工作灯HTTP适配器VS Ajax请求 [英] Worklight HTTP Adapter vs Ajax request

问题描述

什么是使用HTTP适配器工作灯IBM检索一个RESTful API，而不是一个Ajax请求数据的优势是什么？我觉得用Ajax是更快，为什么总会有使用这样的适配器？

What are the advantages of using an HTTP Adapter in Worklight IBM to retrieve data from a Restful API instead of an ajax request? I think that using ajax is faster so why would one use such an adapter?

推荐答案

看看的<一个href="http://pic.dhe.ibm.com/infocenter/wrklight/v6r0m0/index.jsp?topic=%2Fcom.ibm.worklight.help.doc%2Fdevref%2Fc_overview_of_ibm_worklight_adap.html"相对=nofollow>文档和<一href="http://www.ibm.com/developerworks/mobile/worklight/getting-started.html#server-side-development"相对=nofollow>入门模块。

适配器提供各种好处，具体如下：

Adapters provide various benefits, as follows:

• 快速发展：适配器开发JavaScript和XSL。开发者使用灵活，功能强大的服务器端JavaScript产生简洁易读code与后端应用程序和处理数据的整合。开发人员还可以使用XSL来分层后端数据转换成JSON。
• 只读和交易功能： IBM工作灯适配器支持只读和事务访问模式，后端系统
• 安全： IBM工作灯适配器使用灵活的验证设施，创建与后端系统的连接。适配器提供了与谁进行连接的用户的身份控制。用户可以是系统的用户，或委托他人交易是由用户。
• 透明度：从后端应用程序以统一的方式暴露检索，从而使应用程序开发人员可以统一访问数据，无论其来源，格式和协议的数据

• Fast Development: Adapters are developed in JavaScript and XSL. Developers employ flexible and powerful server-side JavaScript to produce succinct and readable code for integrating with back-end applications and processing data. Developers can also use XSL to transform hierarchical back-end data to JSON.
• Read-only and Transactional Capabilities: IBM Worklight adapters support read-only and transactional access modes to back-end systems.
• Security: IBM Worklight adapters use flexible authentication facilities to create connections with back-end systems. Adapters offer control over the identity of the user with whom the connection is made. The user can be a system user, or a user on whose behalf the transaction is made.
• Transparency: Data retrieved from back-end applications is exposed in a uniform manner, so that application developers can access data uniformly, regardless of its source, format, and protocol.
