在REST API中使用参数R

当curl命令中有-d/--data时，它实际上是一个带有表单数据的POST调用(即它不能与httr::GET()一起工作)

httr的继承者httr2附带了curl_translate()工具，它试图为你翻译curl个命令，结果通常是有点原始，但应该会给你正确的方向:

httr2::curl_translate('curl https://api.todoist.com/sync/v9/completed/get_all \ -H "Authorization: Bearer 000api_key000" \ -d limit=200')
#> request("https://api.todoist.com/sync/v9/completed/get_all") %>% 
#>   req_headers(
#>     Authorization = "Bearer 000api_key000",
#>   ) %>% 
#>   req_body_raw("limit=200", "application/x-www-form-urlencoded") %>% 
#>   req_perform()

要判断将发送到服务器的内容，我们可以将req_perform()临时替换为req_dry_run():

library(httr2)
request("https://api.todoist.com/sync/v9/completed/get_all") |>
  req_headers(
    Authorization = "Bearer 000api_key000",
  ) |>
  req_body_raw("limit=200", "application/x-www-form-urlencoded") |>
  req_dry_run()
#> POST /sync/v9/completed/get_all HTTP/1.1
#> Host: api.todoist.com
#> User-Agent: httr2/0.2.3 r-curl/5.1.0 libcurl/8.3.0
#> Accept: */*
#> Accept-Encoding: deflate, gzip
#> Authorization: <REDACTED>
#> Content-Type: application/x-www-form-urlencoded
#> Content-Length: 9
#> 
#> limit=200

由于有适当的方法用于承载令牌和表单正文，因此可以将相同的请求写为:

request("https://api.todoist.com/sync/v9/completed/get_all") |>
  req_auth_bearer_token("000api_key000") |>
  req_body_form(limit = 200) |>
  req_dry_run()
#> POST /sync/v9/completed/get_all HTTP/1.1
#> Host: api.todoist.com
#> User-Agent: httr2/0.2.3 r-curl/5.1.0 libcurl/8.3.0
#> Accept: */*
#> Accept-Encoding: deflate, gzip
#> Authorization: <REDACTED>
#> Content-Type: application/x-www-form-urlencoded
#> Content-Length: 9
#> 
#> limit=200

如果你需要帮助翻译成httr，也有https://curlconverter.com/r/，这将返回:

require(httr)

headers = c(
  `Authorization` = "Bearer 000api_key000",
  `Content-Type` = "application/x-www-form-urlencoded"
)

data = list(
  `limit` = "200"
)

res <- httr::POST(url = "https://api.todoist.com/sync/v9/completed/get_all", httr::add_headers(.headers=headers), body = data, encode = "form")
