Question

我真的是Android上的新手，正在登录系统上工作，我正在使用凌空发布数据....我遇到的问题是当我尝试读取响应时。 .. 响应如下所示：

{“ st”：“否”，“消息”：“错误”}

我正在尝试仅访问st或message，有没有办法做到这一点？我尝试做：

response [i] ----发现扩展了数组类型'org.json.JSONObject'

 JsonObjectRequest jsonRequest = new JsonObjectRequest(Request.Method.POST, url, params, new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) { 
                    Log.e(TAG, "Response: " + response.length());
                    for (int i = 0; i < response.length(); i++) {
                        Log.e(TAG, "Values: " + response);
                    }
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    error.printStackTrace(); 
                }
            });

            Volley.newRequestQueue(this).add(jsonRequest);

Answer 1

您可以使用

response.getString("Message")

从给定的JSON获取消息

Answer 2

Sub FindPl()
    dim i as long, wb as workbook, OUTPUTRANGE as range, SEARCHRANGE as range
    set wb = "C:\Users\chenj5\Documents\Meeting_Jan_2019\simulation of Z1.9 for Ultra Multi-Focal\Meeting 0220\Dataset used for simulation.xlsx" 'added xlsx extension
    with wb
        set OUTPUTRANGE = .range(.cells(5,"D"),.cells(100,"D")) 'guessed... the range with the desired output
        set SEARCHRANGE = .range(.cells(5,"B"),.cells(100,"B")) 'guessed... the range where you will find .cells(i,"DE")
    end with
    with activeworkbook.sheets(1) 'FIX THIS TO FIT YOUR NEEDS
        For i = 2 To 1730
            If .Cells(i, "DE").Value > 3.9 Then 'FIXED SYNTAX ERROR
                .Cells(i, "DI").Value = 0
            Else: 
                .Cells(i, "DI").Value = Application.Index(OUTPUTRANGE, Application.Match(.cells(i, "DE").value,SEARCHRANGE, 0)) 
            End If
        Next   
    end with
End Sub

重要的是要捕获json异常，以防万一响应字符串无法转换为json对象。然后使用getString（）从创建的json对象获取消息。

如何从POST齐射中读取响应？
