 ### 关键代码
 网络请求`Volley+Gson`
 ```java
-private void query() {
-    GsonRequest<QueryResult> request = new GsonRequest<QueryResult>(Utils.getQueryUrl(mExpressInfo),
-            QueryResult.class, new Listener<QueryResult>() {
+private void search() {
+    GsonRequest<SearchResult> request = new GsonRequest<SearchResult>(Utils.formatSearchUrl(mSearchInfo),
+            SearchResult.class, new Response.Listener<SearchResult>() {
         @Override
-        public void onResponse(QueryResult queryResult) {
-            Log.i("Query", queryResult.getMessage());
-            if (queryResult.getStatus().equals("200")) {
-                onQuerySuccess(queryResult);
-            } else {
-                onQueryFailure(queryResult);
-            }
+        public void onResponse(SearchResult searchResult) {
+            Log.i(TAG, searchResult.getMessage());
+            onSearch(searchResult);
         }
-    }, new ErrorListener() {
+    }, new Response.ErrorListener() {
         @Override
         public void onErrorResponse(VolleyError volleyError) {
-            Log.e("Query", volleyError.getMessage(), volleyError);
+            Log.e(TAG, volleyError.getMessage(), volleyError);

             return headers;
