Sinatra发送报头和正文

Question

我从一个web联系表单发布到sinatra。效果很好。我需要设置自定义标头，因为它是一个CORS请求，它的工作也很完美。

但是当我想返回一个json的回复请求:状态和:消息，我似乎发送一个sinatra对象，而不是正确的json。

如果我在日志中看到打印出来的消息，则消息不在正文中，而是在标题中。

代码片段:

    headers 
      "Access-Control-Allow-Origin" => "*",
      "Access-Control-Allow-Methods" => "POST",
      "Access-Control-Allow-Headers" =>  "Content-Type",
      "Access-Control-Max-Age" => "86400"
    if params[:email].empty?
      response[:status] = "error"
      response[:message] = "No email"
      p response.inspect
      body response.to_json
    elsif params[:mailbody].empty?
      response[:status] = "error"
      response[:message] = "No message?"
      body response.to_json
    elsif
...

问题解决

删除:

response[:status] = "error"
response[:message] = "No email"

添加:

{:status => "error", :message => "No email"}.to_json

可以
