WCF 服务和 QuickBooks Web 连接器之间没有匹配的合同

Question

我正在尝试编写一个小型 SOAP 服务器，它连接到 QuickBooks Web 连接器，但我很难找到正确的合同。我总是收到以下错误：

网络连接器

由于 ContractFilter，方法 x 无法在接收方处理 EndpointDispatcher 不匹配。这可能是因为 合同不匹配（发送方和接收方之间的操作不匹配）或 发送方和接收方之间的绑定/安全不匹配。 检查发送者和接收者是否具有相同的合同和相同的 绑定（包括安全要求，例如消息、传输、 无）。

我创建了一个空的 ASP .NET Web 应用程序并添加了一个 WCF 服务。您将在这里找到authenticate 方法的 sn-p：

WCF 服务接口

[ServiceContract]
public interface IQuickBooks
{
    [OperationContract]
    AuthenticateResponse authenticate(Authenticate authenticateSoapIn);
}

WCF 服务实现

public class QuickBooks : IQuickBooks
{
    public AuthenticateResponse authenticate(Authenticate authenticateSoapIn)
    {
        return new AuthenticateResponse
        {
            AuthenticateResult = new[] { "1", "none" }
        };
    }
}

请求

[DataContract(Name = "authenticate")]
public class Authenticate
{
    [DataMember(Name = "strUserName", IsRequired = true)]
    public string Username { get; set; }

    [DataMember(Name = "strPassword", IsRequired = true)]
    public string Password { get; set; }
}

回应

[DataContract(Name = "authenticateResponse")]
public class AuthenticateResponse
{
    [DataMember(Name = "authenticateResult", IsRequired = true)]
    public string[] AuthenticateResult { get; set; }
}

Here 你可以从 QuickBooks 和my WSDL 输出中找到 WSDL。请注意，我只实现了authenticate 方法进行测试。我猜wsdl:types 不匹配会导致错误。在来自 QuickBooks 的原始 WSDL 中，authenticatetype 有两种基本类型：username 和 password。

如何使用 QuickBooks Web 连接器实现 WCF 服务？我做错了什么？

其他信息

堆栈跟踪

The message with Action 'http://developer.intuit.com/authenticate' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.  Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

Answer 1

此答案描述了如何使用 QuickBooks Web 连接器连接 WCF 服务（例如 authenticate 方法）。我不完全确定它是否是最好的实现，但它有效，我想帮助其他有类似问题的人。我们随时欢迎附魔和其他建议。

1. 创建一个空的 ASP .NET Web 应用程序
2. 添加 WCF 服务
3. 定义服务合同
4. 实现服务行为
5. 定义必要的数据类型

创建服务合同

[ServiceContract(Namespace = QuickBooks.URL, Name = "QuickBooks")]
public interface IQuickBooks
{
    [OperationContract(Action = QuickBooks.URL + "authenticate")]
    AuthenticateResponse authenticate(Authenticate authenticateSoapIn);
}

创建服务行为

[ServiceBehavior(Namespace = QuickBooks.URL)]
public class QuickBooks : IQuickBooks
{
    public const string URL = "http://developer.intuit.com/";

    public AuthenticateResponse authenticate(Authenticate authenticateSoapIn)
    {
        // Check if authenticateSoapIn is valid

        var authenticateResponse = new AuthenticateResponse();
        authenticateResponse.AuthenticateResult.Add(System.Guid.NewGuid().ToString());
        authenticateResponse.AuthenticateResult.Add(string.Empty);

        return authenticateResponse;
    }
}

实现请求和响应类型

请求

[DataContract(Name = "authenticate")]
[MessageContract(WrapperName = "authenticate", IsWrapped = true)]
public class Authenticate
{
    [DataMember(Name = "strUserName", IsRequired = true)]
    [MessageBodyMember(Name = "strUserName", Order = 1)]
    public string Username { get; set; }

    [DataMember(Name = "strPassword", IsRequired = true)]
    [MessageBodyMember(Name = "strPassword", Order = 2)]
    public string Password { get; set; }

    public Authenticate()
    {
    }

    public Authenticate(string username, string password)
    {
        this.Username = username;
        this.Password = password;
    }
}

回应

[DataContract(Name = "authenticateResponse")]
[MessageContract(WrapperName = "authenticateResponse", IsWrapped = true)]
public class AuthenticateResponse
{
    [DataMember(Name = "authenticateResult", IsRequired = true)]
    [MessageBodyMember(Name = "authenticateResult", Order = 1)]
    public ArrayOfString AuthenticateResult { get; set; }

    public AuthenticateResponse()
    {
        this.AuthenticateResult = new ArrayOfString();
    }

    public AuthenticateResponse(ArrayOfString authenticateResult)
    {
        this.AuthenticateResult = authenticateResult;
    }
}

ArrayOfString 用于authenticateResponse

[CollectionDataContractAttribute(Name = "ArrayOfString", Namespace = QuickBooks.URL, ItemName = "string")]
public class ArrayOfString : List<string>
{
}

此方案符合 SOAP 合同并允许数据交换。
