Android沒有讀取完整的HttpURLConnection InputStream內容

Question

我已經在Java應用程序類進行了測試下面的代碼和它的作品 ，它調用我的后端的Java servlet和讀取二進制字節到字節[]

private byte[] readResponse(HttpURLConnection connection) throws IOException {
    InputStream inputStream = connection.getInputStream();
    BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
    int contentLength = connection.getContentLength();
    byte[] buffer;
    if (contentLength>-1) {
        buffer = new byte[contentLength];
        int readCount = bufferedInputStream.read(buffer, 0 , contentLength);
        System.out.println("Content Length is " + contentLength + " Read Count is " + readCount);
    }
    return buffer;
}

現在我將這個Java代碼移動到我的Android代碼中，並且它以某種方式僅部分讀取內容，服務器發送大約5709個字節，Android應用程序僅讀取1448個字節

有趣的是，如果我進入調試模式並將斷點放在一線

int readCount = bufferedInputStream.read(buffer, 0 , contentLength);

並逐步調試，變量

readCount

可以達到5709個字節。 如果我沒有設置斷點，則變為1448字節。 為什么？

看起來有些延時問題？

謝謝。 問候，

Answer 1

這對我有用：

    // Read response
    //int responseCode = connection.getResponseCode();
    StringBuilder response = new StringBuilder();
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    String line;
    while ((line = reader.readLine()) != null) {
           response.append(line);
    }

    reader.close();
    response.toString();

感謝大家的幫助，特別是用戶greenapps的回答。 我將加載過程分解為1kb緩沖區並解決了問題。 以下是代碼：

private byte[] readResponse(HttpURLConnection connection) throws IOException {
    InputStream inputStream = connection.getInputStream();
    int contentLength = connection.getContentLength();
    byte[] buffer;
    buffer = new byte[contentLength];
    int bufferSize = 1024;
    int bytesRemaining = contentLength;
    int loadedBytes;
    for (int i = 0; i < contentLength; i = i + loadedBytes) {
        int readCount =   bytesRemaining > bufferSize ? bufferSize : bytesRemaining;
        loadedBytes = inputStream.read(buffer, i , readCount);
        bytesRemaining = bytesRemaining - loadedBytes;
    }
    return buffer;
}
