淘宝拍立淘按图搜索API接口示例

淘宝的拍立淘(图片搜索)功能通常是通过淘宝开放平台提供的API实现的。以下是一个模拟的JSON数据示例和接口调用参考：

	`import requests`
	`import base64`

	`# 示例图片路径`
	`image_path = "example.jpg"`

	`# 读取图片并编码为base64`
	`with open(image_path, "rb") as image_file:`
	`encoded_image = base64.b64encode(image_file.read()).decode('utf-8')`

	`# API请求参数`
	`url = "https://eco.taobao.com/router/rest" # 淘宝开放平台API地址(示例)`
	`params = {`
	`"method": "taobao.tbk.item.get", # 实际拍立淘API方法名可能不同`
	`"app_key": "your_app_key",`
	`"timestamp": "2023-01-01 12:00:00",`
	`"format": "json",`
	`"v": "2.0",`
	`"sign_method": "md5",`
	`"sign": "your_sign_here", # 需要根据淘宝开放平台规则生成`
	`"image": encoded_image, # 图片base64编码`
	`"num": 10, # 返回结果数量`
	`"similarity_threshold": 0.8 # 相似度阈值(0-1)`
	`}`

	`# 发送请求`
	`response = requests.get(url, params=params)`
	`result = response.json()`
