r - Copying cookie for httr -


i'm trying access site sets cookie on basis of type of visitor: 

library(httr) url <- "https://www.blackrock.com/ca/individual/en/products/product-list#categoryid=1&lvl2=overview"

essentially i've tried returns this...:

get(url)

response [https://www.blackrock.com/ca/individual/en/site-entry?targeturl=%2fca%2findividual%2fen%2fproducts%2fproduct-list%3fsiteentrypassthrough%3dtrue]   status: 200   content-type: text/html;charset=utf-8   size: 270 kb <!doctype html><html xmlns="http://www.w3.org/1999/xhtml" prefix="og: http://ogp.me/ns#" lang="en" xml:lang="en"><head><meta content="text/html;charset=utf-8" http-equiv="content-type... <meta name="description" content="" /> <meta name="robots" content="noindex,noarchive,nocache" /> <meta property="og:title" content="site entry" /> <meta property="og:type" content="website" /> <meta property="og:image" content="/amer-retail-assets/include/common/images/blackrock_logo.png" /> <meta property="og:site_name" content="blackrock" /> <meta property="og:locale" content="en_ca" /> <meta property="og:url" content="https://www.blackrock.com/ca/individual/en/site-entry?locale=en_ca" /> <link rel="canonical" href="https://www.blackrock.com/ca/individual/en/site-entry?locale=en_ca" />

so, instead tried copying cookie after manually passing gateway or site-entry page in chrome: 

cookie = c(`jsession_amer-retail01` = "ac91c17f269d8f6a136e576531fa6e05", `unicaid` = "10.39.18.249-1408392737241856", `unicaniodid` = "nqhknkqykdm-yxueygx", `_ga` = "ga1.2.127078965.1408392737", `blkusertype-ca-one` = "institutional", `s_pers` = "%20s_fid%3d14569e53c0f4ee51-3982590542b2dda4%7c1471566685393%3b%20gpv%3dca-one%257cproducts%257cproduct%2520list%7c1408410085400%3b%20s_nr%3d1408408285405-repeat%7c1439944285405%3b%20s_pers_evar15%3dprospect%7c1411000285408%3b%20s_pers_prop19%3danonymous%7c1411000285411%3b", `s_sess` = "%20s_cc%3dtrue%3b%20s_sq%3d%3b",  `s_vi` = "[cs]v1|29f92f108507b6c6-6000010a8000e2ed[ce]", `ts-ca-one-locale` = "en_ca")

get(url, set_cookies(.cookies = cookie), user_agent("mozilla/5.0"))

this returns same result.

however, when @ examples httr think results i'm getting setting cookie incorrect.

for example:

> example(set_cookies)

st_cks> set_cookies(a = 1, b = 2) config:  list of 1  $ cookie:"a1=;b2="  st_cks> set_cookies(.cookies = c(a = "1", b = "2")) config:  list of 1  $ cookie:"a1=;b2="  st_cks> get("http://httpbin.org/cookies") response [http://httpbin.org/cookies]   status: 200   content-type: application/json   size: 19 b {   "cookies": {}  st_cks> get("http://httpbin.org/cookies", set_cookies(a = 1, b = 2)) response [http://httpbin.org/cookies]   status: 200   content-type: application/json   size: 50 b {   "cookies": {     "a1": "",      "b2": ""   }

i have expected httpbin.org return = 1 , b = 1 instead of a1 = , b2 =. doing wrong?

you're not doing wrong (at least imo). taking @ set_cookies, there's bit of code there:

cookie <- paste0(names(cookies), cookies_str, sep = "=", collapse = ";")

which not working intended (i.e. it's turning a = "1" a1= instead of a=1).

you can use one:

sc2 <- function (..., .cookies = character(0)) {    cookies <- c(..., .cookies)   stopifnot(is.character(cookies))   cookies_str <- vapply(cookies, rcurl::curlescape, fun.value = character(1))   cookie <- paste(names(cookies), cookies_str, sep = "=",                     collapse = ";")   config(cookie = cookie)  }  get("http://httpbin.org/cookies", sc2(a = 1, b = 2))  ## response [http://httpbin.org/cookies] ##   status: 200 ##   content-type: application/json ##   size: 50 b ## { ##   "cookies": { ##     "a": "1",  ##     "b": "2" ##   }

that uses paste instead of paste0 temporarily until that's fixed (i'll file issue on httr github repo).

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
