OAuth1 C Reference Documentation

OAuth1

Current Version: 10.1.2

OAuth 1.0a signature generator.

Create/Dispose

HCkOAuth1 instance = CkOAuth1_Create();
// ...
CkOAuth1_Dispose(instance);
HCkOAuth1 CkOAuth1_Create(void);

Creates an instance of the HCkOAuth1 object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.

void CkOAuth1_Dispose(HCkOAuth1 handle);

Objects created by calling CkOAuth1_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkOAuth1_Dispose.

Properties

AuthorizationHeader
void CkOAuth1_getAuthorizationHeader(HCkOAuth1 cHandle, HCkString retval);
const char *CkOAuth1_authorizationHeader(HCkOAuth1 cHandle);
Introduced in version 9.5.0.53

The authorization header. This is what would be included in the Authorization HTTP request header if it is going to be used as the means for providing the OAuth1 authorization information.

top
BaseString
void CkOAuth1_getBaseString(HCkOAuth1 cHandle, HCkString retval);
const char *CkOAuth1_baseString(HCkOAuth1 cHandle);
Introduced in version 9.5.0.53

This is the exact string that was signed. For example, if the signature method is HMAC-SHA1, the BaseString is the exact string that passed to the HMAC-SHA1. An application does not set the BaseString property. The BaseString is exposed as a property to allow for debugging and to see the exact string that is signed.

top
ConsumerKey
void CkOAuth1_getConsumerKey(HCkOAuth1 cHandle, HCkString retval);
void CkOAuth1_putConsumerKey(HCkOAuth1 cHandle, const char *newVal);
const char *CkOAuth1_consumerKey(HCkOAuth1 cHandle);
Introduced in version 9.5.0.53

The consumer key.

top
ConsumerSecret
void CkOAuth1_getConsumerSecret(HCkOAuth1 cHandle, HCkString retval);
void CkOAuth1_putConsumerSecret(HCkOAuth1 cHandle, const char *newVal);
const char *CkOAuth1_consumerSecret(HCkOAuth1 cHandle);
Introduced in version 9.5.0.53

The consumer secret.

top
DebugLogFilePath
void CkOAuth1_getDebugLogFilePath(HCkOAuth1 cHandle, HCkString retval);
void CkOAuth1_putDebugLogFilePath(HCkOAuth1 cHandle, const char *newVal);
const char *CkOAuth1_debugLogFilePath(HCkOAuth1 cHandle);

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.
