Question

我创建了一个JsonObjectRequest，用于将JSONObject发送到我的WebService。当我尝试发送这个JSONObject时，对象正在发送，但是发送3个对象而不是1.在我的数据库中，添加了3个对象。我无法理解为什么会出现这个问题，因为我总是发送1个JSONObject但是在webservice中发送了3个对象。

我尝试使用Google Chrome的Postman，并使用Postman正常发送1个JSONObject。

可能是什么？

尝试执行以下操作：

app.setRetryPolicy(new DefaultRetryPolicy(
            MY_SOCKET_TIMEOUT_MS, 
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES, 
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

您可以在此处更改超时（MY_SOCKET_TIMEOUT_MS）并更改尝试次数（DefaultRetryPolicy.DEFAULT_MAX_RETRIES）

Volley JsonObjectRequest在同一个请求中发送3个JSONObject？
