Question

我对ServiceStack和REST服务一般都很陌生，所以如果这是初级的，或者我完全走错了路，请原谅我......

我正在使用ServiceStack版本4.0.15，ORMLite和SQL Server。

我正在尝试在自定义Route上设置POST端点，该端口接受邮件正文中的JSON对象，并从该对象在数据库中创建记录。我现在连接它的方式，如果我POST到[localhost] / json / reply / CreatePatientRequest的默认ServiceStack路由，一切正常。但是，如果我使用自定义的[localhost] / patient路由，请求对象在到达我的服务时会包含所有空值。

首先，我有一名患者DTO：

public class Patient
{
    [AutoIncrement]
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int SSN { get; set; }
    ...
    public DateTime CreatedAt { get; set; }
}

这是我的要求：

[Route("/patient", "POST")]
public class CreatePatientRequest : IReturn<PatientResponse>
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int SSN { get; set; }
    ...
}

PatientResponse只是一个返回Id，First和Last名称以及Message的类。所有这些类都具有其他属性。这是我的服务：

public class PatientService : Service
    {
        private static string connectionString = ConfigurationManager.ConnectionStrings["ApiDbConnectionString"].ConnectionString;
        private static OrmLiteConnectionFactory dbFactory = new OrmLiteConnectionFactory(connectionString, SqlServerDialect.Provider);
        private static IDbConnection dbConn = dbFactory.OpenDbConnection();

        public PatientResponse Post(CreatePatientRequest request)
        {
            var response = new PatientResponse { Id = 0 };
            if (request.SSN == 0)
            {
                response.Message = "No SSN present in request. Please specify SSN and resend.";
                return response;
            }
            try
            {
                dbConn.Insert(new Patient
                {
                    FirstName = request.FirstName.ToString(),
                    LastName = request.LastName.ToString(),
                    SSN = request.SSN,
                    ...
                    CreatedAt = DateTime.Now
                });
                response.Message = "Record created successfully.";
            }
            catch (Exception ex)
            {
                response.Message = ex.Message;
            }

            return response;
        }
    }
}

同样，如果我POST到CreatePatientRequest的默认ServiceStack路由，一切都很好，数据库得到更新，我得到PatientResponse JSON返回。但是，如果我发布到我的自定义＆＃34; / patient＆＃34; Route，CreatePatientRequest请求对象具有所有空值。

有人请帮忙！谢谢！

响应正文是一堆HTML，当在Fiddler的WebView选项卡中查看时，显示了ServiceStack在...＆＃34;上生成的＆＃34; CreatePatientRequest快照，但是没有JSON响应。

使用像Fiddler这样的通用HTTP客户端使用请求正文（例如POST / PUT）创建原始JSON HTTP请求时，指定对您来说很重要＆＃ 39;使用Content-Type: application/json HTTP标头重新发送。

此外，根据您的服务的默认ContentType类型，您还应该使用Accept: application/json指定所需的响应类型，例如：

POST http://localhost:26809/patient HTTP/1.1
User-Agent: Fiddler
Content-Type: application/json
Accept: application/json
Host: localhost:26809
Content-Length: xxx

{"json":"string"}

在ServiceStack中设置默认ContentType

可以使用以下命令指定ServiceStack中的默认ContentType：

SetConfig(new HostConfig {
   DefaultContentType = MimeTypes.Json
});

使用POST到自定义Route时，ServiceStack JSON值为null
