当verbose=TRUE时从curl包捕获消息

我需要捕获从各种curl函数输出的详细消息

这里有一个例子

testCurlCalls <- function(x){
  ## Setting up data vendor calls in parallel
  ###############################
  out <<- list()
  dbout <<- list()
  # This is function, function which will be run if data vendor call is successful
  complete = function(res){
      # cat("Request done! Status:", res$status, "\n")
      out <<- c(out, list(res))
  }

  error_out <<- list()

  error = function(res){
    # cat("Request done! Status:", res$status, "\n")
    error_out <<- c(error_out, list(res))
  }

  h1 <- new_handle(url = "https://httpbin.org/get", verbose = TRUE)
  handle_setopt(h1, customrequest = "GET")
  handle_setform(h1, a = "1", b = "2.1")

  multi_add(h1, done = complete, fail = error)

  result <- multi_run(timeout = 20)

  list(
    result = result
    ,status_codes = sapply(out, function(x){x$status_code})
  )

}

testcalls尝试了它。你不尝试另一个软件包吗？我使用curl同时运行多个调用，因此我们需要一些与curl兼容的东西。你不尝试另一个软件包吗？我使用curl同时运行多个调用，因此我们需要一些与curl一起工作的东西
