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，但是我找到正确的合同时遇到了一些麻烦。我总是得到以下错误：

网络连接器

由于ContractFilter，无法在接收方处理方法x   EndpointDispatcher不匹配。这可能是因为a   合同不匹配（发送方和接收方之间不匹配的操作）或   发送方和接收方之间的绑定/安全性不匹配。   检查发件人和收件人是否具有相同的合同   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。你会在这里找到authenticate方法的片段：

WCF服务接口

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

WCF服务实施

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; }
}

响应

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

Here您可以从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。我想错配wsdl:types会导致错误。在QuickBooks的原始WSDL中，authenticate type有username和password两种基本类型。

如何使用QuickBooks Web Connector实现WCF服务？我错了什么？

其他信息

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).

此答案描述了如何使用QuickBooks Web连接器（例如authenticate方法）连接WCF服务。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。随时欢迎附魔和其他建议。

创建一个空的ASP .NET Web应用程序
添加WCF服务
定义服务合同
实施服务行为
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;
    }
}

实施请求和响应类型

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;
    }
}

响应的

[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;
    }
}

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。
