I have a single string like with multiples json:
{"operation": {"status": true, "limit": 100}}{"operation1": {"customer": "Jhon", "sum": 20, "time": "2019-02-13T10:00:00.000Z"}}{"operation1": {"customer": "Henry", "sum": 90, "time": "2019-02-13T11:00:00.000Z"}}
I would like to get a list of json to be able to process each json as an individual object.
You can use json library with streaming support. E.g.
(require '[cheshire.core :as json])
(->> "{\"operation\": {\"status\": true, \"limit\": 100}}{\"operation1\": {\"customer\": \"Jhon\", \"sum\": 20, \"time\": \"2019-02-13T10:00:00.000Z\"}}{\"operation1\": {\"customer\": \"Henry\", \"sum\": 90, \"time\": \"2019-02-13T11:00:00.000Z\"}}"
char-array
io/reader
json/parsed-seq
(take 2))
returns
({"operation" {"status" true, "limit" 100}}
{"operation1" {"customer" "Jhon", "sum" 20, "time" "2019-02-13T10:00:00.000Z"}})
I had to clean up your data. You may need to clarify where it is coming from so your question is more understandable (in context).
(ns tst.demo.core
(:use demo.core tupelo.core tupelo.test)
(:require
[tupelo.core :as t]
[tupelo.string :as ts]))
; NOTE: I added square-brackets to wrap everyting in an array, and I also
; had to add commas between the array entries
(def data
"[ {'operation': {'status': true, 'limit': 100}},
{'operation1': {'customer': 'Jhon', 'sum': 20, 'time': '2019-02-13T10:00:00.000Z'}},
{'operation1': {'customer': 'Henry', 'sum': 90, 'time': '2019-02-13T11:00:00.000Z'}} ] " )
with result
(t/json->edn (ts/quotes->double data)) =>
({:operation {:status true, :limit 100}}
{:operation1
{:customer "Jhon", :sum 20, :time "2019-02-13T10:00:00.000Z"}}
{:operation1
{:customer "Henry", :sum 90, :time "2019-02-13T11:00:00.000Z"}})
This does not deserve to count as an answer beyond the helpful one by @rmcv, but it is too much for just a comment. If useful, @rmcv should feel free to add this context to their answer and I can then delete this answer...
If you want to return the JSON keywords as Clojure keywords then a tweak to that answer is:
;; Emits map with JSON keys as Clojure keywords...
(-> "{\"operation\": {\"status\": true, \"limit\": 100}}{\"operation1\": {\"customer\": \"Jhon\", \"sum\": 20, \"time\": \"2019-02-13T10:00:00.000Z\"}{\"operation1\": {\"customer\": \"Henry\", \"sum\": 90, \"time\": \"2019-02-13T11:00:00.000Z\"}}"
char-array
io/reader
(json/parsed-seq true)
(->> (take 2)))
which returns
({:operation {:status true, :limit 100}}
{:operation1 {:customer "Jhon", :sum 20, :time "2019-02-13T10:00:00.000Z"}})
The true argument to parsed-seq just applies this function to the JSON keywords
(fn [k] (keyword k))
and you can do more complex things with the keyword processing this way, i.e. (not so complex):
(-> "{\"operation\": {\"status\": true, \"limit\": 100}}{\"operation1\": {\"customer\": \"Jhon\", \"sum\": 20, \"time\": \"2019-02-13T10:00:00.000Z\"}}{\"operation1\": {\"customer\": \"Henry\", \"sum\": 90, \"time\": \"2019-02-13T11:00:00.000Z\"}}"
char-array
io/reader
(chesire/parsed-seq (fn [k] (keyword (clojure.string/upper-case k))))
(->> (take 2)))
returns
({:OPERATION {:STATUS true, :LIMIT 100}}
{:OPERATION1 {:CUSTOMER "Jhon", :SUM 20, :TIME "2019-02-13T10:00:00.000Z"}})
