昨天学了一天的Python（我的生产语言是java，也可以写一些shell脚本，算有一点点基础），今天有一个应用场景，就正好练手了。
这个功能之前再java里写过，比较粗糙，原来是在我本机跑的，今天老大要求要随时保持请求，就用Python改写了下，省的又把一个有跟多杂项的jar包传到服务器，省空间又不乱，而且好读。
先附上java代码：

(代码里的参数地址等我已做了隐藏，json格式可能不准确了，无所谓)
接下来上Python代码：

Python的写法确实很简洁高效（java代码里post的逻辑，我还是调用了自己的一个工具类，实际代码要更多），今后打算把Python作为优先脚本语言，处理简单问题很快。
