我正在使用链接使用HttpsURLConnection在大块文件中执行https帖子 -

file upload using httppost android

我得到致命异常 -

HPROF分析 -

泄漏嫌疑人

" libcore.net.http.RetryableOutputStream"的一个实例;加载""占用134,216,008(82.46%)字节。存储器在" byte []"的一个实例中累积。由""。

加载

详情

buf java.io.ByteArrayOutputStream @ 0x444fd460 16 134,215,984

content libcore.net.http.RetryableOutputStream @ 0x444fd448 24 134,216,008

out java.io.DataOutputStream @ 0x4467f918 24 48

有人可以帮我摆脱这个。

我也添加了DataOutputStream.flush,但没有用

    // read file and write to buffer
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

    int pktSend = 0;
    // continue till bytes read not null
    while (bytesRead > 0) {
        dos.write(buffer, 0, bufferSize);
        bytesAvailable = fileInputStream.available();
        bufferSize = Math.min(bytesAvailable, maxBufferSize);
        bytesRead = fileInputStream.read(buffer, 0, bufferSize);
        pktSend++;
        dos.flush();
    }

答案 0 :(得分:0)

也许您可以在代码上尝试以下设置:

        // set the request mode as POST
        urlConnection.setRequestMethod("POST");

        // disable using cache.
        urlConnection.setUseCaches(false);

        // enable Output/Input.
        urlConnection.setDoOutput(true);
        urlConnection.setDoInput(true);
