crul 1.4.2

DOCUMENTATION

INTERNAL

  • tweak to test helper base url setup (#178)

crul 1.4

ASYNC RETRIES

Via the two issues (#135) and (#159) crul now supports http retries in: Async, AsyncVaried, AsyncQueue, and the request builder class HttpRequest

crul 1.3

CRAN release: 2022-09-03

BUG FIXES

  • improved error message for Async when urls and disk vector lengths do not match (they must match) (#165) thanks @shakraz

crul 1.2

DOCUMENTATION

  • fix example in AsyncQueue docs (#146) thanks @johnbaums !
  • update HttpClient docs to state that it’s an R6 class, and give some details on what an R6 class is and links to more info (#155)

NEW FEATURES

  • AsyncQueue gains methods: parse, status_code, status, content, and times (#156)
  • $responses() method now returns an S3 class with an associated print method to prevent printing a lot of results to the screen; print method pritns a summary of results, and at most 10 results, just status code and url (#157)

MINOR IMPROVEMENTS

  • parsing response headers gains a check for whether encoding is valid, and if not tries to set Latin1 encoding, and if that doesn’t work, fails out with message (#163) (#164) thanks @FlukeAndFeather

crul 1.1

NEW FEATURES

  • Paginator gains support for query parameter combination page/per_page to automatically paginate (#145)

MINOR IMPROVEMENTS

  • fix typo (#149) thanks @dpprdan
  • Change to how numbers are handled in query parameters. We unfortunately hadn’t tested this package with large numbers, which were being converted to scientific notation with a certain number of digits before a decimal. Fixed handling of query parameters to avoid this problem. Fix for Paginator as well as for HttpClient (#151) (#152) (#153) thanks @ateucher

BUG FIXES

  • sometimes weird response headers are returned in an HTTP response that can not be easily parsed; crul would raise an error when this header parsing happens, but now we raise a warning instead (#150)

crul 1.0

  • ok() can now accept more than 1 status code so that you can check if the status of a url is within a set of status codes rather than equal to 1 status code (#124)
  • ok() gains a parameter verb to use either head or get requests. in addition added more documentation (#125) to the function on how to get the “right answer” for whether a url is ok/up (#123) (#127)
  • ok() gains parameter ua_random, which if TRUE, will use a random user agent string pulled from a vector of 50 user agent strings generated from charlatan::UserAgentProvider (#138)

NEW FEATURES

  • gains new async class AsyncQueue for doing async requests with rate limits (#139)
  • gains new functions curl_verbose() and set_verbose(). curl_verbose() can be set by passing to the initialize step (e.g., HttpClient$new(url, verbose=curl_verbose())), and gets more compact verbose curl output, while also getting request body information (and response body optionally). set_verbose() is sets curl_verbose() globally (#141)
  • gains new vignette “How to choose a client” for choosing which crul class to use (e.g., HttpClient vs. Async) (#133) (#143)

MINOR IMPROVEMENTS

  • package sticker done, shown in README (#42)
  • improve function/class reference page in docs site (#131)
  • improvements to the best practices vignette (#132)
  • removed unused private variable in the AsyncVaried class (#140)
  • fix inaccuracy in documentation for the RETRY method (#130)
  • HttpRequest now adds the query (if present) to the printed url in the print method for the class (it was absent before now) (#128)
  • use new roxygen2 support for R6 classes (#126)
  • removed delete-requests and post-requests manual files - mostly redundant with other documentation

crul 0.9.0

CRAN release: 2019-11-06

NEW FEATURES

  • HttpResponse response object gains new methods for checking response content types, includes: raise_for_ct, raise_for_ct_html, raise_for_ct_json, raise_for_ct_xml. these behave similarly to raise_for_status, and can behave as a warning or raise an error through stop (#119) (#120)

MINOR IMPROVEMENTS

  • fix to prep_body internal function to handle various body inputs; now avoids warning about as.character.form_file when both httr and crul are loaded (#112)
  • finish off “Failing with fauxpas” section of the “API package best practices” vignette (#121)

BUG FIXES

  • the head() verb on HttpClient was no capturing auth when set on initialization (#122)

crul 0.8.4

CRAN release: 2019-08-02

MINOR IMPROVEMENTS

  • jsonlite package moved to Imports (#112)
  • the parse() method in the HttpResponse object now checks whether the response raw bytes can be converted to character, and if not just returns raw bytes (#115) (#116)
  • give vignettes titles (#113) (#114)

