Question

尝试使用Node-Red中的Watson文档转换服务并进行以下有效负载设置并输入＆＃39;转换节点，它始终返回＆＃34;错误：丢失连接到服务器＆＃34; 。我认为document的设置是正确的，但很难找到使其有效的方法。

msg = {  
   payload:'http://www.nbcnews.com/tech/tech-news/got-parking-ticket-yup-there-s-app-n602566',
   normalized_html:{  
      "exclude_tags_completely":["script", "sup"],
      "exclude_tags_keep_content":["font", "em", "span"],
      "keep_content":{"xpaths":["//body/div[@id='content']"]},
      "exclude_content":{"xpaths":["//*[@id='footer']","//*[@id='navigation']"]},
      "keep_tag_attributes":["*"]
   }
}

有人可以为此提供帮助/建议吗？非常感谢你！

以下是来自命令＆＃34; cf logs＆＃34;：

Answer 1

问题确实存在于节点而不是您的代码。它已被修复并将很快发布到NPM，请确保重新启动Node-RED以获取Watson节点的最新版本。

参考：https://github.com/watson-developer-cloud/node-red-node-watson/pull/164

修改：Released in 0.4.8

Answer 2

这很可能是http代理的问题，请确保您通过HTTPS访问该网站

编辑：

这看起来像文档转换节点中的一个问题，你应该在他们的github页面上引发一个问题（github.com/watson-developer-cloud/node-red-node-watson）并包含日志输出。
