Android Volley POST-正文中的JSON編碼

Question

我正在使用Volley Android將一些數據發布到Restful Api端點，使用郵差在raw和application/json可以很好地處理身體數據，例如：

{
    "operation": "someaction",
    "key": "pk_test_fssdfsdfjkhkjsdhf84334",
    "token": "tk_test_432332sdxxaJJJJHHHshhsas",
    "ssids":[[{
        "mac":"34:15:13:d4:59:f1" //<--this is important here, it's mac addr
            }]] //<-- yup, with double double [[ ... ]]
}

它可以使用POSTMAN並返回

當我在下面的代碼中使用凌空時，問題開始了：

public void getBleeCardData(Response.Listener<String> response, final String ssidsdata, final ProgressDialog pd)throws JSONException {

    String url = "https://www......com/api/something.do";

    JSONObject jsonBody = new JSONObject();
               jsonBody.put("operation", "something");
               jsonBody.put("key", "pk_try_oqiwFHFKjkj4XMrh");
               jsonBody.put("token", "tk_tkn_erwweelWgH4olfk2");
               jsonBody.put("ssids", ssidsdata.toLowerCase()); 

    final String mRequestBody = jsonBody.toString();

    RequestQueue queue = Volley.newRequestQueue(context);
    StringRequest postRequest = new StringRequest(Request.Method.POST, url,new Response.Listener<String>() {

                @Override
                public void onResponse(String response) {
                    Log.d("Response", response);
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.d("ERROR", "error => " + error.toString());
                }
            }
    ) {
        @Override
        public byte[] getBody() throws AuthFailureError {
            try {
                return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
            } catch (UnsupportedEncodingException uee) {
                VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", mRequestBody, "utf-8");
                return null;
            }
        }

        @Override
        public String getBodyContentType() {
            return "application/x-www-form-urlencoded; charset=UTF-8";
        }
    };
    queue.add(postRequest.setRetryPolicy(new DefaultRetryPolicy(30000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT))); }

我需要編碼方面的幫助，使用Volley像這樣發送數據：

{“ operation”：“ dataMachines”，“ key”：“ pk_test_6pRNAHGGoqiwFHFKjkj4XMrh”，“ token”：“ tk_test_ZQokik736473jklWgH4olfk2”，“ ssids”：“ [[{\\” mac \\“：\\” 34:15:13： ：f1 \\“}]]”}

為什么發送這樣節點"ssids":"[[{\\"mac\\":\\"34:15:13:d4:59:f1\\"}]]"}這樣?,關於什么"\\" ，要刪除一些特殊的編碼嗎？

可以更改編碼來防止那些"\\"嗎？

Answer 1

創建一個JsonObjectRequest

JSONObject jsonBody = new JSONObject();
           jsonBody.put("operation", "something");
           jsonBody.put("key", "pk_try_oqiwFHFKjkj4XMrh");
           jsonBody.put("token", "tk_tkn_erwweelWgH4olfk2");
           jsonBody.put("ssids", ssidsdata.toLowerCase()); 

JsonObjectRequest jobReq = new JsonObjectRequest(Request.Method.POST, url, jsonBody,
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject jsonObject) {
                //Log.d("Responses", jsonObject.toString());
            }
        },
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError volleyError) {
                //Log.e("responses", volleyError.toString());
            }
        });

如果要發送JSONArray，則使用JsonArrayRequest代替JsonObjectRequest

Answer 2

根據android代碼，下面是一個字符串，當您解析一個對象時：

 jsonBody.put("ssids", ssidsdata.toLowerCase()); 

您可以單獨制作ssid，然后將其添加到json主體中，如下所示：

JSONObject ssid= new JSONObject();
ssid.put("mac":"34:15:13:d4:59:f1");
ssid.put("key2","Value2");

將ssid對象添加到您的Json對象中以發送：

    JSONObject jsonBody = new JSONObject();
    jsonBody.put("operation", "something");
     jsonBody.put("key", "pk_try_oqiwFHFKjkj4XMrh");
   jsonBody.put("token", "tk_tkn_erwweelWgH4olfk2");
  jsonBody.put("ssids", ssid); 

在此也進行了說明： 將包含鍵值對的對象作為值傳遞給Java / Android中的哈希圖

Answer 3

JSONObject obmacAdd=new JSONObject();
JSONArray array=new JSONArray();
obmacAdd.put("mac","34:15:13:d4:59:f1");
array.put(obmacAdd.toString());

現在

jsonBody.put("ssids", array.toString());
