颤动如何连接插座?

Question

Flutter 如何连接到套接字，我写一个 Python 脚本作为服务器，这个服务器端是这样的：

import socket
import time

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(("192.168.0.113", 9999))# 注意bind的这里，IP地址和端口号都要与前面的程序中一样
sock.listen(2)# 监听端口
# 等待数据源端连接
src, src_addr = sock.accept()
print "Source Connected by", src_addr
# 等待目标端连接
dst, dst_addr = sock.accept()
print "Destination Connected by", dst_addr
while True:
msg = src.recv(1024 *1024)
if not msg:
break
try:
dst.sendall(msg)
except Exception as ex:
dst, dst_addr = sock.accept()
print "Destination Connected Again by", dst_addr
except KeyboardInterrupt:
print "Interrupted"
break
src.close()
dst.close()

我想使用 Flutter 编写一个非常简单的客户端来显示通过套接字从这个 python 服务器发送的图像，如何实现这一点？

Answer 1

我不知道原始套接字，但如果你可以在Python中使用WebSockets，你可以使用web_socket_channel包：

import 'package:web_socket_channel/io.dart';
import 'package:web_socket_channel/status.dart' as status;
main() async {
var channel = await IOWebSocketChannel.connect("ws://localhost:1234");
channel.stream.listen((message) {
channel.sink.add("received!");
channel.close(status.goingAway);
}, onDone: () => print("Stream closed"));
}
