关于unity3d与java客户端通信传图片的问题10

最近项目中用到了unity，需要在unity中截图，并通过webservices将截图信息传递到java服务器端上。但是在java服务器端上出现了问题，我查了资料不知道如何解决，求指点！！

这个是我在unity中写的截取图像的代码，图片信息需要通过WWWFORM上传到java服务器端上

public byte[] shot()
    {
        int width = Screen.width;
        int height = Screen.height;
        Texture2D tex = new Texture2D(width, height, TextureFormat.RGB24, false);
        byte[] bytes = tex.EncodeToPNG();
        return bytes;
    }

    public void getScreenshotByUrl(string data) {
        StartCoroutine(GetScreenshot(data));
    }

    public IEnumerator GetScreenshot(string data)
    {

        byte[] result = shot();
        IDictionary jsonDic = (IDictionary)Json.Deserialize(data);
        string normalUrl = (string)jsonDic["normalUrl"];        
       
        string time = string.Format("{0:yyyyMMddHHmmss}", DateTime.Now);
       
        //创建一个Web表单
	    WWWForm form = new WWWForm();
	    form.AddField("arg0", time);
        form.AddBinaryData("arg1", result);


        WWW www = new WWW(normalUrl.ToString(), form);
        yield return www;

        if (www.error != null)
            print(www.error);
        else
            print("Finished Uploading Screenshot");

    }

这个是在JAVA中的服务器端的webservices代码

	
	@Override
	public int insertPic(String name,byte[] content) throws Exception {
		
		System.out.println(content);
		System.out.println(name);
		return (Integer) null;
	}

这个是后台报的错误

采纳的答案

C# 有读取文件流的方法吧。只需要u3d脚步里面获取默认图片的位置，那么随便百度一个c# 上传文件。模拟post提交http请求。。。那么这样请求java服务器上传图片的方法。。
c# 只是模拟一次http请求传参而已

我用Unity4.5，form.AddField 和 form.AddBinaryData同时使用，从servlet中获取参数全都是null，只用AddField可以正常获取，使用AddBinaryData为null
请指教！

你不该用webservices来接收上传上来的文件。你直接用个servlet接收就行了。那个wwwFrom你可以认为是以表单的方式上传文件。

 WWWForm：  Helper class to generate form data to post to [color=red]web servers [/color]

注意是 web servers 。

如果想要改变默认的图片位置：
送你个脚本：
private var www:WWW;
private var image:Texture;
private var path:String;
function Start () {
   if(Application.platform==RuntimePlatform.Android){
      path=Application.persistentDataPath;
   }else if(Application.platform==RuntimePlatform.WindowsPlayer){
      path=Application.dataPath;
   }else if(Application.platform==RuntimePlatform.WindowsEditor){
      path=Application.dataPath;
      path=path.Replace("/Assets",null);
    }
   www=new WWW("file://"+path+"/Screenshot.png");
   yield www;
   image=www.texture;
}
