根因分析

端点名称拼写错误或路由不存在。

English

The endpoint name is misspelled or the route does not exist.

generic

解决方案

  1. 90% 成功率 Check the defined routes and ensure the endpoint name is correct. 
    print(app.url_map)  # List all routes and endpoints
  2. 95% 成功率 Use the correct endpoint name in url_for. 
    url_for('home')  # Replace 'home' with the actual endpoint

无效尝试

常见但无效的做法:

  1. Adding a random URL parameter to the url_for function. 80% 失败

    The endpoint still does not exist; parameters only work for existing routes.

  2. Using the function name instead of the endpoint name incorrectly. 60% 失败

    If the endpoint is explicitly set, the function name may not match.
