XMLHTTP在D.O.H中不可用

Question

我的D.O.H框架由nodejs運行。 （版本1.10）

我知道應該的NodeJS使用xmlhttprequest或其它模塊完成XHR請求。在我的情況下，我不是goona直接使用nodejs XHR，而是使用dojo的xhr代替。顯然，dojo的xhr無法運行nodejs。因爲沒有npm模塊，nodejs不能運行XHR。

是，任何可能性來解決這個問題？

命令：

node unittest.js load=doh test=test_custom_ajax.js

unittest.js：

global.dojoConfig = { 
    baseUrl: ".", 
    packages: [ 
    { name: "dojo", location: "./dojo" }, 
    { name: "dojox", location: "./dojox" }, 
    { name: "dijit", location: "./dijit" }, 
    { name: "my", location: "./my" } 
    ] 
} 
require("./dojo/dojo.js"); 

custom_ajax.js：

define([ 
    "dojo", 
    "dojo/_base/declare", 
    "dojo/_base/lang", 
    "dojo/request/xhr" 
], function(dojo, declare, lang, xhr) { 

    return declare("my.custom_ajax", null, { 

    ajaxGet: function(url, options) { 
     options = options || {}; 

     return xhr(url, { 
     method: "GET", 
     handleAs: "json", 
     headers: { 
      "Content-Type":"application/json", 
      "Accept":"application/json" 
     }, 
     }).then(
     lang.hitch(this, function(data) { 
      /* handle data */ 
      if (options.onHandle) {options.onHandle(resp)} 
      if (options.onLoad) {options.onLoad(resp)} 
      if (options.onComplete) {options.onComplete(resp)} 
     }), 
     lang.hitch(this, function(err) { 
      /* handle error */ 
      if (options.onError) {options.onError(resp)} 
     }) 
    ); 
    } 
    }); 
}); 

個

test_custom_ajax.js：

define([ 
    "doh/runner", 
    "my/custom_ajax" 
], function(doh, custom_ajax) { 
    doh.register("test_custom_ajax", [{ 
    var ca = new custom_ajax(); 
    var options = {}; 
    ca.ajaxGet('some_url', options); 
    }]); 
} 

結果：

Error: XMLHTTP not available

這裏是最終的解決方案：存根XHR之前負載的Ajax

test_custom_ajax.js

define([ 
    "doh/runner", 
    "dojo/node!sinon", 
    "dojo/request/xhr", 
    "dojo/Deferred" 
], function(doh, sinon, xhr, Deferred) { 

    doh.register("test_custom_ajax",[{ 

/*-------------------------------------------------- 
       stub xhr before load Ajax 
--------------------------------------------------*/ 
    // original xhr -> custom xhr 
    var oldXhr = require.modules["dojo/request/xhr"]["result"]; 
    var getDeferred; 
     require.modules["dojo/request/xhr"]["result"] = function(url, options) { 
     if (options.method === 'GET') { 
      getDeferred = new Deferred(); 
      return getDeferred; 
     } 
     }; 
     var Ajax; 
     require(["my/custom_ajax"], function(custom_ajax) { 
     Ajax = custom_ajax; 
     // custom xhr -> original xhr 
     require.modules["dojo/request/xhr"]["result"] = oldXhr; 
     }); 

     // prepare stub 
     var onHandleStub = sinon.stub(); 
     var onLoadStub = sinon.stub(); 
     var onCompleteStub = sinon.stub(); 
     var onErrorStub = sinon.stub(); 

/*------------------------------------------------*/ 

     // Inside this new Ajax, xhr is customized 
     var ca = new Ajax(); 

     // Normal AjaxGet 
     ca.ajaxGet('some_url', { 
     onHandle: onHandleStub, 
     onLoad: onLoadStub, 
     onComplete: onCompleteStub 
     }); 
     getDeferred.resolve(); //control xhr 
     /* assert stub */ 

     // Error AjaxGet 
     ca.ajaxGet('some_url', { 
     onError: onErrorStub, 
     }); 
     getDeferred.reject(); //control xhr 
     /* assert stub */ 
    }] 
); 
}
