Question

我的应用有问题。我设法得到一个html＆＃34; GET＆＃34;没有问题的回应，但当我尝试＆＃34; POST＆＃34;它得到java.io.IOException：Connection上意外的流结束 GET和POST代码在同一个活动中，GET在onCreate（）中，POST在按钮点击。

似乎每次它都试图获取有关responecode，responsemessage，getInputStream等的信息......

我的代码：

private class PostClass2 extends AsyncTask<String, Void, Void> {
    private final Context context;
    public PostClass2(Context c){
        this.context = c;
    }
    @Override
    protected Void doInBackground(String... params) {
    try {
        URL url = new URL("http://speedport.ip/data/InternetConnectionS1P1.json");
        HttpURLConnection connection2 = (HttpURLConnection) url.openConnection();
        String urlParameters = "t_password="+t_passwordout+"&other_name="+providerout+"&other_user="+usernameout+"&other_password="+passout+"&showpw="+showpwin+"&always_online=1&idle_time=2";
        connection2.setRequestMethod("POST");

        connection2.setRequestProperty("ACCEPT-LANGUAGE", "hu-HU,hu;q=0.8,en-US;q=0.6,en;q=0.4");
        connection2.setRequestProperty("Cookie", cookietoheader);
        connection2.setDoOutput(true);
        DataOutputStream dStream = new DataOutputStream(connection2.getOutputStream());
        dStream.writeBytes(urlParameters);
        dStream.flush();
        dStream.close();
        System.out.println("\nSending 'POST' request to URL : " + url);
        System.out.println("Params: "+urlParameters);
        final StringBuilder output = new StringBuilder("Request URL " + url);
        output.append(System.getProperty("line.separator") + "Type " + "GET");
        output.append(System.getProperty("line.separator") + "Cookie " + cookietoheader);
        BufferedReader br = new BufferedReader(new InputStreamReader(connection2.getInputStream()));
        String line = "";
        StringBuilder responseOutput = new StringBuilder();
        System.out.println("output===============" + br);
        while ((line = br.readLine()) != null) {
            responseOutput.append(line);
        }
        br.close();
        output.append(System.getProperty("line.separator") + "Response " + System.getProperty("line.separator") + System.getProperty("line.separator") + responseOutput.toString());
        outtotext2 = responseOutput.toString();
        } catch (MalformedURLException e) {
            e.printStackTrace();

        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
    protected void onPostExecute(Void ignored) {
        t.setText(textout1);
    }
}
