python-3.x - 使用app-store-scraper检索AppStore应用程序的评论时出错？

Question

这是我尝试过的，但没有成功:
首先pip3 install app-store-scraper，然后:

from app_store_scraper import AppStore
from pprint import pprint

appstore_app = AppStore(country="us", app_name="yazio-fasting-food-tracker", app_id=946099227)
appstore_app.review()

pprint(appstore_app.reviews)
pprint(appstore_app.reviews_count)

错误:

请告知如何处理此错误，或者可能存在另一种解析AppStore评论的方法。

Answer 1

我已经用这个API包装器玩了一点，看来您返回的结果是基于IP的，或者包装器有些奇怪。
无论如何，这是我获得533条评论的代码。整个转储位于pastebin上。

import json

from app_store_scraper import AppStore
from pprint import pprint

appstore_app = AppStore(country="us", app_name="yazio-fasting-food-tracker", app_id=946099227)
appstore_app.review()

reviews = appstore_app.reviews
pprint(appstore_app.reviews_count)

for review in reviews:
    review['date'] = review['date'].isoformat()


with open("data_dump.json", "w") as dd:
    json.dump(reviews, dd, indent=4, sort_keys=True)

输出:
