Question

我是从网络联系表发布到sinatra的。哪个效果很好。我需要设置自定义标头，因为它是一个CORS请求，它也很完美。

但是当我想要回复json请求：status和：message时，我似乎发送了一个sinatra对象而不是正确的json。

此外，如果我在日志中看到打印输出，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

...

日志文件：

"#<Sinatra::Response:0x007fc62bfed2f8 @status=200, @header={\"Content-Type\"=>\"application/json\", \"Access-Control-Allow-Origin\"=>\"*\", \"Access-Control-Allow-Methods\"=>\"POST\", \"Access-Control-Allow-Headers\"=>\"Content-Type\", \"Access-Control-Max-Age\"=>\"86400\", :status=>\"error\", :message=>\"No email\"}, @chunked=false, @writer=#<Proc:0x007fc62bfecf88@/Users/gtheys/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/rack-1.5.2/lib/rack/response.rb:27 (lambda)>, @block=nil, @length=0, @body=[]>"

Answer 1

问题解决了

删除：

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

添加：

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

它有效

sinatra发送标题和正文
