WCF收到HTTP响应时发生错误 [英] WCF An error occurred while receiving the HTTP response

问题描述

这是我的WCF服务应该返回的内容。当我从ResponseModel中命令PaymentData并在该类中添加其他DataMember时。

Here's what my WCF service should be returning. When I command PaymentData out of ResponseModel and add other DataMembers in that class it works.

[DataContract]
public class ResponseModel
{
    [DataMember]
    public PaymentData PaymentData { get; set; }
}

以下是 PaymentData 类：

[DataContract]
public class PaymentData
{
    [DataMember]
    public PaymentType PaymentType { get; set; }
    [DataMember]
    public string CardNumber { get; set; }
    [DataMember]
    public DateTime ExpirationDate { get; set; }
    /// <summary>
    /// If true, then the CardNumber property will contain the token
    /// </summary>
    [DataMember]
    public bool IsCardNumberTokenized { get; set; }
    /// <summary>
    /// Number on back of credit cards. This value CANNOT be stored anywhere
    /// </summary>
    [DataMember]
    public string CardSecurityValue { get; set; }
    [DataMember]
    public CardSecurityPresence CardSecurityPresence { get; set; }
}

...以及中定义的枚举PaymentData 类

[DataContract(Name = "CardSecurityPresenceEnum")]
public enum CardSecurityPresence
{
    [EnumMember(Value = "1")]
    IsPresent = 1,
    [EnumMember(Value = "2")]
    Illegible = 2,
    [EnumMember(Value = "9")]
    NoCodeOnCard = 9,
    [EnumMember(Value = " ")]
    NotSent
}

[DataContract(Name = "PaymentTypeEnum")]
public enum PaymentType
{
    [EnumMember]
    Visa = CMPWSApiService.TransactionMop.VI,
    [EnumMember]
    MasterCard = CMPWSApiService.TransactionMop.MC,
    [EnumMember]
    AmericanExpress = CMPWSApiService.TransactionMop.AX,
    [EnumMember]
    Discover = CMPWSApiService.TransactionMop.DI,
    [EnumMember]
    PayPal = CMPWSApiService.TransactionMop.PP,
    [EnumMember]
    BillMeLater = CMPWSApiService.TransactionMop.BL
}

序列化不是我的变量名具有

Does the serialization not like that my variable names have the same names as their classes?

这是WCFTest Client的错误：

Here's the error from the WCFTest Client:

收到对
的HTTP响应[服务URL省略]时发生错误。该
可能是由于服务端点绑定未使用HTTP
协议引起的。这也可能是由于服务器终止了
的HTTP请求上下文（可能是由于服务关闭）。有关更多详细信息，请参见
服务器日志。

An error occurred while receiving the HTTP response to [service url omitted]. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

推荐答案

在 CardSecurityPresenceEnum 中，我有一个名为 NotSent 的枚举成员，该成员没有初始化为值。由于某种原因，这使事情挂起来。

In CardSecurityPresenceEnum I had a enum member called NotSent that was not initialized to a value. For some reason that was hanging things up.
