我已经尝试过某种方式，但响应总是为空， 但是我会用吐司和预期的方式发送数据
我也用邮递员检查数据按照键值发送的时间，然后结果是合适的。
这是我发送数据的代码

尝试在键值对中发送数据，请尝试以下代码：
HashMap<String, String> inputs = new HashMap<String, String>();
inputs.put("your key1", "value");
inputs.put("your key2", "value2");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
URL_PETANI_TERDEKAT, new JSONObject(inputs),
new com.android.volley.Response.Listener<JSONObject>() {
......
}

尝试使用getparams（）
添加此代码 @Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}
答案 2 :(得分：0)
问题已解决
我将objectRequest替换为成功发送的stringRequest参数
非常感谢你们
