一、接口概述
拍立淘是义乌购平台提供的以图搜货服务,通过HTTP RESTful API实现。当前版本为v3.2,支持JPG/PNG格式图片(≤5MB),返回相似商品列表及供应链信息。

二、接入准备
makefile
# 开发者注册示例(伪代码)
import requests
auth_url = "https://open.yiwugo.com/oauth2/token"
params = {
"client_id": "your_app_key",
"client_secret": "your_app_secret",
"grant_type": "client_credentials"
}
response = requests.post(auth_url, data=params)
access_token = response.json()["access_token"]
三、核心接口调用
-
图片上传接口
def image_search(image_path, token): url = "api.yiwugo.com/v3/image/se..." headers = {"Authorization": f"Bearer {token}"}
pythonwith open(image_path, 'rb') as f: files = {'image': (image_path.split('/')[-1], f, 'image/jpeg')} response = requests.post(url, files=files, headers=headers) if response.status_code == 200: return response.json()["data"]["items"] else: raise Exception(f"API Error: {response.text}")
调用示例
results = image_search("product.jpg", access_token)
-
响应数据结构
{ "code": 200, "data": { "items": [ { "product_id": "P123456", "similarity": 0.92, "price_range": [2.5, 3.8], "main_image": "img.yiwugo.com/...", "supplier_info": { "company_id": "C7890", "gold_supplier": true } } ] } }
四、最佳实践
python
图片预处理建议:
分辨率建议800x800像素
使用白色背景商品图
避免水印和拼接图
错误处理:
try:
results = image_search("demo.jpg", token)
except Exception as e:
print(f"搜索失败:{str(e)}")
# 建议重试机制:间隔2秒重试3次
五、QPS限制
基础版:1次/秒 企业版:10次/秒(需签约)
