Every time you use string mode matching, you always have to go through the instructions on the Lua official website. There is no detailed description on the Internet, and many friends have asked me about the content, in fact, there are three difficulties: I am not familiar with the regular expression of Lua; The other is unfamiliar with the usage of several functions provided by the string library in Lua; Another point is that the string library of Lua puts forward a new concept called

Getting started with Linux: How to Use tcpdump to capture tcp syn, ACK, and FIN packets Q: I want to monitor TCP connection activities (for example, three handshakes for establishing a connection and four handshakes for disconnecting ). To accomplish this, I only need to capture TCP control packets, such as SYN, ACK, or FIN flag related packets. How can I use tcpdump to

Python Web data capture full recordIn this article, I'll show you a replacement for a request based on the new Asynchronous Library (Aiohttp). I used it to write some small data crawlers that are really fast, and I'll show you how. The reason for this diversity in codego.net is that data "crawling" actually involves a lot of problems: you don't need to use the same tools to crawl data from thousands of pages while automating some Web workflows (such a

The previous attempt to crawl Baidu hot data, this time continue to choose to use Bing Search to grab pictures under the practice, the code in the bottom for your reference. The program needs to pass in three parameters, picture keywords, picture save path, need to crawl the number. There may be some errors during the run (mostly network errors, such as timeouts, etc.) I capture here only to print out and then skip. The URL request to page through the

to press the Capture button, the screen but ran away. If you use the FastStone capure software, because it defines the shortcut key "Shift+printscreen" that captures the Window object by default, when you expand to a screen menu and need to crawl, the mouse pauses to the level menu and then presses the shortcut key above to box select and crawl the Level menu ( Figure 1). Small tip: If you need to intercept with all levels of menus and

----C + + Builer VCL provides a processing mechanism for most Windows messages, which is sufficient for a generic application, but VCL is not all-encompassing, and how do you capture Windows messages that are not handled by VCL? C + + Builder uses a message-map mechanism to link a particular Windows message to a function in the code through a message image table, and this function is called when the window captures the message, which is very similar t

In practical development, in order to solve the problem of Ajax cross-domain requests, the target's Web API is requested and returned by a controller on the same domain at the server. To facilitate debugging of such requests, we want to be able to monitor these requests through Fiddler. Fiddler official gives the Java application How to configure: Configure a Java application to use Fiddler. But we found that if we use org.apache.http.impl.client.DefaultHttpClient, neither of the official method
