虽然非阻塞模式下的connect,一般情况下都是返回-1,但是却忘了检测errno是否为EINPROGRESS,就像这个问题,因为地址写错了,connect返回-1,但是此时的错误却是"Network is unreachable",这种情况下就不能再监听该socket上的写事件,并在回调函数中调用getsockopt了,因为getsockopt得不到错误码,只会返回0。

若该套接字调用了connect,那么接收到的数据报的源地址必须匹配这个已连接地址。 注意,如果一个原始套接字是以0值协议参数创建的,并且没有调用bind,connect,那么该套接字将接收可由内核传递到原始套接字的每个原始数据报的一个副本。 另外,无论何时往一个原始IPv4套接字上递送一个IP数据报,传递到该套接字所在...
由于后端组件的性能限制,在长时间、大批量、连续调用时,有小几率出现Error: connect ECONNREFUSED之类的HTTP报错。此时重新发起请求即可。只要后台工作线程没有崩,这些小问题不会持续影响调用。 图片OCR:Base64 识别 图片OCR:参数查询 二维码:Base64 识别

Qt是一个1991年由Qt Company开发的跨平台C++图形用户界面应用程序开发框架。它既可以开发GUI程序,也可用于开发非GUI程序,比如控制台工具和服务器。Qt是面向对象的框架,使用特殊的代码生成扩展(称为元对象编译器(Meta Object Compiler, moc))以及一些宏,Qt很容易扩展,并且允许真正地组件编程。2008年,Qt Company...
