I have the following code
log(config.render())
However if I have passwords in the config then they'll appear in log. Is there easy way to eliminate this? I am looking for something like that
log(config.map { if ("password" in it.key.toLowerCase()) "***" else it.value }
.render())
For now the only clear solution is to do like this
val contentHiddenValue = ConfigValueFactory.fromAnyRef("***", "Content hidden")
log.info(config.root()
.withoutKey("security")
.withValue("security", contentHiddenValue)
.render())
The obvious disadvantage is that it hides only exact config subtree

I kind of feel stupid for asking this, but haven't been able to find a way to get the key of a JSON value. I know how to retrieve the key if I have an iterator of the object. I also know of operator[].
In my case the key is not a known value, so can't use get(const char *key) or operator[]. Also can't find a getKey() method.
My JSON looks like this:
{Obj_Array: [{"122":{"Member_Array":["241", "642"]}}]}
For the piece of code to parse {"122":{"Member_Array":["241", "642"]}} I want to use get_key()-like function just to retrieve "122" but seems like I have to use an iterator which to me seems to be overkill.
I might have a fundamental lack of understanding of how jsoncpp is representing a JSON file.
First, what you have won't parse in JsonCPP. Keys must always be enclosed in double quotes:
{"Obj_Array": [{"122":{"Member_Array":["241", "642"]}}]}
Assuming that was just an oversight, if we add whitespace and tag the elements:
{
root-> "Obj_Array" : [
elem0-> {
key0-> "122":
val0-> {
key0.1-> "Member_Array" :
val0.1-> [
elem0.1.0-> "241",
elem0.1.1-> "642" ]
}
}
]
}
Assuming you have managed to read your data into a Json::Value (let's call it root), each of the tagged values can be accessed like this:
elem0 = root[0];
val0 = elem0["122"]
val0_1 = val0["Member_Array"];
elem0_1_0 = val0_1[0];
elem0_1_1 = val0_1[1];
You notice that this only retrieves values; the keys were known a priori. This is not unusual; the keys define the schema of the data; you have to know them to directly access the values.
In your question, you state that this is not an option, because the keys are not known. Applying semantic meaning to unknown keys could be challenging, but you already came to the answer. If you want to get the key values, then you do have to iterate over the elements of the enclosing Json::Value.
So, to get to key0, you need something like this (untested):
elem0_members = elem0.getMemberNames();
key0 = elem0_members[0];
This isn't production quality, by any means, but I hope it points in the right direction.
Is there a way to disable the 'remove-the-plural-s' feature in Postgraphile?
I have a table OS in my database and am using the very awesome Postgraphile library to create a GraphQL interface for free. Everything is great, but Postgraphile is truncating my table name, thinking it is plural. So I get allOs instead of allOses and createO, updateO, etc...
I tried:
Adding an underscore after the table name, and then it just retains the entire thing with an underscore.
Adding an underscore (O_S) and then the plural has capital-s allOS but the singular is O_
A smart comment specifying E'#name os' but it still drops the s
A smart comment specifying E'#name oss' which then pluralizes correctly allOsses (haha) and keeps both for the singular oss
PS in case you see this Benjie/other contributors, your documentation is incredible and the library will save me months of work.
This change is performed by PostGraphile's inflector; however it doesn't always get it right (e.g. in this case) but fortunately it's possible to override it with a small plugin.
In this case, it's probably best to add specific exceptions to the pluralize and singularize functions; you can do this using makeAddInflectorsPlugin from our inflection system. Be sure to pass true as the second argument so that the system knows you're deliberately overwriting the inflectors.
const { makeAddInflectorsPlugin } = require('graphile-utils');
module.exports = makeAddInflectorsPlugin(oldInflectors => ({
pluralize(str) {
if (str.match(/^os$/i)) {
return str + 'ses';
}
return oldInflectors.pluralize(str);
},
singularize(str) {
if (str.match(/^osses$/i) {
return str.substr(0, 2);
}
return oldInflectors.singularize(str);
}
}), true);
I'm glad you're enjoying PostGraphile 🤘
I am trying to show the "sgv" value on a Dashing / Smashing dashboard widget. Ultimately I would also like to show the "direction" value as well. I am running into problems pulling that precise value down which changes every 3 to 5 minutes. I have already been able to mirror the exact string using the following:
require 'net/http'
require 'rest-client'
require 'json'
url = "https://dnarnianbg.herokuapp.com/api/v1/entries/current.json"
response = RestClient.get(url)
JSON.parse(response)
# :first_in sets how long it takes before the job is first run. In this case, it is run immediately
current_nightscout = 0
SCHEDULER.every '5m' do
last_nightscout = current_nightscout
current_nightscout = response
send_event('nightscout', { current: current_nightscout, last: last_nightscout })
end
I have also searched the archives several times. I don't wish to write this to a file like this one shows and the duplicate question has been deleted or moved.
I realize that the JSON.parse(response) is just going to parse out whatever I tell it the response equals, but I don't know how to get that response to equal SGV. Maybe the solution isn't in the RestClient, but that is where I am lost.
