记一次使用阿里云图像搜索功能
阿里云提供的图像搜索业务：
业务介绍地址：
https://ai.aliyun.com/imagesearch?spm=5176.10695662.1280361.130.11a61e6d5n1K8L
提供两种服务：
- 商品图像搜索；
- 通用图像搜索；
开发文档
文档地址：
https://help.aliyun.com/document_detail/66616.html
目前在该页支持的sdk有：
- Java
- Nodejs
- PHP
从文档来看使用起来十分复杂，想用python实现的话，借鉴这份资料真是费了很大力气，一直没有跑通，提示构建的签名与它计算的签名不匹配。
后面找寻python sdk。
python sdk使用指南
https://help.aliyun.com/document_detail/67117.html
按照这个介绍，自己安装了核心库，并歪打正着的通过pip安装找到了该服务的隐藏python sdk！
pip install aliyun-python-sdk-imagesearch然后去aliyun的gihub页面找相关的包介绍：
https://github.com/aliyun/aliyun-openapi-python-sdk/tree/master/aliyun-python-sdk-imagesearch
介绍不是很详细，也花了一天的时间试错。
最终调通，该sdk对python3目前也不支持，卡在字符串编码这块，后续应该会解决这个问题。
使用该sdk，更改下包的源码（base64编码的字符串问题），在python3下跑通整个过程，上传图片，删除图片以及搜索图片。
