我正在尝试执行POST抛出save方法。这是我的模特。
app.Models.Dummy = Backbone.Model.extend({
initialize: function () {
url = 'http://anotherdomain/Hello/';
},
});
当我执行时:
dummy.save({text : "greg"}, {
success : function(){
console.log('Ok!');
},
error: function(){
console.log('Error');
}
});
使用OPTIONS标头(代码200)触发请求,但永远不会触发POST请求。 但是当我执行时:
$.ajax({
type: 'POST',
url: "http://anotherdomain/Hello/",
data: {text:"greg"},
success: function(r) { alert(r.Result) },
dataType: "application/json"
});
它有效!
我是否需要覆盖骨干网中的某些内容?

这不是CORS的有效OPTIONS响应。响应需要包含告诉浏览器允许的标头。例如(取自MDN):
Access-Control-Allow-Origin: http://foo.example
Access-Control-Allow-Methods: POST, GET, OPTIONS
Access-Control-Allow-Headers: X-PINGOTHER
我知道你说$ .ajax工作但基于这个CORS响应我怀疑这是准确的并建议你仔细检查。在幕后,骨干本身就是使用$ .ajax
