Currently changing user_agent by passing different strings to the html_session() method.

有没有办法在抓取网站时更改计时器上的 IP 地址?

Is there also a way to change your IP address on a timer when scraping a website?

推荐答案

您可以通过 use_proxy 使用代理(更改您的 ip)，如下所示:

You can use a proxy (which changes your ip) via use_proxy as follows:

html_session("you-url", use_proxy("proxy-ip", port))

更多详情参见:?httr::use_proxy

要检查它是否正常工作，您可以执行以下操作:

To check if it is working you can do the following:

require(httr)

content(GET("https://ifconfig.co/json"), "parsed")
content(GET("https://ifconfig.co/json", use_proxy("138.201.63.123", 31288)), "parsed")

第一次调用将返回您的 IP.第二次调用应该返回 138.201.63.123 作为 ip.

The first call will return your IP. The second call should return 138.201.63.123 as ip.

此代理取自 http://proxylist.hidemyass.com/ - 没有任何保证...
