在学习使用request.get方法的时候，传递代理IP的参数，一直返回301错误，代码如下，有哪位老师帮忙看下？：
import requests

proxies = {
    "http": "http://124.90.140.17:16649",
    "https": "https://124.90.140.17:16649"
}
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36'}
response = requests.get('http://httpbin.org/get', headers=headers, proxies=proxies)

print(type(response))
print(response.status_code)
print(type(response.text))
print(response.text)

返回如下：OSError: Tunnel connection failed: 301 Moved Permanently
