尝试使用此方法发送 URL 请求，但不起作用.... 网址是 -https://example.site/sendtp?otp="+randonnumber+"&number="+phoneNumber （添加了第 514,509 行参考）

    void sendotp(String phoneNumber)
    Random random = new Random();
    randonnumber=random.nextInt(999999);
    try 
        if (new ExtraOperations().haveNetworkConnection(getApplicationContext())) 
       [509]StringRequest request = new StringRequest(Request.Method.POST, "https://example.site/sendotp?otp="+randonnumber+"&number="+phoneNumber, new Response.Listener<String>() 
                @Override
                public void onResponse(String response) 
                    try 
                   [514]JSONObject jsonObject=new JSONObject(response);
                        JSONArray jsonArray=jsonObject.getJSONArray("result");
                        JSONObject jsonObject1=jsonArray.getJSONObject(0);

                        String success = jsonObject1.getString("success");

                        if (success.equals("1")) 

                        
                        else 
                            Toast.makeText(getApplicationContext(),"Something went wrong", Toast.LENGTH_LONG).show();
                        
                     catch (JSONException e) 
                        e.printStackTrace();
                    
                
            , new Response.ErrorListener() 
                @Override
                public void onErrorResponse(VolleyError error) 
                    error.printStackTrace();

logcat 错误是这个.. 不知道这是什么或如何修复...

【问题讨论】：

看来你在onResponse方法上得到的String response不能转换成JSONObject。尝试记录您的响应字符串以检查 Log.d("TAG", "response: " + response); 有什么问题 Log.d("TAG", "response:" + response);未在 logcat 中返回任何信息 【参考方案1】：
