I'm trying to combine requests from two services in one endpoint.
The first returns the list of users, like this:
{
"data": [
{ "id": 1, "name": "first", "photo": "employee_photos/key1.png" },
{ "id": 2, "name": "second", "photo": null },
{ "id": 3, "name": "third", "photo": "employee_photos/key3.png" }
]
}
The second is supposed to receive the POST request with the JSON listing photo keys to get the required version URLs.
Request:
{
"keys": [ "employee_photos/key1.png", "employee_photos/key3.png" ],
"versions": [ "small", "large" ]
}
I created a small Lua script to process the response of the first request and collect the list of keys. It looks like this:
function post_employees(request, employeesResponse)
local resp = employeesResponse.load()
local data = resp:data():get("data")
local photo_keys = {}
for i = 0, data:len() - 1, 1 do
local rec = data:get(i)
local id = rec:get("id")
local photo = rec:get("photo")
if photo then
table.insert(photo_keys, photo)
end
end
resp:data():set("photos", table.concat(photo_keys, ","))
end
But then... I can't find a way to use this list of keys in the second request. Is it even possible?

I have followed multiple documentation but I couldn't receive all the metrics from my JSON file to Influxdb.

what I have tried :
My telegraf.conf is like this
data_format = "json_v2"
[[inputs.file.json_v2]]
[[inputs.file.json_v2.object]]
path = "apCumulativeReport"
disable_prepend_keys = true
tags = ["cumulativeReportBins_binStartTime"]
[[inputs.file.json_v2.object.field]]
path = "cumulativeReportBins_apCumulativeBinNetworksViews_pci"
type = "int"
Ideally I have to receive all the PCI values from the array but I can see only second element in each PCI array in InfluxDB.
Can someone identify what mistake I'm doing here.
So I am trying to write a Jenkins job using groovy to fetch me some data
The data inside the variable answer after the 3rd line would be some like
[
{
"endIpAddress": "11.21.115.9",
"id": "blabla1",
"name": "blabla",
"resourceGroup": "stg",
"startIpAddress": "11.12.115.9",
"type": "blablafirewallRules"
},
{
"endIpAddress": "1.2.15.9",
"id": "blabla2",
"name": "function1-blabla",
"resourceGroup": "stg",
"startIpAddress": "1.2.15.9",
"type": "blablafirewallRules"
},
{
"endIpAddress": "7.7.7.7",
"id": "blabla2",
"name": "function2-blabla",
"resourceGroup": "stg",
"startIpAddress": "7.7.7.7",
"type": "blablafirewallRules"
},
.
.
.
.
]
What id like to do is to build a list or a 2-dimentions-array that would parse this json and the it will hold all the startipaddress of all the items where name contains "function", so based on this JSON, the data should be
desiredData[0] = [function1-blabla, 1.2.15.9]
desiredData[1] = [function2-blabla, 7.7.7.7]
Up until now I wasn't using JsonSlurper and I was manipulating the text and building the array which is pretty stupid thing to do since this is kind of what JSON is all about I guess.
import groovy.json.JsonSlurper
command = "az mysql server firewall-rule list --resource-group ${rgNameSrvr} --server-name ${BLA} --output json"
answer = azure.executeAzureCliCommand(command, "BLA")
def jsonSlurper = new JsonSlurper()
def json = new JsonSlurper().parseText(answer)
def data = json.findAll{ it.name =~ /^function/ }.collectEntries{ [it.name, it.startIpAddress] }
Code above returns map where key=name and value=ip
If you want 2dim array:
def data = json.findAll{ it.name =~ /^function/ }.collect{ [it.name, it.startIpAddress] }
I have a performance issue in my application. I would like to gather some ideas on what I can do to improve it. The application is very easy: I need to add values inside a nested table to get the total an user wants to pay out of all the pending payments. The user chooses a number of payments and I calculate how much it is they will pay.
This is what I have:
jsonstr = "{ "name": "John",
"surname": "Doe",
"pending_payments": [
{
"month": "january",
"amount": 50,
},
{
"month": "february",
"amount": 40,
},
{
"month": "march",
"amount": 45,
},
]
}"
local lunajson = require 'lunajson'
local t = lunajson.decode(jsonstr)
local limit -- I get this from the user
local total = 0;
for i=1, limit, 1 do
total = total + t.pending_payments[i].amount;
end;
It works. At the end I get what I need. However, I notice that it takes ages to do the calculation. Each JSON has only twelve pending payments (one per month). It is taking between two to three seconds to come up with a result!. I tried in different machines and LUA 5.1, 5.2., 5.3. and the result is the same.
Can anyone please suggest how I can implement this better?
Thank you!
For this simple string, try the test code below, which extracts the amounts directly from the string, without a json parser:
jsonstr = [[{ "name": "John",
"surname": "Doe",
"pending_payments": [
{
"month": "january",
"amount": 50,
},
{
"month": "february",
"amount": 40,
},
{
"month": "march",
"amount": 45,
},
]
}]]
for limit=0,4 do
local total=0
local n=0
for a in jsonstr:gmatch('"amount":%s*(%d+),') do
n=n+1
if n>limit then break end
total=total+tonumber(a)
end
print(limit,total)
end
I found the delay had nothing to do with the calculation in LUA. It was related with a configurable delay in the retrieval of the limit variable.
