推荐答案

我尝试了不同的方法，问题不在代理连接中，而是以R获得连接的方式进行。通过使用url（your_url，rb）定义二进制连接，问题就解决了。

I tried different ways and the problem was not in the proxy connection, but in the way that R gets the connection. Through the definition of a binary connection with url(your_url, "rb") the problem was solve.

con <- url("http://www.imdb.com/title/tt1490017/", "rb") 
lego_movie <- read_html(con)
