此请求已被阻止，因为当用在 GET 请求中时，会将敏感信息透漏给第三方网站。若要允许 GET 请求，请将 JsonRequestBehavior 设置为 AllowGet。
1、问题描述
mvc从一个路径获取所有的图片信息，ajax方法如下：
function getimages(day) {var year = $("#selYear").val();var month = $("#selMonth").val();selday = day;var date = year + "." + month + "." + (day < 10 ? "0" + day : day);$("#selInfo").text(date);$("#fileContainer").html("");$.ajax({url: '@Url.Content("/MedOffice/Photo/ImageList")' + '?path=' + date,type: 'GET',dataType: 'text/json',success: function(data) {alert(data);},error: function(xmlHttpRequest, textStatus, errorThrown) {console.log(xmlHttpRequest);alert(xmlHttpRequest);}});}
调用执行返回如下结果：
2、问题分析
将json更改为jsonresult并设置为：
JsonRequestBehavior = JsonRequestBehavior.AllowGet//加上这一句
3、正确请求方法
public JsonResult ImageList(string path){List<FileInfoViewModel> files = new List<FileInfoViewModel>();try{var datetime = DateTime.Parse(path);var mypath = path.Replace(datetime.Year + ".", "");var destpath = "~/AllDocuments/" + datetime.Year + "/" + mypath;destpath = Server.MapPath(destpath);if (Directory.Exists(destpath)){foreach (string filepath in Directory.GetFiles(destpath)){FileInfoViewModel model = new FileInfoViewModel{Path = filepath,Name = Path.GetFileNameWithoutExtension(filepath)};try{var fileInfo = new FileInfo(filepath);model.Size = fileInfo.Length.ToString();model.Date = fileInfo.CreationTime.ToString("yyyy-MM-dd HH:mm:ss");}catch (Exception e){LogHelper.Error(e);}}}return new JsonResult(){Data = new{result = 0,messate = "",data = files},JsonRequestBehavior = JsonRequestBehavior.AllowGet};}catch (Exception e){LogHelper.Error(e);return new JsonResult(){Data = new{result = -99,messate = e.Message,data = files},JsonRequestBehavior = JsonRequestBehavior.AllowGet};}}
