使用 Flutter 应用程序登录 Salesforce CRM

如何解决使用 Flutter 应用程序登录 Salesforce CRM

您是否尝试过使用 Flutter 应用程序登录 Salesforce CRM？我正在使用 Oauth2 包 (https://pub.dev/packages/oauth2/example) 和资源所有者密码授予，但它有一些错误。这里是 _login() 方法：

    Future<void> _login() async {
    final authorizationEndpoint =
        Uri.parse('https://login.salesforce.com/services/oauth2/authorize');

    // The user should supply their own username and password.
    final username = 'tqtai@cts.com.vn';
    final password = 'anhtak@1234SYxVnDtJBIucYIZN7jhbdd7Fr';

    final identifier = '3MVG9YDQS5WtC11rWdcCAUYsljvKVu5IzgImWYMf_7GjORIztH1G_pO8GDxX4P3r6mSw3kZknaQ6W5C';
    final secret = 'B3E1C3349AAFEB99A98E29A9F7CB3D8F7B56A62B640651F0869F74A0A2B092';

    var client = await oauth2.resourceOwnerPasswordGrant(
        authorizationEndpoint,username,password,identifier: identifier,secret: secret);

    File('~/.myapp/credentials.json').writeAsstring(client.credentials.toJson());
    print('asdasdas');
}

这里是错误：

E/Flutter ( 6464): [ERROR:Flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: FormatException: Invalid OAuth response for "https://login.salesforce.com/services/oauth2/authorize": Content-Type was "null",expected "application/json".
