Pass any httr request to time

A GET request

GET("https://google.com") %>% time(count = 3)
#> 32.656 kb - https://www.google.com/ code:200 time(ms):172.394
#> 32.472 kb - https://www.google.com/ code:200 time(ms):122.082
#> 31.504 kb - https://www.google.com/ code:200 time(ms):77.588
#> <http time>
#>   Avg. min (ms):  77.588
#>   Avg. max (ms):  172.394
#>   Avg. mean (ms): 124.0213

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):274.325
#> 11.368 kb - https://hb.cran.dev/post code:200 time(ms):113.367
#> 11.36 kb - https://hb.cran.dev/post code:200 time(ms):117.252
#> <http time>
#>   Avg. min (ms):  113.367
#>   Avg. max (ms):  274.325
#>   Avg. mean (ms): 168.3147

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)
#> 31.536 kb - http://www.google.com/ code:200 time(ms):148.827
#> 31.552 kb - http://www.google.com/ code:200 time(ms):144.872
#> 30.896 kb - http://www.google.com/ code:200 time(ms):106.855
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):           106.855 148.827 133.518
#>   Tedirect (s):        35.438 51.067 43.328
#>   Namelookup time (s): 0 3.29 1.096667
#>   Connect (s):         0 22.459 7.486333
#>   Pretransfer (s):     0.446 22.653 7.901
#>   Starttransfer (s):   105.495 119.818 112.3813

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):  85.906
#>   Avg. max (ms):  186.178
#>   Avg. mean (ms): 143.4717

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
