--data-urlencode

Post data, similar to the other --data options with the exception that this performs URL-encoding.

To be CGI-compliant, the \<data> part should begin with a name followed by a separator and a content specification. The \<data> part can be passed to curl using one of the following syntaxes:

content

URL-encode the content and pass that on. Just be careful so that the content does not contain any = or @ symbols, as that makes the syntax match one of the other cases below.

=content

URL-encode the content and pass that on. The preceding = symbol is not included in the data.

name=content

URL-encode the content part and pass that on. Note that the name part is expected to be URL-encoded already.

@filename

load data from the given file (including any newlines), URL-encode that data and pass it on in the POST. Using @- makes curl read the data from stdin.

name@filename

load data from the given file (including any newlines), URL-encode that data and pass it on in the POST. The name part gets an equal sign appended, resulting in name=urlencoded-file-content. Note that the name is expected to be URL-encoded already.
