Sinatra不显示POST数据

问题描述

我正在从客户端向Sinatra发送AJAX请求，但是不知为何数据没有显示.Chrome请求标头选项卡表明在客户端一切正常:

I am making AJAX request from the client to Sinatra but somehow the data doesn't show up.Chrome request headers tab suggests that on the client side is everything OK:

Request Payload 
{ test: Data }

但是，在Sinatra一侧

However, on Sinatra's side

  post '/api/check/:name' do
    sleep 3
    puts params.inspect
  end

和控制台:

 127.0.0.1 - - [03/Feb/2014 10:45:53] "POST /api/check/name HTTP/1.1" 200 17 3.0019
    {"splat"=>[], "captures"=>["name"], "name"=>"name"}

找不到发布数据，怎么了?

Post data is nowhere to be found, what's wrong ?

推荐答案

这是常见的错误.Sinatra只是解析表单数据(源).

It's a common fault. Sinatra just parse form data (source).

要解决此问题，请使用 rack-contrib 或 request.body .

To fix this use rack-contrib or the request.body.

Form参数如下所示

Form parameter would look like this

curl -X POST 127.1:4567/ -d "foo=bar"

您可以仅使用 request.body.read 或使用rack contrib代替参数.

Instead of params you can just use request.body.read or use rack contrib.

机架控制

1. 使用 gem install rack-contrib
安装

2. 要求

1. Install it with gem install rack-contrib

2. Require it

需要机架/容器"

加载它使用Rack :: PostBodyContentTypeParser

使用此方法，您可以像往常一样将 params 用于json发布数据.像这样:

With this you can use params as normal for json post data. Something like this:

curl -X POST -H "Content-Type: application/json" -d '{"payload":"xyz"}' 127.1:4567/
