Question

我想在不使用Slack客户端的情况下通知Slack通道（不要问为什么）：

#!/usr/bin/env ruby
#Notification Script Test

slack_rooms = [ '#test_channel_notify' ]
slack_token_file = (File.join(ENV['HOME'], '.slack_api_token')
slack_api_token = (File.open(slack_token_file).readlines)[0].chomp
slack_url = "https://slack.com/api/chat.postMessage"
user = testuser
msg = 'This is a test message send'

data = {
        "token" => slack_api_token,
        "channel" => slack_rooms,
        "text" => msg,
        "username" => user
}

def send_slack_message(data)
    puts %x{curl -k -X POST -d" #{data}" '#{slack_url}'}
end

send_slack_message(data)

但是我遇到了一些奇怪的错误：

./Cap2.rb:21: syntax error, unexpected end-of-input, expecting ')'
send_slack_message(data)

有人指出我错过了)变量之后的结束slack_token_file：

#!/usr/bin/env ruby
#Notification Script Test

slack_rooms = [ '#test_channel_notify' ]
slack_token_file = (File.join(ENV['HOME'], '.slack_api_token'))
slack_api_token = (File.open(slack_token_file).readlines)[0].chomp
msg = 'This is a test message send'

data = {
        "token" => slack_api_token,
        "channel" => slack_rooms,
        "text" => msg,
}

def send_slack_message(data)
    slack_url = "https://slack.com/api/chat.postMessage"
    %x{curl -k -X POST -d" #{data}" '#{slack_url}'}
end

send_slack_message(data)

结果是：

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  

Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:00:50 --:--:--     0

当我现在运行脚本时，它会挂起Curl命令。有没有人有使用Slack API端点的经验？

您创建发送数据的方式看起来并不正确。根据{{3}}，它应该是JSON格式：

slack_rooms = ['#test_channel_notify']
slack_token_file = 'slack_token_file'
slack_api_token = 'slack_api_token'
msg = 'This is a test message send'

data = {
  "token" => slack_api_token,
  "channel" => slack_rooms,
  "text" => msg,
}

slack_url = "https://slack.com/api/chat.postMessage"
%{curl -k -X POST -d" #{data}" '#{slack_url}'}
# => "curl -k -X POST -d\" {\"token\"=>\"slack_api_token\", \"channel\"=>[\"#test_channel_notify\"], \"text\"=>\"This is a test message send\"}\" 'https://slack.com/api/chat.postMessage'"

您的代码正在创建的内容。

require 'json'
%{curl -k -X POST -d" #{data.to_json}" '#{slack_url}'}
# => "curl -k -X POST -d\" {\"token\":\"slack_api_token\",\"channel\":[\"#test_channel_notify\"],\"text\":\"This is a test message send\"}\" 'https://slack.com/api/chat.postMessage'"

这是Slack的API所期望的。

我建议不要在子shell中使用curl，而是建议利用Ruby的the documentation之一。
