### What problem does this PR solve?
When the original code terminates the parsing task halfway, the progress
may not be 0 or 1, which will result in the inability to call the
interface to parse again
-Change the document parsing progress check to task status check, and
use TaskStatus.RUNNING.value to judge
-Update the condition judgment for stopping parsing documents, and check
whether the task is running instead
