照片库适用于 GAE AppSpot,但不适用于 127.0.0.1

photo gallery works on gae appspot but not on 127.0.0.1

本文关键字:适用于 不适用 GAE AppSpot 照片库      更新时间:2023-09-26

当我在应用程序引擎上部署我的应用程序时,图库可以工作(http://mark-smith-app.appspot.com/projects/),但它不能离线工作。

我想让我的画廊使用以下命令:

C:'Python27'python.exe "C:/Program Files/Google/google_appengine/dev_appserver.py" .

当我打开 chrome 并转到 127.0.0.1/projects/时,它显示了图库,但只显示第一张图像,图库中的其余图像都是"黑色"。

我从 http://www.awkwardgroup.com/sandbox/awkward-showcase-a-jquery-plugin/下载了图库

我下载的图库附带了一个示例 index4.html当我使用 chrome 打开它时,它可以工作。

我将 index4.html 中的所有内容复制到我的 google App Engines 项目中.html并更改了 css、js 和图像的静态目录。

这是app.yaml:

application: mark-smith-app
version: 1
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /stylesheets
  static_dir: stylesheets
- url: /images
  static_dir: images
- url: /.*
  script: main.app
libraries:
- name: jinja2
  version: latest

我还转到 127.0.0.1/projects,然后转到"查看源代码"并将其复制到 html1 中.txt

我还将 index4.html 中的"查看源代码"复制到 html2 中.txt

我从以下python不同脚本中得到了以下结果:

f1 = open('html1.txt')
f2 = open('html2.txt')
from difflib import ndiff,IS_CHARACTER_JUNK

delta = ndiff([i.strip()+"'n" for i in f1],[i.strip()+"'n" for i in f2])
for line in delta:
    print line,

输出:

*** Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32. ***

日志如下: 我运行应用程序,单击项目链接转到/projects/页面,图库正确显示 05.jpg然后你可以看到我点击到 01 和 04.jpg,然后回到 05.jpg(05.jpg 是唯一没有被黑掉的)。缩略图虽然有效。

从给定的信息中几乎不可能知道确切的原因是什么,但是开发服务器和生产服务器之间存在一个很大的区别:开发服务器是单线程的,因此,如果在图像请求进入之前无法完成请求,最终浏览器将超时并不再尝试渲染图像。

查看开发服务器写出的日志会很有用。
