在Python 3.6中读取MySQL数据库中的图片,您可以使用以下步骤:
1. 连接到MySQL数据库。您可以使用Python的MySQL驱动程序,如PyMySQL或mysql-connector-python。
2. 执行SELECT查询来获取图像数据。您需要使用BINARY类型来存储图像数据。
3. 使用Python的Pillow库(也称为PIL)将二进制数据转换为图像。Pillow库可以安装使用pip命令。
以下是一个示例代码片段:
```python
import mysql.connector
from PIL import Image
from io import BytesIO
# 连接到MySQL数据库
cnx = mysql.connector.connect(user='username', password='password',
host='localhost',
database='databasename')
cursor = cnx.cursor()
# 执行SELECT查询
query = ("SELECT image_data FROM images WHERE image_id = %s")
image_id = 1
cursor.execute(query, (image_id,))
# 获取图像数据
image_data = cursor.fetchone()[0]
# 将二进制数据转换为图像
img = Image.open(BytesIO(image_data))
img.show()
# 关闭连接
cursor.close()
cnx.close()
```
请注意,这只是一个示例代码片段。您需要根据您的实际情况进行修改。
