I'm new to here. the ambient is R, I structured a simple web-scrape with rvest to pick up some images. When I save it into my folder it tells me that the file is not supported. Anybody know why?



library(rvest)

url <- "http://x.yupoo.com/photos/05941188/albums"

imgsrc <- read_html(url) %>%
html_node(xpath = '//*/img') %>%
html_attr('src')

download.file(
paste0(url, imgsrc), destfile = 'myimage.jpg', method="curl"
)

  • Welcome to SO. First, just making sure you know html_node() will return only one node vs html_nodes() which will return all found nodes. Next, did you look at the contents of imgsrc before you used it in the paste0()? It's value is "https://upzip.b0.upaiyun.com/website/4.4.22/imgs/logo_3.png" so you are — in effect — creating an invalid URL reference to a non-existent resource with the paste0()

  • thank you for the answer! so for you which would be the exact code to extract one of those images?
