HttpServletRequest getRemoteAddr() not working how I would expect

阅读更多关于 HttpServletRequest getRemoteAddr() not working how I would expect

问题 The following code is returning incorrectly, from what I understand: HttpServletRequest httpRequest = (HttpServletRequest) request; String userIPAddress = httpRequest.getRemoteAddr(); // Actual // "0:0:0:0:0:0:0:1%0" // Expected // "0:0:0:0:0:0:0:1" Any idea why the %0 is there? When I loop through InetAddress.getAllByName("localhost") I get the following: // ["192.168.100.1", "127.0.0.1", "0:0:0:0:0:0:1"] How would I test for localhost if getRemoteAddr() is returning invalid format, or am I

问题 Right now I get a blank page when localhost runs, but the deployed app is fine. The logs show the "database is locked". How do I "unlock" the database for localhost? 回答1: This can happen if you're running multiple instances of dev_appserver without giving them distinct datastore files/directories. If you need to be running multiple instances, see dev_appserver.py --help and look at the options for specifying paths/files. 回答2: Dave W. Smith has the right idea. I had this same issue and looking

问题 I have a PHP script where I'd like to detect if the user is running on a local machine, not accessible over the Internet. Currently I check for the server address to he 127.0.0.1. Is this the best practice or is there a better way? 回答1: Localhost always translates to the loopback IP address 127.0.0.1 in IPv4, or ::1 in IPv6, So validating the IP Within your application would be secure, if you mean if(IPAddress::In(array("127.0.0.1","::1"))) { //Show Application } I Very much doubt that you

localhost Won't Immediately Update

阅读更多关于 localhost Won't Immediately Update

问题 I have been using XAMPP to connect to localhost to do editing on my computer for websites. I have been using it for over a year now and in the past whenever I would update the local file, I could refresh the page on my browser and it would immediately update. Now, I can't get it to update even if, for example, an image file has changed. I'm wondering if it's an issue with cookies (which I haven't had in the past). Is there a common reason that this happens? I couldn't find anything upon a

Why doesn't http://localhost/ load anything with WAMP?

阅读更多关于 Why doesn't http://localhost/ load anything with WAMP?

问题 I recently tried installing WAMP but found that none of the pages will load. It also has an orange W logo, if that means anything. It does say (Tray Icon) that the WAMPserver is online though. I also did some research and found that Skype may cause problems and I removed the Use port 80 and 443 as alternatives for incoming connections option, but it still won't work. I get the following screen in my Chrome browser, any ideas? EDIT: After further research I found that something may have gone

1、连接Mysql 格式： mysql -h主机地址 -u用户名－p用户密码 1、连接到本机上的MYSQL。首先打开DOS窗口，然后进入目录mysql\bin，再键入命令mysql -u root -p，回车后提示你输密码.注意用户名前可以有空格也可以没有空格，但是密码前必须没有空格，否则让你重新输入密码。如果刚安装好MYSQL，超级用户root是没有密码的，故直接回车即可进入到MYSQL中了，MYSQL的提示符是： mysql> 2、连接到远程主机上的MYSQL。假设远程主机的IP为：110.110.110.110，用户名为root,密码为abcd123。则键入以下命令： mysql -h110.110.110.110 -u root -p 123;（注:u与root之间可以不用加空格，其它也一样） 3、退出MYSQL命令： exit （回车） 2、修改密码格式：mysqladmin -u用户名 -p旧密码 password 新密码 1、给root加个密码ab12。首先在DOS下进入目录mysql\bin，然后键入以下命令 mysqladmin -u root -password ab12 注：因为开始时root没有密码，所以-p旧密码一项就可以省略了。 2、再将root的密码改为djg345。 mysqladmin -u root -p ab12 password

1.创建用户: CREATE USER 'username'@'host' IDENTIFIED BY 'password'; host为localhost时，表示可本地登录；使用通配符%时，表示可以从任意远程主机登陆。 2.限制用户权限： GRANT SELECT, INSERT, UPDATE, REFERENCES, DELETE, CREATE, DROP, ALTER, INDEX, CREATE VIEW, SHOW VIEW ON `db_test`.* TO 'user_test'@'localhost'; ‘db_test’为指定的数据库，’user_test’是限制的用户， ’localhost’表示只能本地访问，如果想让远程IP访问，可将’localhost’换成’%’ 注意：单个单个数据库的所有权限，分配给指定用户的方法： GRANT ALL PRIVILEGES ON `zkdata`.* TO 'zkuser'@'%' WITH GRANT OPTION 3. 刷新权限： flush privileges; 注意：Navicat需要重新打开连接，才能起作用。来源： CSDN 作者：上线就吃代码链接： https://blog.csdn.net/p445726392/article/details/103628504