BUG FIXES

  • no longer setting cainfo curl option, fixes problem arising from change in recent libcurl version (#117)

crul 0.8.0

CRAN release: 2019-06-28

NEW FEATURES

  • you can now pass on parameters through the parse() method of an HttpResponse class to the internally called function iconv() to finely control the usage of iconv for cases in which normal encoding conversion doesn’t work (#110)

MINOR IMPROVEMENTS

  • use httpcode package instead of fauxpas package within ok() function (#108) (#109) thanks @maelle !
  • fix links to http testing book - ropensci -> ropenscilabs (#111)

crul 0.7.4

CRAN release: 2019-03-28

NEW FEATURES

  • event hooks added to HttpClient. both request and response hooks supported. not supported in async methods for now (#76) (#107)

MINOR IMPROVEMENTS

  • improve $parse() behavior (in the HttpResponse object) when using disk or stream. $parse() was throwing a warning when using disk and an error when using stream. and improves behavior when doing async requests (#104)
  • Paginator gains optional progress bar through the new progress parameter. In addition, the cat() calls inside the method were removed, so as not to insert newlines with each page and to not print “OK” when done (#106) thanks @boshek

BUG FIXES

  • passing on opts/headers now works with Async (#101) (#103)
  • streaming was broken in AsyncVaried with curl of a certain version, works now (#102) (#103)

crul 0.7.0

CRAN release: 2019-01-04

NEW FEATURES

  • HttpClient gains a retry method: retries any request verb until successful (HTTP response status < 400) or a condition for giving up is met. (#89) (#95) thanks @hlapp
  • HttpClient, HttpRequest, and Async classes gain verb method for doing HTTP requests specifying any of the supported HTTP verbs (#97)
  • HttpClient and Paginator gain a url_fetch method: get the URL that would be sent in an HTTP request without sending the HTTP request. Useful for getting the URL before executing an HTTP request if you need to check something about the URL first. (#92)
  • new vignette for “API package best practices” (#65)
  • Package gains manual files for each HTTP verb to facilitate linking to package documentation for information on each HTTP verb (#98)
  • Intermediate headers (e.g., those in redirect chains) are now given back in a new slot in the HttpResponse class as $response_headers_all as an unnamed list, with each element a named list of headers; the last list in the set is the final response headers that match those given in the $response_headers slot (#60) (#99)

BUG FIXES

  • some dangling file connections were left open - now fixed (#93) (#95)
  • fix url_parse: lacked check that input was a string, and that it was length 1 - this PR fixed that (#100) thanks @aaronwolen

DEFUNCT

  • HttpStubbedResponse was removed from the package - it may have been used at some point, but is not used in the package anymore (#88)

crul 0.6.0

CRAN release: 2018-07-10

NEW FEATURES

  • Async and AsyncVaried now support simple auth, see ?auth (#70)
  • gains new function ok() to ping a URL to see if it’s up or not, returns a single boolean (#71) (#73)
  • HttpClient and HttpRequest gain new parameter progress that accepts a function to use to construct a progress bar. For now accepts httr::progress() but will accept other options in the future (#20) (#81)
  • gains a new vignette for curl options (#7)
  • can now set curl options globally using new functions set_auth(), set_headers(), set_opts(), set_proxy(), and crul_settings() (#48) (#85)

MINOR IMPROVEMENTS

  • explicitly import httpcode::http_code (#80)
  • fix vignette names to make them more clear and add numbers to order them (#64)
  • change print function for Async and AsyncVaried to print max of 10 and tell user how many total and remaining not shown (#72)
  • added support to proxy() for socks, e.g. to use with TOR (#79)
  • now when Async and AsyncVaried requests fail, they don’t error but instead we capture the error and pass it back in the result. this way any failure requests don’t stop progress of the entire async request suite (#74) (#84)

crul 0.5.2

CRAN release: 2018-02-24

MINOR IMPROVEMENTS

  • Fixed handling of user agent: you can pass a UA string as a curl option or a header. Previously, we were wrongly overwriting the user input UA if given as a curl option - but were not doing so if given as a header. This is fixed now. (#63) thx to @maelle and @dpprdan

BUG FIXES

  • Fix to Paginator - it wasn’t handling pagination correctly. In addition, fixed to hopefully handle all scenarios now. added more tests (#62)
  • Fixed handling of query parameters. We were using urltools::url_encode to encode strings, but it wasn’t encoding correctly in some locales. Using curl::curl_escape fixes the problem. Encoding is done on query values and names (#67) (#68)

crul 0.5.0

CRAN release: 2018-01-22

NEW FEATURES

  • Gains a new R6 class Paginator to help users automatically paginate through multiple requests. It only supports query parameter based paginating for now. We’ll add support later for other types including cursors (e.g., used in Solr servers), and for link headers (e.g., used in the GitHub API). Please get in touch if you find any problems with Paginator. (#56)
  • Async classes Async and Asyncvaried gain ability to write to disk and stream data (to disk or elsewhere, e.g. R console or to an R object) (#46) thanks @artemklevtsov for the push to do this

