Question

我使用flask，当我调用此url时出现此错误：/login 这是我的登录方法：

@app.route('/login')
def login():
    if authenticateForPanel():
        return redirect(url_for("panel"))
    else:
        getParam = request.args.getlist('redirect_uri')
        if getParam:
            ref =getParam[0]
        else:
            ref="/panel"
        return render_template( themesDir + g.blogOptions['active_theme']+'/login.html', blogOptions = g.blogOptions, ref=ref )

追溯：

TemplateNotFound: static/themes/default/login.html

我绝对相信login.html就在那里（static/themes/default/404.html）。为什么会出现这种情况？

Answer 1

您将模板放在错误的位置。来自Flask文档：

Flask将在templates文件夹中查找模板。因此，如果您的应用程序是一个模块，那么该文件夹就在该模块旁边，如果它是一个包，它实际上在您的包中：有关详细信息，请参阅文档：http://flask.pocoo.org/docs/quickstart/#rendering-templates

Answer 2

我认为你不应该先加themesDir。您只将模板的文件名传递给flask，然后它将查找相对于您的python文件的名为templates的文件夹。
