HttpURLConnection無法讀取全部內容

Question

我正在嘗試閱讀一個網站，但奇怪的是它只返回了一部分。 它僅在該部分的中間結束。

我嘗試使用setChunkedStreamingMode方法，但未進行任何更改。

HttpURLConnection connection = ((HttpURLConnection) new URL(url).openConnection());
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
// I write some data...
String content = readInputStream(connection.getInputStream());

ReadInputStream方法：

private static String readInputStream(InputStream in) throws IOException {
int len = 0;
byte[] buffer = new byte[10000];
ByteArrayOutputStream byteArray = new ByteArrayOutputStream();
while((len = in.read(buffer)) != -1) {
    byteArray.write(buffer,0, len);
}
in.close();

return new String(byteArray.toByteArray());

}

有某種數據限制嗎？

HttpUrlConnection沒有問題，請嘗試以下操作：

StringBuilder stringBuilder = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) { 
       stringBuilder.append(line);
}
inputStream.close();
