[Bioc-devel] How to handle Empty reply from server from httr package

[Jianhong Ou, Ph.D.]

Hi all,

Sometime my package got "Empty reply from server" error when I using httr package.
The pseudo-code I used to handle error is like this:

library(httr)
APIurl <- "https://www.ebi.ac.uk/proteins/api/features?offset=0&size=-1&reviewed=true&types=DNA_BIND%2CMOTIF%2CDOMAIN&taxid=9606&accession=K7PPA8%2CP04637%2CQ53GA5%2CH2EHT1%2CA0A087X1Q1%2CA0A087WXZ1%2CA0A087WT22"
tryCatch({
response <- GET(featureURL)
if(!http_error(response)){    content <- httr::content(response)}
}, error=function(e){
  message(e)
},warning=function(w){
  message(w)
},interrupt=function(i){
  message(i)
})

But I did not get the error handled. What is the correct way to handle the curl 52 error?
Thank you for your help.


Yours Sincerely,

Jianhong Ou
