二、快速上手：Python 示例代码
1️⃣ 淘宝评论 API（官方）
python
`import requests
import hashlib
import time
APP_KEY = "your_app_key"
APP_SECRET = "your_app_secret"
SESSION = "your_session"
def get_taobao_reviews(item_id, page=1, page_size=20):
url = "https://gw.api.taobao.com/router/rest"
params = {
"method": "taobao.item.review.get",
"app_key": APP_KEY,
"session": SESSION,
"timestamp": time.strftime("%Y-%m-%d %H:%M:%S"),
"format": "json",
"v": "2.0",
"sign_method": "md5",
"item_id": item_id,
"page_no": page,
"page_size": page_size,
"rate_type": "getTime", # 按时间排序
"fields": "tid,nick,created,content,rate,sku_id,user_level,auction_sku",
}
# 签名逻辑（省略，需按淘宝规范生成 sign）
response = requests.get(url, params=params)
return response.json()
# 调用
reviews = get_taobao_reviews("652345678901", page=1, page_size=100)
print(f"获取到 {len(reviews)} 条评论")
`2️⃣ 京东评论 API（官方）
python
`import requests
import hashlib
import time
APP_KEY = "your_app_key"
APP_SECRET = "your_app_secret"
ACCESS_TOKEN = "your_token"
def get_jd_reviews(sku_id, page=0, page_size=10):
url = "https://api.jd.com/routerjson"
params = {
"method": "jd.union.open.goods.review.list.get",
"app_key": APP_KEY,
"access_token": ACCESS_TOKEN,
"timestamp": time.strftime("%Y-%m-%d %H:%M:%S"),
"format": "json",
"v": "1.0",
"sign_method": "md5",
"skuId": str(sku_id),
"pageIndex": page,
"pageSize": page_size,
"sortType": 5, # 5=时间倒序
}
# 签名...
resp = requests.get(url, params=params)
return resp.json()
reviews = get_jd_reviews(100012345678, page=0, page_size=50)
`3️⃣ 第三方聚合 API（最简单，推荐）
python
`import requests
# 示例：使用 "八卦数据" 聚合API
API_KEY = "your_api_key"
def get_reviews_simple(platform, item_id, page=1):
url = f"https://api.baguapi.com/{platform}/reviews"
headers = {"Authorization": f"Bearer {API_KEY}"}
params = {
"item_id": item_id,
"page": page,
"page_size": 100,
"sort": "time_desc",
"include": "content,nick,rate,images,sku,time",
}
resp = requests.get(url, headers=headers, params=params)
return resp.json()
# 一键获取淘宝评论
data = get_reviews_simple("taobao", "652345678901")
print(f"共 {data['total']} 条评论，本页 {len(data['list'])} 条")
for r in data['list'][:3]:
print(f"{r['nick']} | {r['rate']}⭐ | {r['content'][:30]}...")
`三、评论数据结构（标准化）
json
`{
"item_id": "652345678901",
"reviews": [
{
"user_id": "u_123456",
"nick": "数码发烧友小王",
"avatar": "https://...",
"rate": 5,
"content": "屏幕素质很好，色准 ΔE<2，做设计完全够用，就是风扇声音有点大...",
"sku": "i9-14900K + RTX4070",
"images": ["img1.jpg", "img2.jpg"],
"created_at": "2024-03-15 14:23:00",
"user_level": "VIP3",
"purchase_count": 12,
"tags": ["屏幕好", "风扇吵", "性价比高"]
}
]
}
