req_auth_aws_v4()
signs request using AWS's special format (#562, #566).req_cache()
no longer retrieves anything but GET
requests from the cache.resp_stream_aws()
to retrieve AWS's special streaming format. With thanks to https://github.com/lifion/lifion-aws-event-stream/ for a simple reference implementation.req_perform_parallel()
and req_perform_promise()
now correctly set up the method and body (#549).req_body_file()
now works with files >64kb once more (#524) and no longer leaks a connection if the response doesn't complete succesfully (#534).req_body_*()
now give informative error if you attempt to change the body type (#451).req_cache()
now re-caches the response if the body is hasn't been modified but the headers have changed (#442). It also works better when req_perform()
sets a path (#442).req_cookie_set()
allows you to set client side cookies (#369).req_perform()
no longer displays a progress bar when sleeping during tests. You can override this behaviour by setting the option httr2_progress
.req_perform_iterative()
is no longer experimental.req_perform_connection()
for working with streaming data. Unlike req_perform_stream()
which uses callbacks, req_perform_connection()
returns a regular response object with a connection as the body. Unlike req_perform_stream()
it supports req_retry()
(with @jcheng5, #519).req_retry()
no longer treates low-level HTTP failures the same way as transient errors by default. You can return to the previous behaviour with retry_on_error = TRUE
.resp_body_html()
and resp_body_xml()
now work when req_perform()
is given a path (#448).resp_stream_bytes()
, resp_stream_lines()
, and resp_stream_sse()
for streaming chunk from a connection response (#519).jwt_encode_hmac()
now calls correct underlying function
jose::jwt_encode_hmac()
and has correct default size parameter value
(@denskh, #508).
req_cache()
now prunes cache before checking if a given key exists,
eliminating the occassional error about reading from an invalid RDS file.
It also no longer tests for existence then later reads the cache, avoiding
potential race conditions.
New req_perform_promise()
creates a promises::promise
so a request can
run in the background (#501, @gergness).
req_perform_parallel()
now respects error handling in req_error()
.
req_body_file()
now only opens a connection when the request actually needs data. In particular, this makes it work better with req_perform_parallel()
(#487).req_cache()
no longer fails if the rds
files are somehow corrupted and now defaults the debug
argument to the httr2_cache_debug
option to make it easier to debug caching buried in other people's code (#486).req_oauth_password()
now only asks for your password once (#498).req_perform_parallel()
now works correctly with req_cache()
(#447) and now works when downloading 0 byte files (#478)req_perform_stream()
no longer applies the callback
to unsuccessful
responses, instead creating a regular response. It also now sets last_request()
and last_response()
(#479).req_url_query()
now allows you to opt out of escaping for multi-value parameters (#404).req_perform_stream()
gains a round = c("byte", "line")
argument to control
how the stream is rounded (#437).
req_retry()
gives a clearer error if after
returns the wrong type of
value (#385).
req_template()
now works when you have a bare :
in a template that
uses "uri" style (#389).
req_timeout()
now resets the value of connecttimeout
set by curl.
This ensures that you can use req_timeout()
to increase the connection
timeout past 10s (#395).
url_parse()
is considerably faster thanks to performance optimisations
by and discussion with @DyfanJones (#429).
local_mock()
and with_mock()
have been deprecated in favour of
local_mocked_responses()
and with_mocked_responses()
(#301).
multi_req_perform()
is deprecated in favour of req_perform_parallel()
.
req_stream()
is deprecated in favour of req_perform_stream()
(#314).
oauth_flow_auth_code()
deprecates host_name
and port
arguments in favour
of using redirect_uri
. It also deprecates host_ip
since it seems unlikely
that changing this is ever useful.
oauth_flow_auth_code_listen()
now takes a single redirect_uri
argument
instead of separate host_ip
and port
arguments. This is a breaking change
but I don't expect anyone to call this function directly (which was confirmed
by a GitHub search) so I made the change without deprecation.
req_body_form()
and req_body_multipart()
now require data ...
;
they no longer accept a single list for compatibility with the 0.1.0
API.
New req_perform_sequential()
performs a known set of requests
sequentially. It has an interface similar to req_perform_parallel()
but
with no limitations, and the cost of being slower (#361).
