好吧，我以前也问过这个问题。但是，当我问它时，我对 python 和应用程序引擎的了解有限。这很可能是我过去未能实现这一点的原因。我正在尝试根据用户名使每个配置文件都是唯一的。

任何人，在我深入研究之前，我都会抛出我的个人资料处理程序，该处理程序目前只处理当前登录的用户：

class Profile(MainHandler):
    def get(self):
        if self.user:
            current_user = str(self.user.name)
            key = ''
            imgs  = db.GqlQuery("select * from Profile_Images WHERE name =:1", current_user)
            team_name  = db.GqlQuery("select * from Teams WHERE name =:1", current_user)
            team_images  = db.GqlQuery("select * from Teamimg WHERE user =:1", current_user)
        for clan in team_name:
                name1 = clan.team_name_anycase
        for image in team_images:
            team_imagee = image.key()
        if self.user:
            for img in imgs:
                key = img.key()
            self.render('profile.html', team_img = team_imagee, team_name = name1, profile_image = key, username = self.user.name, email = self.user.email, firstname = self.user.first_name, last_name = self.user.last_name, country = self.user.country)
        else:
            self.redirect('/register')

此处理程序通过 ('profile', Profile) 映射。

到目前为止，我所了解的是，我需要将用户名通过 URL 传递到配置文件处理程序中，然后使用该用户名作为标识符从数据库中提取数据。

我在 stackoverflow 上看到的内容是('profile/<profile_id>', Profile). 我已经搞砸了一段时间，但似乎尾随用户名（例如 localhost:8080/profile/admin）出现 404 错误。我会假设我的映射失败，或者变量（即用户名）无法与配置文件处理程序交互。

有人可以帮我吗？我确信我拥有它，但它失败了。

YAML 文件：

application: suitegamer
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /static
  static_dir: static

- url: /img
  static_dir: img

- url: /.*
  script: main.app

libraries:
- name: jinja2
  version: latest

- name: PIL
  version: "1.1.7"

主处理器：

class MainPage(MainHandler):
    def get(self):
    if self.user:
            self.render('index.html', username = self.user.name, firstname = self.user.first_name)
        else:
            self.render('index.html')

    def post(self):
    username = self.request.get('username').lower()
        password = self.request.get('password')

        u = User.login(username, password)
        if u:
            self.login(u)
            self.redirect('/news_page')
        else:
            msg = 'Invalid login.'
            self.render('login.html', error = msg)

映射：

app = webapp2.WSGIApplication([('/', MainPage),
                               ('/logout', Logout),
                               ('/img', GetImage),
                               ('/register', Register),
                               ('/welcome', Welcome),
                               ('/news_page', News_Page),
                               ('/profile', Profile),
                               ('/edit_profile', Edit_Profile),
                               ('/change_profile_image', Change_Profile_Image),
                               ('/found_a_team', Found_Team),
                               ('/team_main', Team_Main),
                               ('/edit_team_main', Edit_Team_Main),
                               ('/edit_team_image', Edit_Team_Image)],
                              debug=True)

测试配置文件处理程序：

class Profile(MainHandler):
    def get(self, profile_id):
        profile_id = 'admin'
        if self.user:
            key = ''
            imgs  = db.GqlQuery("select * from Profile_Images WHERE name =:1", profile_id)
            team_name  = db.GqlQuery("select * from Teams WHERE name =:1", profile_id)
            team_images  = db.GqlQuery("select * from Teamimg WHERE user =:1", profile_id)
        for clan in team_name:
                name1 = clan.team_name_anycase
        for image in team_images:
            team_imagee = image.key()
        if self.user:
            for img in imgs:
                key = img.key()
            self.render('profile.html', team_img = team_imagee, team_name = name1, profile_image = key, username = self.user.name, email = self.user.email, firstname = self.user.first_name, last_name = self.user.last_name, country = self.user.country)
        else:
            self.redirect('/register')

图像处理程序：

class GetImage(MainHandler):
    def get(self):
        img = db.get(self.request.get("entity_id"))
        self.response.out.write(img.image)

映射到 ('/img', GetImage)

映射应如下所示：

('/profile/(.*)/?', Profile)

并且您的 Handlers get 函数应该采用一个参数，该参数将是配置文件 ID/名称

class Profile(MainHandler):
    def get(self, profile_id):
        # do something with the profile id...

我认为您应该对文档进行更深入的了解。
例如这里：https ://developers.google.com/appengine/docs/python/tools/webapp/running
