美元.ajax POST到我的web服务工作正常，但GET请求失败错误405方法不允许

$.ajax POST to my webservice works fine but GET requests fail with error 405 Method not allowed

本文关键字：请求 GET 失败 错误 不允许 方法 POST ajax 我的 web 服务工作      更新时间：2023-09-26

一段时间以来，我一直在使用web服务，不管jquery $的目的是什么。ajax类型:"POST"。它总是能完成工作，所以我从来没有真正研究过使用type:"GET"。我今天刚刚测试了"GET"，因为我使用的这个插件(EXT Gantt)需要GET，我在Firebug中得到了这个方法不允许(405)错误。我认为我需要启用我的web服务来接受GET请求。我怎么做呢?

接口:

[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json)]
List<Task> GetAllTasks();
[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json)]
List<Dependency> GetAllDependencies();
类:

[DataContract]
public class Task
{
    [DataMember]
    public int Id { get; set; }
    [DataMember]
    public string Name { get; set; }
    [DataMember]
    public string StartDate { get; set; }
    [DataMember]
    public string EndDate { get; set; }
    [DataMember]
    public int PercentDone { get; set; }
    [DataMember]
    public int? ParentId { get; set; }
    [DataMember]
    public bool IsLeaf { get; set; }
    [DataMember]
    public string Responsible { get; set; }
    [DataMember]
    public int Duration { get; set; }
}
[DataContract]
public class Dependency
{
    [DataMember]
    public int From { get; set; }
    [DataMember]
    public int To { get; set; }
    [DataMember]
    public int Type { get; set; }
}

方法:

    public List<Task> GetAllTasks()
    {
        List<Task> Tasks = new List<Task>()
        {
        };
        Task temp = new Task();
        temp.Id = 0;
        temp.Name = "Planning";
        temp.StartDate = "2010-01-06T00:00:00";
        temp.EndDate = "2010-01-21T00:00:00";
        temp.PercentDone = 40;
        temp.ParentId = null;
        temp.IsLeaf = false;
        temp.Responsible = "John Doe";
        temp.Duration = 0;
        Tasks.Add(temp);
        return Tasks;
    }
    public List<Dependency> GetAllDependencies()
    {
        List<Dependency> Dependencies = new List<Dependency>()
        {
        };
        Dependency temp = new Dependency();
        temp.From = 11;
        temp.To = 12;
        temp.Type = 2;
        Dependencies.Add(temp);
        return Dependencies;
    }

Javascript/Ajax:(同样，当使用type: "POST"时，这可以完美地工作)

$.ajax({
    type: "GET",
    async: false,
    url: "Services/ProjectService.svc/GetAllDependencies",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (data, textStatus, xhr) { }
});
$.ajax({
    type: "GET",
    async: false,
    url: "Services/ProjectService.svc/GetAllTasks",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (data, textStatus, xhr) { }
});

网络。配置

  <system.serviceModel>
    <services>
      <service behaviorConfiguration="ProjectScheduler.Services.ProjectServiceBehavior" name="ProjectScheduler.Services.ProjectService">
        <endpoint address="" behaviorConfiguration="http" binding="webHttpBinding" bindingConfiguration="" contract="ProjectScheduler.Services.IProjectService">
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
  <bindings>
      <webHttpBinding>
          <binding name="webBinding">
              <security mode="Transport">
              </security>
          </binding>
      </webHttpBinding>
  </bindings>
<behaviors>
  <endpointBehaviors>
    <behavior name="http">
      <webHttp />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="ProjectScheduler.Services.ProjectServiceBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>

尝试将界面更改为

[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json, Method="GET")]
List<Task> GetAllTasks();
[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json, Method="GET")]
List<Dependency> GetAllDependencies();
