如何将文件从android设备上载到restful wcf服务？

我正在构建一个Android应用程序，我需要上传一张用相机拍摄的照片。我需要将其上传到restful WCF服务。我看了很多教程，但似乎都不太管用。我认为我的问题在于WCF服务。我没有得到任何异常，但我得到了一个错误请求的响应。由于WCF服务目前正在我的本地主机上运行，因此我使用10.0.2.2从android emulator访问它。我可以在本地服务上调用其他服务方法，但此方法失败

我做错了什么？

在服务端使用WebHttpBinding原始编程模型是您的选择吗？请参阅博客文章，了解如何实现此功能的详细步骤说明。

对于任何遇到此问题的人，正如我刚才所做的那样，我需要更新我的WCF服务的maxReceivedMessageSize。这个问题有助于：

您是否能够从不同的客户端（例如，您在同一解决方案中创建的测试客户端）调用WCF方法？如果不是，那么问题可能在您的服务代码中，或者更可能在您的配置中。再说一遍，可能只是您尝试使用的URI不正确……是的。我使用Fiddler和emulator中的android浏览器调用了同一服务中的另一个方法。两者都起作用了。只是这个特殊的调用在我的android应用程序中不起作用。我认为你至少应该删除getExternalStorageDirectory（）背后的komma。你有没有想过这个问题？我现在也有同样的问题。谢谢
