Ajax call returns 200 OK 但没有调用 web 方法

Question

我有 ajax 调用如下

$.ajax({
  type: "POST",
  url: "MainPortal/VirtualRoomService.asmx/SaveJunit",
  data: JSON.stringify({
    xjunit: junit,
    data: editor.getData().trim()
  }),
  contentType: "application/json; charset=utf-8",
  async: false,
  dataType: "json",
  success: function(result) {
    if (result.d.split('|')[0] != "-1") {
      $("#<%=lblMessage.ClientID%>").text("Junit saved successfully");
    } else {
      $("#<%=lblMessage.ClientID%>").text(result.d.split('|')[1]);
    }
  },
  error: function(result) {
    if (result.status == 200 && result.statusText == 'OK') {} else {
      alert("FAILED : " + result.status + ' ' + result.statusText);
    }
  }

});

下面是 .asmx 网络服务中定义的 SaveJunit 代码

[WebMethod(EnableSession = true)]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string SaveJunit(string xjunit, string data)

ajax 总是调用 returns 200 OK 但函数从未被调用下面是从客户端调试器 (chrome)

捕获的请求数据

 {"xjunit":"<?xml version=\"1.0\" encoding=\"utf-8\"?><junit><byline>Mohan</byline><id></id><capid>102</capid><status></status><slug> 17</slug><tags>tags</tags><publication>21</publication><type><id>17</id><name>Text</name></type><label>21</label><deck>deck1</deck><intro>intro</intro><info><infodate></infodate><infotime></infotime><infoloc>loc</infoloc><infotext>info</infotext></info><createdby>7</createdby></junit>","data":"<p>content</p>"}

更新

我变了

error: function(result) {

到

error: function (jqXHR, textStatus, errorThrown) {

了解错误。 textStatus 显示为 parsererror 并且在 errorThrown 中显示意外的输入结束

Answer 1

更改此行：

data: JSON.stringify({xjunit: junit, data: editor.getData().trim()}),

至：

data: {xjunit: junit, data: editor.getData().trim()},

Answer 2

实际上 URL

MainPortal/VirtualRoomService.asmx

没有指向正确的位置。这是主要问题。将 URL 指向正确的位置已经解决了这个问题不知道为什么响应是 200 OK 对于一个坏的 URL？希望这个回答能对遇到类似问题的人有所帮助。
