Passing post data in command line is convenient but has limited size, and may become tricky to correctly escape passed data especially in scripts. This patch add the option --post-file so the data to post can be read from a file or from /dev/stdin. Tested on x86/64.
Signed-off-by: Gioacchino Mazzurco <g...@eigenlab.org> Signed-off-by: Daniel Golle <dan...@makrotopia.org> --- v3: use 1024 bytes buffer instead of 1000, use sizeof() As original wget also only supports "application/x-www-form-urlencoded" as Content-Type for the POST data, keep it that way in uclient-fetch as well for now. An additional option --post-type may be introduced at a later stage to allow setting "text/json" or "application/octet-stream". v2: make it compile, handle errors, add usage info, fix typos uclient-fetch.c | 31 +++++++++++++++++++++++++++++-- 1 file changed, 29 insertions(+), 2 deletions(-) diff --git a/uclient-fetch.c b/uclient-fetch.c index a06be5d..061f0fd 100644 --- a/uclient-fetch.c +++ b/uclient-fetch.c @@ -43,6 +43,7 @@ static const char *user_agent = "uclient-fetch"; static const char *post_data; +static const char *post_file; static struct ustream_ssl_ctx *ssl_ctx; static const struct ustream_ssl_ops *ssl_ops; static int quiet = false; @@ -334,7 +335,7 @@ static int init_request(struct uclient *cl) msg_connecting(cl); - rc = uclient_http_set_request_type(cl, post_data ?
