打开网络图片并展示

好玩

今天同事问我一个问题,关于nginx location 的问题,在项目现场没有搞出来,又累又饿又冷又烦躁,心想这特么的问题出在哪呢,关于location的定位之前了解过,长时间不用于是忘了.真失望.后来大家都走了,本来没想背电脑回来,于是,背回来吧,搞他一搞.

坐公交车,拿出手机,在公众号看了几篇文章,顿时知道问题出在哪里.回来拎出电脑,修修改改.

虽然知道原因,但是语法不太熟悉,于是打开电脑搜了下,于是是这样的:

刚开始没注意,直接按照语法修改配置文件,重启服务.好了搞定.

然而回头仔细一看,嗯?? 博客主,你好骚啊,这个图片我必须down 下来,于是,出现如下:

尼玛,图片呢,图片呢,好吧,继续往下拉,出现如图所示:

老哥,你的girl来自哪里啊?????? 本来想玩一会休息,一看这样,算了,非给你找出来.
仔细看看,你瞧,这个东西比较特别,拉出来访问,看:

呵呵呵呵.........

但是图片变了啊,竟然是特么随机的,怎么办,继续看,看这里:

可以啊,藏的这么深,一激动,我去,又特么刷新了,原图不见了.不过,好歹知道怎么搞了,直接 copy image url 地址栏打开就好了.

注意:其实第一次访问获得图片并不是这里列出的,至于是哪一个,因为是随机的所以最后我也没有再次看到她,真失望. 于是搜索一下,等闲了用py蛇on搞他几万下.

其实怀疑,有人为了看图把他的博客刷了无数边,好心机,佩服.

**想访问的,点这个吧,https://api.ooopn.com/image/beauty/api.php?type=jump **

歌曲心血来潮

未实施,有空再搞

''' tk_image_view_url_io_resize.py
display an image from a URL using Tkinter, PIL and data_stream
also resize the web image to fit a certain size display widget
retaining its aspect ratio
Pil facilitates resizing and allows file formats other then gif
tested with Python27 and Python33 by vegaseat 18mar2013
'''
''' tk_image_view_url_io_resize.py
用Tkinter, PIL和data_stream从一个url地址加载图片，
能保持比例缩放适应显示大小， Pil便于缩放和读取各种图像格式，
在Python27和Python33上都测试过了 by vegaseat 18mar2013
