防火墙后面的 RCurl 中的 getURL 问题 R
我位于医院防火墙后面，通常必须使用 setInternet2(T) R 才能正确访问网络。然而，运行我的代码（在家里完美运行）会导致
curlPerform(curl = curl, .opts = opts, .encoding = .encoding) :
Could not resolve host: www.cnn.com; Host not found
Is it at all possible to work around this?
问候，

I'm behind hospital firewalls and usually have to use setInternet2(T) for R to access the net properly. However running my code (that works perfectly at home) results in
curlPerform(curl = curl, .opts = opts, .encoding = .encoding) :
Could not resolve host: www.cnn.com; Host not found
Is it at all possible to work around this?

看起来 RCurl 没有使用与 R 相同的代理设置（因此设置 internet2 没有帮助），您需要使用
curlSetOpt命令手动设置它们： - getCurlHandle()
curlSetOpt(.opts = list(proxy = '<地址>:<端口>'),curl = curl)ans <- getURL( 'http://www.cnn.com',curl=curl)It looks like RCurl doesn't use the same proxy settings as R (and so setting internet2 doesn't help), you need to set them manually, with the
curlSetOptcommand:curl <- getCurlHandle()curlSetOpt(.opts = list(proxy = '<address>:<port>'), curl = curl)ans <- getURL('http://www.cnn.com', curl = curl)
