项目需要，在mac上将打包好的文件(四五百兆)自动上传到web后台，用了两种方式上传，都报了类似的错误，在windows和linux上测试不会报错，但是到了mac打包机上就会报错：

①第一种报错：

Traceback (most recent call last):

搜索能力有限，去谷歌搜了下没有找到合适的解决办法，或者是理解不够：

你这个一般都需要结合服务器端的软件代码、框架版本之类的来解决啊，不过既然你特意说了Windows、Linux和MAC的差异，我只知道一个比较重要的差异，就是MAC操作系统在对方shutdown的情况下不能保持半连接状态，一段时间后悔自动关闭，所以如果你的服务器端在还没有传输完文件的情况下就以某种方式SHUTDOWN了写的一端，就会在传输中出错，比如说先发送了返回值，再慢慢接收数据。没有别的信息的话只能先这么猜了。
