I need to download information from web site that is protected using cookies. I pass this protection manually and then insert cookies to httr.

Here is similar topic, but it does not solve my problem: (Copying cookie for httr)

library(httr)
url<-"http://smida.gov.ua/db/emitent/year/xml/showform/32153/125/templ"

cook<-"_SMIDA=9117a9eb136353bd6956651bd59acd37; __utmt=1; __utma=29983421.1729484844.1413489369.1413625619.1413627797.3; __utmb=29983421.7.10.1413627797; __utmc=29983421; __utmz=29983421.1413489369.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)"

response <- GET(url, config(cookie= cook))

content(x = response,as = 'text', encoding = "UTF-8")

So when I use content it return me information, that I am not logged in( as I do without cookie)

How can I solve this problem?

Test credentials are login: mytest2, pass: qwerty12)

这将是set_cookies使用GET&的方法httr：

GET("http://smida.gov.ua/db/emitent/year/xml/showform/32153/125/templ", 
    set_cookies(`_SMIDA` = "7cf9ea4bfadb60bbd0950e2f8f4c279d",
                `__utma` = "29983421.138599299.1413649536.1413649536.1413649536.1",
                `__utmb` = "29983421.5.10.1413649536",
                `__utmc` = "29983421",
                `__utmt` = "1",
                `__utmz` = "29983421.1413649536.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)"))

这对我有用，至少我认为它确实有效，因为我无法阅读该语言。返回的表具有相同的结构，并且没有提示登录。

不幸的是，登录时的验证码会阻止使用 Rselenium（或其他类似的爬行包），因此您必须继续手动获取这些 cookie（或使用实用程序从会话中提取它们）。

最后，您现在可能要认真考虑更改这些凭据 :-)

编辑： @VadymB和我都发现代码在我们重新启动 RStudio之前不起作用。你的旅费可能会改变。
