POST请求不设置RequestParams会发生空指针异常，不会发生回调

[macangyewang123]

private static FormBody getRequestParams(RequestVersionBuilder versionParams) {
FormBody.Builder builder = new FormBody.Builder();
HttpParams params = versionParams.getRequestParams();
for (Map.Entry<String, Object> entry : params.entrySet()) {
builder.add(entry.getKey(), entry.getValue() + "");
ALog.e("params key:" + entry.getKey() + "-----value:" + entry.getValue());
}
return builder.build();
}
versionParams.getRequestParams()可能为空
