Regarding the http proxy, everyone’s initial understanding is that you can change the ip. The most common one is to lift the IP restriction. I don’t know anything else. Today I will introduce you to the HTTP proxy IP. Although there are many proxy IPs on the market, the use of one model is inconsistent and the effect is different. Let me introduce the usage of http proxy together.
1. Use of web crawlers
If a web crawler wants to collect a large amount of data in a short period of time, it needs to cooperate with the use of HTTP proxy IP. The web crawler is generally accessed programmatically and directly connects with the API.
What is the use of HTTP proxy IP for web crawlers? The main purpose is to break through IP restrictions and hide IP information.
In fact, web crawlers can have their own development space because it is convenient, efficient, and rapid to use crawler programs to crawl web information. At the same time, web crawlers are also restricted by the other party's IP. This is because:
For example, we now have a website. The content of the website is written hard by ourselves, but there will be many malicious competition objects. We use malicious program crawlers to crawl our own data, so in order to protect our own Website, I would rather kill a thousand by mistake than let one go.
In addition, the carrying capacity of the server is always limited. If a program has been overloaded to fetch server information, the server will easily crash.
Therefore, in order to protect the security of your website, an anti-crawl mechanism will be set up to reject web crawlers.
At this time, if you want to continue to visit this website, the HTTP proxy ip is very important. If the current ip address is restricted, you can change to a new ip address to ensure the smooth progress of the crawler.
2. Browser use
Open the internet option, check the proxy server "Use a proxy server for the LAN" in the LAN settings, fill in the IP address and corresponding port number, and refresh the browser IP after saving. This kind of service for replenishing effects can be used to break through the problem of website IP address restrictions.
For example, forum posting, question and answer promotion, SEO, manual registration, effect return visit, online shopping, baby collection, voting and like.
3. Direct use
Download the HTTP proxy IP software, install and log in and set the usage information. This type of software can select the IP line and modify the IP information regularly. For example, log in to the Zhiyou proxy IP on the computer and select the Guangzhou IP line to connect, and you can check whether the IP is modified in the browser. No matter what browser or other software is used, the recorded IP is the proxy IP, not your own. The real IP.
Data capture, online marketing, e-commerce ordering, and voting assistance all need proxy IP. Zhiyou proxy IP is a software that can be downloaded and used. It is very simple and suitable for all those who need to change their IP.
