[Experimental]

  • resp_stream_raw() retrieves bytes (raw vectors).

  • resp_stream_lines() retrieves lines of text (character vectors).

  • resp_stream_sse() retrieves server-sent events from the stream. It currently only works with text mode connections so when calling req_perform_connection() you must use mode = "text".

Usage

resp_stream_raw(resp, kb = 32)

resp_stream_lines(resp, lines = 1, max_size = Inf, warn = TRUE)

resp_stream_sse(resp, max_size = Inf)

# S3 method for class 'httr2_response'
close(con, ...)

Arguments

resp, con

A streaming response created by req_perform_connection().

kb

How many kilobytes (1024 bytes) of data to read.

lines

The maximum number of lines to return at once.

max_size

The maximum number of bytes to buffer; once this number of bytes has been exceeded without a line/event boundary, an error is thrown.

warn

Like readLines(): warn if the connection ends without a final EOL.

...

Not used; included for compatibility with generic.

Value

  • resp_stream_raw(): a raw vector.

  • resp_stream_lines(): a character vector.

  • resp_stream_sse(): a list with components type, data, and id; or NULL, signifying that the end of the stream has been reached or–if in nonblocking mode–that no event is currently available.
