s=input('请输入中文:')

data={'kw':s}

res=requests.post(url,headers=headers,data=data)
code=res.status_code
if  code==200:
    print('请求成功')
    data=res.json()        #返回文本
    if  data['errno']==0:
        print('响应成功')
        print(data['data'][0]['k'])
        v=data['data'][0]['v']
        a=v.split(';')[-2]
        print(s+':'+a)
