Methodendetails

throwFacebookResponseStatusExceptionIfNecessary

void throwFacebookResponseStatusExceptionIfNecessary(String json,
 Integer httpStatusCode)

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.

Parameter:

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

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

Löst aus:

FacebookGraphException - If the JSON contains a Graph API error response.

FacebookResponseStatusException - If the JSON contains an Legacy API error response.

FacebookJsonMappingException - If an error occurs while processing the JSON.

throwBatchFacebookResponseStatusExceptionIfNecessary

void throwBatchFacebookResponseStatusExceptionIfNecessary(String json,
 Integer httpStatusCode)

If the error and error_description JSON fields are present, we've got a response status error for this batch API call. Extracts relevant information from the JSON and throws an exception which encapsulates it for end-user consumption.

Parameter:

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

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

Löst aus:

FacebookResponseStatusException - If the JSON contains an error code.

FacebookJsonMappingException - If an error occurs while processing the JSON.
