我正在尝试使用phonegap文件传输API将图像从手机上传到WCF服务器。下面是我的代码。但我无法将图像上载到服务器。请提出一些建议

MyService.svc.cs

namespace MyAppService
{

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class MyService : IMyService
    {

        public string SaveImage()
        {
            HttpPostedFile file = HttpContext.Current.Request.Files["recFile"];
            if (file == null)
                return null;
            string targetFilePath = AppDomain.CurrentDomain.BaseDirectory + @"Images\Tree\\" + file.FileName;
            file.SaveAs(targetFilePath);
            return file.FileName.ToString();
        } 
}
}

谢谢你的帮助。。我发现了问题。。当我在WCF服务的web.config文件中设置aspNetCompatibilityEnabled=“true”时，我得到了HttpPostedFile

你应该试试这个

<configuration>
  <system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
  </system.serviceModel>
</configuration>

谢谢。

有什么错误？日志怎么说？System.NullReferenceException:对象引用未设置为对象的实例。在MyAppService.SaveImage（）中，我认为我的服务存在一些问题。HttpPostedFile=HttpContext.Current.Request.Files[“recFile”]；我能给你的最好的建议是，如果你有权访问Windows机器，那么就设置它，从设备代理它，然后检查从设备到服务器的数据包。在处理Cordova时，可能会有很多有趣的跨源问题。您是否独立测试了web服务？使用Google Chrome的扩展高级REST客户端进行测试

<configuration>
  <system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
  </system.serviceModel>
</configuration>
