python - 值错误 : invalid literal for int() with base 10 trying to retrieve a query parameter from Google App engine

Question

我在尝试使用 Google App Engine 检索数据时收到以下错误从单个条目到单个页面，例如foob​​ar.com/page/1 将显示来自 id 1 的所有数据:

ValueError: invalid literal for int() with base 10

文件如下:

Views.py

class One(webapp.RequestHandler):    
    def get(self, id):
        id         = models.Page.get_by_id(int(str(self.request.get("id")))) 
        page_query = models.Page.get(db.Key.from_path('Page', id))
        pages      = page_query

        template_values = {
            'pages': pages,
        }

        path = os.path.join(os.path.dirname(__file__), 'template/list.html')
        self.response.out.write(template.render(path, template_values))

网址.py:

(r'/browse/(\d+)/', One),

错误:

Traceback (most recent call last):  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/ext/webapp/__init__.py", line 501, in __call__    handler.get(*groups)  File "/Volumes/foobar/views.py", line 72, in get    id = models.Page.get_by_id(int(str(self.request.get("id"))))ValueError: invalid literal for int() with base 10: ''

Answer 1

将 self.request.get("id") 更改为简单的 id，它已经被传递给您的 get 处理程序。

您拥有的代码仅适用于 /browse/1/?id=1

这样的 URL
