Falsk解决后端跨域问题

1. 先下载对应的包

   pip install flask_cors

2. 导入包

   from flask_cors import CORS

3. 创建app后中写入

   CORS(app, resources=r'/*')

示例代码如下：

 1 from flask import Flask
 2 from flask_cors import CORS
 3 from flask_mail import Mail
 4 from config import APP_ENV, config,API_VERSION
 5 
 6 mail = Mail()
 7 
 8 def create_app():
 9     """
10     工厂函数，创建APP实例
11     :return app实例
12     """
13     setupLogging(config[APP_ENV].LOGGING_LEVEL)
14 
15     app = Flask(__name__)
16     app.config.from_object(config[APP_ENV])
17 
18     CORS(app, resources=r'/*')
19 
20     app.after_request(after_request)
21 
22     # 创建Redis数据库连接对象
23     global redis_conn
24     redis_conn = redis.StrictRedis(host=config[APP_ENV].REDIS_HOST, port=config[APP_ENV].REDIS_PORT)
