flask_newsapi's Introduction
跨域问题来源于JavaScript的"同源策略",即只有协议+主机名+端口号 (如存在)相同,才允许相互访问。 也就是说JavaScript只能访问和操作自己域下的资源,不能访问和操作其他域下的资源。 跨域问题是针对JS和ajax的,html本身没有跨域问题。 后端解决跨域问题 pip install flask-cors 使用第三方扩展 exts中创建 from flask_cors import CORS cors= CORS() 与app进行绑定即可 cors.init_app(app=app,supports_credentials=True) 蓝图与api配合使用 user_bp = Blueprint('user', __name__) 蓝图绑定api 蓝图注册到app上 api = Api(user_bp) app.register_blueprint(user_bp) # 定义api class xxxxApi(Resource): pass # 绑定路由 api.add_resource(xxxxApi,'/xxxx') 在OAuth协议中,token是在输入了用户名和密码之后获取的,利用这个token可以拥有查看或者操作相应的资源的权限。 有这些权限,是因为服务器知道你是谁以后赋予你的,所以token,其实就是你的一个“代表”,或者说完全能代表你的“通行证”。
