当我在应用引擎上部署我的应用时，图库可以正常工作（http://mark-smith-app.appspot.com/projects/），但它不能脱机工作..
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/它显示图库但只显示第一个图像时，图库中的其余图像为“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 ，当我用chrome打开它时，它可以正常工作。
我将index4.html中的所有内容复制到我的google应用引擎projects.html中，并更改为css，js和images创建了一个静态目录。
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
我也去了127.0.0.1/projects并进入“查看源代码”并将其复制到html1.txt
我还将index4.html中的“view source”复制到了html2.txt
我从以下python不同脚本得到以下结果：
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，其中库正确显示05.jpg然后你可以看到我点击01和04.jpg，然后回到05.jpg（05.jpg是唯一没有被涂黑的人）。缩略图可以工作。

答案 0 :(得分：2)
鉴于确切原因是什么，几乎不可能从信息中得知，但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，因此如果请求不可能在图像请求进入之前完成，最终浏览器将超时并且不再尝试渲染图像。
查看开发服务器写出的日志会很有用。
