Hi dudes! Consider the following file:
http://brook.no-ip.org/download/content.bin request: # debugdump.txt just for debuging $ url --header "Content-Type:application/octet-stream" --trace-ascii debugdump.txt --data-binary @content.bin http://localhost:9090 and example: #include <microhttpd.h> #include <stdio.h> #include <string.h> static int answer_to_connection(void *cls, struct MHD_Connection *connection, const char *url, const char *method, const char *version, const char *upload_data, size_t *upload_data_size, void **con_cls) { if (!*con_cls) { *con_cls = (void *) 1; return MHD_YES; } *con_cls = NULL; printf("*upload_data_size: %zd\n", *upload_data_size); return MHD_NO; } int main(void) { struct MHD_Daemon *daemon; daemon = MHD_start_daemon(MHD_USE_SELECT_INTERNALLY, 9090, NULL, NULL, &answer_to_connection, NULL, MHD_OPTION_END); getchar(); MHD_stop_daemon(daemon); return 0; } the result is: *upload_data_size: 1995 but the upload_data buffer contains only 746 characters. OK, my file is a binary that contains some NULLs, so it should be sent via multipart/form-data, however, I've tested it with other servers and the binary content is sent properly as application/octet-stream. (eg. NodeJS uses its req.buffer to get octet-streams) It seems MHD's payload (upload_data) ends with first NULL character. So, is there any chance to get a binary content without using HTML forms? Thank you! -- Silvio Clécio
