Use the FLASK-API library to implement the effective method of data serialization and back-sequentialization
Flask-API is an extension of the Flask framework. It provides a simple way to create RESTFUL API, including data serialization and dependent serialization.The following is a Chinese knowledge article about how to use the Flask-API library to achieve a effective method of data serialization and back-to-order.
The Flask-API library is designed to simplify the process of developers created the API in the Flask framework. It provides some powerful tools and functions to process HTTP requests and responses, including data serialization and derivativeization.
Before using the FLASK-API library to achieve data serialization and desequentization, we need to install Flask and Flask-API libraries first.You can use the PIP command to install:
pip install flask
pip install flask-api
After the installation is completed, we can start writing code.Below is a simple example, showing how to use the Flask-API library to achieve data serialization and desertile:
python
from flask import Flask
from flask_api import FlaskAPI, status
app = Flask(__name__)
api = FlaskAPI(app)
class User(object):
def __init__(self, name, age):
self.name = name
self.age = age
@api.route('/user/', methods=['GET', 'POST'])
def user_list():
if request.method == 'POST':
user = User(request.data.get('name'), request.data.get('age'))
# Execute the operation of saving users
return '', status.HTTP_201_CREATED
elif request.method == 'GET':
# 表 operation of the user list
Return [{'name': 'Zhang San', 'Age': 20},
{'name': 'Li 4', 'Age': 25},
{'name': 'Wang Five', 'Age': 30}]
if __name__ == '__main__':
app.run(debug=True)
In the above code, we first define a `User` class as a data model, which contains the` name` and `age` attributes.Next, we use the@API.ROUTE` decorative and `user_list` function to create an API endpoint`/user/`, which supports get and post requests.
When receiving the post request, we obtain the user's `name` and` age` from the request data, create an `User` object and perform the operation of saving the user.Then, we returned an empty response and status code 201 to represent the success.
When receiving a GET request, we return a JSON response containing the user list, each of which contains the key value pair of the `name` and` age`.
Through the above examples, we can see that it is very simple to use the Flask-API library to achieve data serialization and backlording.We only need to define the data model, and then obtain the data of the request through the `data` attribute of the request object, and process it accordingly.
It is worth noting that the above example code is just a basic demonstration. In actual situations, the code needs to be improved according to specific needs, such as adding database operations and verification data.
In terms of configuration, the Flask-API library does not have specific configuration requirements, and it is consistent with the configuration method of the Flask framework.You can add related configurations to Flask's configuration file, such as turning on debugging mode and setting database connection information.
To sum up, using the FLASK-API library is an effective way to achieve data serialization and desequentization.By defining data models and tools provided by using Flask-API, we can easily handle the data serialization and derivativeization tasks in HTTP requests and responses.
