当为客户端和服务器使用单独的 JSON 配置文件时，我无法在服务器和客户端之间建立通信我的要求是使用 vsomeip 框架传输 SOME/IP 数据。我在同一个系统上传输数据。但是，当对发送器和接收器使用相同的 JSON 文件时，我能够传输数据。下面是使用的 JSON 文件。

{
    "unicast" : "160.48.199.102",
    "logging" :
    { 
        "level" : "trace",
        "console" : "true",
        "file" : { "enable" : "false", "path" : "/tmp/vsomeip.log" },
        "dlt" : "false"
    },
    "applications" : 
    [
        {
            "name" : "master_tx",
            "id" : "0x1277"
        },
        {    
            "name" : "master_rx",
            "id" : "0x1344"
        }
    ],
    "services" :
    [
        {
            "service" : "0x3556",
            "instance" : "0x0001",
            "reliable" : { "port" : "30490", "magic-cookies" : "false" },
            "events" : 
            [
                {
                    "event" : "0x8001",
                    "is_field" : "true",
                    "is_reliable" : "false"
                }
            ]
        }
    ]
    "max-payload-size" : "5000",
    "max-payload-size-unreliable" : "5000",
    "routing" : "master_tx",
    "service-discovery" :
    {
        "enable" : "true",
        "port" : "30490",
        "protocol" : "_udp_",
        "initial_delay_min" : "100",
        "initial_delay_max" : "200",
        "repetitions_base_delay" : "200",
        "repetitions_max" : "15",
        "ttl" : "100",
        "cyclic_offer_delay" : "2000",
        "request_response_delay" : "1500"
    }
}

但是，当对发送器和接收器使用不同的 JSON 文件时，我无法建立任何连接。以下是使用的 JSON 文件。

server.json

    "unicast" : "192.168.0.178",
    "logging" :

        "dlt" : "false"
    },
    "applications" : 
    [
        {
            "name" : "master_tx",

        }
    ],
    "services" :

                    "eventgroup" : "0x001",
                    "events" : [ "0x8001" ]
                }

        "cyclic_offer_delay" : "2000",
        "request_response_delay" : "1500"
    }
}

客户端.json

    ],
    "clients" :

    ],

    "max-payload-size-unreliable" : "5000",
    "routing" : "master_rx",

        "cyclic_offer_delay" : "2000",
        "request_response_delay" : "1500"
    }
}

如果 JSON 文件有问题或者我遗漏了其他内容，有人可以帮助我吗？

服务器.json

  1. 端口 30490 被定义为可靠，而它被用作服务发现端口（这是不可靠的）。使用其他的，例如 30500。
  2. 我不确定“_udp_”是否是允许的值—— “udp”肯定是。

客户端.json

  1. “clients”标签指定用于连接特定服务的端口。在这种情况下，再次仅使用一个端口 30490，该端口已为服务发现定义。此外，在客户端中它被指定为不可靠，而在服务器中它是可靠的。除了文档中指定的：vsomeip 将采用列表的第一个空闲端口。如果找不到空闲端口，则连接将失败。 尝试使用其他端口或删除“客户端”标签进行测试。

  2. 我不确定“_udp_”是否是允许的值—— “udp”肯定是。
