8.Python编写登录接口

Posted 2020-12-31 廖丹

1.python需安装flask，在命令行窗口输入：pip3 install flask

2.代码如下所示：

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

3.实现效果：
