根因分析

Flask 需要使用密钥来支持会话。如果未设置 app.secret_key,会话操作会失败。

English

Flask requires a secret key to use sessions. If app.secret_key is not set, session operations fail.

解决方案

  1. 95% 成功率 Set secret_key on the Flask app instance
    app.secret_key = 'your-secret-key'
  2. 95% 成功率 Use os.urandom to generate a secure key
    import os
    app.secret_key = os.urandom(24)

无效尝试

常见但无效的做法:

  1. Setting secret_key to an empty string 90% 失败

    An empty string is not considered a valid secret key.

  2. Using app.config['SECRET_KEY'] = 'mysecret' after first session access 70% 失败

    The secret key must be set before the first session usage.
