We are using the MultiSelect syntax of jmespath for this. I have used the JMESPath examples and tester to come up with the query and this is what the query I came up with Now we need to come up with the JMESpath query that we are going to use in ansible json_query filter to get only these elements from on otherwise huge dataset. Print the following fields for each user ( with custom key names)
#JSON QUERY TUTORIAL DOWNLOAD#
Download the preceding JSON users data from the JSON placeholder URL.So now we are going to create a playbook, which is going to do the following operation Let us consider the JSON content given above and try to filter only the following fields for each user using ansible json_query and create a Business card type of data for each user.
#JSON QUERY TUTORIAL HOW TO#
I covered how to Parse JSON file using ansible here Parse JSON data from URL response – using Ansible json_query In this article, we are going to parse JSON response given by the URL directly in case if you would like to read JSON file and parse them with ansible. "catchPhrase": "Proactive didactic contingency", "catchPhrase": "Multi-layered client-server neural-net", JSON Placeholder has a set of JSON endpoints/URLs you can use for testing. This is taken from the JSON Placeholder users endpoint URL. To calculate the total revenue by the visitor, you use the following query: SELECT visitor, SUM (properties-> '.amount') revenue FROM events WHERE properties-> '.amount' > 0 GROUP BY visitor In this tutorial, you have learned about the MySQL JSON data type and how to use it for storing JSON documents in the database. This is the sample data we are going to take for our testing. JSON is lightweight data-interchange format. What is JSON JSON stands for JavaScript Object Notation.
You will also learn how to convert json to xml, html, csv, php array and vice versa. Some Sample JSON for testing – Ansible JSON In this JSON tutorial, you will be able to learn JSON examples with other technologies such as Java, PHP, Python, Ruby, jQuery, AJAX, C, Perl and Jackson. It is more like regex101 we use for Regular expression testing. It has a nice toolset as well, where you could write and test your queries before you try it in realtime. Look at the following screenshot, A Home Page of JMESPATH You can pretty much do everything with JSON It helps you to parse JSON content and filter the elements you want. It is a powerful query language to parse JSON content. Json_query is using the jmespath Query language.
Some Sample JSON for testing – Ansible JSON.What is json_query and how does it work?.
