无法执行rsDriver（连接被拒绝）

本文介绍了无法执行rsDriver（连接被拒绝）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我不能用R硒去任何地方。这是第一步，也是我的输出：I can't get anywhere with R selenium. Here's the first step and my output:library(RSelenium)rD <- rsDriver()# checking Selenium Server versions:# BEGIN: PREDOWNLOAD# BEGIN: DOWNLOAD# BEGIN: POSTDOWNLOAD# checking chromedriver versions:# BEGIN: PREDOWNLOAD# BEGIN: DOWNLOAD# BEGIN: POSTDOWNLOAD# checking geckodriver versions:# BEGIN: PREDOWNLOAD# BEGIN: DOWNLOAD# BEGIN: POSTDOWNLOAD# checking phantomjs versions:# BEGIN: PREDOWNLOAD# BEGIN: DOWNLOAD# BEGIN: POSTDOWNLOAD# [1] "Connecting to remote server"# Error in checkError(res) :# Undefined error in httr call. httr output: Failed to connect to localhost port 4567: Connection refused# In addition: Warning message:# In rsDriver() : Could not determine server status.我错过了什么？推荐答案 注意：此答案适用于Windows在尝试运行已弃用的 checkForServer（）时 Selenium提供了两种选择：When trying to run the deprecated checkForServer() Selenium offers two options: 使用rsDriver 使用Docker请参阅：RSelenium::checkForServer()# Error: checkForServer is now defunct. Users in future can find the function in# file.path(find.package("RSelenium"), "examples/serverUtils"). The# recommended way to run a selenium server is via Docker. Alternatively# see the RSelenium::rsDriver function. 每个人 似乎 要与rsDriver有关，而Docker是推荐的选项，因此我们将采用以下路线：Everybody seems to have issues with rsDriver and Docker is the recommended option so we'll go this route: 安装docker 运行它，根据要求重新启动计算机 通过在命令行中运行来拉映像： docker pull selenium / standalone-firefox （或 chrome 而不是 firefox ）或在R shell（'docker pull selenium / standalone-firefox'） 通过在命令行中运行来启动服务器： docker run -d -p 4445：4444 selenium / standalone-firefox 或在R shell中（'docker run -d -p 4445：4444 selenium / standalone-firefox'） 然后运行 remDr<-remoteDriver（remoteServerAddr =本地主机，端口= 4445L，浏览器名称= firefox）。该文档对虚拟机提出了一些不同的建议，但我无法使其正常工作。install dockerrun it, restart computer as requestedpull image by running in command line: docker pull selenium/standalone-firefox(or chrome instead of firefox) or in R shell('docker pull selenium/standalone-firefox')start server by running in command line: docker run -d -p 4445:4444 selenium/standalone-firefox or in R shell('docker run -d -p 4445:4444 selenium/standalone-firefox')Then run remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox'") . The doc suggests something different with a virtual machine but i couldn't get it to work.为此，我设置了以下代码：With this I was set, here is my code:shell('docker run -d -p 4445:4444 selenium/standalone-firefox')remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")remDr$open()remDr$navigate("http://www.google.com/ncr")remDr$getTitle()# [[1]]# [1] "Google"更多信息的文档： https://cran.r-project.org/web /packages/RSelenium/vignettes/RSelenium-basics.html https://cran.r-project.org/web/packages/RSelenium/vignettes/RSelenium-docker.htmlhttps://cran.r-project.org/web/packages/RSelenium/vignettes/RSelenium-basics.htmlhttps://cran.r-project.org/web/packages/RSelenium/vignettes/RSelenium-docker.html 这篇关于无法执行rsDriver（连接被拒绝）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
