Modulo operator is supported via `filter_func` parameter 🙂 ### Example A route that matches only if the value of a query parameter `test_query_param` is even. Route configuration (admin API): ```bash curl http://127.0.0.1:9180/apisix/admin/routes/filterfunc_modulo -H "X-API-KEY: $admin_key" -X PUT -i -d ' { "uri": "/filter_func_modulo*", "filter_func": "function(vars); return tonumber(vars.arg_test_query_param) % 2 == 0; end", "upstream": { "type": "roundrobin", "nodes": { "httpbin.org": 1 } }, "plugins": { "proxy-rewrite": { "uri": "/get" } } }' ``` Test the route: - This fails because 1 is odd (`1 % 2 != 0`) ```bash curl localhost:9080/filter_func_modulo?test_query_param=1 {"error_msg":"404 Route Not Found"} ``` - This works because 1 is even (`1 % 2 == 0`) ```bash curl localhost:9080/filter_func_modulo?test_query_param=2 { "args": { "test_query_param": "2" }, "headers": { "Accept": "*/*", "Host": "localhost", "User-Agent": "curl/8.5.0", "X-Amzn-Trace-Id": "Root=1-679a6273-1640eed1461de3267938d3ad", "X-Forwarded-Host": "localhost" }, "origin": "172.19.0.1, X.X.X.X", "url": "http://localhost/get?test_query_param=2"; } ``` The example can be extended to also sanitize/validate the parameter. -- This is an automated message from the Apache Git Service.
