Передача файла через lws_client_connect_info

Как я могу передать json используя lws_client_connect_info?

struct lws_client_connect_info ccinfo = {0};
    ccinfo.context  = context;
    ccinfo.address  = HOST;
    ccinfo.port     = PORT;
    ccinfo.host     = lws_canonical_hostname( context );
    ccinfo.path     = "";
    ccinfo.origin   = "origin";
    ccinfo.protocol = protocols[0].name;
    ccinfo.ssl_connection = LCCSCF_USE_SSL | LCCSCF_ALLOW_SELFSIGNED | LCCSCF_SKIP_SERVER_CERT_HOSTNAME_CHECK;

    struct lws* conn = lws_client_connect_via_info(&ccinfo);
