Basic usage of mock server

What is? mock server

Realization mock A service of function

mock server The role of

Nowadays, few business systems exist independently , They more or less need to use the services provided by brother teams or other companies, which causes trouble for our joint debugging and testing
In this case , Our common solution is to build a temporary server, Simulate those services , because flask Rich third-party open source components

initial Flask

The packaging function is not as good as Django perfect , The performance is not as good as Tomado, however Flask Strong expandability , because flask Rich third-party open source components
WSGI Introduce ：
Django Use wsgiref modular

The configuration file

app=Flask(name,template_folder=‘templates’,static_url_path=‘/static/’,static_path=‘/zz’)

• Template path ：template_folder=‘templates’
• Static file path ：static_url_path=‘/static/’
• Static files introduce aliases ：static_path=‘/zz’
• Set up the debugging environment ：app.debug=True( Code changes are automatically updated )
• j Set up json If the encoding format is False Don't use ascii code :app.config[‘JSON_AS_ASCII’]=False
• Set response header information ：Content-Type app.config[‘JSONIFY_MIMETYPE’]=“application/json;charset=utf-8”
  （ Be careful ;charset=utf-8）

Routing system

1. Dynamic transfer parameters

from flask import Flask


app = Flask(__name__)


#  Set a dynamic parameter 

@app.route('/<name>')

def second_flask(name):

    print(name)

    return 'Hello World'

【 be based on flask Framework implementations Mock Server】

• According to the interface documentation , Design Mock Server
• mock server Design - Sign in
  1） The parameter is empty.
  2） The username and password are correct
  3） Wrong username and password
  mockServer It is not a real backend system , You need to make it meet the simulation test requirements of your interface
  post Basic use of the method

# coding:utf-8


from flask import Flask, request

#  establish Flask object 

app = Flask(__name__)


#  The view function 

@app.route('/login', methods=['GET', 'POST'])
def request_flask():
    """post Request parameter prompt """
    #  Get request data , The return data type is bytes: b'{"username": "zz", "password": "123456"}' <class 'bytes'>
    c = request.get_data()
    print(c, type(c))
    #  Get the requested data type , Return to json： {'username': 'zz', 'password': '123456'} <class 'dict'>
    d = request.get_json()
    print(d, type(d))
    #  Get the requested data type , Return to bytes: b'{"username": "zz", "password": "123456"}' <class 'bytes'>
    e = request.data
    print(e, type(e))

    #  obtain json： {'username': 'zz', 'password': '123456'} <class 'dict'>
    f = request.json
    print(f, type(f))
    f1 = request.json['username']
    print(f1)
    return 'Hello world'


if __name__ == '__main__':
    app.run()

post Test code

# coding:utf-8


import requests


data = {
    
    'username': 'zz',
    'password': '123456'
}

url = 'http://127.0.0.1:5000/login'
resp = requests.post(url=url, json=data)
print(resp)

post Method data output

b'{"username": "zz", "password": "123456"}' <class 'bytes'>
{
    'username': 'zz', 'password': '123456'} <class 'dict'>
b'{"username": "zz", "password": "123456"}' <class 'bytes'>
