Slack 机器人无法将消息发送到带有 - 或 space（例如 "channel-name"）的频道

Question

我的 slack bot 无法将消息发送到带有 space 或 - 类似“频道名称”的频道，但适用于单字频道。

  $curl = curl_init();

  curl_setopt_array($curl, array(
    CURLOPT_URL => "https://slack.com/api/chat.postMessage",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_POSTFIELDS =>"{ \"channel\": \"channel-withspace\",\"text\": \"hello\"}",
    CURLOPT_HTTPHEADER => array(
      "Content-Type: application/json",
      "Authorization: Bearer <here>"
    ),
  ));

  $response = curl_exec($curl);

  curl_close($curl);
  echo $response;

这里是错误：

{"ok":false,"error":"not_in_channel","warning":"missing_charset","response_metadata":{"warnings":["missing_charset"]}}

Answer 1

找到答案，原来我需要通过在频道中输入消息来邀请机器人：

/invite @channel-name

Answer 2

您可以将以下范围添加到您的机器人到 post 消息到 public 频道，而无需邀请机器人加入频道。

范围： chat:write.public

Send messages to channels @your_slack_app isn't a member of
