我使用一个
然而，当我尝试将我的
OkHttpClient 从服务器上下载一个数据库并将其复制到我的Android应用程序中，请求很好，我得到了正确的内容。然而，当我尝试将我的
byteStream 写入文件时，我会收到一个 java.IOException.closed 的错误。你知道我做错了什么吗？Response httpResponse = webApiClient.execute(
new WebApiRequest(WebApiMethod.DB_DOWNLOAD), context);
if (httpResponse.code() == 200)
{
try
{
InputStream inputStream = httpResponse.body().byteStream();
File databasePath = context.getDatabasePath(Constant.DATABASE_NAME);
FileOutputStream output = new FileOutputStream(databasePath);
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int len;
while ((len = inputStream.read(buffer)) != -1)
{
output.write(buffer, 0, len);
}
success = true;
}
catch (Exception exc)
{
Utils.DisplayException(exc, context);
}
}
我也尝试使用 BufferedSink 读取我的 ByteStream，但结果仍然相同。
BufferedSink sink = Okio.buffer(Okio.sink(databasePath));
sink.writeAll(httpResponse.body().source());
sink.close();
