rcurl

问题 ETA: Per https://github.com/hiratake55/RForcecom/issues/42, it looks like the author of the rforcecom package has updated rforcecom to use httr instead of RCurl (as of today, to be uploaded to CRAN tomorrow, 7/1/16), so my particular issue will be solved at that point. However, the general case (implementing TLS 1.1 / 1.2 in RCurl) may still be worth pursuing for other packages. Or everyone may just switch to the more recent curl package instead of RCurl. Background: I've been using the

问题 I am attempting to download some files onto my local from an ftp-server. I have had success using the following method to move .txt and .csv files from the server but not the .sas7bdat files that I need. protocol <- "sftp" server <- "ServerName" userpwd <- "User:Pass" tsfrFilename <- "/filepath/file.sas7bdat" ouptFilename <- "out.sas7bdat" # Run # ## Download Data url <- paste0(protocol, "://", server, tsfrFilename) data <- getURL(url = url, userpwd=userpwd) ## Create File fconn <- file

问题 When I try to call install_github, I get the following error (not just for this package, but for all github packages): > install_github('ramnathv/slidify') Downloading github repo ramnathv/slidify@master Error in curl::curl_fetch_memory(url, handle = handle) : Problem with the SSL CA cert (path? access rights?) But if I use RCurl directly to access github with ssl, I don't get any problem: > x <- getBinaryURL( url='https://github.com/ramnathv/slidify/archive/master.zip', followlocation=1L )

问题 I'm trying to get devtools::install_github() working behind my corporate proxy on Windows 7. So far I've had to do the following: > library(httr) > library(devtools) > set_config(use_proxy("123.123.123.123",8080)) > devtools::install_github("rstudio/ggvis") Installing github repo ggvis/master from rstudio Downloading master.zip from https://github.com/rstudio/ggvis/archive/master.zip Error in function (type, msg, asError = TRUE) : SSL certificate problem, verify that the CA cert is OK.

问题 I am having a bit of trouble installing XML and RCurl on my Ubuntu machine 13.10. I performed all sudo update and upgrades today. I am trying to use rattle for R. I am unable to install 'XML' which is required for the use of rattle. This is pretty much the same question that was asked right here just a year later and a different OS. Here are the error messages that I am getting back: > install.packages("RCurl") Installing package into ‘/home/steven/R/x86_64-pc-linux-gnu-library/3.0’ (as ‘lib’

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year . How can I download the content of a webpage and find all files with specific extension listed on it. And then download all of them. For example, I would like to download all netcdf files (with extension *.nc4) from the following webpage: https://data.giss.nasa.gov/impacts/agmipcf

问题 I wish to be able to have htmlParse work well with Hebrew, but it keeps to scramble the Hebrew text in pages I feed into it. For example: # why can't I parse the Hebrew correctly? library(RCurl) library(XML) u = "http://humus101.com/?p=2737" a = getURL(u) a # Here - the hebrew is fine. a2 <- htmlParse(a) a2 # Here it is a mess... None of these seem to fix it: htmlParse(a, encoding = "utf-8") htmlParse(a, encoding = "iso8859-8") This is my locale: > Sys.getlocale() [1] "LC_COLLATE=Hebrew

问题 I am trying to install RCurl on OS X 10.12.6 but get the following error: Error: package or namespace load failed for ‘RCurl’ in dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object '/Users/nick/Library/R/3.4/library/RCurl/libs/RCurl.so': dlopen(/Users/nick/Library/R/3.4/library/RCurl/libs/RCurl.so, 6): Library not loaded: @rpath/libcurl.4.dylib Referenced from: /Users/nick/Library/R/3.4/library/RCurl/libs/RCurl.so Reason: image not found Error: loading failed Execution halted

问题 I am trying and failing to use RCurl to automate the process of fetching a spreadsheet from a web site, China Labour Bulletin's Strike Map. Here is the URL for the spreadsheet with the options set as I'd like them: http://strikemap.clb.org.hk/strikes/api.v4/export?FromYear=2011&FromMonth=1&ToYear=2015&ToMonth=6&_lang=en Here is the code I'm using: library(RCurl) temp <- tempfile() temp <- getForm("http://strikemap.clb.org.hk/strikes/api.v4/export", FromYear="2011", FromMonth="1", ToYear="2015

问题 This is a followup question to RCurl getURL with loop - link to a PDF kills looping : I have the following getURL command: require(RCurl) #set a bunch of options for curl options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"))) agent="Firefox/23.0" curl = getCurlHandle() curlSetOpt( cookiejar = 'cookies.txt' , useragent = agent, followlocation = TRUE , autoreferer = TRUE , httpauth = 1L, # "basic" http authorization version -- this seems to make a
