How can we convert from simple JSON using thrift?

edit

To convert from simple JSON to Thrift, you can use the following steps:

1. Create a Thrift definition file (.thrift) that defines the message structure of your data.
2. Generate code from the Thrift definition file using a Thrift compiler.
3. Use the generated code to deserialize the simple JSON data into a Thrift struct.

Here is an example Thrift definition file:

struct User {
  1: i32 id,
  2: string name,
  3: string email,
  4: i32 age,
}

Assuming you have generated the code from this Thrift definition file and have imported the generated code into your project, you can use the following code to convert from simple JSON to Thrift:

import json
from your_project.user import User  # Assume this is the generated code from the Thrift definition file.

data = '{"id": 1, "name": "John", "email": "john@example.com", "age": 30}'
json_data = json.loads(data)

user = User()
user.id = json_data["id"]
user.name = json_data["name"]
user.email = json_data["email"]
user.age = json_data["age"]

In this example, we first load the simple JSON data into a Python dictionary using json.loads(). We then create an instance of the Thrift User struct and set its fields based on the values in the dictionary. This creates a Thrift object that can be used in your application.