MINOR IMPROVEMENTS

  • Improved documentation for auth to indicate that user and pwd are indeed required - and to further indicate that one can pass in NULL to those parameters (similar to an empty string "" in httr::authenticate) when one e.g. may want to use gssnegotiate method (#43)
  • Fixed query builder so that one can now protect query parameters by wrapping them in I() (#55)

BUG FIXES

  • Fixed bug in head requests with HttpClient when passing query parameter - it was failing previously. Added query parameter back. (#52)

crul 0.4.0

CRAN release: 2017-10-02

NEW FEATURES

  • file uploads now work, see new function upload() and examples (#25)

MINOR IMPROVEMENTS

  • fixes to reused curl handles - within a connection object only, not across connection objects (#45)
  • crul now drops any options passed in to opts or to ... that are not in set of allowed curl options, see curl::curl_options() (#49)
  • cookies should now be persisted across requests within a connection object, see new doc ?cookies for how to set cookies (#44)
  • gather cainfo and use in curl options when applicable (#51)
  • remove disk and stream from head method in HttpClient and HttpRequest as no body returned in a HEAD request

crul 0.3.8

CRAN release: 2017-06-14

BUG FIXES

  • Fixed AsyncVaried to return async responses in the order that they were passed in. This also fixes this exact same behavior in Async because Async uses AsyncVaried internally. (#41) thanks @dirkschumacher for reporting

crul 0.3.6

CRAN release: 2017-05-23

  • Note: This version gains support for integration with webmockr, which is now on CRAN.

NEW FEATURES

  • New function auth() to do simple authentication (#33)
  • New function HttpStubbedResponse for making a stubbed response object for the webmockr integration (#4)
  • New function mock() to turn on mocking - it’s off by default. If webmockr is not installed but user attempts to use mocking we error with message to install webmockr (#4)

MINOR IMPROVEMENTS

  • Use gzip-deflate by deafult for each request to make sure gzip compression is used if the server can do it (#34)
  • Change useragent to User-Agent as default user agent header (#35)
  • Now we make sure that user supplied headers override the default headers if they are of the same name (#36)

crul 0.3.4

CRAN release: 2017-03-31

NEW FEATURES

  • New utility functions url_build and url_parse (#31)

MINOR IMPROVEMENTS

  • Now using markdown for documentation (#32)

crul 0.3.0

CRAN release: 2017-02-17

NEW FEATURES

  • Added support for asynchronous HTTP requests, including two new R6 classes: Async and AsyncVaried. The former being a simpler interface treating all URLs with same options/HTTP method, and the latter allowing any type of request through the new R6 class HttpRequest (#8) (#24)
  • New R6 class HttpRequest to support AsyncVaried - this method only defines a request, but does not execute it. (#8)

MINOR IMPROVEMENTS

  • Added support for proxies (#22)

BUG FIXES

  • Fixed parsing of headers from FTP servers (#21)

crul 0.2.0

CRAN release: 2017-01-03

MINOR IMPROVEMENTS

  • request headers now passed correctly to response object (#13)
  • response headers now parsed to a list for easier access (#14)
  • Now supporting multiple query parameters of the same name, wasn’t possible in last version (#15)

crul 0.1.6

CRAN release: 2016-12-17

NEW FEATURES

  • Improved options for using curl options. Can manually add to list of curl options or pass in via .... And we check that user doesn’t pass in prohibited options (curl package takes care of checking that options are valid) (#5)
  • Incorporated fauxpas package for dealing with HTTP conditions. It’s a Suggest, so only used if installed (#6)
  • Added support for streaming via curl::curl_fetch_stream. stream param defaults to NULL (thus ignored), or pass in a function to use streaming. Only one of memory, streaming or disk allowed. (#9)
  • Added support for streaming via curl::curl_fetch_disk. disk param defaults to NULL (thus ignored), or pass in a path to write to disk instead of use memory. Only one of memory, streaming or disk allowed. (#12)

MINOR IMPROVEMENTS

  • Added missing raise_for_status() method on the HttpResponse class (#10)

BUG FIXES

  • Was importing httpcode but wasn’t using it in the package. Now using the package in HttpResponse
