RSelenium与chromedriver 2.20在Ubuntu 14.04 webdriver异常上

Question

我已在我的linux服务器上安装了chromedriver并正在运行

1. Query documents in the database
2. Get a timestamp from the ID's of the documents in the database
3. Set a range of the timestamps
4. Compare returned timestamps vs a timestamp range variable (yesterdays date in this case)
5. Have the DB return only documents that are within the range

R抛出错误：

Starting ChromeDriver 2.20.353124 (035346203162d32c80f1dce587c8154a1efa0c3b) on port 9515
Only local connections are allowed.

Answer 1

解决方案是使用DISPLAY参数手动调用Selenium服务器。

command <- "DISPLAY=:1 xvfb-run java -jar /usr/local/lib/R/site-library/RSelenium/bin/selenium-server-standalone.jar &"
system(command, intern = FALSE)
