Question

我知道互联网上的文章很少（包括这里），但几个小时后，仍无法找到问题的解决方案。我有一个服务，用于将文件上传到服务器。我得到http错误405，方法不允许。到目前为止，一切都没有成功。以下是服务代码。

服务合同：

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract(Name = "ExcelUpload.IUploadFile")]
public interface IUploadFile
{
    [OperationContract]
    [DataContractFormat]
    [WebInvoke(Method = "POST",
               UriTemplate = "Upload/",
               BodyStyle = WebMessageBodyStyle.Bare,
               ResponseFormat = WebMessageFormat.Json)]
    ReturnValue FileUpload(Stream File);
    // TODO: Add your service operations here
}


// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class ReturnValue
{
    [DataMember]
    public bool IsSuccessfull { get; set; }
}

服务类：

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
// NOTE: In order to launch WCF Test Client for testing this service, please select Service1.svc or Service1.svc.cs at the Solution Explorer and start debugging.
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple,
             InstanceContextMode = InstanceContextMode.PerCall,
             IgnoreExtensionDataObject = true,
             IncludeExceptionDetailInFaults = true)]
public class UploadFile : IUploadFile
{
    public ReturnValue FileUpload(Stream File)
    {
        using(FileStream writer = new FileStream(@"C:\temp", FileMode.Create))
        {
            int ReadCount = 0;
            var buffer = new byte[8192];
            while ((ReadCount = File.Read(buffer, 0, buffer.Length)) != 0)
            {
                writer.Write(buffer, 0, ReadCount);
            }
        }

        return new ReturnValue() { IsSuccessfull = true };
    }
}

对web.config的更正

<security>
  <requestFiltering allowHighBitCharacters="true">
    <verbs allowUnlisted="false">
      <add verb="POST" allowed="true"/>
      <add verb="GET" allowed="true"/>
    </verbs>
  </requestFiltering>
</security>

Answer 1

解决此问题的方法是从＆＃34; POST＆＃34;更改WebInvoke方法。到＆＃34; *＆＃34;在服务合同声明中。

Answer 2

我的WCF服务也提供了System.ServiceModel.ProtocolException {＆＃34;远程服务器返回了意外的响应：（405）方法不允许。＆＃34;} 解决方案是在我的端点地址=＆＃34; http：//myhost/My.Service/"中添加一个尾部斜杠（/）; 完整的端点是

  <endpoint
    address="http://myhost/My.Service/"
    binding="basicHttpBinding"
    bindingConfiguration="BasicHttpBinding"
    contract="My.Interfaces.IService"
    name="myhost_IService_Client_Endpoint" />

不允许WCF服务返回错误方法？
