. One of the biggest advantages of Python crawler writing is dummies. the lib functions such as Requests are equivalent to those of Curl. However, if you only do simple crawler, it is easier to use and has Beautiful SoupSuch a dummies lib is indeed very suitable for crawling. However, encoding may be a headache for beginners. I think PHP may be better. In fact, if it is not required by the team, I will write all my own crawlers using PHP. JavaScript is like a virtual machine in a vir

need to go to API provider, create app information for app, request permission, take Google as an example: Create a project in Google developers Console In APIs Auth-in APIs, choose to open the API that needs to be called In APIs Auth-Credentials, fill in the Redirect URIS (the address of the OAuth 2 callback) to create the client ID. After success, you will get the required client ID and client SECRET, keep it to yourself. In APIs Auth-Consent screen, fill in the app me

NginX and Node. js are born on the topic of building high-throughput web applications. They are designed based on the event-driven model and can easily break through the C10K bottleneck of traditional web servers such as Apache. The preset configuration can get high concurrency, but if you want to be cheap... syntaxHighlighter. all (); NginX and Node.

node. JS is a server technology that is used to build and run Web applications similar to what Asp.net,ruby on rails or the spring framework does. It uses JavaScript as the main development language, has a lightweight Web server with its own, and a large number of plugins for node package management (NPM), so you can shape your Web application to your own needs,

Worker processes, instead of multithreading + Shared Memory + locking, Although the shared memory performance is good, but there are security problems, the need for read/write locks. The granularity of the lock is too large, so only one thread is running. The lock is too complex and has a deadlock problem. Therefore, developers need to be very careful. 3. swoole coding is synchronous, not nested asynchronous callbackIf the

prevent XSS attacks.How do I confirm the dependency security of the project? With Node. JS development, There are hundreds of dependencies that can be easily seen.For example, If you rely on Express, to say exactly what it means to also rely on 27 other modules, manually detecting updates to these modules is not a choice!The only option is to automatically secur

Asynchronous programmingThe immediate manifestation of node. JS programming is callbacks, and asynchronous programming relies on callbacks: node uses a number of callback functions, all of which support callback functions. such as reading files.Here are the three nouns that do not understand threading and asynchronous and synchronous slightly.Threading: Simply sa
