Question

我有一个游戏，其服务器在节点js上运行，使用socket io和mysql来存储userdata。问题是我的服务器已经崩溃了两次，它给我的全部内容如下：

Socket io似乎对响应的头部有一些问题，但我该怎么做呢？我还没有尝试任何东西（因为我真的不知道从哪里开始）

Answer 1

我修复了它，这是socket.io中jsonpolling的一个错误，只需用以下命令禁用它：

socket.set('transports', [ 'websocket', 'htmlfile', 'xhr-polling' ])

现在它有效。耶！

奇怪的节点js / socket io崩溃了吗？
