Question

我最近在java中编写了一些代码，该代码应该将字符串发送到php脚本，它的工作原理非常好。但是当我在android程序中使用它时它拒绝工作。以为有人可以帮我找出问题所在！

public static String main(String x, String y){
    if (android.os.Build.VERSION.SDK_INT > 9)
    {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

    }else{

        try{

            String username = x;
            String password = y;

            URL url = new URL(login_url);
            HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
            httpURLConnection.setRequestMethod("POST");
            httpURLConnection.setDoInput(true);
            httpURLConnection.setDoOutput(true);

            OutputStream outputStream = httpURLConnection.getOutputStream();
            BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));

            String post_data = URLEncoder.encode("username","UTF-8")+"="+URLEncoder.encode(username,"UTF-8")+"&"
                    +URLEncoder.encode("password","UTF-8")+"="+URLEncoder.encode(password,"UTF-8");

            bufferedWriter.write(post_data);
            bufferedWriter.flush();
            bufferedWriter.close();
            outputStream.close();

            // LÄSER FRÅN HEMSIDAN

            InputStream inputStream = httpURLConnection.getInputStream();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream,"iso-8859-1"));
            String result="";
            String line="";
            while((line = bufferedReader.readLine()) != null){

                result += line;
            }



            //AVSLUTA CONNECTION
            bufferedReader.close();
            inputStream.close();
            httpURLConnection.disconnect();

            return result;

        }catch(Exception e){
            e.printStackTrace();
        }
    }



    return null;

}

我确实通过添加

允许清单中的互联网权限

    <uses-permission android:name="android.permission.INTERNET" />

但它根本没有给我任何结果。起初我认为也许在PHP脚本中有一些东西丢失了，但是在eclipse中测试它时工作得非常好，所以android部分肯定会出现错误或缺失，对吧？

确保您的else块执行。

这是一个非常糟糕的做法 - 使用Retrofit库来代替使用REST apis。 http://www.vogella.com/tutorials/Retrofit/article.html

Android html POST无法正常工作，没有给出错误
