Flask 使用蓝图接口报错 报 404 not found

    最近在学习flask，然后学习了蓝图时，就简单的使用一下，贴一下简单学习的代码

from flask import Flask,Blueprint,request

app = Flask(__name__)

blue=Blueprint('testLearn',__name__)
app.register_blueprint(blue,url_prefix='/admin')

@blue.route('/learn',methods=['GET','POST'])
def learn():
 if request.method == 'POST':
  return 'hello word'


if __name__ == '__main__':
 app.run()

结果在postman上运行接口，发现接口报404错误

后来百度一下，发现蓝图注册需要写在视图函数之后，改为

from flask import Flask,Blueprint,request

app = Flask(__name__)

blue=Blueprint('testLearn',__name__)


@blue.route('/learn',methods=['GET','POST'])
def learn():
 if request.method == 'POST':
  return 'hello word'
app.register_blueprint(blue, url_prefix='/admin')


if __name__ == '__main__':
 app.run()

运行结果就显示正常
