download.file()“无法打开网址”

Question

我试图找出这个 URL 有什么问题，或者为什么我的 RStudio 无法访问我可以使用浏览器访问的完美 URL。
此 URL 会自动下载一个

.csv

该代码过去曾为同事工作过。

url <- "http://climate.weather.gc.ca/climate_data/bulk_data_e.html?format=csv&stationID=6329&Year=1953&Month=1&Day=1&timeframe=2&submit= Download+Data"

download.file(url,"files.csv",quiet=TRUE)

它抛出的错误是：

Error in download.file(url, "files.csv", quiet = TRUE) : 
  cannot open URL 'http://climate.weather.gc.ca/climate_data/bulk_data_e.html?format=csv&stationID=6329&Year=1953&Month=1&Day=1&timeframe=2&submit= Download+Data'

另外：警告信息：

In download.file(url, "files.csv", quiet = TRUE) :
  URL 'http://climate.weather.gc.ca/climate_data/bulk_data_e.html?format=csv&stationID=6329&Year=1953&Month=1&Day=1&timeframe=2&submit= Download+Data': status was 'URL using bad/illegal format or missing URL'

Answer 1

从 URL 中删除

submit=

部分。

> tmp <- tempfile()
> download.file(url, tmp, quiet=TRUE)
