无法查看屏幕上的输出 [英] unable to view output on screen

问题描述

我的代码如下：

my code is as follows :

from flask import Flask
from flaskext.mysql import MySQL

mysql = MySQL()
app = Flask(__name__)
app.config['MYSQL_DATABASE_USER'] = 'root'
app.config['MYSQL_DATABASE_PASSWORD'] = ''
app.config['MYSQL_DATABASE_DB'] = 'OMTSL_QBO'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'
mysql.init_app(app)

@app.route("/")
def hello():
    return "Welcome to Python Flask App!"

@app.route("/Authenticate")
def Authenticate():
    cursor = mysql.connect().cursor()
    cursor.execute("SELECT count(*) from REPORT_SUITE")
    data = cursor.fetchone()
    print data    
    return data

if __name__ == "__main__":
    app.run(debug = True)

我无法在屏幕上查看计数。我得到的错误是TypeError：'长'对象不可调用。请帮助。

i am unable to view the count on screen . The error i am getting is TypeError: 'long' object is not callable.. Please help.

推荐答案

您需要返回字符串或从瓶子视图函数的响应，因为你正在返回 long type flask正在抱怨。详细了解回复此处。

You need to return string or response from flask view function and since you are returning long type flask is complaining. Learn more about responses here.

在你的情况下，只需要执行 return str（data）。

In your case it'll be enough to do return str(data).
