Android的HttpURLConnection，只加载第一个4066符号，并中断请求

Question

问题是我没有得到一个完整的结果。只有一部分，那不是销售的一部分，和前4066个字符。问题是一样的，IOException似乎不是由

引起的。

private class GetContent extends AsyncTask<Void, Void, String>{
    HttpURLConnection urlConnection = null;
    BufferedReader reader = null;
    String resultJson = "";
    @Override
    protected String doInBackground(Void... params) {
        try{
            URL url = new URL("http://www.json-generator.com/api/json/get/bSFiRdwiSq?indent=2");
            urlConnection = (HttpURLConnection)url.openConnection();
            urlConnection.setRequestMethod("GET");
            urlConnection.connect();
            InputStream inputStream = urlConnection.getInputStream();
            StringBuffer buffer = new StringBuffer();
            reader = new BufferedReader(new InputStreamReader(inputStream));
            String line;
            while ((line = reader.readLine()) != null){
                buffer.append(line);
            }
            resultJson = buffer.toString();
            Log.d("Result:", resultJson);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
}`

结果

Answer 1

您需要在代码中实现以下几点:

1. urlConnection.connect ();当我们调用urlConnection.getInputStream()时，不重要;然后自动调用Url

2. 关闭你打开的所有流

所以代码是

private class GetContent extends AsyncTask<Void, Void, String>{
HttpURLConnection urlConnection = null;
BufferedReader reader = null;
String resultJson = "";
@Override
protected String doInBackground(Void... params) {
    try{
        URL url = new URL("http://www.json-generator.com/api/json/get/bSFiRdwiSq?indent=2");
        urlConnection = (HttpURLConnection)url.openConnection();
        urlConnection.setRequestMethod("GET");
        InputStream inputStream = urlConnection.getInputStream();
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream,"UTF-8"));
        StringBuilder builder = new StringBuilder();
        int line;
        while ((line=reader.read()) > 0){
            builder.append((char)line);
        }
        reader.close();
        inputStream.close();
        String resultJson = builder.toString();
        Log.d("Result:", resultJson);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}
}

Answer 2

你的读逻辑应该是这样的:

InputStream in = mConnection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in, enconding));    
int ch;
StringBuilder sb = new StringBuilder();         
while ((ch=reader.read()) > 0) {            
    sb.append((char)ch);
}
String resultjson= sb.toString().trim();
Log.d("Result:", resultJson);
