Are you sure you are requesting from the correct URL?您确定您从正确的 URL 请求？

looks like two URLs to me.对我来说看起来像两个 URL。 If you enter it "raw" as you did you get a html site saying: Missing required request header. Must specify one of: origin,x-requested-with如果你输入它“原始”，你会得到一个 html 网站说： Missing required request header. Must specify one of: origin,x-requested-with Missing required request header. Must specify one of: origin,x-requested-with . Missing required request header. Must specify one of: origin,x-requested-with 。
The Json data is at Json 数据位于
https://newsapi.org/v2/top-headlines?q=india&apiKey=f4176dc9b5194205b4ea64370c715b9b
Since it is trying to parse html it reads the < of the html tags and throws an error there.由于它试图解析 html 它读取 html 标签的<并在那里引发错误。 Try changing the URL and look if that fixes it.尝试更改 URL 并查看是否可以解决问题。
The raw data at the URL you provide is您提供的 URL 的原始数据是
<html><head><link rel="stylesheet" href="resource://content-accessible/plaintext.css"></head><body><pre>Missing required request header. Must specify one of: origin,x-requested-with</pre></body></html>
which understandably isn't a valid json format.可以理解，这不是有效的 json 格式。
