参考技术A 安装react-native-tcp
按照官网配置就可以，不明白的可以跟着以下步骤
1、yarn add react-native-tcp
2、react-native link react-native-tcp
3、yarn add rn-nodeify
4、把下面这句

添加到package.json里面如图所在位置后，然后在终端执行一下 yarn postinstall 即可：

5、别忘记加上这句

接着就可以复制以下内容尝试了

TCP套接字

TCPSockServer：

from socket import *
from time import ctime
BUFFSISE = 1024
HOST = ‘127.0.0.1‘
PORT = 10054
mySocket = socket(AF_INET, SOCK_STREAM, 0)
ADDR = (HOST, PORT)
mySocket.bind(ADDR)
mySocket.listen(5)
while True:
    print("waiting for connection...\n")
    clietSocket, clientAddr = mySocket.accept()
    print("recive an request from: ", clientAddr)
    while True:
        data = clietSocket.recv(BUFFSISE).decode()
        print("received data: %s" % data)
        if not data:
            break
        clietSocket.send((‘[%s] %s‘ % (ctime(), data)).encode())
    clietSocket.close()
mySocket.close()

TCPSockClient：

from socket import *
HOST = ‘127.0.0.1‘
PORT = 10054
ADDR = (HOST, PORT)
BUFFSIZE = 1024
mySocket = socket(AF_INET, SOCK_STREAM, 0)
mySocket.connect(ADDR)
while True:
    data = input(">: ")
    if not data:
        break
    mySocket.send(data.encode())
    data = mySocket.recv(BUFFSIZE)
    if not data:
        break
    print(data)
mySocket.close()