Here is the JSON URL: http://dnarnianbg.herokuapp.com/api/v1/entries/current.json
EDIT: The output of that link is something like this:
[{"_id":"5ba295ddb8a1ee0aede71822","sgv":87,"date":1537381813000,"dateString":"2018-09-19T18:30:13.000Z","trend":4,"direction":"Flat","device":"share2","type":"sgv"}]
You need something like response[0]["sgv"] which should return 52 if you end up with many items in the list you will need to iterate over them.
The best thing you can do is to break your problem down into easier parts to debug. As you are having problems accessing some JSON via an API you should make a simple script which only does the function you want in order to test it and see where the problem is.
Here is a short example you can put into a .rb file and run;
#!/usr/bin/ruby
require 'open-uri'
require 'json'
test = JSON.parse(open("https://dnarnianbg.herokuapp.com/api/v1/entries/current.json", :read_timeout => 4).read)
puts test[0]["sgv"]
That should return the value from sgv
I realise that short sweet example may be little use as a learner so here is a more verbose version with some comments;
#!/usr/bin/ruby
require 'open-uri'
require 'json'
# Open the URL and read the result. Time out if this takes longer then 4 sec.
get_data = open("https://dnarnianbg.herokuapp.com/api/v1/entries/current.json", :read_timeout => 4).read
# Parse the response (get_data) to JSON and put in variable output
output = JSON.parse(get_data)
# Put the output to get the 'sgv figure'
p output[0]["sgv"]
It always pays to manually examine the data you get back, in your case the data looks like this (when make pretty)
[
{
"_id": "5ba41a0fb8a1ee0aedf6eb2c",
"sgv": 144,
"date": 1537481109000,
"dateString": "2018-09-20T22:05:09.000Z",
"trend": 4,
"direction": "Flat",
"device": "share2",
"type": "sgv"
}
]
What you actually have is an Array. Your server returns only 1 result, numbered '0' hence you need [0] in your p statement. Once you have accessed the array id then you can simply use the object you need as [sgv]
If your app ever returns more than one record then you will need to change your code to read all of the results and iterate over them in order to get all the values you need.
Here is the final code that made it work
require 'net/http'
require 'json'
require 'rest-client'
# :first_in sets how long it takes before the job is first run. In this case, it is run immediately
current_nightscout = 0
SCHEDULER.every '1m' do
test = JSON.parse(open("https://dnarnianbg.herokuapp.com/api/v1/entries/current.json", :read_timeout => 4).read)
last_nightscout = current_nightscout
current_nightscout = p test[0]["sgv"]
send_event('nightscout', { current: current_nightscout, last: last_nightscout })
end
I can probably eliminate require 'rest-client' since that is no longer being used, but it works right now and that is all that matters.
I am trying to create this URL link:
mysite.com/Vote/2/Learn-to-code
Where
area = vote,
id = 2,
topicURL = Learn-to-code
In my routing, I have this to handle this URL pattern:
context.MapRoute(
"Topic",
"Vote/{id}/{topicURL}",
new { controller = "Topic", action = "TopicAnswers" },
new[] { "eus.UI.Areas.Vote.Controllers"}
);
But I am having trouble generating the URL link. Here's my attempt:
#Html.ActionLink("ViewBag.TopicTitle", "TopicAnswers", new { area = "Vote", controller = "Topic", id = ViewBag.TopicId, topicURL = #ViewBag.TopicURL })
First question is: How do I use ViewBag.TopicTitle? If I remove the quotes, it gives red squiggly error. I put the quotes in just so I could run the app to see what URL this generates.
It generates a monster URL.
mysite.com/Vote/Topic/TopicAnswers/2?url=Learn-to-code
However, the URL actually works. But I would really like to create my short and clean looking URL.
mysite.com/Vote/2/Learn-to-code
Any tips greatly appreciated, gracias.
Ok, I did this and it works. This is so simple to read and understand.
#ViewBag.TopicTitle
Is there any good reason why I should attempt to use #Html.ActionLink(...). That just feels like spaghetti.
For starters, why do they place the parameters ("text", action, controller) in this order? That is such a twisty path. This is far more natural to think of:
(controller, action, "text") ... is it not?
Not only easy ones like .com or .net, but also, .co.uk, .fr, .gov.rw ... ?
Should I really make a huge mapping "tld to relevant whois server", or is there an easier way ?
http://php.net/manual/en/function.checkdnsrr.php
if (checkdnsrr('test.nl', 'A')) // or use ANY or for other see above link
{
echo 'Domain exists';
}
else
{
echo 'Domain does not exist';
}
http://whois.net/ any good?
PHP:
$URL = "http://www.dotnetindex.com/articles/5261-Article--AJAX-Tips-and-Tricks.asp";
$PARSED_URL = parse_url($URL);
$DOMAIN = $PARSED_URL['host'];
$ip = gethostbyname($DOMAIN);
if($ip===$DOMAIN)
{
echo "Url does not exist";
}
else
{
echo "Url exists";
}
Do you want to know if the domain is registered, or if it's actually present in the DNS ?
If the former, then whois based approaches are the only viable way, and even then you'll run into massive issues parsing the highly varied output from the various TLDs whois servers.
If the latter, a simple DNS lookup will suffice.
You may have to try different services:
This one seems to work for a lot more than the standard Whois:
http://whois.domaintools.com/
Works for .co.uk and .fr as well as the standard ones
