Support a res$send variant that doesn't convert data to character? about ambiorix HOT 6 CLOSED

Thanks! I see the same thing, raw content coming through untransformed.

Thanks!

I will have to add something to better handle this.
However, httpuv only allows returning a character vector of length 1.

By raw vector do you mean something like the output of charToRaw?
If so, I'm guessing paste0(x, collapse ="") would be enough (until I provide something better)

In the response body httpuv supports character vector or raw vector. See: rstudio/httpuv#216

In this case by raw vector I mean a protocol buffer. I don't think your work around would work for me as I don't control the receiver, and it's expecting binary.

OK. Can you reinstall the latest dev version and try again?
It should not convert your response body to character.

If that still does not work could you share a reproducible example?

OK, I truly fixed it now, this works.
Requires latest Github version.

library(ambiorix)

img <- "https://www.r-project.org/logo/Rlogo.png"

temp <- tempfile(fileext = ".png")
download.file(img, temp)

size <- file.info(temp)$size
con <- file(temp, "rb")
raw <- readBin(con, raw(), size)
unlink(temp, force = TRUE)
close(con)

print(class(raw))

# core app
app <- Ambiorix$new()

app$get("/", \(req, res){
  res$header("Content-Length", size)
  res$header("Content-Type", "image/png")
  res$send(raw)
})

app$start()
