Question

我想使用Volley以下列格式将数据发送到服务器。我怎么能这样做？

[ [＆＃39; CID＆＃39; =＆GT; 1，＆＃39; pid＆＃39; =＆GT; 1，＆＃39;数量＆＃39; =＆GT; 5，＆＃39;摆脱＆＃39; =＆GT; 1，＆＃39; eid＆＃39; =＆GT; 1，＆＃39;做了＃39; =＆GT; 1，＆＃39; takeAt＆＃39; =＆GT; ＆＃39; 2017-07-24 04：03：23＆＃39;]， [＆＃39; CID＆＃39; =＆GT; 1，＆＃39; pid＆＃39; =＆GT; 1，＆＃39;数量＆＃39; =＆GT; 5，＆＃39;摆脱＆＃39; =＆GT; 2，＆＃39; eid＆＃39; =＆GT; 1，＆＃39;做了＃39; =＆GT; 1，＆＃39; takeAt＆＃39; =＆GT; ＆＃39; 2017-07-24 04：03：23＆＃39;]， [＆＃39; CID＆＃39; =＆GT; 1，＆＃39; pid＆＃39; =＆GT; 1，＆＃39;数量＆＃39; =＆GT; 5，＆＃39;摆脱＆＃39; =＆GT; 3，＆＃39; eid＆＃39; =＆GT; 1，＆＃39;做了＃39; =＆GT; 1，＆＃39; takeAt＆＃39; =＆GT; ＆＃39; 2017-07-24 04：03：23＆＃39;] ];

到目前为止，我已经做到了这一点，但它引发了异常

StringRequest stringRequest = new StringRequest(Request.Method.POST, Constant.API_SUBMIT_ORDER, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                Log.e("DATA", "RESPONSE===" + response);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
               error.printStackTrace();
            }
        }) {
            @Override
            protected Map<String, String> getParams() {
                Calendar cal = Calendar.getInstance();
                String time2 = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss a ").format(cal.getTime());
                Map<String, String> orders = new HashMap<>();
                for (int i = 0; i < myProductArrayList.size(); i++) {
                    orders.put("cid", "1");
                    orders.put("skuid", myProductArrayList.get(i).getProductId());
                    orders.put("qty", "50");
                    orders.put("rid", "1");
                    orders.put("eid", "mukulsingh");
                    orders.put("did", "1");
                    orders.put("takenAt", time2);
                }
                return orders;
            }
        };

        stringRequest.setRetryPolicy(new DefaultRetryPolicy(
                MY_SOCKET_TIMEOUT_MS,
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

        RequestQueue requestQueue = Volley.newRequestQueue(this);
        requestQueue.add(stringRequest);

尝试使用这些类

<强> VollyRequests

    public class VollyRequests {

       public void MakeStrRequest(final String Tag, String url, final ArrayList<RequestModel> list, final ResponceLisnter responceLisnter, final String HeaderKey) {
        MyLog.ShowLog("Url", url);

        StringRequest sr = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                try {
                    responceLisnter.getResponce(response, Tag);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                if (error instanceof TimeoutError || error instanceof NoConnectionError) {
                    responceLisnter.getResponceError(VollyError.TIMEOUT_ERROR, Tag);
                } else if (error instanceof AuthFailureError) {
                    responceLisnter.getResponceError(VollyError.AUTH_ERROR, Tag);
                } else if (error instanceof ServerError) {
                    responceLisnter.getResponceError(VollyError.SERVER_ERROR, Tag);
                } else if (error instanceof NetworkError) {
                    responceLisnter.getResponceError(VollyError.NETWORK_ERROR, Tag);
                }
            }
        }) {
            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<String, String>();
                if (list.size() > 0) {
                    for (int i = 0; i < list.size(); i++) {
                        //MyLog.ShowLog(list.get(i).getKey(), list.get(i).getValue());
                        params.put(list.get(i).getKey(), list.get(i).getValue());

                    }
                }
                return params;
            }

            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                Map<String, String> params = new HashMap<String, String>();
                params.put(WebKeys.Headerkey, HeaderKey);
                return params;
            }
        };
        AbcApplication.getInstance().getRequestQueue().add(sr);
        sr.setRetryPolicy(new DefaultRetryPolicy(50000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
    }
}

<强> VollyError

    public class VollyError {
    public static String TIMEOUT_ERROR = "Please try again.";
    public static String NETWORK_ERROR = "Please check your network and try again.";
    public static String SERVER_ERROR = "Please try again.";
    public static String AUTH_ERROR = "Please try again.";
}

<强> RequestModel

    public class RequestModel {

    String Key;
    String Value;

    public ArrayList<JSONObject> getJsonObjects() {
        return jsonObjects;
    }

    public void setJsonObjects(ArrayList<JSONObject> jsonObjects) {
        this.jsonObjects = jsonObjects;
    }

    ArrayList<JSONObject> jsonObjects;

    public RequestModel(String key, String value) {
        this.Key = key;
        this.Value = value;
    }
    public RequestModel(String key, ArrayList<JSONObject> jsonObjects) {
        this.Key = key;
        this.jsonObjects = jsonObjects;
    }

    public String getValue() {
        return Value;
    }

    public void setValue(String value) {
        Value = value;
    }

    public String getKey() {
        return Key;
    }

    public void setKey(String key) {
        Key = key;
    }

}

<强> ResponceLisnter

    public interface ResponceLisnter {

    void getResponce(String str, String Tag) throws JSONException;

    void getResponceError(String errorStr, String Tag);
}

如何拨打凌空班：

public void callingrequest(){
  VollyRequests  vollyRequest =new VollyRequests(); 
 ArrayList<RequestModel> list = new ArrayList<>();
                list.add(new RequestModel(key, value));

vollyRequests.MakeStrRequest(Tag, WebUrl, list, responceLisnter, HeaderKey);
}
   private ResponceLisnter responceLisnter = new ResponceLisnter() {
    @Override
    public void getResponce(final String responce, String Tag) {
       // here is responce
    }

    @Override
    public void getResponceError(String errorStr, String Tag) {
    // here is error
    }
};

申请类

    public class AbcApplication extends Application  {

    //Static value Holders.
    private static AbcApplication mInstance;
    public static Context context;
    private RequestQueue mRequestQueue;
    public static int captureImgCount = 0;

    public static synchronized AbcApplication getInstance() {
        return mInstance;
    }

     @Override
    public void onCreate() {
        super.onCreate();
mInstance = this;

        mRequestQueue = Volley.newRequestQueue(this);}
public RequestQueue getRequestQueue() {
        return mRequestQueue;
    }
