fedstat_post_data_ids_filtered: Post data filters ids to fedstat.ru and download specified...

In fedstatAPIr: Unofficial API for Fedstat (Rosstat EMISS System) for Automatic and Efficient Data Queries

Post data filters ids to fedstat.ru and download specified subset of data

Description

Creates a request body from data_ids and sends it to https://www.fedstat.ru/indicator/downloadData.do?format={format}. Gets an sdmx or excel with data in binary format.

The request includes a CSRF token that is automatically extracted by fedstat_get_data_ids and passed through via data.frame attributes. CSRF tokens are single-use: each POST consumes the token. For subsequent downloads, call fedstat_get_data_ids again.

If no CSRF token is found in data_ids attributes (e.g. when using cached data_ids from a previous session), the function will attempt to fetch a fresh token automatically with a warning.

sdmx raw bytes can be passed to fedstat_parse_sdmx_to_table to create a data.frame or to rawToChar and writeLines to create an xml file

excel raw bytes can be passed to writeBin to create an xls file

Usage

fedstat_post_data_ids_filtered(
  data_ids,
  ...,
  data_format = c("sdmx", "excel"),
  timeout_seconds = 180,
  retry_max_times = 3,
  httr_verbose = NULL
)

Arguments

data_ids	data.frame, can be a result of fedstat_get_data_ids or fedstat_get_data_ids_special_cases_handle to download all available data, or a result of fedstat_data_ids_filter to download subset of available data
...	other arguments passed to httr::POST
data_format	string, one of sdmx, excel
timeout_seconds	numeric, maximum time before POST request times out
retry_max_times	numeric, not used for POST (CSRF tokens are single-use), but used for fallback GET if CSRF token needs to be fetched
httr_verbose	httr::verbose() or NULL, outputs messages to the console about the processing of the request

Value

raw bytes (sdmx or excel)
