如何克服此服务器错误并获得响应

Answer 1

得到了同样的错误。经过长时间的搜索我发现了这个在代码中添加setRetryPolicy

RequestQueue requestQueue = Volley.newRequestQueue(this);
    jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(DefaultRetryPolicy.DEFAULT_TIMEOUT_MS * 2, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
    requestQueue.add(jsonObjReq);

在Android E / Volley中使用volley时出现此错误：[3355] BasicNetwork.performRequest：意外的响应代码422
