to be put inside a request header).
ParseForSignatureBaseString	Signature Base String format, meant for internal use.

enum QOAuth::SignatureMethod

There are 3 different signature methods defined by the OAuth protocol. This enum is used to specify the method used by a specific request. Hence, one of its values must be passed as a parameter in any of the QOAuth::Interface::requestToken(), QOAuth::Interface::accessToken() or QOAuth::Interface::createParametersString() method.

Note:

The current implementation of the library supports only HMAC-SHA1 signature algorithm.

Enumerator:

HMAC_SHA1	Sets the signature method to HMAC-SHA1.
RSA_SHA1	Sets the signature method to RSA-SHA1 (not implemented yet).
PLAINTEXT	Sets the signature method to PLAINTEXT (not implemented yet).

QByteArray QOAuth::tokenParameterName

(

)

Useful when reading Service Provider's reply for QOAuth::Interface::accessToken() request, e.g:

      QOAuth::Interface qoauth;
      QByteArray requestToken = "token";
      QByteArray requestTokenSecret = "secret";
      QOAuth::ParamMap reply = qoauth.accessToken( "http://example.com/access_token", QOAuth::POST,
                          token, tokenSecret, QOAuth::HMAC_SHA1 );

      if ( qoauth.error() == QOAuth::NoError ) {
        token = reply.value( QOAuth::tokenParameterName() );
        tokenSecret = reply.value( QOAuth::tokenSecretParameterName() );
      }
