From ac0babd412e3b5282136a5c5c5be2c4cc4be6895 Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Tue, 23 Jan 2024 18:56:23 +0100 Subject: api: provide api definition over api This patch allows a client to bootstrap itself by downloading the JSON API definitions over the API itself. This patch enables it for Python (probably need a dynamic language). Call VPPApiClient with the new bootstrapapi=True parameter. Example (Python): from vpp_papi import VPPApiClient vpp = VPPApiClient(bootstrapapi=True) rv = vpp.connect("foobar") assert rv == 0 print(f'SHOW VERSION: {vpp.api.show_version()}') vpp.disconnect() Type: feature Change-Id: Id903fdccc82b2e22aa1994331d2c150253f2ccae Signed-off-by: Ole Troan --- src/vlibmemory/memclnt_api.c | 36 +++++++++++++++++++++++++++++++++++- 1 file changed, 35 insertions(+), 1 deletion(-) (limited to 'src/vlibmemory/memclnt_api.c') diff --git a/src/vlibmemory/memclnt_api.c b/src/vlibmemory/memclnt_api.c index 7eb61fe7875..299e8d93f02 100644 --- a/src/vlibmemory/memclnt_api.c +++ b/src/vlibmemory/memclnt_api.c @@ -145,10 +145,44 @@ vl_api_control_ping_t_handler (vl_api_control_ping_t *mp) ({ rmp->vpe_pid = ntohl (getpid ()); })); } +static void +vl_api_get_api_json_t_handler (vl_api_get_api_json_t *mp) +{ + vl_api_get_api_json_reply_t *rmp; + api_main_t *am = vlibapi_get_main (); + int rv = 0, n = 0; + u8 *s = 0; + + vl_api_registration_t *rp = + vl_api_client_index_to_registration (mp->client_index); + if (rp == 0) + return; + + s = format (s, "[\n"); + u8 **ptr; + vec_foreach (ptr, am->json_api_repr) + { + s = format (s, "%s,", ptr[0]); + } + s[vec_len (s) - 1] = ']'; // Replace last comma with a bracket + vec_terminate_c_string (s); + n = vec_len (s); + +done: + REPLY_MACRO3 (VL_API_GET_API_JSON_REPLY, n, ({ + if (rv == 0) + { + vl_api_c_string_to_api_string ((char *) s, &rmp->json); + } + })); + vec_free (s); +} + #define foreach_vlib_api_msg \ _ (GET_FIRST_MSG_ID, get_first_msg_id) \ _ (API_VERSIONS, api_versions) \ - _ (CONTROL_PING, control_ping) + _ (CONTROL_PING, control_ping) \ + _ (GET_API_JSON, get_api_json) /* * vl_api_init -- cgit 1.2.3-korg
