Question

在我的Android应用程序中，我有一个StringRequest并使用Volley发送它。问题是onResponse和onErrorResponse都没有被调用!!我在我的应用程序的其他部分使用JSONRequest，我完全没有问题。我错过了什么？

Here is one of the samples I tried

这让我困扰了几个小时，我不知道是什么导致了这一点。任何线索都高度赞赏。

以下是代码：

public class AccountManagerProxy  {
StringRequest req;

public void run() {
    try {
        String s1 = URLEncoder.encode("user", "UTF-8");
        String s2 = URLEncoder.encode("pass", "UTF-8");
        String uri = String.format("http://****/token?grant_type=password&username=%1$s&password=%2$s", s1, s2);
        req = new StringRequest(Request.Method.GET, uri, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                VolleyLog.v("Response:%n %s", response);
                Log.d("##", "##");
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.e("Error: ", error.getMessage());
                Log.d("@@", "@@");
            }
        }) {
            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
                Map<String, String> params = new HashMap<String, String>();
                params.put("Content-Type", "application/x-www-form-urlencoded");
                return params;
            }
            @Override
            protected Response<String> parseNetworkResponse(NetworkResponse response) {
                String parsed;
                try {
                    parsed = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
                } catch (UnsupportedEncodingException e) {
                    parsed = new String(response.data);
                }
                return Response.success(parsed, HttpHeaderParser.parseCacheHeaders(response));
            }
        }
        ;

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } Singleton.getInstance().getRequestQueue().add(req);
}

}
