在Linux環境下,使用Python進行數據傳輸可以通過多種方式實現。以下是一些常見的方法:

  1. 使用socket庫進行TCP/UDP通信:
import socket

# 創建TCP套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('localhost', 12345))
server_socket.listen(5)

while True:
    client_socket, addr = server_socket.accept()
    data = client_socket.recv(1024)
    print("Received data:", data.decode())
    client_socket.sendall(data)
    client_socket.close()

客戶端代碼:

import socket

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(('localhost', 12345))
client_socket.sendall(b'Hello, Server!')
data = client_socket.recv(1024)
print("Received data:", data.decode())
client_socket.close()
  1. 使用requests庫進行HTTP請求:

首先安裝requests庫:

pip install requests

發送GET請求:

import requests

url = 'https://api.example.com/data'
response = requests.get(url)
print("Received data:", response.text)

發送POST請求:

import requests

url = 'https://api.example.com/data'
data = {'key': 'value'}
response = requests.post(url, json=data)
print("Received data:", response.text)
  1. 使用kafka-python庫進行Kafka消息傳輸:

首先安裝kafka-python庫:

pip install kafka-python

生產者代碼:

from kafka import KafkaProducer

producer = KafkaProducer(bootstrap_servers='localhost:9092')
producer.send('my_topic', key=b'my_key', value=b'my_value')
producer.flush()

消費者代碼:

from kafka import KafkaConsumer

consumer = KafkaConsumer('my_topic', bootstrap_servers='localhost:9092', auto_offset_reset='earliest', group_id='my_group')
for msg in consumer:
    print("Received data:", msg.value.decode())
  1. 使用pyarrow庫進行Parquet文件傳輸:

首先安裝pyarrow庫:

pip install pyarrow

將數據保存為Parquet文件:

import pandas as pd
import pyarrow as pa
import pyarrow.parquet as pq

data = {'column1': [1, 2, 3], 'column2': ['A', 'B', 'C']}
df = pd.DataFrame(data)
table = pa.Table.from_pandas(df)
pq.write_table(table, 'data.parquet')

從Parquet文件讀取數據:

import pandas as pd
import pyarrow.parquet as pq

table = pq.read_table('data.parquet')
df = table.to_pandas()
print("Received data:", df)

這些方法可以幫助你在Linux環境下使用Python進行數據傳輸。你可以根據自己的需求選擇合適的方法。
