nginx upstream 中带下划线bug,前端会报400错误

白昼怎懂夜的黑 提交于 2019-12-13 04:45:46
有一次偶然的配置,发现nginx 在配置upstream的时候, 如果名字带有下划线,会导致前端返回 400 错误。 百度之后其他人好像也遇到了这个问题: https://blog.csdn.net/horizon_zy/article/details/80139658 为什么会出现这种问题呢? 我们项目有很多的upstream配置,有的也是有下滑线的,为什么他们没有报错,就我们这里报错了。 改完之后(upstream为没有下划线的) 是因为 升级了SpringBoot版本导致了该问题 ,又因为是http的头部变化导致的问题,故可以大胆猜测是因为升级了Tomcat版本导致的该问题。 为什么新版的tomcat为什么出现这个问题? 在SpringBoot项目的issue中搜索了下400问题,发现确实有相关的issue。 https://github.com/spring-projects/spring-boot/issues/13236 虽然看上去跟我们的问题是一样的,都是400问题,但是具体发生的原因是不一样的。这个issue是说,如果domain name .ext 包含数字,比如 “domain.sf1m”,会出现400问题。这个问题也已经在tomcat的新版本中修复了。 带有下划线的Host的http请求,tomcat认为是有问题 那为什么之前版本的tomcat是正常的呢?

How to connect a socket to Genymotion device that is hosting a server?

余生颓废 提交于 2019-12-13 01:12:40
问题 I am currently trying to make a socket connection from my client (iOS simulator) to my host (Genymotion simulator). I am having a hard time finding the correct IP address and configuring the right settings for VirtualBox to get this to work. How can I find the proper IP address and port for iOS to connect to when I host the server on the Genymotion server? 回答1: By default Genymotion devices use a NAT connection to connect to internet. It means they are not visible from your local network. You

Docker container sharing clipboard with host

本小妞迷上赌 提交于 2019-12-12 11:48:20
问题 I searched a bit on google but got no useful results. I'm finishing dockerizing vim and a common problem showed up: its container just won't share the clipboard with the host. I am used to building vim with +clipboard , and to being able to yank text and have it available to the host, or copying text in host and pasting in vim... I thought about making -v volumes that would share this data but I still got nowhere. I'm on Ubuntu 16.10. 回答1: The clipboard is almost certainly part of X, so you

简介 4. 与python交互 4.1. 交互类型 4.2. 增改删 4.3. 查询 4.4. 封装 4.5. 用户登录 与python交互 在熟练使用sql语句的基础上,开始使用python语言提供的模块与mysql进行交互 这是我们在工作中大事要做的事 先学会sql是基础,一定要熟练编写sql语句 安装引入模块 安装mysql模块 sudo apt-get install python-mysql 在文件中引入模块 import Mysqldb Connection对象 用于建立与数据库的连接 创建对象:调用connect()方法 conn=connect(参数列表) 参数host:连接的mysql主机,如果本机是'localhost' 参数port:连接的mysql主机的端口,默认是3306 参数db:数据库的名称 参数user:连接的用户名 参数password:连接的密码 参数charset:通信采用的编码方式,默认是'gb2312',要求与数据库创建时指定的编码一致,否则中文会乱码 对象的方法 close()关闭连接 commit()事务,所以需要提交才会生效 rollback()事务,放弃之前的操作 cursor()返回Cursor对象,用于执行sql语句并获得结果 Cursor对象 执行sql语句 创建对象:调用Connection对象的cursor()方法

Effective methods of indentifying and blacklisting a user

做~自己de王妃 提交于 2019-12-12 04:37:59
问题 I'm currently looking at different ways to use various web/internet technologies in order to be able to identify and blacklist a user of website rather than the host . If that didn't make much sense, let me explain a little: As you might be aware, some sites (particularly forums and message boards) have the unwelcoming visit of spammers every so often. Obviously forum moderators are able to blacklist any accounts used to do this, but it's what occurs after this that's the problem. In many
