或许你没注意到，首页的菜单上面增加了美女欣赏，观赏地址：主要使用了php来读取JSon，然后判断，如果有图片，那么进行输出，如果没有图片，就直接返回，后面还使用了timthumb.php来截取图片。要使用本功能，你先要在进行注册，获取美女图片的API。
第一步：获取API内容，并且创建文件是否存在的判断函数
第二步：判断文件是否存在，如果文件存在那么显示

-------====Website Screenshots configuration - BETA====-------
If you just want image thumbnails and don't want website screenshots,you can safely leave this as is. If you would like to get website screenshots set up,you will need root access to your own server. Enable ALLOW_ALL_EXTERNAL_SITES so you can fetch any external web page. This is more secure now that we're using a non-web folder for cache. Enable BLOCK_EXTERNAL_LEECHERS so that your site doesn't generate thumbnails for the whole Internet. Instructions to get website screenshots enabled on Ubuntu Linux: 1. Install Xvfb with the following command: sudo apt-get install subversion libqt4-webkit libqt4-dev g++ xvfb 2. Go to a directory where you can download some code 3. Check-out the latest version of CutyCapt with the following command: svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt 4. Compile CutyCapt by doing: cd cutycapt/CutyCapt 5. qmake 6. make 7. cp CutyCapt /usr/local/bin/ 8. Test it by running: xvfb-run --server-args="-screen 0,1024x768x24" CutyCapt --url="http://markmaunder.com/" --out=test.png 9. If you get a file called test.png with something in it,it probably worked. Now test the script by accessing it as follows: 10. http://yoursite.com/path/to/timthumb.php?src=http://markmaunder.com/&webshot=1 Notes on performance: The first time a webshot loads,it will take a few seconds. From then on it uses the regular timthumb caching mechanism with the configurable options above and loading will be very fast. --ADVANCED USERS ONLY-- If you'd like a slight speedup (about 25%) and you know Linux,you can run the following command which will keep Xvfb running in the background. nohup Xvfb :100 -ac -nolisten tcp -screen 0,1024x768x24 > /dev/n<a href="https://m.jb51.cc/tag/ul/" target="_blank" >ul</a>l 2>&1 & Then set WEBSHOT_XVFB_RUNNING = true below. This will save your server having to fire off a new Xvfb server and shut it down every time a new shot is generated. You will need to take responsibi<a href="https://m.jb51.cc/tag/li/" target="_blank" >li</a>ty for kee<a href="https://m.jb51.cc/tag/Ping/" target="_blank" >Ping</a> Xvfb running in case it crashes. (It seems pretty s<a href="https://m.jb51.cc/tag/table/" target="_blank" >table</a>) You will also need to take responsibi<a href="https://m.jb51.cc/tag/li/" target="_blank" >li</a>ty for server s<a href="https://www.jb51.cc/tag/ecurity/" target="_blank" >ecurity</a> if you're running Xvfb as root.
