我的问题是我正在创建一个包装器来处理与外部服务器（GeoNetwork）的连接并处理它的响应。
当我在我的搜索控制器中收到我的请求时，它工作正常。然后我尝试为包装器遵循此解决方案：
http://code.tutsplus.com/articles/writing-an-api-wrapper-in-ruby-with-tdd--net-23875
但是现在，我在webmock上遇到错误，我无法弄清楚原因。
module Wrapper
class Api
class << self
attr_accessor :base_uri
end
include HTTP
@base_uri = 'http://boldo.caiena.net:8080/geonetwork/srv/eng/'
builder_for_summary = Nokogiri::XML::Builder.new do |xml|
xml['csw'].GetRecords('xmlns:csw' => 'http://www.opengis.net/cat/csw/2.0.2',
'service' => 'CSW',
'version' => '2.0.2',
'resultType' => 'results',
# metadata records start at position 1
'startPosition' => '1',
'maxRecords' => '10') do
xml['csw'].Query('typeNames' => 'gmd:MD_Metadata') {
xml['csw'].Constraint('version' => '1.1.0'){
xml.Filter('xmlns' => 'http://www.opengis.net/ogc',
'xmlns:gml' => 'http://www.opengis.net/gml'){
xml.PropertyIsLike('wildCard' => '',
'singleChar' => '_'){
xml.PropertyName 'any'
xml.Literal '' #params[:search_field]
}
}
}
}
end
end
response = HTTP.post("#{@base_uri}csw", body: builder_for_summary.to_xml)
.with_headers(content_type: "application/xml")
.response
end
end
