write_stream

From httr v1.4.2 by Hadley Wickham

Process output in a streaming manner.

This is the most general way of processing the response from the server - you receive the raw bytes as they come in, and you can do whatever you want with them.

Usage

write_stream(f)

Arguments

f: Callback function. It should have a single argument, a raw vector containing the bytes recieved from the server. This will usually be 16k or less. The return value of the function is ignored.

Examples

# NOT RUN {
GET(
  "https://github.com/jeroen/data/raw/gh-pages/diamonds.json",
  write_stream(function(x) {
    print(length(x))
    length(x)
  })
)
# }
