Question

我正在使用php中的webservice开发一个android应用程序。一切都工作到现在。为了通信android和php我正在使用凌空库，一切正常但是这个。我不知道它是否是这样一个最大数量的参数或什么。一切都是真的，我测试了一些东西，当我发送一半参数“工作”时，它返回错误500，但至少它发送了一些东西。当我尝试发送所有参数时，会出现这个奇怪的错误。

这是我的代码，错误：

public void inserePagamento(final Context ctx, DocTed docTed,
        final ProgressDialog ringProgressDialog) {

    String url = "http://192.168.1.168/declabank/ws/public/transacaoDocTed";
    Encriptador cesar = Encriptador.getInstance();
    HashMap<String, String> params = new HashMap<String, String>();
    params.put("agencia", usuario.getAgencia());
    params.put("conta", usuario.getConta());
    params.put("cripto",cesar.encriptar(cesar.getChave(), usuario.getNome()));

    params.put("docFavorecidoNome", docTed.getNomeFav());

当任何参数值为null时，您将获得此异常。检查参数中的值参数。
