记一次使用阿里云图像搜索功能

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。

源码更改地方

encoded_pic_name = str(base64.b64encode(bytes(pic_name, 'utf-8')), encoding='utf-8') encoded_pic_content = base64.b64encode(pic_content).decode('utf8')
