[SR-Users] Send JSON document over http and process response

[Colin Morelli]

Hey Jonathan,

You can also use the Jansson module to create the JSON request. For
example, in one of my configs, I have a route that looks basically like:

$var(params) = $null;
jansson_set("string", "request.uri", "$ru", "$var(params)");
jansson_set("string", "request.method", "$rm", "$var(params)");
jansson_set("string", "request.domain", "$rd", "$var(params)");
/// other fields set here
http_set_timeout(5000);
http_set_method("POST");
http_append_header("Content-Type: application/json");
http_async_query("https://mydomain.com/api/v1/blah", "$var(params)",
"API_ROUTE_REPLY");

Then a API_ROUTE_REPLY block that processes the response like:

if $http_ok {
    if $http_rs == 200 {
      $var(action) = $null;
      jansson_get_field("$http_rb", "authentication.action",
"$var(action)");
      // other stuff
   }
}

Hopefully that's helpful.

Best,
Colin
