Question

我正在使用Volley Android将一些数据发布到Restful Api端点，使用邮递员它可以在raw和application/json中运行很好的正文数据，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 [[ ... ]]
}

它使用POSTMAN并返回

当我在下面的代码中使用截击时，问题就开始了：

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))); }

我需要编码方面的帮助，使用Volley发送的数据如下：

{ “操作”： “dataMachines”， “关键”： “pk_test_6pRNAHGGoqiwFHFKjkj4XMrh”， “标记”： “tk_test_ZQokik736473jklWgH4olfk2”， “的SSID”： “[[{\” MAC \ “：\” 34:15:13： D4：59：F1 \ “}]]”}

为什么像"ssids":"[[{\"mac\":\"34:15:13:d4:59:f1\"}]]"}这样发送此节点？如何"\"，删除它的某些特殊编码？

是否可以更改编码以阻止"\"？

Answer 1

创建一个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());
            }
        });

如果您要发送JSONArray，则使用JsonArrayRequest而不是JsonObjectRequest

Answer 2

根据android代码，在解析对象时，下面需要一个字符串：

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

你可以单独制作ssid然后将它添加到json体中，如下所示：

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

将ssid对象添加到Json对象中以发送：

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

在此解释：Pass an object containing key value pairs, as a value to a hashmap in Java/Android

Answer 3

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

现在

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