Sinatra 将参数作为散列传递给函数

Question

我正在尝试将参数的哈希值传递给我在 sinatra 中的 post 服务资源中的一个函数，见下文。

post '/service' do
   create_itop_entry(params)
end

我的函数正在将参数传递给....

def create_itop_entry(fields)
params = {'json_data' => '{"operation":"core/create",
                           "comment":"Service created on ' + Time.now.strftime("%Y-%m-%d") + '",
                           "class":"Service",
                           "fields":{
                              org_id: "'+ fields["org_id"] +'",
                              status: "' + fields["status"] + '",
                              stack_type: "' + fields["stack_type"] + '",
                              version: "' + fields["version"] + '",
                              hostname: "' + fields["hostname"] + '",
                              longitude: "' + fields["longitude"] + '",
                              latitude: "' + fields["latitude"] + '",
                              abbreviation_code: "' + fields["abbreviation_code"] + '",
                              name: "' + fields["name"] + '",
                              email: "' + fields["email"] + '",
                              apn: "' + fields["apn"] + '"
                           },
                           "output_fields":"id, friendlyname"
                          }'
         }
end

下面的函数调用 returns 我的预期结果...这是添加到我的 json_data 中的哈希值。当我从 sinatra 打印出 params.inspect 时，它 returns 与下面相同的散列。

puts create_itop_entry({"org_id"=>"4", "status"=>"pilot", "stack_type"=>"single", "version"=>"2.9.29", "hostname"=>"test.pilot.net", "longitude"=>"-81.20", "latitude"=>"41.20", "abbreviation_code"=>"zzz", "name"=>"Test-Test", "email"=>"test@testing.com", "apn"=>"TestRange1 10.36.192.80-28,TestRange2 10.131.201.0-24"})

我得到的错误是没有将数组隐式转换为字符串...我是 ruby/sinatra 的新手，所以我可能只是遗漏了一些简单的东西...

您的函数return是一个散列。这不是 return from a Sinatra route 的有效类型。返回哈希会导致网络服务器混淆，从而导致此错误。

也许您的意思是调用 to_json 和 return 结果字符串？

Sinatra passing params as a hash to function
