Question

我有一个symfony webservice，将数据库表的内容作为json返回。

此代码直接来自Android HttpUrlConnection tutorials本身。

从Web浏览器调用时，它可以通过json检查工具验证
没有转义字符或\ n任何地方
缓冲区在1190个字符后被切断
更短的json响应能够完美地工作

org.json.JSONException：在...的字符50000处的未终止字符串{我的jason继续一段时间并被terminated终止我假设的代表空char []部分

这是它出错的地方，读者没有正确填充缓冲区

// Reads an InputStream and converts it to a String.
public String readIt(InputStream stream, int len) throws IOException {
    Reader reader = new InputStreamReader(stream, "UTF-8");
    char[] buffer = new char[len];
    reader.read(buffer);
    return new String(buffer);
}

HttpUrlConnection调用代码：

 /*
Given a URL, establishes an HttpUrlConnection and retrieves
the web page content as a InputStream, which it returns as
a string.
*/
private String downloadUrl(String myurl) throws IOException {
    InputStream inputStream = null;
    /*
    Only display the first 500 characters of the retrieved
    web page content.
    */
    int len = 5000;
    String result = "[]";

    try {
        System.out.print("TRYING TO OPEN: " + myurl + "\n");
        URL url = new URL(myurl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setReadTimeout(30000 /* milliseconds */);
        connection.setConnectTimeout(30000 /* milliseconds */);
        connection.setRequestMethod("POST");
        connection.setDoInput(true);
        // Starts the query
        connection.connect();
        int response = connection.getResponseCode();
        Log.d("HTTP CONNECTION :", "The response is: " + response);
        inputStream = connection.getInputStream();

        // Convert the InputStream into a string
        result = readIt(inputStream, len);

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (inputStream != null) {
            inputStream.close();
        }
    }
    return result;
}

我遇到的大多数其他SO答案都提到现在已弃用的代码，感谢您阅读。

Android接收json，缓冲区未正确填充
