从 Windows PHONE 8.1 调用时，WCF 服务不公开方法

Question

由于我使用的是 Windows phone 8.1，因此我无法像以前的应用程序那样调用我的 WCF 服务。

经过一番搜索，我找到了以下从 windows phone 8.1 调用服务的替代方法

try
{
    string responseBodyAsText;

    HttpResponseMessage res = await httpClient.GetAsync("http://localhost:50436/FabSvc.svc");
    res.EnsureSuccessStatusCode();

    string status = res.StatusCode + " " + res.ReasonPhrase + Environment.NewLine;
    responseBodyAsText = await res.Content.ReadAsStringAsync();
    responseBodyAsText = responseBodyAsText.Replace("<br>", Environment.NewLine); // Insert new lines
    string output = responseBodyAsText;
}
catch (HttpRequestException hre)
{
    string status = hre.ToString();
}
catch (Exception ex)
{
    // For debugging
    string status = ex.ToString();
}

此代码返回 OK 状态代码（见下文）以及一些基本数据。但我的问题是我无法从这一点上弄清楚如何访问任何方法。我做错了什么？

编辑：当前 WCF 服务（简化）

service.svc

namespace ServiceName.WCF
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class FabSvc : ICollection, ICompositionType
{
    /// <summary>
    /// Pings this instance.
    /// </summary>
    /// <returns></returns>
    public bool Ping()
    {
        return true;
    }

    /// <summary>
    /// Gets all CompositionTypes.
    /// </summary>
    /// <returns></returns>
    public List<CompositionTypeBase> GetAllCompositionTypes()
    {
        List<CompositionTypeBase> allCompositionTypes = new List<CompositionTypeBase>();
        try
        {
            allCompositionTypes = CompositionTypeBase.GetAllCompositionTypes();
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return allCompositionTypes;
    }
}

Icollection.cs

namespace ServiceName.WCF
{
    [ServiceContract]
    interface ICollection
    {
        [OperationContract]
        List<CollectionBase> GetAllCollections();
    }
}

CollectionBase.cs

namespace ServiceName.WCF.Entities
{
    public class CollectionBase
    {
        public int CollectionID { get; set; }

        public string Description { get; set; }

        /// <summary>
        /// Gets all seasons.
        /// </summary>
        /// <returns></returns>
        public static List<CollectionBase> GetAllCollections()
        {
            List<CollectionBase> allCollections = new List<CollectionBase>();
            IEnumerable<Collection> collections = Collection.GetAll();
            foreach (var collection in collections)
            {
                CollectionBase seasonBase = new CollectionBase();
                seasonBase.CollectionID = collection.CollectionID;
                seasonBase.Description = collection.Description;
                allCollections.Add(seasonBase);
            }
            return allCollections;
        }
    }
}

当您使用 HttpClient 时，您打算将数据发布到端点，因此这里没有合同。

通过添加引用或使用 wcfutil 创建代理时，您可以“看到”这些操作。

对于 RestFul 服务，您可以像这样简单地调用操作：

HttpResponseMessage res = await httpClient.GetAsync("http://localhost:50436/FabSvc.svc/GetAllCollections/value");

但是您的服务需要 SOAP 请求，因此您需要使用 SOAP/XML 发出请求才能使用您的方法。 在 SOAP 信封中，您可以通知服务您要执行的操作，如下所示：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <OperationName xmlns="http://tempuri.org/">

您还可以在 Header 中包含操作。 在下面的示例中，我使用了 WebClient：

using (var client = new WebClient())
{
    var data = GetSoap();
    client.Headers.Add("Content-Type", "text/xml;charset=utf-8");
    client.Headers.Add("SOAPAction", "\"http://tempuri.org/ICollection/GetAllCollections\"");
    var response = client.UploadString("http://localhost:50436/FabSvc.svc", data);
    Console.WriteLine(response);
}

希望对你有帮助
