javascript - Web 服务方法名称无效

Question

当我尝试从 javascript 调用 webmethod 时出现以下错误“Web 服务方法名称无效”

System.InvalidOperationException: SaveBOAT Web Service method name is not valid. at System.Web.Services.Protocols.HttpServerProtocol.Initialize() at System.Web.Services.Protocols.ServerProtocol.SetContext(Type type, HttpContext context, HttpRequest request, HttpResponse response) at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)

HTML 代码:

<asp:LinkButton runat="server" ID="lnkAddBoat" OnClientClick="javascript:AddMyBoat(); return false;"></asp:LinkButton>

JS 代码:

function AddMyBoat() {
            var b = document.getElementById('HdnControlId').value;

            jQuery.ajax({
                type: "GET",
                url: "/AllService.asmx/SaveBOAT",
                data: { Pid: b },
                contentType: "application/text",
                dataType: "text",
                success: function(dd) {
                    alert('Success' + dd);
                },
                error: function(dd) {
                    alert('There is error' + dd.responseText);
                }
            });
}

C#代码(AllService.asmx文件中的Web方法)

[WebMethod]
public static string SaveBOAT(int Pid)
{
    // My Code is here
    //I can put anythng here
    SessionManager.MemberID = Pid;
    return "";
}

我尝试了在 Stack Overflow 和 ASP.NET 网站上找到的所有解决方案，但没有一个对我有用。

Answer 1

这是一个愚蠢的错误。

从方法声明中删除 Static 关键字。

[WebMethod]
public string SaveBOAT(string Pid)
{        
     SessionManager.MemberID = Pid;
     return "";
}
