烧瓶机动性因Gunicorn而失效

gunicorn flask python

contrariwise · 技术社区 · 8 年前

我正在使用 Flask-Mobility 根据浏览器呈现不同的模板。

在我的本地机器上一切都很好,但在服务器上,我得到了 AttributeError: 'Request' object has no attribute 'MOBILE' 我正在使用 gunicorn

当我测试应用程序时,只将其作为python实例运行,没有gunicorn和worker等,它运行得很好。我看到烧瓶的流动性 @app.before_request 我猜当我使用Gunicorn时,这没有被处理。

失败的线路是:

if request.MOBILE == True:

ERROR in app: Exception on /content/3/intro-to-genetics-1/1/baby-ball [GET]

我已经找出了问题所在。问题不在于古尼康,而在于使用蓝图。我修改了 Flask-Mobility 的 Mobility __init__ def init_app()

if blueprint is not None:
    @blueprint.before_app_request
    def before_app_request():
        ctx = stack.top
        if ctx is not None and hasattr(ctx, 'request'):
            self.process_request(ctx.request)

因此,不是将库初始化为 Mobility(app) ,我用初始化 Mobility(app, blueprint) app 在两种不同的情况下,通过偶然事件,它起了作用。