New req_perform_iterative()
performs multiple requests, where each request
is derived from the previous response (@mgirlich, #8).
req_perform_parallel()
replaces multi_req_perform()
to match the new
naming scheme (#314). It gains a progress
argument.
req_perform_iterative()
, req_perform_parallel()
, and
req_perform_sequential()
share a new error handling strategy. By
default, errors will be bubbled up, but you can choose an alternative
strategy with the on_error
argument (#372).
A new family of functions resps_successes()
, resps_failures()
,
resps_requests()
and resps_data()
make it easier to work with lists of
responses (#357). Behind the scenes, these work because the request is now
stored in the response (or error) object (#357).
resp_body_json()
and resp_body_xml()
now cache the parsed values so
that you can use them repeatedly without worrying about the performance cost.
This supports the design req_perform_iterative()
by avoiding the need to
carefully pass around a parsed object.
A new vignette("oauth")
gives many more details about how OAuth works and
how to use it with httr2 (#234), and the OAuth docs have been overhauled to
make it more clear that you should use req_oauth_*()
, not oauth_*()
(#330).
If you are using an OAuth token with a refresh token, and that refresh token has expired, then httr2 will now re-run the entire flow to get you a new token (#349).
New oauth_cache_path()
returns the path that httr2 uses for caching OAuth
tokens. Additionally, you can now change the cache location by setting the
HTTR2_OAUTH_CACHE
env var. This is now more obvious to the user, because
httr2 now informs the user whenever a token is cached.
oauth_flow_auth_code()
gains a redirect_uri
argument rather than deriving
this URL automatically from the host_name
and port
(#248). It uses
this argument to automatically choose which strategy to use to get the
auth code, either launching a temporary web server or, new, allowing you to
manually enter the details with the help of a custom JS/HTML page hosted
elsewhere, or by copying and pasting the URL you're redirected to
(@fh-mthomson, #326). The temporary web server now also respects the path
component of redirect_uri
, if the API needs a specific path (#149).
New oauth_token_cached()
allows you to get an OAuth token while still
taking advantage of httr2's caching and auto-renewal features. For expert
use only (#328).
@mgirlich is now a httr2 contributor in recognition of his many contributions.
req_cache()
gains max_n
, max_size
, and max_age
arguments to
automatically prune the cache. By default, the cache will stay under 1 GB
(#207).
New req_body_json_modify()
allows you to iteratively modify a JSON
body of a request.
New req_cookie_preserve()
lets you use a file to share cookies across
requests (#223).
New req_progress()
adds a progress bar to long downloads or uploads (#20).
New resp_check_content_type()
to check response content types (#190).
resp_body_json()
and friends give better errors if no Content-Type
header is present in the response (#284).
New resp_has_body()
returns a TRUE
or FALSE
depending on whether
or not the response has a body (#205).
New resp_url()
, resp_url_path()
, resp_url_queries()
and
resp_url_query()
to extract various part of the response url (#57).
req_url_query()
gains a .multi
parameter that controls what happens when
you supply multiple values in a vector. The default will continue to error
but you can use .multi = "comma"
to separate with commas, "pipe"
to
separate with |
, and "explode"
to generate one parameter for each
value (e.g. ?a=1&a=2
) (#350).
New secret_encrypt_file()
and secret_decrypt_file()
for encrypting and
decrypting files (#237).
The httr2 examples now only run on R 4.2 and later so that we can use the base pipe and lambda syntax (#345).
OAuth errors containing a url now correctly display that URL (instead of the string "uri").
curl_translate()
now uses the base pipe, and produces escapes with single
quotes or raw strings in case double quotes can't be used (@mgirlich, #264).
