python调用hanlp的API，顺道对比java代码

hanlp里，可以对句法做分析。想省事，就直接调用hanlp的接口就行了。python代码如下：

import requests

def test_api():
    # 输入参数见: https://www.hanlp.com/HanLPfile/admin.html
    data = {
        'text': "张老师教我语文",
    }
    token = "你的token"  # token在hanlp官网里获取
    headers_dic = {
        "token": token,
    }

    # 使用 POST方式进行发送
    resp = requests.post("http://comdo.hanlp.com/hanlp/v1/dependency/dependency", data=data, headers=headers_dic)
    print("asr json:", resp.json())

if __name__ == '__main__':
    test_api()

按官方的参数发送的，非常简单。

但是再看官方给的java代码。70多行……，所以，再次说一下，我为啥不用java，而用python。因为我真的不想写那么多代码……
