Slack API：无法发送附件

Question

我试图使用Slack的Python客户端发送附件，但每当我失败时。我试着将它与Tester一起发送，但它仍然不起作用。要么我得到{"ok": false,"error": "no_text"}或者如果我有文本属性只有文本将被发送。这就是我的做法。我也搜查了，但没有发现任何东西。

 attachment = json.dumps([{"attachments": [{"fallback": "Reddit Message","color": "#448aff","pretext":"You've got a new Message!","author_name": "Reddit","author_link": "https://reddit.com","author_icon": "imageurl","title": "Reddit Message","title_link": "https://reddit.com/message/inbox","text": "This is what I know about it.","fields": [{"title": "Author:","value": str(item.author),"short": "true"},{"title": "Subject: ","value": str(item.subject),"short": "true"},{"title": "Message:","value": str(item.body),"short": "false"}],"footer": "Reddit API","footer_icon": "anotherimageurl"}]}) 

sc.api_call("chat.postMessage",channel="U64KWRJAU",attachments=attachment,as_user=True) 

帮助将不胜感激。这应该是有道理的，但我不明白为什么它不起作用

Answer 1

从您的参考，您需要传递附件作为列表。您不需要在包含该列表的字典中输入密钥attachments。

attachment = json.dumps([ 
    { 
     "fallback": "Reddit Message", 
     "color": "#448aff", 
     "pretext":"You've got a new Message!", 
     "author_name": "Reddit", 
     "author_link": "https://reddit.com", 
     .... 
    } 
]) 

sc.api_call(
    "chat.postMessage", channel="U64KWRJAU", 
    attachments=attachment, as_user=True)
