.TH CURLOPT_MIME_OPTIONS 3 "2 Oct 2021" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_MIME_OPTIONS \- set MIME option flags
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MIME_OPTIONS, long options);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a long that holds a bitmask of CURLMIMEOPT_* defines. Each bit is a
|
|
Boolean flag used while encoding a MIME tree or multipart form data.
|
|
|
|
Available bits are:
|
|
.IP CURLMIMEOPT_FORMESCAPE
|
|
Tells libcurl to escape multipart form field and file names using the
|
|
backslash-escaping algorithm rather than percent-encoding (HTTP only).
|
|
|
|
Backslash-escaping consists in preceding backslashes and double quotes with
|
|
a backslash. Percent encoding maps all occurrences of double quote,
|
|
carriage return and line feed to %22, %0D and %0A respectively.
|
|
|
|
Before version 7.81.0, percent-encoding was never applied.
|
|
|
|
HTTP browsers used to do backslash-escaping in the past but have over time
|
|
transitioned to use percent-encoding. This option allows one to address
|
|
server-side applications that have not yet have been converted.
|
|
|
|
As an example, consider field or file name \fIstrange\\name"kind\fP.
|
|
When the containing multipart form is sent, this is normally transmitted as
|
|
\fIstrange\\name%22kind\fP. When this option is set, it is sent as
|
|
\fIstrange\\\\name\\"kind\fP.
|
|
.SH DEFAULT
|

0, meaning disabled.
