团油接口分析，获取附近油站油价信息

从网络请求中可以看到接口请求中有对传递的参数签名，

通过反编译团油apk，可以从源码中找到接口签名方法和参数。

反编译安卓需要用到的三件套 apktool、dex2jar2.0、jd-gui ， 网上下载好，按说明操作即可

# app_key
app4.0.2_android
# app_secret
2674614042c372d9d9179d9769781a04

# 签名方法
app_secret + 参数按字母排序后连接名和值 + app_secret , MD5-32位小

> sign = md5(2674614042c372d9d9179d9769781a04app_keyapp4.0.2_androidapp_version6.3.6shumeiIDtimestamp1615942421019token6d681475ecc94320a07c9183faa038052674614042c372d9d9179d9769781a04)

除sign外所有请求参数都要参与签名，关键参数说明：
timestamp 当前时间戳13位
token 登录token，一段时间可能失效，需要重新获取
userLatStr  位置维度，高德坐标系
userLngStr 位置经度
