Python Socket 连接

Question

你好我要Python Socket Connect Poloniex API .
我运行了代码。但我无法得到我想要的结果。
我做了代码:
==================================================== ==================

import requests
import socket

s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.connect(("poloniex.com",443))

message="GET /public?command=returnTicker HTTP/1.1\r\nHost: poloniex.com\r\nConnection: keep-alive\r\nAccept-Encoding: gzip, deflate\r\nAccept: */*\r\nUser-Agent: python-requests/2.18.1\r\n\r\n"

s.send(message)

print s.recv(5000)

==================================================== ==================
响应文本:

HTTP/1.1 400 Bad Request

Server: cloudflare-nginx

Content-Type: text/html

Connection: close CF-RAY: - 400 The plain HTTP request was sent to HTTPS port

==================================================== ==================

Answer 1

错误消息是正确的 - 您正在向 HTTPS 端口 443 端口发送 HTTP 请求。如果要发送 HTTP 请求，请使用端口 80。我刚刚尝试向端口 80 发送请求，响应说我应该从现在开始使用 HTTPS(参见 Location: https:// 部分):

HTTP/1.1 301 Moved Permanently
Date: Tue, 20 Jun 2017 13:40:52 GMT
Content-Type: text/html
Transfer-Encoding: chunked
Connection: keep-alive

在这种情况下，您应该使用 ssl模块而不是 socket , 或直接使用 requests因为它是一个更简单的选择。
