将 Unity WebPlayer 应用程序上传到 Google App Engine 得到 500 服务器错误

Question

我正在参加 Google 应用挑战赛，但我无法让应用在 apppot 域网站上运行。我正在使用 Python 部署应用。需要帮助

app.yaml 文件详情如下

application: abhicorp111
version: 1
runtime: python27
api_version: 1
threadsafe: yes

handlers:


- url: /WebPlayer\.unity3d
  static_files: WebPlayer/WebPlayer.unity3d
  upload: WebPlayer/WebPlayer\.unity3d

- url: .*
  script: main.app

libraries:
- name: webapp2
  version: "2.5.2"

The main.py content

from google.appengine.ext.webapp import template
import webapp2
import os

class MainHandler(webapp2.RequestHandler):
def get(self):

template_values = {
'greetings': 'greetings',
}
path = os.path.join('WebPlayer', 'WebPlayer.html')
self.response.out.write(template.render(path, template_values))



app = webapp2.WSGIApplication([
    ('/', MainHandler)
], debug=True)

从命令行更新后得到 500 服务器错误 应用程序的文件夹结构 我得到的错误 我通过 GAE 日志控制台上传时得到的错误日志

Answer 1

main.py 有语法错误（不正确的缩进）。您需要缩进def get(self):，并进一步缩进get 方法中的代码。就是这样

> IndentationError: expected an indented block

想告诉你。

我建议在上传之前让您的应用在 dev_appserver 本地运行。这将大大缩短开发周期。

Answer 2

来自错误日志：

Could not initialize images API; you are likely missing the Python "PIL" module.

您需要为您的应用程序配置 PIL。从文档的configuring third party libraries 部分，将以下内容添加到您的app.yaml：

libraries:
- name: PIL
  version: latest

在您的代码本身存在一些基本问题之后。 Python 对空白很敏感，任何进入块内的语句都需要缩进，这就是您收到此错误的原因：

文件“E:\GAEGame\WebPlayer\main.py”，第 22 行

def get(self):

  ^

IndentationError: 需要一个缩进块

块内的所有语句都需要缩进；通常的做法是缩进四个空格（不是制表符）。这是您的代码，正确缩进：

from google.appengine.ext.webapp import template
import webapp2
import os

class MainHandler(webapp2.RequestHandler):
    def get(self):
        template_values = {
            'greetings': 'greetings',
        }
        path = os.path.join('WebPlayer', 'WebPlayer.html')
        self.response.out.write(template.render(path, template_values))



app = webapp2.WSGIApplication([
    ('/', MainHandler)
], debug=True)
