无法使用 Pymongo 将数据从 PLC 插入 MongoDB

Question

我想使用 Pymongo 将 PLC 中的数据（字符串 - 'Hello World'）插入 MongoDB。我无法弄清楚为什么没有创建集合并且没有将'Hello World' 插入其中。你能解释一下我哪里出错了吗？这是我到目前为止编写的代码：

    #!/usr/bin/python
    import socket         
    import socket
    from pymongo import MongoClient
    import datetime

    # Connection to server (PLC) PLC's IP addr is .135
    server = socket.socket()         
    host = '10.52.124.135' 
    port = 4840  

    server.connect((host, port))
    print server.recv(1024)

    server.close 

    #Connection to Client (Mongodb) on port 27017
    IP = '10.52.124.186'
    PORT = 27017
    BUFFER_SIZE = 1024

    client = MongoClient('10.52.124.186', 27017)
    db = client.RXMMongoDB
    collection = db.ABC

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind((IP, PORT))
    s.listen(1)

    # connections loop
    while True:
            conn, addr = s.accept()
            print 'Connection address:',addr
            try:
                     # read loop
                     while True:
                          data = server.recv(BUFFER_SIZE)

                          if not data: 
                                  break

                          # send to Mongo
                          mongodoc = { "data": data, "date" : datetime.datetime.utcnow() }
                          db.ABC.insert_one(mongodoc)
            finally:
                     conn.close()

这样的事情对你有帮助吗？

import datetime
from pymongo import MongoClient

client = MongoClient('1.2.3.4',27017)
db = client.dbTest
data = "Hello SO World"
mongodoc = { "data": data, "date" : datetime.datetime.utcnow() }
db.myCollection.insert(mongodoc)

获得 PLC 数据后，您可能还想检查“数据”变量的内容吗？
