處理草圖和python程序之間的通信？

Question

我有一個處理程序（處理現場音頻）和一個用python編寫的程序（打電話給gatttool通過藍牙低能量與外設通信）。有沒有一種簡單的方法將值從處理髮送到python？我應該創建一個串行連接並以這種方式傳遞字節嗎？

Answer 1

請記住，它們運行在同一臺計算機上，最好使用套接字在Python端創建一個服務器，並在處理端創建一個客戶端，然後將數據從客戶端發送到服務器辦法。 Python服務器將等待來自處理客戶端的連接，並在收到數據後使用它。

你可以找到例子，如所有網站上，但這裏是由等待處理和Python文檔給出的例子：

Processing client:

import processing.net.*; 
Client myClient; 

void setup() { 
    size(200, 200); 
    /* Connect to the local machine at port 5204 
    * (or whichever port you choose to run the 
    * server on). 
    * This example will not run if you haven't 
    * previously started a server on this port. 
    */ 
    myClient = new Client(this, "127.0.0.1", 5204); 
} 

void draw() { 
    myClient.write("Paging Python!"); // send whatever you need to send here 
} 

Python server:

# Echo server program 
import socket 

HOST = ''     # Symbolic name meaning all available interfaces 
PORT = 50007    # Arbitrary non-privileged port 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
s.bind((HOST, PORT)) 
s.listen(1) 
conn, addr = s.accept() 
print('Connected by', addr) 
while True: 
    data = conn.recv(1024) 
    if not data: break 
    print(data) # Paging Python! 
    # do whatever you need to do with the data 
conn.close() 
# optionally put a loop here so that you start 
# listening again after the connection closes
