代码：

import requests
from bs4 import BeautifulSoup

url="https://covid19.saglik.gov.tr/"
R=requests.get(url)             
print(R.text)

问题：您好朋友，我必须从上述网站收到以下特定值。这些值每天都在变化。程序运行时，应该可以从网站打印出指定的键。例如： print(data["tarih"]) , print(data["gunluk_test"]) , print( html 脚本中的 data["gunluk_vaka"] 等。我该怎么做？

代码的输出结果：

var sondurumjson = [{"tarih":"13.05.2021","gunluk_test":"201.295","gunluk_vaka":"11.534","gunluk_hasta":"1.217","gunluk_vefat":"238", "gunluk_iyilesen":"55.472","toplam_test":"50.259.943","toplam_hasta":"5.083.996","toplam_vefat":"44.059","toplam_iyilesen":"4.856.763","toplam_yogun_bakim": "","toplam_entube":"","hastalarda_zaturre_oran":"4,0","agir_hasta_sayisi":"2.765","yatak_doluluk_orani":"43,7","eriskin_yogun_bakim_doluluk_orani":"65,0","ventilator_doluluk_orani ":"32,4","ortalama_filyasyon_suresi":"","ortalama_temasli_tespit_suresi":"8","filyasyon_orani":"99,9"}];//]]>

看起来 dict 已经被 python 识别了，所以 json.loads 失败是你粘贴了 api 的输出还是打印了你正在处理的 dict？无论如何，如果这是您的 api 的结果，您可以这样做来访问字典中的所有内容：

sondurumjson = [{"tarih":"13.05.2021","gunluk_test":"201.295","gunluk_vaka":"11.534","gunluk_hasta":"1.217","gunluk_vefat":"238","gunluk_iyilesen":"55.472","toplam_test":"50.259.943","toplam_hasta":"5.083.996","toplam_vefat":"44.059","toplam_iyilesen":"4.856.763","toplam_yogun_bakim":"","toplam_entube":"","hastalarda_zaturre_oran":"4,0","agir_hasta_sayisi":"2.765","yatak_doluluk_orani":"43,7","eriskin_yogun_bakim_doluluk_orani":"65,0","ventilator_doluluk_orani":"32,4","ortalama_filyasyon_suresi":"","ortalama_temasli_tespit_suresi":"8","filyasyon_orani":"99,9"}]
new_object = sondurumjson[0]

print(new_object['tarih'])

我认为你应该使用 R.json() 而不是 R.text

【解决方案3】：

导入请求

从 bs4 导入 BeautifulSoup

导入 json

url="https://covid19.saglik.gov.tr/"

R=requests.get(url)

soup=BeautifulSoup(R.content,"html.parser" )

script=soup.find_all("script")[18]

s=str(script).split('\nvar sondurumjson = ')

#print(s[1])

a=str(s[1])

b=a.split("\r")

#print(b[0])

c=b[0].partition(';')

数据=c[0] #打印（数据）

数据 = json.loads(数据)

print("Tarih:", data[0]['tarih'])

print("Günlük 测试：", data[0]['gunluk_test'])

print("Günlük Vaka:", data[0]['gunluk_vaka'])
