    Python 示例代码 1

    #!/usr/bin/python
    import pymongo
    import random
    
    mongodbUri = 'mongodb://mongouser:thepasswordA1@10.66.187.127:27017/admin'
    
    client = pymongo.MongoClient(mongodbUri)
    db = client.somedb
    db.user.drop()
    element_num=10
    for id in range(element_num):
        name = random.choice(['R9','cat','owen','lee','J'])
        sex = random.choice(['male','female'])
        db.user.insert_one({'id':id, 'name':name, 'sex':sex})
    
    content = db.user.find()
    for i in content:
        print i
    

    Python 示例代码 2

    #!/usr/bin/python
    import pymongo
    mongodbUri = 'mongodb://mongouser:thepasswordA1@10.66.187.127:27017/admin'
    client = pymongo.MongoClient(mongodbUri)
    db = client.someonedb
    
    inserted_id = db.somecoll.insert_one({"somekey":"yiqihapi"}).inserted_id
    print inserted_id
    
    for doc in db.somecoll.find(dict(_id=inserted_id)):
            print doc
    
    for doc in db.somecoll.find({"somekey":"yiqihapi"}):
            print doc

    输出:

    5734431e101e2f6d699b37ef
    {u'somekey': u'yiqihapi', u'_id': ObjectId('5734431e101e2f6d699b37ef')}
    {u'somekey': u'yiqihapi', u'_id': ObjectId('5734431e101e2f6d699b37ef')}
