如何通过 HttpGet 从 android 本地网络中的 pc 获取文件

Question

我在我的电脑上运行了 c# 程序来监听 http 请求，我尝试制作一个应用程序，它通过 HttpGet 从我的电脑获取文件。

new HttpGet(url + 文件路径);

文件在同一目录下，路径为C://Users/abc/def/test.txt

但如果我将它写入文件路径，我将无法获取该文件。我应该写什么到文件路径？

提前致谢

您需要创建一个 AsyncTask 来执行您的请求，因为从 Android Honeycomb 开始，您无法在主线程上添加网络请求。

这是一个例子：

private class HttpGetter extends AsyncTask<URL, Void, Void> {

                @Override
                protected Void doInBackground(URL... urls) {
                        // TODO Auto-generated method stub
                        StringBuilder builder = new StringBuilder();
                        HttpClient client = new DefaultHttpClient();
                        HttpGet httpGet = new HttpGet(urls[0]);

                        try {
                                HttpResponse response = client.execute(httpGet);
                                StatusLine statusLine = response.getStatusLine();
                                int statusCode = statusLine.getStatusCode();
                                if (statusCode == 200) {
                                        HttpEntity entity = response.getEntity();
                                        InputStream content = entity.getContent();
                                        BufferedReader reader = new BufferedReader(
                                                        new InputStreamReader(content));
                                        String line;
                                        while ((line = reader.readLine()) != null) {
                                                builder.append(line);
                                        }
                                        Log.v("Getter", "Your data: " + builder.toString()); //response data
                                } else {
                                        Log.e("Getter", "Failed to download file");
                                }
                        } catch (ClientProtocolException e) {
                                e.printStackTrace();
                        } catch (IOException e) {
                                e.printStackTrace();
                        }

                        return null;
                }
    }

HttpGetter get = new HttpGetter();
get.execute("http://192.168.1.2/song.mp3");
