Question

我正在尝试让服务器等待客户端建立连接，从客户端获取数据，使用该数据发出api请求，然后将响应发送给客户端。除了将响应发送回客户端（客户端功能刚刚超时）之外，其他所有操作都正常。如果将conn.sendall（“ anythinghere”）放入while True循环内，则此方法有效，但显然不会返回我需要它返回的内容。将conn.sendall放置在循环之外会导致客户端超时。

服务器代码

conn, addr = s.accept()

print('Connected by', addr)
fragments = []
while True:
    chunk = conn.recv(4096)
    if not chunk:
        break
    fragments.append(chunk)

action = "".join(fragments)

URL = "http://172.31.55.211/" + action

print("making request")
r = requests.get(url = URL)
data = r.json()

conn.sendall(data['message'])

客户代码

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    print(s)
    s.connect((HOST, PORT))
    s.sendall(b'hellocvs')
    data = s.recv(1024)

    print('Received', repr(data))

    return {
        'statusCode': 200,
        'body': json.dumps(str(data))
    }
