Using the flask framework to write the bezel

flask The framework has many functions , So today, let's talk about the application in baffle . First, let's talk about the baffle , This word is commonly used in performance testing , That is, the complete test environment has not been completed , Or the cost of testing is high , Such as sending text messages . Then you need to simulate some functions that are not built or costly , This can be done with a baffle , Intuitively, it is to simulate the real environment .

We also have a certain understanding of the baffle , So how to build it , Then follow me , Build a simple baffle

One 、 open python Editor , Here, I use pycharm, Create a project , Whatever it's called , Build one inside run.py

Two 、 Edit code , There needs to be flask Basic students ,  If you don't have one, you can read my previous post about flask Framework Basics

from flask import Flask, session, request, redirect, url_for,Response, jsonify
import json
import time
app = Flask(__name__)
#  Define the interface path 
@app.route('/api/login', methods=['post', 'get'])
def do_login():
    #  The way to judge a request is post still get
    if request.method == "GET":
        fail = {
            "timestamp": (time.asctime()),
            "error": 1
        }
        # get Return if requested fail data 
        return jsonify(fail)
    # post Return if requested success data 
    else:
        success = {
            "data": {
                "user_info": request.get_json()["user_info"],
                "password": request.get_json()["password"]
            },
            #  Time stamp 
            "timestamp": (time.asctime()),
            "success": 1
        }
        #  return json Data in form 
        return jsonify(success)
        
if __name__ == '__main__':
    app.run(debug=True)

3、 ... and 、 Run code

Okay , Such a simple baffle server is OK , It's very simple , Compared with formal business, there is no complicated business processing process , It is a simple process of simulating the return message , Next, let's use requests Let's test it , See how it works

newly build test.py file

Write the code inside

import json
import requests
# GET request 
# requests.get(url, params=None）
# POST request 
url = "http://127.0.0.1:5000/api/login"
data = {
    "user_info": "xiaoli",
    "password": "123456"
}
#  Request header , Here's the message json data , So choose the following form 
headers = {'Content-Type': 'application/json'}
#  Convert a common dictionary type to json type 
data_json = json.dumps(data)
#  among data Parameters are the data sent , That's our json Type data 
res = requests.post(url, data=data_json, headers=headers, json=None)
print(res.text)

Run below , Love once , Take a look at the returned results

The above return indicates that our baffle configuration is successful . In this way, we can return the specified return content as required , Specifically, on this basis, it is OK to modify
