VSOMEIP - 2 台设备之间的通信 (TCP/UDP) 不工作

Question

正在学习 VSOMEIP 教程 Vsomeip in 10 minutes everything works up to the point of Communication between 2 devices。

当前设置：

Ubuntu 16.04（两台机器 - 服务器和客户端）
两台机器通过以太网连接

使用的文件：

server.cpp
client.cpp
client_config.json
server_config.json

服务器输出

客户端输出

[warning] Releasing client identifier 0003. Its corresponding application went offline while no routing manager was running.
[info] Application/Client 0003 is deregistering.

使用的所有代码与 Request/Response in the vsomeip tutorial. The config files are the same as the config file specified in the communication between 2 devices 部分中使用的代码相同 IP 地址已更改以匹配我的机器地址。

非常感谢任何帮助，谢谢。

我找到了解决办法！！

如果您导航到 vsomeip 或 vsomeip-master 目录中的 /build/examples 文件夹，您会发现可执行文件（响应样本、订阅样本等）。如果您运行他们使用与 vsomeip 中使用的配置文件相同的配置文件，在 10 分钟后 （更改单播地址等），它应该可以完美运行。 这是我使用的配置文件。

{
    "unicast" : "192.168.43.6",
    "logging" :
    {
        "level" : "debug",
        "console" : "true",
        "file" : { "enable" : "false", "path" : "/tmp/vsomeip.log" },
        "dlt" : "false"
    },
    "applications" :
    [
        {
            "name" : "World",
            "id" : "0x1212"
        }
    ],
    "services" :
    [
        {
            "service" : "0x1234",
            "instance" : "0x5678",
            "unreliable" : "30509"
        }
    ],
    "routing" : "World",
    "service-discovery" :
    {
        "enable" : "true",
        "multicast" : "224.224.224.245",
        "port" : "30490",
        "protocol" : "udp",
        "initial_delay_min" : "10",
        "initial_delay_max" : "100",
        "repetitions_base_delay" : "200",
        "repetitions_max" : "3",
        "ttl" : "3",
        "cyclic_offer_delay" : "2000",
        "request_response_delay" : "1500"
    }
}

我使用 shell 脚本来做到这一点。

#!/bin/bash
route add -host 224.224.224.245 dev <interface>
export VSOMEIP_CONFIGURATION=<config_file>
export VSOMEIP_APPLICATION_NAME=<application_name>
./<executable>

无论如何它对我有用！希望这可以帮助！ :)

Answer 2

为了澄清 Rob Crowley 的回答，我使用 "vsomeip in 10 minutes" 教程中包含的两个独特的 .json 配置文件让它工作。我在提供服务的主机上使用 "World" 配置，在客户端运行主机上使用 "Hello" 配置文件。在这些文件中，我唯一需要修改的是 "unicast" 地址。我更改了它以匹配各个主机的 IP 地址。

我还修改了脚本以在 "route add -host" 命令之前使用 "sudo"，因为我发现没有它实际上不会添加路由。

我在 "vsomeip/build/examples/" 文件夹中调用了 make 来构建示例。我在服务脚本上指向的是 "notify-sample" 可执行文件 (vsomeip/build/examples/)。我在服务脚本上指向的是 "subscribe-sample" 可执行文件 (vsomeip/build/examples/).

在通过以太网连接我的两台主机并确保它们的 IP 地址与各自配置文件的 "unicast" 字段中的 IP 地址相匹配后，这种组合对我有效。
