在 Alfresco 中来自 WebScript 的 HTTP 请求 [英] HTTP Request from WebScript in Alfresco

问题描述

我正在使用 JS 控制器在 Alfresco 中编写 WebScript，我想向本地 HTTP 资源发出 HTTP 请求.此资源是一个基于 Java 的应用程序，并为我提供了自己的 REST API.

I'm writing a WebScript in Alfresco using JS controller and I want to make a HTTP request to the local HTTP resource. This resource is a Java-based app and gives me its own REST API.

我的 WebScript 不是共享组件:所以我没有 remote 对象来调用另一个 webscript.

My WebScript is not a Share Component: so I don't have a remote object to call another webscript.

如何从 WebScript 向本地资源(类似于/sdo/documents/getName?type=fl")发出 HTTP 请求?

How can I make a HTTP request to the local resource (something like '/sdo/documents/getName?type=fl') from a WebScript?

推荐答案

Alfresco 正在覆盖 Spring Surf webscripts.container bean，删除 remote 定义(在 <remote-api的code>web-scripts-application-context.xml):

Alfresco is overriding the Spring Surf webscripts.container bean removing the remote definition (in web-scripts-application-context.xml of remote-api):

<bean id="webscripts.container" class="org.alfresco.repo.web.scripts.RepositoryContainer" parent="webscripts.abstractcontainer">
      <property name="name"><value>Repository</value></property>
      <property name="scriptObjects">
         <map merge="true">
           <entry key="paging">
              <ref bean="webscripts.js.paging"/>
           </entry>
         </map>
<!-- ..... -->
</bean>

我建议您再次将其作为自定义 Javascript API 根级对象包含在内.

I suggest you include it again as a custom Javascript API root level object.

remote 根对象来自 Spring Surf框架，这意味着无论是针对 Alfresco 存储库还是共享开发 Web 脚本，您都拥有它.作为证明，这里是网络脚本 在公共 Alfresco CMIS 服务器中可用(-> Alfresco 存储库实例，如果要求您登录，则为 admin/admin):

The remote root object comes from the Spring Surf framework, meaning you have it regardless of being developing your Web Scripts against the Alfresco repository or Share. As a proof, here's the source for a Web Script available in the public Alfresco CMIS server (-> Alfresco repository instance, admin/admin if you are asked to login):

var serviceUrl = (args.service === null) ? "/api/repository" : args.service;
var conn = remote.connect("alfresco");
var result = conn.get(stringUtils.urlEncodeComponent(serviceUrl));

var service = atom.toService(result.response);
var workspace = service.workspaces.get(0);
model.repo = workspace.getExtension(atom.names.cmisra_repositoryInfo);

以下代码片段取自 spring-surf-application-context.xml，可在 Alfresco 的 spring-webscripts-1.0.0.CI-SNAPSHOT.jar 中找到3.4.0，这是remote根对象的定义:

The following snippet is taken from spring-surf-application-context.xml as found inside spring-webscripts-1.0.0.CI-SNAPSHOT.jar of Alfresco 3.4.0, which is where the remote root object gets its definition:

   <bean id="webscripts.container" parent="webscripts.abstractcontainer" class="org.springframework.extensions.webscripts.LocalWebScriptRuntimeContainer">
      <property name="name"><value>Spring Surf Container</value></property>
      <property name="registry" ref="webscripts.registry" />
      <property name="searchPath" ref="webframework.webscripts.searchpath" />
      <property name="templateProcessorRegistry" ref="webframework.webscripts.registry.templateprocessor" />
      <property name="scriptProcessorRegistry" ref="webframework.webscripts.registry.scriptprocessor" />
      <property name="scriptParameterFactoryRegistry" ref="webscripts.web.scriptparameterfactoryregistry" />
      <property name="configService" ref="web.config" />
      <property name="scriptObjects">
         <map merge="true">
            <entry key="remote" value-ref="webframework.webscripts.scriptremote" />
         </map>
      </property>
      <property name="processorModelHelper" ref="processor.model.helper"/>
      <property name="extensibilityModuleHandler" ref="webscripts.extensibility.handler"/>
   </bean>

   <bean id="webframework.webscripts.scriptremote" class="org.springframework.extensions.webscripts.ScriptRemote">
      <property name="configService" ref="web.config"/>
      <property name="connectorProvider" ref="webframework.connector.provider"/>
   </bean>
