throwFacebookResponseStatusExceptionIfNecessary

public void throwFacebookResponseStatusExceptionIfNecessary(String json,
 Integer httpStatusCode)

Beschreibung aus Schnittstelle kopiert: FacebookExceptionGenerator

Throws an exception if Facebook returned an error response. Using the Graph API, it's possible to see both the new Graph API-style errors as well as Legacy API-style errors, so we have to handle both here. This method extracts relevant information from the error JSON and throws an exception which encapsulates it for end-user consumption.

For Graph API errors:

If the error JSON field is present, we've got a response status error for this API call.

For Legacy errors (e.g. FQL):

If the error_code JSON field is present, we've got a response status error for this API call.

Angegeben von:

json - The JSON returned by Facebook in response to an API call.

httpStatusCode - The HTTP status code returned by the server, e.g. 500.
