个性IP图[JAVA]

在网络上,可以看到一些论坛,一些网站上出现的个性的签名档。上面标注着你的IP,你的操作系统,你的浏览器以及你所在的位置。

当然网络上也有一些这类源码文件下载!

但大部分的都是php制作的,当然我也制作过php版的,然而今天就想到用Java也写一份玩玩。

ip.png

由于获取的User-Agent比较难解析,然后为了方便就调用了UserAgentUtils组件来解析:


 <dependency>
       <groupid>nl.bitwalker</groupid>
       <artifactid>UserAgentUtils</artifactid>
       <version>1.2.4</version>
  </dependency>


代码:

 /**
     * IP个性图片
     * @param request 要获取的request
     * @param srcImgPath 源图片路径
     * @param degree 旋转角度
     * @param color  字体颜色

使用方法:


BufferedImage img = GxIpImg(request,"F:/ip.png",0,new Color(255, 19, 19, 225));
response.setContentType("image/png");
ServletOutputStream out = response.getOutputStream();
ImageIO.write(img,"png",out);
