Question

我正在尝试将params的哈希传递给sinatra中的post post资源中的函数，请参阅下文。

post '/service' do
   create_itop_entry(params)
end

我的功能是我将params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

下面的函数调用返回我的预期结果...这是添加到我的json_data的哈希值。当我从sinatra打印出params.inspect时，它会返回与下面相同的哈希值。

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Array隐式转换为String ...我是ruby / sinatra的新手，所以我可能会错过一些简单的...

您的函数返回一个哈希值。这不是return from a Sinatra route的有效类型。返回哈希导致Web服务器混淆，导致此错误。

也许您的意思是调用to_json并返回结果字符串？

Sinatra将params作为哈希函数传递
