This module implements a JSON server that handles GET requests and generates JSON responses.
Specifies the root path for JSON requests: http://[opensips_IP]:[opensips_httpd_port]/[mi_json_root]
The default value is "json".
Example 1.1. Set mi_json_root
parameter
... modparam("mi_json", "mi_json_root", "opensips_mi_json") ...
Trace destination as defined in the tracing module. Currently the only tracing module is proto_hep. This is where traced mi messages will go.
WARNING: A tracing module must be loaded in order for this parameter to work. (for example proto_hep).
Default value is none(not defined).
Example 1.2. Set trace_destination
parameter
... modparam("proto_hep", "trace_destination", "[hep_dest]10.0.0.2;transport=tcp;version=3") modparam("mi_json", "trace_destination", "hep_dest") ...
Filter traced mi commands based on a blacklist or a whitelist. trace_destination must be defined for this parameter to have any purpose. Whitelists can be defined using 'w' or 'W', blacklists using 'b' or 'B'. The type is separate by the actual blacklist by ':'. The mi commands in the list must be separated by ','.
Defining a blacklists means all the commands that are not blacklisted will be traced. Defining a whitelist means all the commands that are not whitelisted will not be traced. WARNING: One can't define both a whitelist and a blacklist. Only one of them is allowed. Defining the parameter a second time will just overwrite the first one.
WARNING: A tracing module must be loaded in order for this parameter to work. (for example proto_hep).
Default value is none(not defined).
Example 1.3. Set trace_destination
parameter
... ## blacklist ps and which mi commands ## all the other commands shall be traced modparam("mi_json", "trace_bwlist", "b: ps, which") ... ## allow only sip_trace mi command ## all the other commands will not be traced modparam("mi_json", "trace_bwlist", "w: sip_trace") ...
Commands with large responses (like ul_dump) will fail if the configured size of the httpd buffer is to small (or if there isn't enough pkg memory configured).
Future realeases of the httpd and mi_json modules will address this issue.
This is an example showing the JSON format for the “get_statistics net: uri:” MI command. Notice how the parameters are comma-separated then URI-encoded.
Example 1.4. JSON request
GET /json/get_statistics?params=net%3A%2Curi%3A HTTP/1.1 Accept: application/json Host: example.net HTTP/1.1 200 OK Content-Length: 49 Content-Type: application/json Date: Fri, 01 Nov 2013 12:00:00 GMT ["net:waiting_udp = 0", "net:waiting_tcp = 0", "uri:positive checks = 0", "uri:negative_checks = 0"]
Here is another example showing the JSON format for the “ps” MI command.
Example 1.5. JSON request
GET /json/ps HTTP/1.1 Accept: application/json Host: example.net HTTP/1.1 200 OK Content-Length: 428 Content-Type: application/json Date: Fri, 01 Nov 2013 12:00:00 GMT [{"name":"Process", "value":null, "attributes":{"ID": "0", "PID": "7400", "Type": "stand-alone SIP receiver udp:127.0.0.1:5060"}}, {"name":"Process", "value":null, "attributes":{"ID": "1", "PID": "7402", "Type": "HTTPD INADDR_ANY:8888"}}, {"name":"Process", "value":null, "attributes":{"ID": "2", "PID": "7403", "Type": "time_keeper"}}, {"name":"Process", "value":null, "attributes":{"ID": "3", "PID": "7404", "Type": "timer"}}]

(1) DevScore = author_commits + author_lines_added / (project_lines_added / project_commits) + author_lines_deleted / (project_lines_deleted / project_commits)
(2) including any documentation-related commits, excluding merge commits. Regarding imported patches/code, we do our best to count the work on behalf of the proper owner, as per the "fix_authors" and "mod_renames" arrays in opensips/doc/build-contrib.sh. If you identify any patches/commits which do not get properly attributed to you, please submit a pull request which extends "fix_authors" and/or "mod_renames".
(3) ignoring whitespace edits, renamed files and auto-generated files
