大佬教程收集整理的这篇文章主要介绍了android – Volley库忽略format = feed&type = rss Params，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我需要使用Volley库获取 RSS Feed但是Volley一直忽略我的格式= Feed& type = RSS Params.
我尝试了所有的东西,但我无法让它工作.
这是我的网址：http：//almesryoon.com/دفتر-أحوال-الوطن？format = Feed& type = RSS
注意：此网址适用于Google PostMan
我的SimpleXmlrequest类：

public class SimpleXmlrequest<T> extends request<T> {

    private static final serializer serializer = new Persister();
    private final Class<T> clazz;
    private final Map<String,String> headers;
    private final Listener<T> listener;


    /**
     * Make http request and return a parsed object from Response
     * Invokes the other constructor.
     *
     * @see SimpleXmlrequest#SimpleXmlrequest(int,String,Class,Map,Listener,ErrorListener)
     */
    public SimpleXmlrequest(int method,String url,Class<T> clazz,Listener<T> listener,ErrorListener errorListener) {
        this(method,url,clazz,null,listener,errorListener);
    }


    /**
     * Make http request and return a parsed object from XML Response
     *
     * @param url URL of the request to make
     * @param clazz Relevant class object
     * @param headers Map of request headers
     * @param listener
     * @param errorListener
     *
     */
    public SimpleXmlrequest(int method,Map<String,String> headers,ErrorListener errorListener) {
        super(method,errorListener);
        this.clazz = clazz;
        this.headers = headers;
        this.listener = listener;
    }


    @Override
    public Map<String,String> getHeaders() throws AuthFailureError {
        return headers != null ? headers : super.getHeaders();
    }


    @Override
    protected void deliverResponse(T responsE) {
        listener.onResponse(responsE);
    }

    @Override
    public String getBodyContentType() {
        return "application/xml";
    }

    @Override
    protected Response<T> parseNetworkResponse(NetworkResponse responsE)
    {
        try {

            String data = new String(response.data,httpHeaderParser.parseCharset(response.headers));// The problem here this data is not XML

            return Response.success(serializer.read(clazz,data),httpHeaderParser.parseCacheHeaders(responsE));
        }
        catch (UnsupportedEncodingException E) {
            return Response.error(new ParseError(E));
        }
        catch (Exception E) {
            return Response.error(new VolleyError(e.getmessage()));
        }
    }
}

此外,我试图使用METHOD.POST与getParams()方法

我正在使用此代码并且它工作正常,但现在不推荐使用httpParams,BasichttpParams,httpconnectionParams,DefaulthttpClient,httpGet,httpResponse和httpentity.
我的工作代码：

StringBuilder chaine = new StringBuilder("");

        try {

            httpParams httpParameters = new BasichttpParams();
            // Set the timeout in milliseconds until a connection is established.
            // The default value is zero,that means the timeout is not used.
            int timeoutConnection = AppConstants.CONNECTION_TIMEOUT_SEC * 1000;
            httpconnectionParams.setConnectionTimeout(httpParameters,timeoutConnection);
            // Set the default socket timeout (SO_TIMEOUT)
            // in milliseconds which is the timeout for waiTing for data.
            int timeoutSocket = AppConstants.soCKET_TIMEOUT_SEC * 1000;
            httpconnectionParams.setSoTimeout(httpParameters,timeoutSocket);

            // request method is GET
            DefaulthttpClient httpClient = new DefaulthttpClient(httpParameters);
            httpGet httpGet = new httpGet(url);

            httpResponse httpResponse = httpClient.execute(httpGet);
            httpentity httpentity = httpResponse.getEntity();

            InputStream inputStream = httpentity.getContent();

            BufferedReader rd = new BufferedReader(new InputStreamReader(inputStream));

            String line;

            while ((line = rd.readLine()) != null) {

                chaine.append(linE);

            }

            rd.close();

        } catch (IOException E) {
            // wriTing exception to log
            e.printStackTrace();
        }

在使用您的服务器URL测试一些示例代码后,我发现它得到了301响应.从您的第一个网址,第二个网址将是(https)

https://almesryoon.com/%D8%AF%D9%81%D8%AA%D8%B1-%D8%A3%D8%AD%D9%88%D8%A7%D9%84-%D8%A7%D9%84%D9%88%D8%B7%D9%86?format=Feed&type=RSS

第三个网址将是：

http://m.almesryoon.com/%d8%af%d9%81%d8%aa%d8%b1-%d8%a3%d8%ad%d9%88%d8%a7%d9%84-%d8%a7%d9%84%d9%88%d8%b7%d9%86?template=mobile

最后的网址是(https)：

https://m.almesryoon.com/%d8%af%d9%81%d8%aa%d8%b1-%d8%a3%d8%ad%d9%88%d8%a7%d9%84-%d8%a7%d9%84%d9%88%d8%b7%d9%86?template=mobile

使用此最终URL和下面的示例代码,您将获得200个响应代码.我想你可以用我上面提到的最终网址尝试你的代码.

requestQueue queue = Volley.newrequestQueue(this);
String url = "https://m.almesryoon.com/%d8%af%d9%81%d8%aa%d8%b1-%d8%a3%d8%ad%d9%88%d8%a7%d9%84-%d8%a7%d9%84%d9%88%d8%b7%d9%86?template=mobile";
Stringrequest request = new Stringrequest(url,new Response.Listener<String>() {
    @Override
    public void onResponse(String responsE) {
        Log.i("onResponse",responsE);
    }
},new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Log.e("onErrorResponse",error.toString());
    }
});

queue.add(request);
