Pass any httr request to time

A GET request

GET("https://google.com") %>% time(count = 3)
#> 32.824 kb - https://www.google.com/ code:200 time(ms):159.863
#> 32.576 kb - https://www.google.com/ code:200 time(ms):175.996
#> 31.6 kb - https://www.google.com/ code:200 time(ms):74.762
#> <http time>
#>   Avg. min (ms):  74.762
#>   Avg. max (ms):  175.996
#>   Avg. mean (ms): 136.8737

A POST request

POST("https://hb.cran.dev/post", body = "A simple text string") %>%
  time(count = 3)
#> 11.368 kb - https://hb.cran.dev/post code:200 time(ms):301.873
#> 11.368 kb - https://hb.cran.dev/post code:200 time(ms):91.587
#> 11.368 kb - https://hb.cran.dev/post code:200 time(ms):94.93
#> <http time>
#>   Avg. min (ms):  91.587
#>   Avg. max (ms):  301.873
#>   Avg. mean (ms): 162.7967

The return object is a list with slots for all the httr response objects, the times for each request, and the average times. The number of requests, and the delay between requests are included as attributes.

res <- GET("http://google.com") %>% time(count = 3)
#> 31.552 kb - http://www.google.com/ code:200 time(ms):128.805
#> 31.552 kb - http://www.google.com/ code:200 time(ms):213.895
#> 30.912 kb - http://www.google.com/ code:200 time(ms):356.413
attributes(res)
#> $names
#> [1] "times"    "averages" "request" 
#> 
#> $count
#> [1] 3
#> 
#> $delay
#> [1] 0.5
#> 
#> $class
#> [1] "http_time"

Or print a summary of a response, gives more detail

res %>% summary()
#> <http time, averages (min max mean)>
#>   Total (s):           128.805 356.413 233.0377
#>   Tedirect (s):        39.403 300.023 126.666
#>   Namelookup time (s): 0 4.086 1.362
#>   Connect (s):         0 22.169 7.389667
#>   Pretransfer (s):     0.52 22.268 7.798667
#>   Starttransfer (s):   107.22 355.05 219.8817

Messages are printed using cat, so you can suppress those using verbose=FALSE, like

GET("https://google.com") %>% time(count = 3, verbose = FALSE)
#> <http time>
#>   Avg. min (ms):  85.052
#>   Avg. max (ms):  197.077
#>   Avg. mean (ms): 154.5787

Ping an endpoint

This function is a bit different, accepts a url as first parameter, but can accept any args passed on to httr verb functions, like GET, POST, etc.

"https://google.com" %>% ping()
#> <http ping> 200
#>   Message: OK
#>   Description: Request fulfilled, document follows

Or pass in additional arguments to modify request

"https://google.com" %>% ping(config = verbose())
#> <http ping> 200
#>   Message: OK
#>   Description: Request fulfilled, document follows
