Get URL of a http get request in flutter app

Question

I am trying to get the URL of the following get request;

String url = ['url_here'];
Future<Post> fetchPost() async {
final response = await http.get(url);

if (response.statusCode == 200) {
return Post.fromJson(json.decode(response.body));
} else {
throw Exception('Failed to load post');
}
}

I get a statuscode of 200.

Any ideas?

To clarify, When you enter the url in a browser it brings me to a page with a url that has a code in it. I am trying to extract that code.

can you add some of your logs

Are you using HTTP from dart:io or from package:http?

followRedirects is true by default and I haven't found a way to get the URL it redirects to this way.

Setting followRedirects = false returns the new address in the location header.

  final url = 'http://wikipedia.net';
  final client = http.Client();
  final request = new http.Request('GET', Uri.parse(url))
    ..followRedirects = false;
  final response = await client.send(request);

  print(response.headers['location']);
  print(response.statusCode);

If you want to fetch the content of the redirect address, you can send a new request with the URL from location or just with the default (followRedirects = true)

is redirect is false

Günter Zöchbauer Over a year ago

What is the response code? Is the location header set?

Is it a public URL that I can test myself with?

Darran Mullen Over a year ago

response.statusCode = 200, and no the location header is not set

its not public. i'm trying to connect fitbit to my app. on their OAuth 2.0 tutorial page they build the url with clientsecret etc. they say: Copy and paste the code that you can find in the redirect URL after the user has clicked the "allow" button. Example: localhost:8888/…, the code you need to paste from that example is 7b64c4b088b9c841d15bcac15d4aa7433d35af3e. Don't include the “#_=_”.
