根因分析

两个不同的视图函数使用相同的端点名称或路由注册。

English

Two different view functions are registered with the same endpoint name or route.

generic

解决方案

  1. 95% 成功率 Use unique endpoint names 
    @app.route('/home', endpoint='home')
def home():
    return 'Home'
@app.route('/main', endpoint='main')
def main():
    return 'Main'
  2. 90% 成功率 Combine routes with different methods 
    @app.route('/data', methods=['GET'])
def get_data():
    return 'GET'
@app.route('/data', methods=['POST'])
def post_data():
    return 'POST'

无效尝试

常见但无效的做法:

  1. Changing function name without changing endpoint 70% 失败

    Flask uses endpoint, not function name, for uniqueness.

  2. Using same route for GET and POST without specifying methods 60% 失败

    Can cause conflict if both are same function.
