MongoDB批量上传代码

Question

以下上传方法应该批量上传到给定的MongoDB集合。它成功运行，但数据不会反映在数据库中。不确定缺少什么？ @DanielRoseman

from pymongo import MongoClient 
from pymongo.database import Database 
from pymongo.collection import Collection 

def upload(host, port, db_str, collection_str, src_dir): 
     # prepare connection to DB 
     client = MongoClient(host, port) 
     db = Database(client, db_str) 
     collection = Collection(db, collection_str) 

     # prepare bulk object 
     bulk = collection.initialize_ordered_bulk_op() 

     # iterate overall all data files and insert 
     for datafile in datafiles(src_dir): 
      try: 
       data = json.load(open(datafile)) 
       bulk.insert(data) 
      except ValueError: 
       print "Upload failed for %s" % (datafile) 
       continue 
     bulk.execute() 

Answer 1

返回的BulkWriteResult结果显示数据已正确上载到Mongo Db中。数据是否上传到正确的数据库和集合？
