### Description I have a json string stored in a variable, and I want to iterate over the values in it. This works if there are integer values in the json string. But if it consists only of string values, jansson_get throws an error. According to jsonlint, all my json strings are valid. ### Troubleshooting #### Reproduction This is the part of kamailio.cfg leading to the error: ``` # Integer json array $var(myIntList) = '[2,3,4,5]'; xlog("L_INFO", "Integer json string is >>>> $var(myIntList) <<<<"); jansson_get('[0]', $var(myIntList), "$var(intValue)"); xlog("L_INFO", "First Int Element: >> $var(intValue) <<"); jansson_get('[1]', $var(myIntList), "$var(intValue)"); xlog("L_INFO", "Second Int Element: >> $var(intValue) <<"); # String json array $var(myStringList) = '["foo", "bar", "baz"]'; xlog("L_INFO", "String json string is >>>> $var(myStringList) <<<<"); jansson_get('[0]', $var(myStrList), "$var(strValue)"); xlog("L_INFO", "First Str Element: >> $var(strValue) <<"); jansson_get('[1]', $var(myStrList), "$var(strValue)"); xlog("L_INFO", "Second Str Element: >> $var(strValue) <<"); # Mixed json array $var(myMixedList) = '[2, "bar"]'; xlog("L_INFO", "Mixed json string (int first) is >>>> $var(myMixedList) <<<<"); jansson_get('[0]', $var(myMixedList), "$var(mixedValue)"); xlog("L_INFO", "First Mixed Element: >> $var(mixedValue) <<"); jansson_get('[1]', $var(myMixedList), "$var(mixedValue)"); xlog("L_INFO", "Second Mixed Element: >> $var(mixedValue) <<"); $var(myMixedList) = '["bar", 2]'; xlog("L_INFO", "Mixed json string (string first) is >>>> $var(myMixedList) <<<<"); jansson_get('[0]', $var(myMixedList), "$var(mixedValue)"); xlog("L_INFO", "First Mixed Element: >> $var(mixedValue) <<"); jansson_get('[1]', $var(myMixedList), "$var(mixedValue)"); xlog("L_INFO", "Second Mixed Element: >> $var(mixedValue) <<"); ``` #### Log Messages This is the output generated by the above kamailio.cfg snippet. ``` Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: Integer json string is >>>> [2,3,4,5] <<<< Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: First Int Element: >> 2 << Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: Second Int Element: >> 3 << Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: String json string is >>>> ["foo", "bar", "baz"] <<<< Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: ERROR: jansson [jansson_funcs.c:59]: janssonmod_get(): failed to parse: 0 Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: ERROR: jansson [jansson_funcs.c:61]: janssonmod_get(): json error at line 1: '[' or '{' expected near '0' Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: First Str Element: >> 0 << Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: ERROR: jansson [jansson_funcs.c:59]: janssonmod_get(): failed to parse: 0 Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: ERROR: jansson [jansson_funcs.c:61]: janssonmod_get(): json error at line 1: '[' or '{' expected near '0' Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: Second Str Element: >> 0 << Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: Mixed json string (int first) is >>>> [2, "bar"] <<<< Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: First Mixed Element: >> 2 << Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: Second Mixed Element: >> bar << Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: Mixed json string (string first) is >>>> ["bar", 2] <<<< Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: First Mixed Element: >> bar << Jun 28 15:31:12 busch /usr/sbin/kamailio[29961]: INFO: <script>: Second Mixed Element: >> 2 << ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.0.2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 4.9.2 ``` * **Operating System**: Debian Jessie ``` Linux busch.domain 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1+deb8u1 (2017-02-22) x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
