机器人对用户的松弛响应

为我的应用程序编写一个僵尸用户,在向用户返回响应时错过了最后一步。

因此,一旦用户验证,我就存储了信息响应。在这里

{"ok":true,"access_token":"xoxp-SENSITIVEDATA_MAIN_ACCESSTOKEN-","scope":"identify,bot","user_id":"U2YT_SENSITIVE","team_name":"gsuresh","team_id":"T2Y_SENSITIVE","bot":{"bot_user_id":"U2Z_SENSITIVE","bot_access_token":"xoxb-SENSITIVE_BOT_ACCESSTOKEN"}}

使用来自rest客户端的信息,我试图从我的机器人攻击用户,但没有成功。这是我迄今为止所尝试的

尝试1:

网址: https://slack.com/api/chat.postMessage

有效载荷:

{
    "token": "xoxb-SENSITIVE_BOT_ACCESSTOKEN",   // used bot accees token 
    "channel": "U2YT_SENSITIVE", // user id 
    "text": "Whats up dude? I am bot",
    "as_user" :true    
}

答复:

{
"ok": false
"error": "not_authed"
"warning": "missing_charset"
} 

尝试2:

网址: https://slack.com/api/chat.postMessage

有效载荷:

{
    "token": "xoxp-SENSITIVEDATA_MAIN_ACCESSTOKEN",   // used main accees token 
    "channel": "U2YT_SENSITIVE",
    "text": "Whats up dude? I am bot",
    "as_user" :true    
}

答复:

{
"ok": false
"error": "not_authed"
"warning": "missing_charset"
}

原因可能是什么?我离开时没有任何线索。
