What is a hidden proxy?

1.conceptThe high-hiding proxy has a good disguise for visitors, using the original IP to hide the information of the proxy, the target is only treated as ordinary visitors, the highest degree of hiding, so it is called the high-hiding proxy.2. Principle of proxy IPWhen you connect to a proxy server, the data jumps through the proxy server, which records your real IP(or not, depending on how the proxy server is configured). Therefore, the real address cannot be found until the owner of the proxy server is found and the IP access record is also queried. (Generally not, except in government law enforcement)3. advantages(1) High-hiding proxy has the best concealment, it not only replaces the user's own IP with random IP, but also hides the proxy information, so that the accessed object cannot detect that the user is accessed through proxy IP, which is not able to be achieved by transparent proxy and ordinary anonymous proxy.(2) Because high-hidden proxy IP can completely hide the USER's IP and information, and will not have any feeling on the target access object, the advantages of high-hidden proxy IP are also obvious, and users are more assured to use it.In the choice of IP proxy, can be roughly divided into three kinds, from all aspects of the performance of the use of high proxy is undoubtedly the best choice.The above is the introduction of high proxy, compared with other proxy methods, the advantage is very obvious.Roxlabs provides 500MB traffic, which can be claimed after registration and login. Contains IP resources from many countries in the world, which can be extracted and used.

What is the role of computer servers address change in life?

What is the role of computer servers address exchange in sales? Without bricks-and-mortar stores, our traditional way of selling is impossible, not without fixed customer flow. However, with the development of The Times, the information technology is not only more and more developed, but also more and more common in the sales industry. In addition, due to the low threshold of many e-commerce industries, a large number of people began to pour into the e-commerce industry or make investment. So what is the role of computer switching servers addresses in sales? The following xiaobian will introduce it to you: The sales way of e-commerce is different from the sales way in our traditional sense. The particserversants should be more active and the objects come from all over the country and even all over the world. So, how do we find these worldwide guests without leaving home? At this point we have to use the computer to change the servers address. Take the agent servers software as an example, it can not only allow sales combined with their added customer source software to add from the national crowd, but also allow users to automatically replace servers. This helps salespeople increase their customer base, but they must not disclose users' private information online. E-commerce sales are also becoming more and more popular.If you need multiple different proxy IP, we recommend using RoxLabs proxy:https://www.roxlabs.io/?, including global Residential proxies, with complimentary 500MB experience package for a limited time.

What is web proxy?

Web proxy is a new term that many people recognize, but it is not the case. The term "web proxy" has been used in foreign countries and has become an important means of foreign marketing. It has been widely used and highly appraised. 1, Web proxy, simple explanation is to replace the hypertext protocol of the Web page, and can do some blocked websites can be accessed. In addition, in the process of using the agent, you can access some foreign websites at a faster speed. But to use a proxy, you need to have a server, and choose the best foreign one. For the ash industry or a large number of marketing industry, the sense is a good batch, efficient marketing assistance. 2. From the practical point of view, it is a transfer station similar to a data connection transfer station function. Some data can be bridged, quickly transmitted, and computer collated into the user's computer screen to see the image. And the proxy also has to assume the stability of data transmission, so many web proxies in server optimization, most will speed up the network, so that it has efficient transmission characteristics. In addition, from data security considerations, web proxy is also a camouflage technology. If the hacker is to engage in illegal activities, it can also prevent the loss of important information and data caused by the intrusion event to a certain extent. Can not say, the use of proxy does have many advantages, also has many advantages to the web development, choose this, I believe will not let a person down.If you need multiple different proxy IP, we recommend using RoxLabs proxy:https://www.roxlabs.io/?, including global Residential proxies, with complimentary 500MB experience package for a limited time.

Do you know about free web crawlers?

The growing need for big data is pushing people deeper into the ocean of data. Web crawlers play an important role in the preparation of Web pages for crawling. Today, the three main ways people access data on the Web are: Take advantage of the public API provided by the site. Write a web crawler. Use automatic web crawler tools. Based on my expertise in web scraping, I will discuss four free web scraping tools (web scraping, data extraction, data collection) for beginners. What is the use of a Web crawler?The purpose of a Web scraping tool is to crawl or grab data from a Web site.It can also be called a web harvesting tool or data extraction tool (actually it has many nicknames, such as Web crawler, web crawler, data grabber, spider). It scans the web and searches the content quickly, and then collects data on the web. One benefit of a bulky Web crawler is that no programming skills are required. That said, it should be user-friendly and easy to use. § Crawlers on the Internet help people gather a lot of information that they can access later.A powerful web crawler should have the ability to export the collected data to a spreadsheet or database and store it in the cloud. In this way, the extracted data can be added to an existing database through the API. You can choose the web crawler as needed. If you need multiple different proxy IP, we recommend using RoxLabs proxy:https://www.roxlabs.io/?, including global Residential proxies, with complimentary 500MB experience package for a limited time.

What are the anti-crawler strategies and countermeasures?

Due to the continuous development of the Internet, the war between crawler and anti-crawler has never stopped. Today xiaobian for you to share a few complex anti-crawler strategies, let's see ~. 1. Data masquerade. On a Web page, the crawler can monitor traffic and then simulate a normal request from the user. In this example, some sites add complexity by disguising the data. For example, a website with a display price of $299, CSS masquerade for DOM trees. You must do some calculations in the CSS rules to get the correct values. In this case, crawlers have to be very careful, because once the target site is modified, the rules change and the crawler data becomes invalid. 2. Parameter signature. APP calculates request parameters through encryption algorithm to obtain signature. Signatures are typically timestamped and add a timestamp to the request. It works for a short time and is a fixed parameter. After the server sends the request, the server verifies the parameters, timestamp, and compares whether the signatures are consistent. If they are inconsistent, the request is considered illegal. It is often difficult to get encryption algorithms on the APP side, and decompilation is often required to get encryption algorithms. 3. Hide validation. Hiding validation is one of the most complex methods. For example, in terms of protecting websites, JavaScript requests for specific websites can give you specific tokens, so that each request produces a different token. Some sites even add special request parameters to invisible images to determine if they are real browser users. In such cases, it is often not feasible or very difficult to request the API directly, and this can only be avoided by using tools such as ChromeHeadless to simulate the user's behavior. 4. Stop debugging. One of these anti-crawler strategies is special. Once you open the browser's console interface, it triggers the browser's debugging instructions indefinitely. The site adds a debugger for all structural functions, called leonid-tq-jq-v3-min.js, which triggers the debugger when any object is generated. Its purpose is to protect code by preventing unexpected scripts or programs from being used for tracing and debugging. In this case, you can get around this limitation by building a modified JS file, removing the debugger keyword, using mitmProxy to forward traffic, intercepting leonid-tq-jq-v3-min.js, and sending the modified JS file back to the browser. If you need multiple different proxy IP, we recommend using RoxLabs proxy:https://www.roxlabs.io/?, including global Residential proxies, with complimentary 500MB experience package for a limited time.
