mg_parse_multipart() | mg_parse_multipart | func | size_t mg_parse_multipart(const char *buf, size_t buf_len, char *var_name, size_t var_name_len, char *file_name, size_t file_name_len, const char **chunk, size_t *chunk_len); |
Parses the buffer buf
, buf_len
that contains multipart form data chunks.
Stores the chunk name in a var_name
, var_name_len
buffer.
If a chunk is an uploaded file, then file_name
, file_name_len
is
filled with an uploaded file name. chunk
, chunk_len
points to the chunk data.
Return: number of bytes to skip to the next chunk or 0 if there are no more chunks.
Usage example:
static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
switch(ev) {
case MG_EV_HTTP_REQUEST: {
struct http_message *hm = (struct http_message *) ev_data;
char var_name[100], file_name[100];
const char *chunk;
size_t chunk_len, n1, n2;
n1 = n2 = 0;
while ((n2 = mg_parse_multipart(hm->body.p + n1,
hm->body.len - n1,
var_name, sizeof(var_name),
file_name, sizeof(file_name),
&chunk, &chunk_len)) > 0) {
printf("var: %s, file_name: %s, size: %d, chunk: [%.*s]\n",
var_name, file_name, (int) chunk_len,
(int) chunk_len, chunk);
n1 += n2;
}
}
break;
