Nowadays, red packets are quite popular, and everyone will use them. it's time to celebrate the new year and the red packet will start again. let's share with you an algorithm for implementing the red packet sending program in php, it is very practical. we recommend it to our friends here. if you need it, you can refer to it. This article describes the red packet algorithm implemented by php. Share it with you for your reference. The details are as fo

It seems that the problem has not been resolved, but look at the second line of hints, the prompt is: struts-default.xml:69:87, that is, the error message is not the same as the earlier, that is, this is not a problem, the previous problem has been resolved, This is a new issue, and the imported package file is:Freemarker-2.

I have a need for this. To debug the PHP program when the Android app launches a request to the server. Break the target down, about the following steps debugging PHP using Eclipse+xdebug, while XDEBUG triggering breakpoints requires the Get method to pass a parameter or set a cookie, I use a cookie method (I think this method is better) That is, to find a way to get the app to launch a request with cookie information, because app development I am not familiar with, so can only think of oth

How to capture packets using tcpdump in Android Tcpdump and Root permissions are required for Packet Capturing. tcpdump will be downloaded after this article.First, pass tcpdump to your mobile phone and use the adb command (sometimes it may be a problem to put the SD card. I can use it once, but it won't work after I brush another ROM ): Adb push tcpdump/data/local/ Connect the computer to the mobile phone, open CMD, and execute: Adb shellChmod 67

1. If you do not yet know how to configure proxy addresses, you can look at another essay in the same category. No details are described here.2. Import the certificate open port, configure the browser agent (for example, Firefox)3. Enter HTTP://BURP in the Address bar, and enter to download the certificate4. Note that the certificate here can not be 0 bytes, or to find the cracked version (for this reason, wasted my day to find the reason)5. Finally, import the certificate into the browser, in F

, manually add the agent. Proxy host Name: Use the PC's native IP addressProxy Server port: Using the port value set by Charles, Charles configures the port in the same way2. Configure the agent for the first time, you need to allow the operation on the PC side, see let (if you accidentally closed the following box, you can reconfigure the mobile phone agent)Step Three: PC-side Charles installs the HTTPS certificatehelp->ssl proxying->install Charles Root Certificate, and then trust the certific
