Module: sip-router Branch: master Commit: c98100c76d257308bf6ad600a6e48604ed85efe1 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=c98100c… Author: Miklos Tirpak &lt;miklos(a)iptel.org&gt; Committer: Miklos Tirpak &lt;miklos(a)iptel.org&gt; Date: Wed May 13 16:59:39 2009 +0200 @ruri.rn_user is introduced. - The select call returns the value of "rn" parameter if exists, otherwise the user name of the URI. Visual separators are removed from the user name if needed, and they are always removed from the "rn" parameter value. - Nested function call, it works with any URI. --- select_core.c | 89 +++++++++++++++++++++++++++++++++++++++++++++++--------- select_core.h | 2 + 2 files changed, 76 insertions(+), 15 deletions(-) diff --git a/select_core.c b/select_core.c index ffe874d..79b49ca 100644 --- a/select_core.c +++ b/select_core.c @@ -717,6 +717,74 @@ int select_uri_user(str* res, select_t* s, struct sip_msg* msg) RETURN0_res(uri.user); } +/* search for a parameter with "name" + * Return value: + * 0: not found + * 1: found + * -1: error + * + * val is set to the value of the parameter. + */ +static inline int search_param(str *params, char *name, int name_len, + str *val) +{ + param_hooks_t h; + param_t *p, *list; + + if (params->s == NULL) + return 0; + + if (parse_params(params, CLASS_ANY, &h, &list) < 0) + return -1; + for (p = list; p; p=p->next) { + if ((p->name.len == name_len) + && (strncasecmp(p->name.s, name, name_len) == 0) + ) { + *val=p->body; + free_params(list); + return 1; + } + } + free_params(list); + return 0; +} + +/* Return the value of the "rn" parameter if exists, otherwise the user name. + * The user name is normalized if needed, i.e. visual separators are removed, + * the "rn" param is always normalized. */ +int select_uri_rn_user(str* res, select_t* s, struct sip_msg* msg) +{ + int ret; + str val; + + if (parse_uri(res->s, res->len, &uri)<0) + return -1; + + /* search for the "rn" parameter */ + if ((ret = search_param(&uri.params, "rn", 2, &val)) != 0) + goto done; + + if (uri.sip_params.s != uri.params.s) { + /* check also the original sip: URI parameters */ + if ((ret = search_param(&uri.sip_params, "rn", 2, &val)) != 0) + goto done; + } + + if ((uri.flags & URI_USER_NORMALIZE) == 0) + RETURN0_res(uri.user); + /* else normalize the user name */ + val = uri.user; +done: + if (ret < 0) + return -1; /* error */ + + if (!(res->s=get_static_buffer(val.len))) + return -1; + if ((res->len=normalize_tel_user(res->s, &val))==0) + return 1; + return 0; +} + int select_uri_pwd(str* res, select_t* s, struct sip_msg* msg) { if (parse_uri(res->s, res->len, &uri)<0) @@ -832,8 +900,6 @@ int select_uri_params(str* res, select_t* s, struct sip_msg* msg) int select_any_params(str* res, select_t* s, struct sip_msg* msg) { - param_hooks_t h; - param_t *p, *list=NULL; str* wanted; int i; @@ -851,20 +917,13 @@ int select_any_params(str* res, select_t* s, struct sip_msg* msg) wanted=&s->params[s->param_offset[select_level]+1].v.s; if (!res->len) return -1; - if (parse_params(res, CLASS_ANY, &h, &list)<0) return -1; - - for (p = list; p; p=p->next) { - if ((p->name.len==wanted->len) && - !strncasecmp(p->name.s, wanted->s,wanted->len)) { - *res=p->body; - free_params(list); - return (res->len ? 0 : 1); - } - } - free_params(list); - DBG("SELECT ...uri.params.%s NOT FOUND !\n", wanted->s); - return -1; + if (search_param(res, wanted->s, wanted->len, res) <= 0) { + DBG("SELECT ...uri.params.%s NOT FOUND !\n", wanted->s); + return -1; + } else { + return (res->len) ? 0 : 1; + } } int select_event(str* res, select_t* s, struct sip_msg* msg) diff --git a/select_core.h b/select_core.h index 6b2baff..f348be7 100644 --- a/select_core.h +++ b/select_core.h @@ -153,6 +153,7 @@ SELECT_F(select_any_params) SELECT_F(select_any_uri) SELECT_F(select_uri_type) SELECT_F(select_uri_user) +SELECT_F(select_uri_rn_user) SELECT_F(select_uri_pwd) SELECT_F(select_uri_host) SELECT_F(select_uri_port) @@ -278,6 +279,7 @@ static select_row_t select_core[] = { { select_rr_uri, SEL_PARAM_INT, STR_NULL, select_any_uri, NESTED}, { select_any_uri, SEL_PARAM_STR, STR_STATIC_INIT("type"), select_uri_type, 0}, { select_any_uri, SEL_PARAM_STR, STR_STATIC_INIT("user"), select_uri_user, 0}, + { select_any_uri, SEL_PARAM_STR, STR_STATIC_INIT("rn_user"), select_uri_rn_user, 0}, { select_any_uri, SEL_PARAM_STR, STR_STATIC_INIT("pwd"), select_uri_pwd, 0}, { select_any_uri, SEL_PARAM_STR, STR_STATIC_INIT("host"), select_uri_host, 0}, { select_any_uri, SEL_PARAM_STR, STR_STATIC_INIT("port"), select_uri_port, 0},
