This module is an implementation of an JSON-RPC v2.0 client http://www.jsonrpc.org/specification. that can send a call to a JSON-RPC server over a TCP connection.
NOTE that the current version of this module does not support TCP connection reusage, nor asynchronous commands.
The amount of milliseconds OpenSIPS waits to connect to the the JSON-RPC server, until it times out.
Default value is “500 milliseconds”.
The amount of milliseconds OpenSIPS waits to send a RPC command to the JSON-RPC server, until it times out.
Default value is “500 milliseconds”.
The amount of milliseconds OpenSIPS waits for the JSON-RPC server to respond to a JSON-RPC request, until it times out. Note that these parameter only affects the jsonrpc_request command.
Default value is “500 milliseconds”.
Does a JSON-RPC request to the JSON-RPC server indicated in the destination parameter, and waits for a reply from it.
This function can be used from any route.
The function has the following parameters:
destination (string) - address of the JSON-RPC server. The format needs to be IP:port.
method (string) - the method used in the RPC request.
params (string) - these are the parameters sent to the RPC method. This parameter needs to be a properly formated JSON array, or JSON object, according the the JSON-RPC specifications.
ret_var a writeable variable used to store the result of the JSON-RPC command. If the command returns an error, the variable will be populated with the error JSON, otherwise, with the body of the JSON-RPC result.
The function has the following return codes:
1 - JSON-RPC command executed successfully, and the server returned success. You can check the ret_pvar variable for the result.
-1 - There was an internal error during processing.
-2 - There was a connection (timeout or connect) error with the destination.
-3 - The JSON-RPC was successfully run, but the server returned an error. Check the ret_pvar value to find out more information.
Example 1.4. jsonrpc_request() function usage
...
if (!jsonrpc_request("127.0.0.1", "add", "[1,2]", $var(ret))) {
xlog("JSON-RPC command failed with $var(ret)\n");
exit;
}
xlog(JSON-RPC command returned $var(ret)\n");
# parse $var(ret) as JSON, or whatever the function returns
...
Does a JSON-RPC notification to the JSON-RPC server indicated in the destination parameter, but unlike jsonrpc_request(), it does not wait for a reply from the JSON-RPC server.
This function can be used from any route.
The function receives the same parameters as jsonrpc_request(), except for the ret_pvar. Also, the same values are returned.
Example 1.5. jsonrpc_notification() function usage
...
if (!jsonrpc_notification("127.0.0.1", "block_ip", "{ \"ip": \"$si\" }")) {
xlog("JSON-RPC notification failed with $rc!\n");
exit;
}

(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".
