RoR:Ruby On Rails 的 Web Service

1.c:\rails flexstore

2.修改数据库配置文件 database.yml

3.c:\flexstore\ruby script/generate model product

4.c:\flexstore\ruby script/generate web_service ProductWervice getall find

5.修改如下两个 rb文件

product_service_api.rb class ProductServiceApi < ActionWebService::API::Base   api_method :getall,:returns => [[Product]]   api_method :find,    :expects => [{:from=>:int},{:to=>:int}],    :returns => [[Product]] end

product_service_controller.rb class ProductServiceController < ApplicationController   wsdl_service_name 'ProductService' web_service_scaffold :invoke #此处可以像.NET一下直接在浏览器测试web service def getall return Product.find_all   end def find return Product.find(:all,:conditions =>["price >= :from and price <= :to",params])        end end

6. C:\flexstore\ruby script/server

7. http://localhost:3000/Product_Service/service.wsdl

wsdl <definitions name="ProductService" targetNamespace="urn:ActionWebService"> − <types> − <xsd:schema targetNamespace="urn:ActionWebService"> − <xsd:complexType name="ProductArray"> − <xsd:complexContent> − <xsd:restriction base="soapenc:Array"> <xsd:attribute wsdl:arrayType="typens:Product[]" ref="soapenc:arrayType"/> </xsd:restriction> </xsd:complexContent> </xsd:complexType> − <xsd:complexType name="Product"> − <xsd:all> <xsd:element name="id" type="xsd:int"/> <xsd:element name="name" type="xsd:string"/> <xsd:element name="description" type="xsd:string"/> <xsd:element name="price" type="xsd:double"/> <xsd:element name="image" type="xsd:string"/> <xsd:element name="triband" type="xsd:int"/> <xsd:element name="camera" type="xsd:int"/> <xsd:element name="video" type="xsd:int"/> </xsd:all> </xsd:complexType> </xsd:schema> </types> <message name="Getall"> </message> − <message name="GetallResponse"> <part name="return" type="typens:ProductArray"/> </message> − <message name="Find"> <part name="from" type="xsd:int"/> <part name="to" type="xsd:int"/> </message> − <message name="FindResponse"> <part name="return" type="typens:ProductArray"/> </message> − <portType name="ProductServiceProductServicePort"> − <operation name="Getall"> <input message="typens:Getall"/> <output message="typens:GetallResponse"/> </operation> − <operation name="Find"> <input message="typens:Find"/> <output message="typens:FindResponse"/> </operation> </portType> − <binding name="ProductServiceProductServiceBinding" type="typens:ProductServiceProductServicePort"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc"/> − <operation name="Getall"> <soap:operation soapAction="/product_service/api/Getall"/> − <input> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="urn:ActionWebService" use="encoded"/> </input> − <output> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="urn:ActionWebService" use="encoded"/> </output> </operation> − <operation name="Find"> <soap:operation soapAction="/product_service/api/Find"/> − <input> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="urn:ActionWebService" use="encoded"/> </input> − <output> <soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="urn:ActionWebService" use="encoded"/> </output> </operation> </binding> − <service name="ProductServiceService"> − <port name="ProductServiceProductServicePort" binding="typens:ProductServiceProductServiceBinding"> <soap:address location="http://localhost:3000/product_service/api"/> </port> </service> </definitions>

8.测试 http://localhost:3000/Product_Service/invoke

9.使用自己定义的结构

#model class ReportStruct < ActionWebService::Struct   member :id, :int   member :CreateDate,:string   member :UpdateDate,:string   member :user_id,:int   member :Content,:string   member :username,:string end #Controller def reports_find(userid) if userid != 0       reports = Report.find(:all,:conditions => ["user_id= :userid",params],:order => "CreateDate desc") else       reports = Report.find(:all,:order => "CreateDate desc")     end     results = []     reports.each do |rec|        results << ReportStruct.new(:id => rec.id, :CreateDate => rec.CreateDate,            :UpdateDate => rec.UpdateDate, :user_id => rec.user_id,            :Content => rec.Content,:username => rec.user.DisplayName)     end return results     end
