获取Volley成功请求的HTTP状态代码 [英] Get HTTP status code for successful requests with Volley

问题描述

我正在通过截距检索无效网址的内容，即http://www.gigd32fdsu.com: 这是我的测试代码:

I'm retrieving the content of a invalid web address with volley, i.e. http://www.gigd32fdsu.com: This is my test code:

// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
final String url = "http://www.gigd32fdsu.com";

// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, 
new Response.Listener() {
    @Override
    public void onResponse(Object response) {
        // Display the first 500 characters of the response string.
        mTextView.setText("Response is: " + response.toString().substring(0, 500));
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        mTextView.setText("That didn't work! " + error.networkResponse.statusCode);
    }
});
// Add the request to the RequestQueue.
queue.add(stringRequest);

运行此代码时，我从ISP收到带有错误页面的回调onResponse(String).如何读取HTTP状态代码以检测网络显示不正确?

When I run this code I receive the callback onResponse(String) with an error page from my ISP. How can I read the HTTP status code in order to detect that the web displaying is not correct?

谢谢

推荐答案

简单的解决方案是覆盖makeStringReq()中的parseNetworkResponse，而无需其他类:

Simple solution is to override parseNetworkResponse in makeStringReq(), no need for another class:

private void makeStringReq() {
    showProgressDialog();

    StringRequest strReq = new StringRequest(Method.GET,
            Const.URL_STRING_REQ,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    Log.d(TAG, response.toString());
                    msgResponse.setText(response.toString());
                    hideProgressDialog();

                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    VolleyLog.d(TAG, "Error: " + error.getMessage());
                    hideProgressDialog();
                }
            }) {

        @Override
        protected Response<String> parseNetworkResponse(NetworkResponse response) {
            int mStatusCode = response.statusCode;
            return super.parseNetworkResponse(response);
        }
    };

    // Adding request to request queue
    AppController.getInstance().addToRequestQueue(strReq, tag_string_req);

}
