网页抓取 Roblox

Question

我的问题是我正在使用 selenium 抓取我在 roblox 上的销售情况，因为每次都请求 returns 错误值，所以我让 selenium 将我的 json 响应写入文本文件。

现在我只想从中获取销售额，我该怎么做？

这是我的 python 函数，还有我的 response.txt

def submitData(self):
        self.title.setText("Roblox Sales Checker")
        try:
            ID = self.ID_INPUT.text()
            url = f'https://api.roblox.com/Marketplace/ProductInfo?assetId={ID}'

            driver.get(url)
            driver.add_cookie("My Auth Cookie,but not for you :)")
            driver.refresh()

            search = driver.find_element_by_css_selector("body > pre").text

            f = open('apiResponse.txt', 'w')
            f.write(search)
            f.close()

            f = open('apiResponse.txt', 'r+')
            apiResponseText = f.readlines()

            print(apiResponseText)

{"TargetId":6970745869,"ProductType":"User Product","AssetId":6970745869,"ProductId":1183920723,"Name":"beautifulSky","Description":"","AssetTypeId":10,"Creator":{"Id":2657343484,"Name":"Bestgamedev1209","CreatorType":"User","CreatorTargetId":2657343484},"IconImageAssetId":0,"Created":"2021-06-18T15:12:36.253Z","Updated":"2021-06-18T15:12:36.297Z","PriceInRobux":null,"PriceInTickets":null,"Sales":20624,"IsNew":false,"IsForSale":false,"IsPublicDomain":true,"IsLimited":false,"IsLimitedUnique":false,"Remaining":null,"MinimumMembershipLevel":0,"ContentRatingTypeId":0}

Answer 1

如果您 import json，销售额将给出：

json.loads(apiResponseText)["Sales"]

这是一个小例子：

import json
apiResponseText='{"TargetId":6970745869,"ProductType":"User Product","AssetId":6970745869,"ProductId":1183920723,"Name":"beautifulSky","Description":"","AssetTypeId":10,"Creator":{"Id":2657343484,"Name":"Bestgamedev1209","CreatorType":"User","CreatorTargetId":2657343484},"IconImageAssetId":0,"Created":"2021-06-18T15:12:36.253Z","Updated":"2021-06-18T15:12:36.297Z","PriceInRobux":null,"PriceInTickets":null,"Sales":20624,"IsNew":false,"IsForSale":false,"IsPublicDomain":true,"IsLimited":false,"IsLimitedUnique":false,"Remaining":null,"MinimumMembershipLevel":0,"ContentRatingTypeId":0}'
y=json.loads(apiResponseText)["Sales"]
print(y)

输出为：
