Today, we have integrated a BFS crawler and HTML extraction. At present, the function still has limitations. Extract the body, see http://www.fuxiang90.me/2012/02/%E6%8A%BD%E5%8F%96html-%E6%AD%A3%E6%96%87/ Currently, only the URLs of the HTTP protocol are allowed to be crawled and tested only on the Intranet, because the connection to the Internet is not unpleasant. A global URL queue and URL set. The queue is for the convenience of BFS implementa

the combination of the two above, you can achieve intelligent control over shell multi-process. The purpose of Intelligent Data determination is to find that the speed bottleneck during script debugging is the curl speed, that is, the network speed. Therefore, once the script is interrupted due to an exception, repeat the curl operation, which greatly increases the script execution time. Therefore, through intelligent determination, the problem of curl time consumption and repeated data collect
