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

... 27 moreC# 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
我看到demo
[url]http://www.lwhbj.com/unity3d/Documentation/ScriptReference/WWWForm.html[/url]
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;
}
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。
[code="java"] WWWForm： Helper class to generate form data to post to [color=red]web servers [/color] [/code]注意是 web servers 。
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！
