httr_options
List available options.
This function lists all available options for config().
It provides both the short R name which you use with httr, and the longer
Curl name, which is useful when searching the documentation. curl_doc
opens a link to the libcurl documentation for an option in your browser.
Usage
httr_options(matches)curl_docs(x)
Arguments
- matches
If not missing, this restricts the output so that either the httr or curl option matches this regular expression.
- x
An option name (either short or full).
Details
RCurl and httr use slightly different names to libcurl: the initial
CURLOPT_ is removed, all underscores are converted to periods and
the option is given in lower case. Thus "CURLOPT_SSLENGINE_DEFAULT"
becomes "sslengine.default".
Value
A data frame with three columns:
The short name used in httr
The full name used by libcurl
The type of R object that the option accepts
Examples
# NOT RUN {
httr_options()
httr_options("post")
# Use curl_docs to read the curl documentation for each option.
# You can use either the httr or curl option name.
curl_docs("userpwd")
curl_docs("CURLOPT_USERPWD")
# }
