如何在 slack C# 中上传多个附件

Question

我想在我的 post 消息呼叫中添加多个附件。

我正在使用此 post 中的示例代码

    public class SlackAttachment
    {
        public string fallback { get; set; }
        public string color { get; set; }
        public string pretext { get; set; }
        public string author_name { get; set; }
        public string author_link { get; set; }
        public string author_icon { get; set; }
        public string title { get; set; }
        public string title_link { get; set; }
        public string text { get; set; }
        public string image_url { get; set; }
        public string thumb_url { get; set; }
        public string footer { get; set; }
        public string footer_icon { get; set; }
    }


    public static void SlackPoster(string imgUrl, string channelName){

        string postedMessage = "MessageText";
        var sampleAttachment = new SlackAttachment[]

    {
     new SlackAttachment {
                fallback = "",
                text = "",
                color = "134f46",
                pretext = "",
                author_name = "",
                author_icon = "",
                author_link = "",
                title = $"",
                title_link = "",
                image_url = imgUrl,
             thumb_url = @"https://i.imgur.com/aFAA6tj.png\",
                footer = $"Posted at {DateTime.Now.Day}/" +
           $"{DateTime.Now.Month}/{DateTime.Now.Year}/ " +
           $"{DateTime.Now.Hour}:{DateTime.Now.Minute }",
                footer_icon = ""
                         }
    };

        var attachmentsJson = JsonConvert.SerializeObject(sampleAttachment);
        var data = new NameValueCollection();
        data["token"] = myToken;
        data["channel"] = channelName;
        data["as_user"] = "true";
        data["text"] = postedMessage;
        data["attachments"] = attachmentsJson;
        var client = new WebClient();
        var response = client.UploadValues("https://slack.com/api/chat.postMessage", "POST", data);
        string responseInString = Encoding.UTF8.GetString(response);
        Console.WriteLine(responseInString);

我创建了另一个附件变量 sampleAttachment2 和序列化它：

var attachmentsJson2 = JsonConvert.SerializeObject(sampleAttachment2);

但我不知道将两个附件添加到

中的正确语法

data["attachments"] object

感谢您的帮助

sampleAttachment 是一个 SlackAttachment 对象数组。要添加更多附件，只需将更多 SlackAttachment 对象添加到该数组即可。

示例：

var sampleAttachment = new SlackAttachment[]
{
    new SlackAttachment {
            fallback = "",
            text = "1st attachment"
    },
    new SlackAttachment {
            fallback = "",
            text = "2nd attachment",
    }
};

API 参数附件的正确语法是附件数组的数组作为 JSON 字符串。
