爬虫 ProxyError 急！！！

Question

爬虫新手，在使用requests.get（）中proxies参数后仍旧报错

这不是最困惑的，最困惑的是同样的代码**在服务器上可以成功使用代理，然而我的电脑就无法使用代理，一旦使用就报错**
**之前我也使用过迅云vpn，不知道和这个有无关系

#更换ip函数
def get_proxies(web):
    while True:
        try:
            r = requests.get(web).text
        except Exception as e:
            print("ip更换过快")
            time.sleep(random.random()*3+3)
            continue
        print(json.loads(r))
        ip = json.loads(r)["data"][0]["ip"]
        port = json.loads(r)["data"][0]["port"]
        proxy = ip + ':' + str(port)
        proxies = {'http':'http://'+proxy,'https':'https://'+proxy}
        print(proxies)
        try:
            test = requests.get("https://httpbin.org/get",proxies = proxies,timeout=10).text
            print(test)
        except Exception as e:
            print('ip不可用')
            time.sleep(random.random() * 3 + 5)
            continue
        test = json.loads(test)
        print('ip为：',test["origin"])
        break
    return proxies

函数本身没有问题
报错：

Answer 1

在你的电脑的 internet 选项，连接，代理服务器中设置下这个代理ip，端口，通过浏览器访问，看看是否可以访问。
应该是某种机制阻断了代理服务器和你计算机的连接。
