Question

我提供了一个WCF restful服务，用于将文件上传到服务器上的特定目录，一个可以上传文件的小型ASP.NET Web应用程序抛出了这个Web服务。问题是我经常收到拒绝访问的错误。我试图将所有权限授予用于测试目的的文件夹（对每个人的完全控制，对IIS_IUSRS的完全控制，WCF和Web服务的AppPool等），但仍然显示相同的错误。以下是服务和Web应用程序的代码：

主要WCF服务类

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple,
                 InstanceContextMode = InstanceContextMode.PerCall,
                 IgnoreExtensionDataObject = true,
                 IncludeExceptionDetailInFaults = true)]
    public class UploadFile : IUploadFile
    {
        public ReturnValue ExcelUpload(Stream File)
        {
            using (FileStream writer = new FileStream(@"C:\Users\Public\Documents", 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 };
        }

        public ReturnValue test(int id)
        {
            return new ReturnValue() { IsSuccessfull = true };
        }
    }

WCF服务合同

[ServiceContract(Name = "ExcelUpload.IUploadFile")]
public interface IUploadFile
{
    [OperationContract]
    [DataContractFormat]
    [WebInvoke(Method = "*",
               UriTemplate = "UploadExcel/",
               BodyStyle = WebMessageBodyStyle.Bare,
               ResponseFormat = WebMessageFormat.Json)]
    ReturnValue ExcelUpload(Stream File);
    // TODO: Add your service operations here

    [OperationContract]
    [DataContractFormat]
    [WebInvoke(Method = "POST",
               UriTemplate = "test/",
               BodyStyle = WebMessageBodyStyle.Bare,
               ResponseFormat = WebMessageFormat.Json)]
    ReturnValue test(int id);
}


// 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; }
}

Answer 1

非常基本的是，你为什么要为目录创建对象？

@＆＃34; C：\用户\公共\文件＆＃34;

尝试更改为@＆＃34; C：\ Users \ Public \ Documents \ MyFile.txt＆＃34;

在这里，您可以使用任何类型的文件而不是txt。并且不要忘记为要上传的文件设置限制。

希望它有帮助..！

尝试上传文件时，WCF休息服务访问被拒绝了吗？
