Get PID of browser started by Selenium (in java)

阅读更多关于 Get PID of browser started by Selenium (in java)

问题 Is it possible to get the PID of the browser that is started by Selenium Webdriver. This would have to be in Java, as that is how I run webdriver. Is that possible? 回答1: Not particularly, you would have get the list of processes currently running and filter it down. There is no special attributes or features that Selenium uses to launch a browser. Therefore, if you are running an instance of that browser that was launched manually , you will get that too. That is to say that if you have two

阅读更多关于 Java, windows: Get process name of given PID

问题 Running on windows. I need to know from within my program which processes (like Skype) are running on port :80 . I should be able to get the PID of the process running on port :80 via netstat -o -n -a | findstr 0.0:80 . What would be the best way to get the name of a process with a given PID from within Java? If there is any way to get the name of the process running on port :80 from within Java I would prefere that also. The reason I need this is that my application launches a jetty web

问题 I am trying to kill a process by name which i will pass as a variable to a system command. Below is what i have: my $processName=$ARGV[0]; print "$processName\n"; system(q/kill -9 `ps -ef | grep '$processName' | grep -v grep | awk '{print $2}'`/); The above script throws an error: kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] However, if i directly enter the process name inside the system command, it works. Can someone help me on this? 回答1: One

Redirecting standard output to a file containing the pid of the logging process

问题 I've searched for a while but i can't either find an answer or come up with a solution of my own, so I turn to you guys. First question I actually ask here :) I would like to run several instances of the same program, and redirect each of these programs' standard output to a file that contains that same process' pid, something like: my_program > <pid of the instance of my_program that is called in this command>.log I'm aware that this is not even close of the way to go :P I have tinkered

Pass handle down pipeline

阅读更多关于 Pass handle down pipeline

问题 Say I have node foo.js | node bar.js is there a way to pass a handle on foo's stdin to bar.js? I have a rare case where I'd like to communicate backwards in the pipeline. At the least I know that I could send node bar.js the pid of node foo.js . Given that pid, on *nix, I should be able to write to foo's stdin using: /proc/<pid>/fd/0 but is there a way to do the same on MacOS? 回答1: So there are different ways of doing it. Approach 1 - IOCTL This is inspired from https://stackoverflow.com/a

Restarting nginx: nginxnginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

阅读更多关于 Restarting nginx: nginxnginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

问题 When I try to restart nginx with sudo /etc/init.d/nginx restart I get the message from the subject. I discovered that the reason is most likely that the script doesn't know how to stop the deamon because the pid file (/var/run/nginx.pid) is not created on start. I have two installations on two different servers... one was compiled from source and the other came with phusion passenger. I tried this command: start-stop-daemon --start --quiet --pidfile /var/run/nginx.pid --exec /usr/sbin/nginx -

问题 Just got confused with parent pid value in child process block. My program is given below: int main(int argc, char *argv[]) { pid_t pid; pid=fork(); if(pid==-1){ perror("fork failure"); exit(EXIT_FAILURE); } else if(pid==0){ printf("pid in child=%d and parent=%d\n",getpid(),getppid()); } else{ printf("pid in parent=%d and childid=%d\n",getpid(),pid); } exit(EXIT_SUCCESS); } Output: pid in parent=2642 and childid=2643 pid in child=2643 and parent=1 In "Advanced Unix programming" it says that

App开放接口api安全性的设计与实现 Posted on 2016-09-29 11:49 琪齐阅读(4121) 评论(0) 编辑收藏阅读目录导航公告 App开放接口api安全性的设计与实现前言设计　　1、原理　　2、具体实现代码实现回到目录前言在app开放接口api的设计中，避免不了的就是安全性问题，因为大多数接口涉及到用户的个人信息以及一些敏感的数据，所以对这些接口需要进行身份的认证，那么这就需要用户提供一些信息，比如用户名密码等，但是为了安全起见让用户暴露的明文密码次数越少越好，我们一般在web项目中，大多数采用保存的session中，然后在存一份到cookie中，来保持用户的回话有效性。但是在app提供的开放接口中，后端服务器在用户登录后如何去验证和维护用户的登陆有效性呢？回到目录设计对于敏感的api接口，需使用https协议 https是在http超文本传输协议加入SSL层，它在网络间通信是加密的，所以需要加密证书。https协议需要ca证书，一般需要交费。回到目录　　1、原理用户登录后向服务器提供用户认证信息（如账户和密码），服务器认证完后给客户端返回一个PID令牌，用户再次获取信息时，带上此令牌，如果令牌正取，则返回数据。对于获取Token信息后，访问用户相关接口，客户端请求的url需要带上如下参数： ① 时间戳

Ubuntu Java: Find a specific program's pid and kill the program

阅读更多关于 Ubuntu Java: Find a specific program's pid and kill the program

问题 I'm trying to make an application that checks if this specific application is running, then kill the app after a specified amount of time. I'm planning to get the pid of the app. How can I get the pid of the app? Thanks 回答1: You might try ps -aux | grep foobar for getting the pid, then issuing the kill command against it, alternatively you might want to use pkill foobar , in both cases foobar being the name of the app you want to terminate. 回答2: pid's for java processes -e.g ps -aux | grep

window 下某个端口被占用

阅读更多关于 window 下某个端口被占用

window 下某个端口被占用 1、开始—->运行—->cmd，或者是window+R组合键，调出命令窗口； 2、输入命令：netstat -ano，列出所有端口的情况。在列表中我们观察被占用的端口，比如是1224，首先找到它； 3、查看被占用端口对应的PID，输入命令：netstat -aon|findstr “8081”，回车，记下最后一位数字，即PID,这里是9088； 4、继续输入tasklist|findstr “9088”，回车，查看是哪个进程或者程序占用了8081端口，结果是：node.exe 或者是我们打开任务管理器，切换到进程选项卡，在PID一列查看9088对应的进程是谁 TASKKILL /F /PID XXXX 杀掉某个pid的进程终极杀招，跳过上面4步一招直接杀死所有java程序占用的端口。 taskkill /f /im java.exe 来源： https://www.cnblogs.com/xiaowangbangzhu/p/12015490.html
