具有安全连接的 grpc dart 服务器和客户端示例 [英] grpc dart server and client exmple with secure connection
问题描述
我在 dart 中搜索了 grpc secure 服务器和客户端示例我找不到任何,可以找到创建 不安全连接 的示例,但这不是我想要的正在寻找.
I have searched for grpc secure server and client example in dart I couldn't find any, example of creating insecure connection can be found but this is not what I am looking for.
我已经设法安全地编译它,但在客户端和服务器之间连接时出现 grpc 错误
I have managed to compile it with secure but getting grpc error when connecting between client to server
捕获错误:gRPC 错误(代码:14,代码名称:UNAVAILABLE,消息:连接错误:HandshakeException:连接期间终止握手,详细信息:null,rawResponse:null)
Caught error: gRPC Error (code: 14, codeName: UNAVAILABLE, message: Error connecting: HandshakeException: Connection terminated during handshake, details: null, rawResponse: null)
我的服务器凭据实现:
final String myPath = 'password_file.pem';
final File f = File(myPath);
final Uint8List bytes = f.readAsBytesSync();
final server = Server(
[myPbServer()],
const <Interceptor>[],
CodecRegistry(codecs: const [GzipCodec(), IdentityCodec()]),
);
await server.serve(
port: 6053,
security: ServerTlsCredentials(certificate: bytes),
);
我的客户凭据实现:
final String myPath = 'password_file.pem';
final File f = File(myPath);
final Uint8List bytes = f.readAsBytesSync();
return channel = ClientChannel(
deviceIp,
port: 6053,
options: ChannelOptions(
credentials: ChannelCredentials.secure(
certificates: myPath,
),
),
);
有人可以回答工作安全的 grpc 服务器和客户端示例吗?.
Can someone answer with working secure grpc server and client example?.
推荐答案
服务器:
final server = Server([YourServerClass()]);
await server.serve(
port: portNumber,
security: ServerTlsCredentials(
certificate: File('crtFilePath/file.crt').readAsBytesSync(),
privateKey: File('keycrtFilePath/file.key').readAsBytesSync(),
),
);
客户:
import 'package:grpc/src/client/http2_connection.dart';
FixedConnectionClientChannel(
Http2ClientConnection(
serverAddress,
portNumber,
ChannelOptions(
credentials: ChannelCredentials.secure(
certificates: File('crtFilePath/file.crt').readAsBytesSync(),
authority: 'localhost',
),
),
),
);
class FixedConnectionClientChannel extends ClientChannelBase {
final Http2ClientConnection clientConnection;
List<ConnectionState> states = <ConnectionState>[];
FixedConnectionClientChannel(this.clientConnection) {
clientConnection.onStateChanged = (c) => states.add(c.state);
}
@override
ClientConnection createConnection() => clientConnection;
}
