我正在捕获我的屏幕并将该图像转换为字节数组并发送到套接字连接。服务器显示数据但不显示图像。

    StringBuilder sb = new StringBuilder(bytes.length * Byte.SIZE);
    for( int i = 0; i < Byte.SIZE * bytes.length; i++ )

}

注意：- 如果我显示 byte[] 它只包含单个值。

您应该直接将字节缓冲区写入输出流。现在您首先转换为字符串，甚至转换为 utf-8。这没有任何意义，因为图像不能用字符串表示。所以去掉所有的字符串，在 buffer=bos.toByteArray() 输出后写入缓冲区。您不能使用 tempStr。
