如何从android发送原始JSON数据到PHP服务器？

Question

我想从android向php发送一些数据并在php中进行一些操作。我的问题是我无法通过我的php文件发送数据。我想将rawJson发送到php。 请帮帮我，我该怎么做。我试过这种方式..

btnRegister.setOnClickListener(new View.OnClickListener()
    {
        public void onClick(View view)
        {

            String name = inputFullName.getText().toString();
            String phone = inputPhone.getText().toString();
            String email = inputEmail.getText().toString();
            String password = inputPassword.getText().toString();
            String passwordrepeat = inputPasswordRepeat.getText().toString();
            if (checkdata(name, phone, email, password, passwordrepeat))
            {
                RegistroSolicitud oUsuario = new RegiterRequest();
                oUser.setName(name);
                oUser.setEmail(email);
                oUser.setPhone(phone);
                oUser.setPassword(password);
                Register(gson.toJson(oUser));
            }
        }
    });
