通过dojo.data和WikipediaStore灵活创建Web Service

Revin Guillen发布了一个Dojo dojo.data API，你能够用优雅的方式使用web service

dojox.data.WikipediaStore能够把Wikipedia当作简单对象进行查询。这里是完整例子：demo

你只需要：

1。创建一个Web service对象

2。为ServiceStore申明一个新的数据存储

3。提供一个提取函数

4。提供一个返回结果的_processResults函数


server 代码

{
        "SMDVersion": "2.0",
        "id": "http://en.wikipedia.org/w/api.php",
        "description": "Wikipedia API",

        transport: "JSONP",
        envelope: "URL",
        additionalParameters: true,
        target: "http://en.wikipedia.org/w/api.php",
        parameters: [
            { name: "format", optional: false, "default": "json" }
        ],

        services: {
            query: {
                parameters: [
                    { name: "action", type: "string", "default": "parse" }
                ]
            }
        }

}

{
	    "SMDVersion": "2.0",
	    "id": "http://en.wikipedia.org/w/api.php",
	    "description": "Wikipedia API",
	 
	    transport: "JSONP",
	    envelope: "URL",
	    additionalParameters: true,
	    target: "http://en.wikipedia.org/w/api.php",
	    parameters: [
	        { name: "format", optional: false, "default": "json" }
	    ],
	 
	    services: {
	        query: {
	            parameters: [
	                { name: "action", type: "string", "default": "parse" }
	            ]
	        }
	    }
	
}

store代码：
 

dojo.require("dojo.io.script"); // for cross domain JSONP
dojo.require("dojox.rpc.Service");

dojo.addOnLoad(function(){
    var mu = dojo.moduleUrl("dojox.rpc.SMDLibrary", "wikipedia.smd");
    var wikipedia = new dojox.rpc.Service(mu);

    wikipedia.query({
        action: "parse",
        page: "Main Page"
    }).addCallback(this, function(article){
        dojo.body().innerHTML = article.parse.text["*"];
    });
});

dojo.require("dojo.io.script"); // for cross domain JSONP 	
dojo.require("dojox.rpc.Service"); 	
  	
dojo.addOnLoad(function(){ 	
    var mu = dojo.moduleUrl("dojox.rpc.SMDLibrary", "wikipedia.smd"); 	
    var wikipedia = new dojox.rpc.Service(mu); 	
  	
    wikipedia.query({ 	
        action: "parse", 	
        page: "Main Page" 	
    }).addCallback(this, function(article){ 	
        dojo.body().innerHTML = article.parse.text["*"]; 	
    }); 	
});
