修改下面的代码直到能用为止function denycc if CCDeny then local uri=ngxvaruri CCcount=tonumberstringmatchCCrate CCseconds=tonumberstringmatchCCrate local token = getClientIpuri

function denycc() if CCDeny then local uri = ngx.var.uri local CCrate = ngx.var.limit_rate local CCcount = tonumber(string.match(CCrate, '(.)/')) local CCseconds = tonumber(string.match(CCrate, '/(.)')) local token = getClientIp() .. uri local limit = ngx.shared.limit local req = limit:get(token) local ip = getClientIp() local block = limit:get(ip)

    if block then
        return ngx.exit(444)
    end

    if req then
        if req > CCcount then
            limit:set(ip, 1, DenySeconds)
            return ngx.exit(444)
        else
            limit:incr(token, 1)
        end
    else
        limit:set(token, 1, CCseconds)
    end
end
return false
