http.get : SocketException

[taojigu]

The Code is:

void _requestArticleIDList () async {
var url = 'https://hacker-news.firebaseio.com/v0/topstories.json?print=pretty';
var response = await http.get(url);
if (response.statusCode != 200 ) {
return;
}
}

The Result I Get

E/flutter ( 5470): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: SocketException: OS Error: No route to host, errno = 113, address = hacker-news.firebaseio.com, port = 46698

It's giving you an OS error - "No route to host". Looks like a problem with the environment - what do you think needs to happen in this package?

[taojigu]

The exception only is thrown when access 'https://hacker-news.firebaseio.com/v0/topstories.json?print=pretty' . When accessing other urls, it works fine.

[natebosch]

Can you access that url otherwise on your device?

Does it work if you use https://api.dartlang.org/stable/2.2.0/dart-io/HttpClient-class.html directly?

my fault, found reason: hacker-news.filrebase.io.com is blocked by china government.
