dojo - 如何在dojo.store.JsonRest 中设置header 为 "Accept"application/json put 或post 的时候？

Question

在 dojo.store.JsonRest 中如何设置 header "Accept"值为 application/json 的 puting 或 posting？

var dataStore = new dojo.store.JsonRest({
    target : "/project-services/"
});

dataStore.put({id: 10, field1: "Some Value", field2: "Other Value"});

当前发送的 header 是:

接受文本/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8

看起来头信息不是 PUT 和 POST 的选项，所以我决定简单地扩展 dojo.store.JsonRest。

/**
 * Extend the dojo.store.JsonRest
 */

if(!dojo._hasResource["ext.store.JsonRest"]) {
    dojo._hasResource["ext.store.JsonRest"] = true;
    dojo.provide("ext.store.JsonRest");
    dojo.require("dojo.store.JsonRest");
    dojo.extend(dojo.store.JsonRest, {
        put: function(object, options){
            options = options || {};
            var id = ("id" in options) ? options.id : this.getIdentity(object);
            var hasId = typeof id != "undefined";
            return dojo.xhr(hasId && !options.incremental ? "PUT" : "POST", {
                    url: hasId ? this.target + id : this.target,
                    postData: dojo.toJson(object),
                    handleAs: "json",
                    headers:{
                        "Content-Type": "application/json"
                        , "If-Match": options.overwrite === true ? "*" : null
                        , "If-None-Match": options.overwrite === false ? "*" : null
                        , "Accept": "application/javascript, application/json"
                    }
                });
        },
    });
}
