| + | - [[projs:clans:docs:sps:handler.calc(source,target)]]: Return the shortest path from source company to target company based on a weighted people social network. | ||
| + | - [[projs:clans:docs:sps:handler.writejson(path)]]: Return a json file shown on the website about shortest path from person to person. | ||
| + | - [[projs:clans:docs:sps:handler.writejson(cid1,cid2,pathlist)]]: Returns a json file shown on the website. It is list of shortest path from source company to target company. | ||
| + | ====== Implementation ====== | ||
| + | - Main idea: | ||
| + | - - call initDataset() as long as the server running | ||
| + | - - after data is ready, call do_GET() function when receives an URL request. | ||
| + | - - In do_GET() function, the main idea is: extract source pid and target pid, then call Handler.calP(source,target) to get path list of pid, then call Handler.writejson(path) to generate json file. BaseHTTPRequestHandler.wfile.write(json file) to show result on browser. | ||
| + | - Add flow chat here | ||
