帮我依据下列代码用flask框架建立sqlite3数据库:insert into scores (idx,oppo_type,room_num,name1,oper1,delta1,tot1,name2,oper2,delta2,tot2,ifNo1) values (?,?,?,?,?,?,?,?,?,?,?,?)',[number,AI_type,room,rd_arr[0],player_action,score_add,score,oppo,operation,delta_AI,oppo_score[oppo],check])

基于Flask和SQLite的数据库设计源码
首先,需要安装Flask和SQLite3的Python库。可以使用以下命令进行安装:
```
pip install Flask
pip install sqlite3
```
然后,可以按照以下步骤建立SQLite3数据库:
1. 创建一个名为`app.py`的Python文件,并在其中导入相关库:
```python
from flask import Flask, request, jsonify
import sqlite3
```
2. 创建Flask应用程序,并连接到SQLite3数据库:
```python
app = Flask(__name__)
conn = sqlite3.connect('scores.db')
c = conn.cursor()
```
3. 在`app.py`中添加一个路由,用于接收POST请求并将数据插入到数据库中:
```python
@app.route('/insert', methods=['POST'])
def insert_score():
number = request.form['idx']
AI_type = request.form['oppo_type']
room = request.form['room_num']
rd_arr = [request.form['name1']]
player_action = request.form['oper1']
score_add = request.form['delta1']
score = request.form['tot1']
oppo = request.form['name2']
operation = request.form['oper2']
delta_AI = request.form['delta2']
oppo_score = request.form['tot2']
check = request.form['ifNo1']
c.execute('''INSERT INTO scores (idx,oppo_type,room_num,name1,oper1,delta1,tot1,name2,oper2,delta2,tot2,ifNo1)
VALUES (?,?,?,?,?,?,?,?,?,?,?,?)''',
[number,AI_type,room,rd_arr[0],player_action,score_add,score,oppo,operation,delta_AI,oppo_score,check])
conn.commit()
return jsonify({'message': 'Score added successfully!'})
```
4. 最后,运行应用程序:
```python
if __name__ == '__main__':
app.run(debug=True)
```
完整的`app.py`文件如下所示:
```python
from flask import Flask, request, jsonify
import sqlite3
app = Flask(__name__)
conn = sqlite3.connect('scores.db')
c = conn.cursor()
@app.route('/insert', methods=['POST'])
def insert_score():
number = request.form['idx']
AI_type = request.form['oppo_type']
room = request.form['room_num']
rd_arr = [request.form['name1']]
player_action = request.form['oper1']
score_add = request.form['delta1']
score = request.form['tot1']
oppo = request.form['name2']
operation = request.form['oper2']
delta_AI = request.form['delta2']
oppo_score = request.form['tot2']
check = request.form['ifNo1']
c.execute('''INSERT INTO scores (idx,oppo_type,room_num,name1,oper1,delta1,tot1,name2,oper2,delta2,tot2,ifNo1)
VALUES (?,?,?,?,?,?,?,?,?,?,?,?)''',
[number,AI_type,room,rd_arr[0],player_action,score_add,score,oppo,operation,delta_AI,oppo_score,check])
conn.commit()
return jsonify({'message': 'Score added successfully!'})
if __name__ == '__main__':
app.run(debug=True)
```
在运行应用程序之前,需要先创建一个名为`scores.db`的SQLite3数据库。可以使用SQLite3命令行工具或SQLite3可视化工具,手动创建一个名为`scores`的表,表中包含与`INSERT`语句中的字段相对应的列。例如:
```sql
CREATE TABLE scores (
idx INTEGER PRIMARY KEY,
oppo_type TEXT,
room_num TEXT,
name1 TEXT,
oper1 TEXT,
delta1 INTEGER,
tot1 INTEGER,
name2 TEXT,
oper2 TEXT,
delta2 INTEGER,
tot2 INTEGER,
ifNo1 TEXT
);
```
完成上述步骤后,即可运行应用程序,并使用POST请求向`/insert`路由发送数据,将数据插入到SQLite3数据库中。
