我正在尝试以下方法: [System.Web.Http.AcceptVerbs("PUT")] public HttpResponseMessage MakePost(PostDto post) { try { var response = Request.CreateResponse(HttpStatusCode.Redirect); // tried MOVED too response.Headers.Location = new
[System.Web.Http.AcceptVerbs("PUT")] public HttpResponseMessage MakePost(PostDto post) { try { var response = Request.CreateResponse(HttpStatusCode.Redirect); // tried MOVED too response.Headers.Location = new Uri("google.com"); return response; } catch (Exception e) { ErrorSignal.FromCurrentContext().Raise(e); return Request.CreateResponse(HttpStatusCode.InternalServerError, e); } }
这似乎是部分工作 – 当调用它时,我在chrome调试器中看到POST请求. “响应”选项卡中没有任何内容,但随后我看到发送到新URI的GET请求,但页面永远不会更改,并且我的AJAX调用会引发错误:
var options = { url: postUrl, type: type, dataType: 'json', xhrFields: { withCredentials: true } }; return $.ajax(options) .done(function (response) { // do stuff }) .fail(function (response) { alert('error) // this gets hit - shouldn't the browser have redirected at this point? }).complete(function () { // stuff }); };
如果我检查响应,我看到状态200“OK”……我很困惑.
我究竟做错了什么?
发生这种情况是因为发出AJAX请求的代码遵循重定向,而不是浏览器.这将失败,因为AJAX请求尝试访问其他域.如果要重定向浏览器,则应返回一些JSON结果或自定义HTTP标头,在jQuery中手动选择它,并在那里进行重定向.在你的控制器中:
var response = new HttpResponseMessage(HttpStatusCode.OK); response.Headers.Add("FORCE_REDIRECT", "http://google.com");
然后为AJAX调用添加成功回调:
success: function(data, textStatus, jqXHR) { if (jqXHR.getResponseHeader('FORCE_REDIRECT') !== null){ window.location = jqXHR.getResponseHeader('FORCE_REDIRECT'); return; } }
在过去,我已将控制器结果包装在自定义操作结果类中以供重用.
