字符串在Python中必须是整数

Question

我试图从api获得url值，但有一个问题说TypeError:字符串索引必须是整数

这是我从api得到的数组:

[
{
"created_utc": 1643524062,
"title": "title",
"url": "https://i.redd.it/tmd5shz9rre81.gif",
},
{
"created_utc": 1643530657,
"title": "title",
"url": "https://i.redd.it/qqjykysxase81.gif",
}
]

下面是我用来获取url的代码:

url = "https://reddit-meme.p.rapidapi.com/memes/trending"
headers = {
"X-RapidAPI-Key": "83df5aba87msh4580fa40781b33cp12157bjsnb4b412cb57da",
"X-RapidAPI-Host": "reddit-meme.p.rapidapi.com"
}
response = requests.request("GET", url, headers=headers)
print(response.text[0]["url"])

我做错了什么?

Answer 1

response.text是一个字符串，您必须首先解析它，使用json库，如下所示:

import requests
import json

url = "https://reddit-meme.p.rapidapi.com/memes/trending"
headers = {
"X-RapidAPI-Key": "83df5aba87msh4580fa40781b33cp12157bjsnb4b412cb57da",
"X-RapidAPI-Host": "reddit-meme.p.rapidapi.com"
}
response = requests.request("GET", url, headers=headers)
data = json.loads(response.text)
print(data[0]["url"])
