Question

我正在尝试使用pageres包获取网页图像，并使用hubot将图像发布到松弛状态。我能够获得图像，但由于某种原因，我无法使用松弛上传API将其发布到松弛状态。这是我的代码，你能告诉我什么可能是错的吗？（不是咖啡皮问题）

fs = require("fs")
Pageres = require('pageres') 
util = require("util")
request = require("request")
module.exports = (robot) ->
  robot.respond /screenshot page (\S*)?( at )?(\S*)?/i, (msg) ->
    pageres = new Pageres({delay: 30})
    domain = msg.match[1].replace("http://", "")
    if msg.match[3] == undefined
      size = '960x1024'
    else
      size = msg.match[3]
    dest = './screenshots'
    msg.send "Acquiring screenshot of #{domain}"
    pageres.src(domain, [size]).dest(dest)
    pageres.run (err) ->
      if err
    robot.logger.error err
       msg.send "Um..., you better check the log"
    else
    opts = {
      method: 'POST',
      uri: 'https://slack.com/api/files.upload',
      formData: {
        channels: process.env.HUBOT_SCREENSHOT_SLACK_CHANNEL,
        initial_comment: "Screenshot of #{domain}",
        token: process.env.HUBOT_SLACK_TOKEN,
        file: fs.createReadStream("#{dest}/#{domain}.png")
      }
    }

    request.post opts, (error, response, body) ->
      if error
        robot.logger.error error
      else
        robot.logger.debug 'screenshot posted to slack'
  return

僵尸程序连接到松弛，从松弛接收消息，解析它们并将图像恢复到本地目的地，但不能将其发布到松弛，日志中也没有错误。

Answer 1

您可以使用curl命令，该命令可以通过child_process调用以在通道中上传文件。

curl -F文件=@dramacat.gif -F频道= C024BE91L，＃general -F令牌= xxxx-xxxxxxxxx-xxxx https://slack.com/api/files.upload

Answer 2

您的 opts 变量中的 formData 属性似乎应该略有不同，如下所示：

formData: {
    token: process.env.HUBOT_SLACK_TOKEN,
    title: "Screenshot of #{domain}",
    filename: "image.png",
    filetype: "auto",
    channels: channel_id,
    file: fs.createReadStream("path_to_your_image"),
}

channel_id 是您的闲置频道ID，访问该频道时，您可以在浏览器地址栏中看到它。

无法通过hubot上传图像文件
