rocket.chat - 如何通过Rocket.chat中的rest api获取未读消息

Question

你好，我已经使用这个 https://docs.rocket.chat/api/rest-api/methods/channels/history 通过 rest API 获取未读消息。
示例调用

( https://rcserver.rocket.chat/api/v1/im.history?roomId=ByehQjC44FwMeiLbX?&unreads=true )

(https://rcserver.rocket.chat/api/v1/im.history?roomId=ByehQjC44FwMeiLbX?&unreads=”+ 真)

代码

HttpClient client = new HttpClient();
client.BaseAddress = new Uri(Constants.CONST_SITEURL);
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("X-Auth-Token", authToken);
client.DefaultRequestHeaders.Add("X-User-Id", userRcId);
HttpResponseMessage msgHistory = client.GetAsync(Constants.CONST_CHATHISTORY + userDetail.RC_RoomID + "&count=20&unreads=true").Result;
     if (msgHistory.IsSuccessStatusCode)
         {
           using (HttpContent content = msgHistory.Content)
                   {
                      var result = content.ReadAsStringAsync();
                      value = JObject.Parse(result.Result);
                    }
           directChatWindow = JsonConvert.DeserializeObject<DirectChatWindowBO>(value.ToString());
         }

我尝试使用上面的链接和代码，但结果不会给出任何未读的属性
示例结果

  },

  "_updatedAt": "2017-08-16T11:07:53.583Z"
}]
}

请帮帮我。
谢谢你。

作为 Rocket.Chat REST API 的维护者，您实际上让我们注意到了一个已经存在很长时间的错误(因为我们从 Coffeescript 转换而来)。我已提交 pull request它解决了这个问题，但是要显示未读内容，它确实需要更改您使用 im.history 的方式。端点。

要显示未读，您还必须传入 oldest 的查询参数这是一个可以成功转换为 JavaScript Date 对象的字符串，参见 Date.parse() documentation for details .

示例查询 url 如下所示:

http://localhost:3000/api/v1/channels.history?roomName=general&unreads=true&oldest=2017-01-01

然后包含未读信息的成功响应将如下所示:

{
    "messages": [
        {
            "_id": "pwiJmc7ZfEwebMEKP",
            "alias": "",
            "msg": "hello ;) ;)",
            "attachments": null,
            "parseUrls": true,
            "bot": null,
            "groupable": false,
            "ts": "2017-08-18T08:27:26.746Z",
            "u": {
                "_id": "HL2hEQSGask47a82K",
                "username": "graywolf336",
                "name": "graywolf336"
            },
            "rid": "GENERAL",
            "mentions": [],
            "channels": [],
            "_updatedAt": "2017-08-18T08:27:26.749Z"
        },
        {
            "_id": "YRch8iRsur7L6WF5B",
            "alias": "",
            "msg": "hello world",
            "attachments": null,
            "parseUrls": true,
            "bot": null,
            "groupable": false,
            "ts": "2017-08-18T08:21:50.072Z",
            "u": {
                "_id": "HL2hEQSGask47a82K",
                "username": "graywolf336",
                "name": "graywolf336"
            },
            "rid": "GENERAL",
            "mentions": [],
            "channels": [],
            "_updatedAt": "2017-08-18T08:21:50.073Z"
        }
    ],
    "firstUnread": {
        "_id": "3gJZbwLia6tuznPTk",
        "t": "uj",
        "rid": "GENERAL",
        "ts": "2017-07-31T22:53:20.579Z",
        "msg": "graywolf336",
        "u": {
            "_id": "HL2hEQSGask47a82K",
            "username": "graywolf336"
        },
        "groupable": false,
        "_updatedAt": "2017-07-31T22:53:20.579Z"
    },
    "unreadNotLoaded": 259,
    "success": true
}

截至 2017 年 8 月 8 日，在合并拉取请求之前，这将不起作用。然而，在合并之后，这将适用于开发版本，一旦版本 0.59 Rocket.Chat 已发布，然后您可以更新您的服务器并使用它。

希望这会有所帮助，如果您有任何问题，请告诉我，我会更新我的答案。
