Flutter:Instagram登录时未获取代码(Instagram登录工作不起作用)



我正在使用Flutter,我想在应用程序中使用Instagram登录。因此,我正在关注Instagram登录的本教程,

我将成功登录,但没有获取用户详细信息,它是打开重定向uri (https://www.google.com/),并且没有获取代码和访问令。<<<<<<<<<<<<<<<<<<<<<<<<<<<<

如果您不知道,请帮助我。

注意:我正在使用 flutter_webview_plugin 用于加载WebView 扑来。

这是打开 Instagram登录的WebView的代码 ->

我的日志 print(" code ============代码"); 不再打印

  Future<Token> getToken(String appId, String appSecret) async {
  Stream<String> onCode = await _server();
  print("_server ========== _server");
  String url =
      "https://api.instagram.com/oauth/authorize?client_id=$appId&redirect_uri=https://www.google.com/&response_type=code";
  final flutterWebviewPlugin = new FlutterWebviewPlugin();
  flutterWebviewPlugin.launch(url);
  final String code = await onCode.first;
  print("Code ========== Code");
  print("Code -> "+code);
  final http.Response response = await http.post(
      "https://api.instagram.com/oauth/access_token",
      body: {"client_id": appId, "redirect_uri": "https://www.google.com/", "client_secret": appSecret,
      "code": code, "grant_type": "authorization_code"});
  flutterWebviewPlugin.close();

  return new Token.fromMap(json.decode(response.body));
}
Future<Stream<String>> _server() async {
  final StreamController<String> onCode = new StreamController();
  HttpServer server =
  await HttpServer.bind(InternetAddress.LOOPBACK_IP_V4, 8585);
  server.listen((HttpRequest request) async {
    final String code = request.uri.queryParameters["code"];
    request.response
      ..statusCode = 200
      ..headers.set("Content-Type", ContentType.HTML.mimeType)
      ..write("<html><h1>You can now close this window</h1></html>");
    await request.response.close();
    await server.close(force: true);
    onCode.add(code);
    await onCode.close();
  });
  return onCode.stream;
}

iOS配置如果有人在寻找,请在以下代码添加到info.plist

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>localhost:8585</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
</dict>

最后,我发现答案实际上是正确的,

我的错误是更改重定向uri

所以我有更改重定向uri https://www.google.com/to http://localhost:8585 and Instagram login works。

Use http://localhost:8585 this Redirect URI for Instagram login
