想问各位大神什么情况下本机通过127.0.0.1连接会断开

昨晚在电脑上开了一个自己写的server,然后在同一台电脑上开了一个client,通过127.0.0.1连接上了,今早上看的时候客户端与服务器断开连接了,请问什么情况下会断开连接

2个回答

请问是什么连接呢

u011288190
coder_B tcp
大约 4 年之前 回复
u011288190
coder_B tcp
大约 4 年之前 回复

TCP如果长时间没有数据通信,连接会自动断开。

u011288190
coder_B 但是网上有的人回断开,有的人说不会断开
大约 4 年之前 回复

用localhost和127.0.0.1通过php连接mysql均不成功
win10,64位配置了一个apache2.4.17+php7.0.0+mysql5.7.10的环境,改默认端口为8080,测试是否配置成功时编写了两个php代码, 一个用来测试php和apache的文件info.php,用localhost:8080和127.0.0.1:8080均能正常显示信息,如下图 ![图片说明](https://img-ask.csdn.net/upload/201709/03/1504421804_153640.png) 另一个用来测mysql的文件sql.php如下,密码和用户和mysql吻合,但用localhost和127.0.0.1两者均打不开,一直显示正待等待响应,不知道为啥..... <?php $con=mysqli_connect('localhost:8080','root','password'); if(!$con) echo "失败!"; else echo "成功!"; mysqli_close($con); ?> ![图片说明](https://img-ask.csdn.net/upload/201709/03/1504421816_742069.png) 并且,local host和127.0.0.1有时候都能正常打开,有时候只能某一个正常工作,有时候两个都开不了(都是在apache正常工作时).....也不知道为啥.... 求大神解惑~十分感谢! 更多 0

谷歌浏览无法访问localhost,却可以访问127.0.0.1,火狐可以正常访问localhost
前提,WEB开发,需要兼容性测试,所以请勿回复更换浏览器之类的答案。 问题描述: 1、谷歌浏览器无法访问localhost; 2、谷歌浏览器却可以访问127.0.0.1; 3、火狐、IE等其他浏览器均可以正常访问localhost; 4、hosts文件中 127.0.0.1和localhost的对应关系正常; 5、没有使用代理设置; 请大神指点是怎么回事,求教,在线等待,谢谢~

在一个数组中首先判断里的自符是否为回文字符,如果是在按其长度排序,若相同长度的则按ASCII码排序(用c++)求大神解救.......
请教一下,为什么本地开启jekyll s 浏览页面127.0.0.1:4000页面非常慢?
启动jekyll s后,输入127.0.0.1:4000,打开页面非常慢,请问一下大神,这是因为博客中 插件太多的缘故吗,开启的博客有评论插件、down下拉单插件,云标签插件等等,是不是这个原因呢? 我打开一个插件很少的博客,很快。
流光的问题,连接被远程主机关闭.

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
