Volley在与spring mvc架构的服务器交互时需要注意的坑

/**
* 自定义Volley解决post请求在spring mvc服务端的问题
*/
public class MyVolleyCallBack extends Request<JSONObject> {
private Map<String, String> mMap;
private Response.Listener<JSONObject> mListener;

public MyVolleyCallBack(String url, Response.Listener<JSONObject> listener, Response.ErrorListener errorListener, Map<String, String> map) {
super(Request.Method.POST, url, errorListener);

mListener = listener;
mMap = map;
}

/**
* mMap是已经按照前面的方式,设置了参数的实例
*/
@Override
protected Map<String, String> getParams() throws AuthFailureError {
return mMap;
}

/**
* 此处因为response返回值需要json数据,和JsonObjectRequest类一样即可
*/
@Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
try {
String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));

return Response.success(new JSONObject(jsonString), HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));
}
}

@Override
protected void deliverResponse(JSONObject response) {
mListener.onResponse(response);
}
}
