Python的RESTAPI键和值

我知道有几种方法可以在Python上为REST API消费目的公开数据。然而，我使用的两种方法似乎在为结果值生成键方面存在问题。以下是我用来构建REST API的两种方法：

第一种方法

from flask import Flask, jsonify
from flaskext.mysql import MySQL

mysql = MySQL()
app = Flask(__name__)

app.config['MYSQL_DATABASE_HOST'] = 'localhost'
app.config['MYSQL_DATABASE_USER'] = 'user'
app.config['MYSQL_DATABASE_PASSWORD'] = 'fakepassword'
app.config['MYSQL_DATABASE_DB'] = 'router'

mysql.init_app(app)

@app.route('/api/v1/routerstatus', methods=['GET'])
def get():
        cursor = mysql.connect().cursor()
        cursor.execute('SELECT * FROM dm_routerstatus ORDER BY 
status_update_time DESC LIMIT 100;')
        rv = cursor.fetchall()
        return jsonify(rv)

if __name__ == '__main__':
        app.run(host='0.0.0.0')
        app.run(debug=True)

from flask import Flask, jsonify, request
from flask_restful import Resource, Api
from json import dumps
from flaskext.mysql import MySQL

*SKIPPED THE DB CREDENTIALS*

mysql = MySQL()
app = Flask(__name__)
api = Api(app)

mysql.init_app(app)

class Router(Resource):
    def get(self):
        conn = mysql.connect().cursor()
        query = cursor.execute('SELECT * FROM dm_routerstatus ORDER BY 
        status_update_time DESC LIMIT 100;')
        result = {'data': [i[0] for i in query.cursor.fetchall()]}
        return jsonify(result)

api.add_resource(Router, '/api/v1/routerstatus')

if __name__ == '__main__':
        app.run(host='0.0.0.0', port=5000)
        app.run(debug=True)

第二种方法

from flask import Flask, jsonify
from flaskext.mysql import MySQL

mysql = MySQL()
app = Flask(__name__)

app.config['MYSQL_DATABASE_HOST'] = 'localhost'
app.config['MYSQL_DATABASE_USER'] = 'user'
app.config['MYSQL_DATABASE_PASSWORD'] = 'fakepassword'
app.config['MYSQL_DATABASE_DB'] = 'router'

mysql.init_app(app)

@app.route('/api/v1/routerstatus', methods=['GET'])
def get():
        cursor = mysql.connect().cursor()
        cursor.execute('SELECT * FROM dm_routerstatus ORDER BY 
status_update_time DESC LIMIT 100;')
        rv = cursor.fetchall()
        return jsonify(rv)

if __name__ == '__main__':
        app.run(host='0.0.0.0')
        app.run(debug=True)

from flask import Flask, jsonify, request
from flask_restful import Resource, Api
from json import dumps
from flaskext.mysql import MySQL

*SKIPPED THE DB CREDENTIALS*

mysql = MySQL()
app = Flask(__name__)
api = Api(app)

mysql.init_app(app)

class Router(Resource):
    def get(self):
        conn = mysql.connect().cursor()
        query = cursor.execute('SELECT * FROM dm_routerstatus ORDER BY 
        status_update_time DESC LIMIT 100;')
        result = {'data': [i[0] for i in query.cursor.fetchall()]}
        return jsonify(result)

api.add_resource(Router, '/api/v1/routerstatus')

if __name__ == '__main__':
        app.run(host='0.0.0.0', port=5000)
        app.run(debug=True)

如何在不键入数据库中找到的每一列标题的情况下获取键名？提前感谢您的回复。

使用DictCursor（

MySQLdb.cursors.DictCursor

）

好的。现在我明白了。谢谢我只需要在查询行中添加dict。让我们设置第二个方法，例如：

res=[dict（（conn.description[i][0]，value）for i，value in enumerate（row））for conn.fetchall（）中的row]
