onError method
The callback will be executed on error.
If you want to continue the error , call handler.next
.
If you want to complete the response with some custom data directly,
you can resolve a Response
object with handler.resolve
and other
error interceptor(s) will be skipped.
If you want to complete the response with an error message directly,
you can reject a DioError
object with handler.reject
, and other
error interceptor(s) will be skipped.
Implementation
@override
onError(DioError err, ErrorInterceptorHandler handler) async {
AppConfig.printLog('请求异常: ' + err.toString());
AppConfig.printLog('请求异常信息: ' + (err.response ?? '').toString());
return super.onError(err, handler);
}
