8.Python编写登录接口

from flask import Flask,request,jsonify,session

USERNAME = ‘admin‘
PASSWORD = ‘123456‘
VERIFICATIONCODE = ‘111111‘

app = Flask(__name__)
app.secret_key=‘pithy‘

@app.route(‘/loginNancy‘,methods=[‘GET‘,‘POST‘])
def loginNancy():
    error = None
    if request.method == ‘POST‘:
        if request.form[‘username‘] != USERNAME:
            error = ‘Invalid username‘
        elif request.form[‘password‘] !=PASSWORD:
            error = ‘Invalid password‘
        elif request.form[‘verificationCode‘] != VERIFICATIONCODE:
            error = ‘Invalid verificationCode‘
        else:
            session[‘logged_in‘] = True
            return jsonify({‘code‘:‘200‘,‘msg‘:‘success‘})
        return jsonify({‘code‘:‘400‘,‘msg‘:‘error‘})



if __name__ == ‘__main__‘:　　　　　　　　　　#若不加host=‘0.0.0.0‘则无法通过ip访问接口，只能通过127.0.0.1或者localhost访问

app.run(debug=True,host=‘0.0.0.0‘)         #debug=True，调试模式，修改代码中的输出后，可以自动重载代码并显示调试信息
