[Python] 设置 Flask 跨域请求

方法一

首先允许跨域

from flask_cors import CORS
 
app = Flask(__name__)
CORS(app, supports_credentials=True)
           

然后加入请求头

resp = jsonify(data)
resp.headers['Access-Control-Allow-Origin'] = '*'
return resp
           

方法二

from flask_cors import CORS
 
app = Flask(__name__)
CORS(app, resources=r'/*')
