如何在R中检查多个关于其状态代码的URL

Question

library(httr)
r <- GET("http://httpbin.org/get")
status_code(r)

data$URLS
#Where data$URLS is a column of URLS

data$status <- GET(data$URLS)
status_code(data$URLS)

Answer 1

我们可以使用for循环

for(i in seq_along(urls)) {
    tmp <- GET(urls[i])
    print(status_code(tmp))
}
#[1] 200
#[1] 200

数据

urls <-c("https://en.wikipedia.org/wiki/India","https://en.wikipedia.org/wiki/USA")
