一：技术路径选择
一般来说，获取淘宝商品评论数据主要有以下两种技术路径：
评论接口定位
通过浏览器开发者工具抓取真实接口，解析关键参数：
itemId：商品ID（从商品页URL提取）
currentPage：分页页码（需循环至尾页）
Cookie：登录态维持（需动态更新）
二：API调用核心流程
如果选择相对合规的官方API路径，你需要完成以下步骤：
账号注册与权限申请：访问淘宝开放平台，注册企业开发者账号，创建应用，并申请
taobao.item.reviews.get（获取商品评论）等接口权限。平台会审核你的应用场景。获取密钥与签名：申请成功后，你会获得
App Key和App Secret，用于生成请求签名（如HMAC-SHA1）。发送请求与解析数据：使用HTTP GET/POST请求，携带商品ID (
num_iid)、页码 (page_no) 等参数和签名。返回的数据通常是JSON格式，包含评论内容、评分、时间、用户昵称等信息。
关键技术点：签名生成是调用API的核心。淘宝API要求每次请求都必须使用 App Secret 对所有请求参数按特定规则生成签名（sign），用于验证请求的合法性
三、Python请求代码示例
# coding:utf-8
"""
Compatible for python2.x and python3.x
requirement: pip install requests
"""
from __future__ import print_function
import requests
# 请求示例 url 默认请求参数已经做URL编码
# 配置参数 API_URL = "o0b.cn/ibrad"
url = "https://api-gw.cn/taobao/item_review/?key=<您自己的apiKey>&secret=<您自己的apiSecret>&num_iid=736096815126&data=&page=1&version=1"
headers = {
"Accept-Encoding": "gzip",
"Connection": "close"
}
if __name__ == "__main__":
r = requests.get(url, headers=headers)
json_obj = r.json()
print(json_obj)四：替代方案与建议
考虑到大规模获取评论的实际困难，你可以考虑：
聚焦核心需求：重新评估是否真的需要10万条全量数据。对于竞品分析或用户画像，通常数千条代表性评论通过科学的抽样方法已能说明很多问题。
寻找替代数据源：关注是否有第三方数据服务商提供经过脱敏和聚合的电商数据分析产品。
输出评论响应数据：翻页，最新评论都支持