It gains the argument simplify_headers
that removes some common but
unimportant headers, like Sec-Fetch-Dest
or sec-ch-ua-mobile
(@mgirlich, #256). It also parses the query components of the url
(@mgirlich, #259) and works with multiline commands from the clipboard
(@mgirlich, #254).
local_mocked_responses()
and with_mocked_responses()
now accept a
list of responses which will be returned in sequence. They also now correctly
trigger errors when the mocked response represents an HTTP failure (#252).
oauth_flow_refresh()
now only warns, not errors, if the refresh_token
changes, making it a little easier to use in manual workflows (#186).
obfuscated()
values now display their original call when printed.
req_body_json()
gains custom content type
argument
and respects custom content-type set in header (@mgirlich, #189).
req_cache()
now combine the headers of the new response with the headers
of the cached response. In particular, this fixes resp_body_json/xml/html()
on cached responses (@mgirlich, #277).
req_perform()
now throws error with class httr2_failure/httr2_error
if
the request fails, and that error now captures the curl error as the parent.
If the request succeeds, but the response is an HTTP error, that error
now also has super class httr2_error
. This means that all errors thrown by
httr2 now inherit from the httr2_error
class. See new docs in ?req_error()
for more details.
req_perform()
's progress bar can be suppressed by setting
options(httr2_progress = FALSE)
(#251). Progress bars displayed while
waiting for some time to pass now tell you why they're waiting (#206).
req_oauth_bearer_jwt()
now includes the claim in the cache key (#192).
req_oauth_device()
now takes a auth_url
parameter making it usable
(#331, @taerwin).
req_url_query()
gains a .multi
parameter that controls what happens when
you supply multiple values in a vector. The default will continue to error
but you can use .multi = "comma"
to separate with commas, "pipe"
to
separate with |
, and "explode"
to generate one parameter for each
value (e.g. ?a=1&a=2
) (#350).
New example_url()
to launch a local server, making tests and examples
more robust.
New throttle_status()
to make it a little easier to verify what's happening
with throttling.
req_oauth_refresh()
now respects the refresh_token
for caching
(@mgirlich, #178).
req_perform()
now always sleeps before a request, rather than after it.
It also gains an error_call
argument and communicates more clearly
where the error occurred (@mgirlich, #187).
req_url_path()
and req_url_path_append()
can now handle NULL
or empty
...
and the elements of ...
can also have length > 1 (@mgirlich, #177).
sys_sleep()
(used by req_retry()
and req_throttle()
) gains a progress
bar (#202).
curl_translate()
can now handle curl copied from Chrome developer tools
(@mgirlich, #161).
req_oauth_*()
can now refresh OAuth tokens. One, two, or even more times!
(@jennybc, #166)
req_oauth_device()
can now work in non-interactive environments,
as intendend (@flahn, #170)
req_oauth_refresh()
and oauth_flow_refresh()
now use the envvar
HTTR2_REFRESH_TOKEN
, not HTTR_REFRESH_TOKEN
(@jennybc, #169).
req_proxy()
now uses the appropriate authentication option (@jl5000).
req_url_query()
can now opt out of escaping with I()
(@boshek, #152).
Can now print responses where content type is the empty string (@mgirlich, #163).
"Wrapping APIs" is now an article, not a vignette.
req_template()
now appends the path instead of replacing it (@jchrom, #133)
req_body_form()
, req_body_multipart()
, and req_url_query()
now
support multiple arguments with the same name (#97, #107).
req_body_form()
, req_body_multipart()
, now match the interface of
req_url_query()
, taking name-value pairs in ...
. Supplying a single
list()
is now deprecated and will be removed in a future version.
req_body_json()
now overrides the existing JSON body, rather than
attempting to merge with the previous value (#95, #115).
Implement req_proxy()
(owenjonesuob, #77).
httr_path
class renamed to httr2_path
to correctly match package name
(#99).
oauth_flow_device()
gains PKCE support (@flahn, #92), and
the interactive flow is a little more user friendly.
req_error()
can now correct force successful HTTP statuses to fail (#98).
req_headers()
will now override Content-Type
set by req_body_*()
(#116).
req_throttle()
correctly sets throttle rate (@jchrom, #101).
req_url_query()
never uses scientific notation for queries (#93).
req_perform()
now respects httr::with_verbose()
(#85).
response()
now defaults body
to raw(0)
for consistency with real
responses (#100).
req_stream()
no longer throws an error for non 200 http status codes (@DMerch, #137)
Fix R CMD check failures on CRAN
Added a NEWS.md
file to track changes to the package.