I have nothing to share here related to the question asked since the problem was actually in an external element.
Thank #lfh for your replies.
I'm using a Ruby script to interface with an application API and the results being returned are in a JSON format. For example:
{
"incidents": [
{
"number": 1,
"status": "open",
"key": "abc123"
}
{
"number": 2,
"status": "open",
"key": "xyz098"
}
{
"number": 3,
"status": "closed",
"key": "lmn456"
}
]
}
I'm looking to search each block for a particular "key" value (yzx098 in this example) and return the associated "number" value.
Now, I'm very new to Ruby and I'm not sure if there's already a function to help accomplish this. However, a couple days of scouring the Googles and Ruby resource books hasn't yielded anything that works.
Any suggestions?
First of all, the JSON should be as below: (note the commas)
{
"incidents": [
{
"number": 1,
"status": "open",
"key": "abc123"
},
{
"number": 2,
"status": "open",
"key": "xyz098"
},
{
"number": 3,
"status": "closed",
"key": "lmn456"
}
]
}
Strore the above json in a variable
s = '{"incidents": [{"number": 1,"status": "open","key": "abc123"},{"number": 2,"status": "open","key": "xyz098"},{"number": 3,"status": "closed","key": "lmn456"}]}'
Parse the JSON
h = JSON.parse(s)
Find the required number using map
h["incidents"].map {|h1| h1['number'] if h1['key']=='xyz098'}.compact.first
Or you could also use find as below
h["incidents"].find {|h1| h1['key']=='xyz098'}['number']
Or you could also use select as below
h["incidents"].select {|h1| h1['key']=='xyz098'}.first['number']
Do as below
# to get numbers from `'key'`.
json_hash["incidents"].map { |h| h['key'][/\d+/].to_i }
json_hash["incidents"] - will give you the value of the key "incidents", which is nothing but an array of hash.
map to iterate thorough each hash and collect the value of 'key'. Then applying Hash#[] to each inner hash of the array, to get the value of "key". Then calling str[regexp], to get only the number strings like '098' from "xyz098", finally applying to_i to get the actual integer from it.
If the given hash actually a json string, then first parse it using JSON::parse to convert it to a hash.Then do iterate as I said above.
require 'json'
json_hash = JSON.parse(json_string)
# to get values from the key `"number"`.
json_hash["incidents"].map { |h| h['number'] } # => [1, 2, 3]
# to search and get all the numbers for a particular key match and take the first
json_hash["incidents"].select { |h| h['key'] == 'abc123' }.first['number'] # => 1
# or to search and get only the first number for a particular key match
json_hash["incidents"].find { |h| h['key'] == 'abc123' }['number'] # => 1
I need to extract some data from a JSON response i'm serving up from curb.
Previously I wasn't calling symbolize_keys, but i thought that would make my attempt work.
The controller action:
http = Curl.get("http://api.foobar.com/thing/thing_name/catalog_items.json?per_page=1&page=1") do|http|
http.headers['X-Api-Key'] = 'georgeBushSucks'
end
pre_keys = http.body_str
#foobar = ActiveSupport::JSON.decode(pre_keys).symbolize_keys
In the view (getting undefined method `current_price' )
#foobar.current_price
I also tried #foobar.data[0]['current_price'] with the same result
JSON response from action:
{
"data": {
"catalog_items": [
{
"current_price": "9999.0",
"close_date": "2013-05-14T16:08:00-04:00",
"open_date": "2013-04-24T11:00:00-04:00",
"stuff_count": 82,
"minimum_price": "590000.0",
"id": 337478,
"estimated_price": "50000.0",
"name": "This is a really cool name",
"current_winner_id": 696969,
"images": [
{
"thumb_url": "http://foobar.com/images/93695/thumb.png?1365714300",
"detail_url": "http://foobar.com/images/93695/detail.png?1365714300",
"position": 1
},
{
"thumb_url": "http://foobar.com/images/95090/thumb.jpg?1366813823",
"detail_url": "http://foobar.com/images/95090/detail.jpg?1366813823",
"position": 2
}
]
}
]
},
"pagination": {
"per_page": 1,
"page": 1,
"total_pages": 131,
"total_objects": 131
}
}
Please note that accessing hash's element in Rails work in models. To use it on hash, you have to use OpenStruct object. It's part of standard library in rails.
Considering, #foobar has decoded JSON as you have.
obj = OpenStruct.new(#foobar)
obj.data
#=> Hash
But, note that, obj.data.catalog_items willn't work, because that is an hash, and again not an OpenStruct object. To aid this, we have recursive-open-struct, which will do the job for you.
Alternative solution [1]:
#foobar[:data]['catalog_items'].first['current_price']
But, ugly.
Alternative solution [2]:
Open Hash class, use method_missing ability as :
class Hash
def method_missing(key)
self[key.to_s]
end
end
Hope it helps. :)
