轻松绕过 Graphql 接口爬取有米有数的商品数据
有米有数数据的 API 接口，使用的是一种 API 查询语言 graphql。所有的 API 只有一个入口，具体的操作隐藏在请求数据体里面传输。
模拟登录，获取 sessionId
调用登录接口，进行模拟登录。
cookies = {}
headers = {}
json_data = {
'operationName': 'userLogin',
'query': 'mutation userLogin(\n $account: String!\n $password: String!\n $appId: String\n $goto: String\n $riskData: JSON\n $keep_login: Int\n $confirm_agreement: Int\n $params: JSON\n ) {\n login(\n account: $account\n password: $password\n appId: $appId\n goto: $goto\n riskData: $riskData\n keep_login: $keep_login\n confirm_agreement: $confirm_agreement\n params: $params\n ) {\n \n user {\n user_id\n mobile\n email\n wx_union_id\n mobile_verified\n email_verified\n register_at\n extendInfo {\n industry\n duty\n company\n contact_name\n wx_nickname\n avatar\n }\n }\n\n goto\n }\n }',
'variables': {
'keep_login': 1,
'account': 'xxx',
'password': 'xxx',
'params': {
'app_id': '',
'goto': 'https://finance.youcloud.com/account/password',
},
'appId': '',
'goto': 'https://finance.youcloud.com/account/password',
},
}
response = requests.post('https://api-auth.youcloud.com/graphql', cookies=cookies, headers=headers, json=json_data)
print(response.cookies.items())
从 Cookie 数据中，获取到的 sessionId。
[('sessionId', 'eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJqdGkiOiI5SDVNMFI3TEFGMVdVNjQ0NWYwYTY4YzZhZiIsImV4cCI6MTY4NDg5NzE5MCwic3ViIjoiNzY4MDY4In0.JeVFFbkIQxe60SwBGqBj93q13OP5ZtA8vC__9ymQwf_wOxfIxooiD4n5TMRPWjRl8ITnHlAEEDxttCxCZ4z8ww')]
爬取商品列表数据
将上面获取到的 sessionId，应用到其他接口；这里调用商品列表接口。
cookies = {
'sessionId': 'eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJqdGkiOiJZMzBEMzM1OU4yUjJBNjQ0M2EwNmVjYmQxYyIsImV4cCI6MTY4NDc0NTU4Miwic3ViIjoiNzY4MDY4In0.li3sxOomDNH7fiA06uMDmLn4cjAZRPWHwx9liHD3yT4iitbAv4EkIFohoHr1o3_CmrZzTPtuB-hq3EJsc0njfQ',
}
headers = {}
json_data = {
'operationName': 'productRealTimeList',
'query': '\n query productRealTimeList (\n $site_id: String\n $category: String\n $promotionType: String\n $shopType: String\n $hasBrand: String\n $min_qs_incr_24h: String\n $max_qs_incr_24h: String\n $min_qs_incr_12h: String\n $max_qs_incr_12h: String\n $min_qs_incr_6h: String\n $max_qs_incr_6h: String\n $min_qs_total: String\n $max_qs_total: String\n $min_qs_incr_day: String\n $max_qs_incr_day: String\n $min_qs_incr_amount_day: String\n $max_qs_incr_amount_day: String\n $page: Int!\n $sort: ProductListSort!\n $min_measure: String\n $max_measure: String\n $isExport: Boolean!\n ) {\n productRealTimeList (\n site_id: $site_id\n category: $category\n promotionType: $promotionType\n shopType: $shopType\n hasBrand: $hasBrand\n min_qs_incr_24h: $min_qs_incr_24h\n max_qs_incr_24h: $max_qs_incr_24h\n min_qs_incr_12h: $min_qs_incr_12h\n max_qs_incr_12h: $max_qs_incr_12h\n min_qs_incr_6h: $min_qs_incr_6h\n max_qs_incr_6h: $max_qs_incr_6h\n min_qs_total: $min_qs_total\n max_qs_total: $max_qs_total\n min_qs_incr_day: $min_qs_incr_day\n max_qs_incr_day: $max_qs_incr_day\n min_qs_incr_amount_day: $min_qs_incr_amount_day\n max_qs_incr_amount_day: $max_qs_incr_amount_day\n sort: $sort\n page: $page\n min_measure: $min_measure\n max_measure: $max_measure\n isExport: $isExport\n ) {\n data {\n product {\n \n id @skip(if: $isExport)\n category @skip(if: $isExport) {\n \n id\n name\n\n }\n header_image @skip(if: $isExport) {\n \n path\n\n }\n url\n title\n price\n site {\n \n id\n name\n icon\n\n }\n shop {\n \n id\n name\n qualification_url\n dsr\n\n has_brand\n talent {\n \n uid\n avatar_url\n nickname\n\n track_url\n }\n }\n seller_company {\n \n id\n screenName\n\n }\n first_monitor_time\n modify_time\n isNew @skip(if: $isExport)\n\n }\n promotionType {\n \n id\n name\n shortName\n\n }\n measureValue\n qs_incr_24h\n qs_incr_24h_ratio\n qs_incr_12h\n qs_incr_6h\n qs_incr_3h\n qs_incr_1h\n qs_amount_incr\n qs_total\n }\n total\n limit\n }\n }\n ',
'variables': {
'site_id': '10501',
'sort': 'qs_incr_24h',
'page': 1,
'isExport': False,
},
}
response = requests.post('https://api.youshu.youcloud.com/graphql', cookies=cookies, headers=headers, json=json_data)
print(response.json())

小结
- 有米有数数据接口使用的是 graphql 查询语言。
- 调用登录接口，获取到 sessionId。
- 使用 sessionId 便可以爬取到商品数据。
