android - 登录网站

Question

我正在制作一个需要登录网站的应用程序。为此，我制作了一个 HttpClient 并对 url 执行了一个 HttpPost。据我所知，这是有效的。 StatusCodes 返回 200。在此之后，我对受限制的 url(使用相同的客户端)执行 HttpGet。但是，我总是在我的 LogCat 中返回禁止异常或登录屏幕。通过在网络上搜索，我发现有时需要在 HttpPost 之前先对站点执行 HttpGet，并附加一个 CookieStore。两者都完成了，但仍然没有成功。这里有人可以帮助我吗？

        HttpClient client = new DefaultHttpClient();

        HttpGet initiate = new HttpGet(url);            
        HttpPost post = new HttpPost(url);
        HttpGet page = new HttpGet(restrictedurl);
        HttpContext localContext = new BasicHttpContext();

        CookieStore cookieStore = new BasicCookieStore();
        localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

            try {
                List<NameValuePair> params = new ArrayList<NameValuePair>();
                params.add(new BasicNameValuePair("username", username));
                params.add(new BasicNameValuePair("password", password));

                post.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));

                HttpResponse response = client.execute(initiate, localContext);
                Log.i(Tag, " " + response.getStatusLine().getStatusCode());
                response.getEntity().consumeContent();

                response = client.execute(post, localContext);
                Log.i(Tag, " " + response.getStatusLine().getStatusCode());             
                response.getEntity().consumeContent();                                      

                ResponseHandler<String> handler = new BasicResponseHandler();
                String htmlpage = client.execute(page, handler, localContext);
                Log.i(Tag, " " + response.getStatusLine().getStatusCode());
                Log.i(Tag, htmlpage);
                response.getEntity().consumeContent();  

            } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();

这是我的 LogCat:

Answer 1

禁止错误通常表示您在 Web 服务器上访问的目录/文件存在权限问题。

检查所有者和组权限。还要检查文件上的写入/读取/执行标志。

您能否通过网络浏览器直接导航到 url 并查看它是否也显示禁止消息？
