使用Backbone.js发布请求中的标头

我想在Backbone.js的REST服务的帖子请求中添加标题,我尝试两种方式:

this.model.save( { headers: {'X-Token' : myToken } } );

并使用setResquestHeader:

功能:

sendToken: function (xhr) {
        var tokenCookie;

        var name = "xtoken" + "=";
        var ca = document.cookie.split(';');
        for(var i=0; i<ca.length; i++) 
        {
            var c = ca[i].trim();
            if (c.indexOf(name)==0) tokenCookie = c.substring(name.length,c.length);
        }
          xhr.setRequestHeader('X-Token', tokenCookie);
        }
电话:

this.model.save({ 
                beforeSend: this.sendToken,

                success: function() {

                    alert("success");
                },
                error: function(model,response,options) {
                    alert("error");

                }

            });     

但它似乎不起作用,它不发送标题

Model.save的签名为model.save([attributes], [options])。您必须传递属性的空/空哈希才能添加选项:

this.model.save(null, {
    headers: {'X-Token' : 'myToken'}
});

演示http://jsfiddle.net/nikoshr/a4gss/

this.model.save(null, {
    beforeSend: function(xhr) {
        xhr.setRequestHeader('X-Token', 'set token');
    }
});
