parameter (I .e., the parameter with the direction of in), so that the crawler will try to call the idenumerator method again, each time, the last Id obtained after the last call is passed as a parameter. In the implementation code of the idenumerator method, you can retrieve the data item ID after the ID from the external content source based on the input parameter. The crawler will try this method to repeatedly call the idenumerator method until

A small web site for online analysis was made with the recently-made claims applicant test data set.Data structures, algorithms and other settings are stored in the JSON file. In the future to this little broken station expansion algorithm, just modify the JSON file on the line.Of course, the result analysis still has to add the code. The page code is not affixed, after figuring out the Django View+model mo
