我有以下Gemfile:
source "http://rubygems.org"
gem 'sinatra', '1.3.2'
gem 'json', '1.6.4'
以下Sinatra应用程序:
require 'sinatra'
require 'json'
get '/ze/api/session.json' do
content_type :json
{ :name => 'name' }
end
当我提出像这样的基本要求时:
curl localhost:4567/ze/api/session.json
我明白了:

您尝试从路由返回哈希值,但哈希值不是something you can return here。
只需使用.to_json
将哈希值转换为json字符串,然后您可以返回(您需要json,但尚未使用它):
get '/ze/api/session.json' do
content_type :json
{ :name => 'name' }.to_json
end
