[英]WCF service returns error method not allowed?
我知道互聯網上(包括此處)的文章很少,但是經過幾個小時,仍然找不到解決問題的方法。 我有一項將文件上傳到服務器的服務。 而且我收到http錯誤405,方法不允許。 到目前為止,嘗試一切都沒有成功。 以下是服務代碼。
服務合同:
// 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; }
}
服務等級:
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.

[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 };
}
}

對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>
解決此問題的方法是將服務合同聲明中的WebInvoke方法從“ POST”更改為“ *”。
我的WCF服務還提供了System.ServiceModel.ProtocolException {“遠程服務器返回了意外的響應:(405)不允許的方法。”},解決方案是在我的端點地址=“ http:末尾添加斜杠(/): //myhost/My.Service/“,完整的端點是
<endpoint
address="http://myhost/My.Service/"
binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding"
contract="My.Interfaces.IService"
name="myhost_IService_Client_Endpoint" />
