xUtils怎么post请求上传json数据

//设置传输参数。
RequestParams params = new RequestParams("UTF-8");
try {
params.setBodyEntity(new StringEntity(gson.toJson(要转成json的对象),"UTF-8"));
params.setContentType("applicatin/json");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}

httpUtils.send(HttpMethod.POST, url,params,new RequestCallBack() {
@Override
public void onFailure(HttpException arg0, String arg1) {
return;
}
@Override
public void onSuccess(ResponseInfo responseInfo) {

if(responseInfo.statusCode == 200){
Log.i("MyLog", "发送成功");
}
}
});
