正常に動作する Web アプリがいくつかありますが、何らかの理由で、サービスで関数を呼び出すたびに 500 エラーが返されます。

web.config ファイルは次のとおりです。

サービスを呼び出すメインの .cshtml の Javascript コードは次のとおりです。 // userUsername と userPassword は文字列変数です。

var TestConnectionParams = [{"username": userUsername, "password": userPassword}];

$.ajax({
    type: "POST",
    url: "/LoginService.svc/TestConnection",
    data: JSON.stringify(TestConnectionParams),
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (data) {
        var ReturnString = "Login returned " + data;
        $(OutputDiv).html(ReturnString);
    },
    error: function (HelpRequest, ErrorCode, TheError) {
        var ErrorMsg = "Login Failed:<br />" + TheError;
        $(OutputDiv).html(ErrorMsg);
    },
    async:false
});

サービスの .cs ファイルは次のとおりです。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.Text;
using System.Configuration;

namespace Web_Test
{
    [ServiceContract]
    public interface LoginServiceInterface
    {
        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
        String TestConnection(String username, String password);
    }

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

    public class LoginService : LoginServiceInterface
    {
        public String TestConnection(String username, String password)
        {
            String ReturnString = "This didn't do anything";

            return ReturnString;
        }
    }
}

AJAX 呼び出しは、「ログインに失敗しました: 内部サーバー エラー」を返します。

web.config で合理的に明らかな何かが欠けていると確信していますが、それを見ることができません。

THWACK - AJAX 呼び出しが 1 つの要素の配列 (要素が 2 つの文字列で構成される) を送信しているときに、サービスの .cs ファイル内の関数が 2 つの文字列を予期しているという事実が何か関係があるとは思わないでしょう。それと、あなたは？

将来この問題が発生する可能性がある方のために、修正された .svc.cs は次のとおりです。

namespace Web_Test
{
    public struct TestConnectionParams
    {
        public String username;
        public String password;
    }

    [ServiceContract]
    public interface LoginServiceInterface
    {
        [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
        String TestConnection(TestConnectionParams[] theParams);
    }

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

    public class LoginService : LoginServiceInterface
    {
        public String TestConnection(TestConnectionParams[] theParams)
        {
            String ReturnString = "Username is '" + theParams[0].username + ' and Password is {wouldn't you like to know}";
            // actually, password is theParams[0].password
            return ReturnString;
        }
    }
}
