LocalServer与颤振应用的连接

Question

我有一个问题，有关颤振应用程序开发。问题是，“是否有可能在没有防火墙的情况下实现OAuth2？”

基本上，我希望将我的Android应用程序与自己的本地服务器链接起来，以验证用户的身份。每个人都先在那里注册，然后再向火场申请。如果有任何解决办法，请与我分享。

您可以使用oauth2客户端包https://pub.dev/packages/oauth2

Github https://github.com/dart-lang/oauth2

客户端凭据授予代码段

// This URL is an endpoint that's provided by the authorization server. It's
// usually included in the server's documentation of its OAuth2 API.
final authorizationEndpoint =
    Uri.parse("http://example.com/oauth2/authorization");

// The OAuth2 specification expects a client's identifier and secret
// to be sent when using the client credentials grant.
//
// Because the client credentials grant is not inherently associated with a user,
// it is up to the server in question whether the returned token allows limited
// API access.
//
// Either way, you must provide both a client identifier and a client secret:
final identifier = "my client identifier";
final secret = "my client secret";

// Calling the top-level `clientCredentialsGrant` function will return a
// [Client] instead.
var client = await oauth2.clientCredentialsGrant(
    authorizationEndpoint, identifier, secret);

// With an authenticated client, you can make requests, and the `Bearer` token
// returned by the server during the client credentials grant will be attached
// to any request you make.
var response = await client.read("https://example.com/api/some_resource.json");

// You can save the client's credentials, which consists of an access token, and
// potentially a refresh token and expiry date, to a file. This way, subsequent runs
// do not need to reauthenticate, and you can avoid saving the client identifier and
// secret.
await credentialsFile.writeAsString(client.credentials.toJson());
