c# - 如何使用 wcf 访问通过 phonegap 文件传输发送的文件？

Question

我试图通过 phonegap filetransfer.upload 将文件发布到 wcf 休息服务。当我将文件发送到服务时，我设法上传了所有文件，但后来我的日志显示不支持 HttpContext。我尝试允许 asp 兼容性要求，但无济于事，我发现与 webOperationContext 没有等效项。我会很感激任何帮助，我卡住了。这是相关代码：
接口：

[OperationContract]
[WebInvoke(UriTemplate = "putFile",
ResponseFormat = WebMessageFormat.Json,
Method = "POST") ]
     bool putFile();
}

执行：

   public bool putFile()
        {
            try
            {
                var request = OperationContext.Current.IncomingMessageProperties[HttpRequestMessageProperty.Name] as HttpRequestMessageProperty;
                String driverId = request.Headers["driverId"];
                HttpPostedFile file = HttpContext.Current.Request.Files["file"];

                String fileName = file.FileName;
                int _driverId = Int32.Parse(driverId);
                String fileURI = makeLocalPath(file.ContentType, fileName,driverId);

                if (file != null)
                {
                    Entities db = new Entities();

                    var uri = db.dt_media_uri.Where(p => p.driver_id == _driverId && p.uri_value.Equals(fileName));


                    using (Stream inputStream = file.InputStream)
                    {


                        FileStream fileStream = new FileStream(fileURI, FileMode.Create, FileAccess.Write, FileShare.Read);
                        if (fileStream == null)
                        {
                            try
                            {
                                inputStream.CopyTo(fileStream);
                            }
                            catch { return false; }
                            try
                            {
                                foreach (var v in uri)
                                {
                                    v.validated = true;
                                }
                            }

                            catch { EventLog.WriteEntry("Application", "unable to validate uri for driverID: " + driverId); }
                            try
                            {
                                db.SaveChanges();
                            }
                            catch { return false; }
                        }
                    }
                }
                return true;

            }
            catch(Exception e) { EventLog.WriteEntry("Application", "unable process filename\n"+e.ToString()); return false; }

这是来自客户：

options.chunkedMode = false;
options.headers = {
    driverId : self.driverId
};
console.log(JSON.stringify(options));
var ft = new FileTransfer();
ft.upload(path, encodeURI(self.serverPath + "/putFile"), fileSuccess,
        fileFail, options);
