Examples of org.apache.http.HttpEntity.writeTo()

org.apache.http.HttpEntity.writeTo()
Writes the entity content to the output stream. @param outstream the output stream to write entity content to @throws IOException if an I/O error occurs

        throws IOException {
      super(target, request);
      HttpEntity entity = request.getEntity();
      // TODO 暂时把所有的请求先读入内存，在存在大文件的时候可能OutOfMemory,以后重写一个基于MultiPartInputStream来优化
      ByteArrayOutputStream byteOutStream = new ByteArrayOutputStream();
      entity.writeTo(byteOutStream);
      httpInStream = new ByteArrayInputStream(
          byteOutStream.toByteArray());


      byteOutStream.close();
      contentLength = entity.getContentLength();
