JSON 与 Kodi (XBMC) 的 RPC 以重新启动播放列表中的第一项

JSON RPC with Kodi (XBMC) to restart first item in playlist

我正在使用 libjson (https://github.com/cinemast/libjson-rpc-cpp) 和 kodi 的 api(以前将 XBMC 称为 play/pause 并停止我的 Kodi 机器。但是,在我停止它,我不能再次用 play/pause 重新启动它。我使用的方法: 制作一个 json 文件,jsonrpcstub 可以处理,对于 play/pause 像这样:

[
{
    "name" : "Player.PlayPause",
    "description": "Pauses or unpause playback and returns the new state",
    "params": [
        {
            "$ref": "Player.Id",
            "name": "playerid",
            "required": true
        },
        {
            "$ref": "Global.Toggle",
            "default": "toggle",
            "name": "play"
        }
    ],
    "returns": {
        "$ref": "Player.Speed"
    },
    "type": "method"
}
]

然后我使用:

#include "xbmcremoteclient.h"
#include <jsonrpccpp/client/connectors/httpclient.h>

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#ifndef WIN32
    #include <termios.h>
#else
    #include <conio.h>
#endif
#include <unistd.h>
#include <time.h>

#include <iostream>

using namespace jsonrpc;
using namespace std;

int main(int argc, char** argv) {

    try {
        HttpClient httpclient("http://user:pass@tombrix.student.utwente.nl:8080/jsonrpc");
        XbmcRemoteClient stub(httpclient);
        stub.Player_PlayPause(0);
    } 
    catch(JsonRpcException& e) {
        cerr << e.what() << endl;
    }
    return 0;
}

为运行这个命令制作一个简单的可执行文件。 但是,当我尝试实现 goTo 函数时,这有效:http://kodi.wiki/view/JSON-RPC_API/v6#Player.GoTo

我做不到。我一直在将 json 文件更改为:

[
{"jsonrpc": "2.0", "method": "Player.PlayPause", "params": { "playerid": 0 }, "id": 1},
{
    "name": "Player.GoTo":,
    "params": [
        {
            "name": "playerid",
            "required": true
        },
        {
            "name": "to",
            "required": true,
            "type": [
                {
                    "enums": [
                        "previous",
                        "next"
                    ],
                    "type": "string"
                },
                {
                    "description": "position in playlist"
                }
            ]
        }
    ],
    "returns": {
        "type": "string"
    }
}
]

但是当我尝试通过 jsonrpcstub:运行 时,我不断收到语法错误:

Exception -32700 : JSON_PARSE_ERROR: The JSON-Object is not JSON-Valid:  specification file contains syntax errors

我最好只 运行 通过 jsonrpcstub 浏览到 http://myKodiMachine.xy:8080/jsonrpc 时得到的 json 文件,但这已经造成了语法错误。好像他的文件开头是这样的:

            "params": [
                {
                    "name": "addonid",
                    "required": true,
                    "type": "string"
                },
                {
                    "default": "",
                    "name": "params",

                            "type": "object"
                        },
                        {
                            "items": {
                                "type": "string"
                            },
                            "type": "array"
                        },
                        {
                            "description": "URL path (must start with / or ?",
                            "type": "string"
                        }
                    ]
                },
                {
                    "default": false,
                    "name": "wait",
                    "type": "boolean"
                }
            ],
            "returns": {
                "type": "string"
            },
            "type": "method"
        },
        "Addons.GetAddonDetails": {
            "description": "Gets the details of a specific addon",
            "params": [
                {
                    "name": "addonid",
                    "required": true,
                    "type": "string"
                },
                {
                    "$ref": "Addon.Fields",
由于某些奇怪的原因,

无效 JSON。任何指向能够从 linux(像这样或任何其他方式)停止和重新启动 kodi 中的播放列表的指示都将被认为是有帮助的。我特别需要这个,因为我播放了很多流,如果我暂停它们,它们会被缓冲(这不是很方便),所以我更喜欢 stop/restart 它们。

仍然不太满意 kodi 提供的 json 代码对 jsonrpc c++ 库毫无用处,但我设法让它工作,json 文件将需要这一行:

{"jsonrpc": "2.0", "method": "Input.ExecuteAction", "params": { "action": "play"}, "id": 1}

然后做:

stub.Input_ExecuteAction("play");

在 cpp 文件中,它将起作用:)。
