尝试从网站获取词典时出现TypeError

Question

我正在尝试使用以下代码获取电视指南信息。但是我得到了TypeError：字符串索引必须是整数

任何帮助都是非常有用的

import requests

url="https://www.digiturk.com.tr/_Services/TVguide/jProxy.aspx?cid=271&sd=13_4_2020_0_0"
html_content = requests.get(url).text
remove_copy="/*Copyright © 2009 Digital Platform İletişim Hizmetleri A.Ş. Tüm Hakları Saklıdır. Bu servisin izinsiz kullanımından doğacak tüm yasal yükümlülükleri izinsiz kullanan kişiler kabul etmiş sayılır.*/"
page_content=html_content.split(remove_copy)[-1]
null="null"

for ch in f["BChannels"]:
    for pr in ch["CPrograms"]:
        print(pr["PName"], pr["POName"], pr["BID"], pr["PDuration"])

Answer 1

尝试：

import requests

url="https://www.digiturk.com.tr/_Services/TVguide/jProxy.aspx?cid=271&sd=13_4_2020_0_0"
html_content = requests.get(url).text
remove_copy="/*Copyright © 2009 Digital Platform İletişim Hizmetleri A.Ş. Tüm Hakları Saklıdır. Bu servisin izinsiz kullanımından doğacak tüm yasal yükümlülükleri izinsiz kullanan kişiler kabul etmiş sayılır.*/"
page_content=html_content.split(remove_copy)[-1]
null="null"
f = eval(page_content)
for ch in f["BChannels"]:
    for pr in ch["CPrograms"]:
        print(pr["PName"], pr["POName"], pr["BID"], pr["PDuration"])

eval()将字符串转换为字典，以便可以遍历它。
也可以使用json库代替eval（）。（需要使用import json导入json） 更改：

f = eval(page_content)

致：

f = json.loads(page_content)

输出：

Answer 2

page_content=html_content.split(remove_copy)[-1]

page_content是一个字符串。您必须解析它才能将其用作dict：

import json
...
page_content = json.loads(html_content.split(remove_copy)[-1])
...
for ch in page_content["BChannels"]:
    for pr in ch["CPrograms"]:
        print(pr["PName"], pr["POName"], pr["BID"], pr["PDuration"])
