foreword
- As a programmer,
"ip"it must be very familiar to us. ipThe full name of Internet Protocol refers to the protocol for interconnection between networks. It is generally referred to as the Internet Association for short. This is a protocol specially designed for computer networks to communicate with each other.- Speaking of, it is natural that dynamic ip , static ip and ip proxy are
ipindispensable . - Dynamic IP address (Dynamic IP) refers to the way of IP address allocation only when needed. Dynamic IP addresses correspond to static IP addresses.
- The so-called dynamic means that Telecom will randomly assign an IP address every time you surf the Internet; static means that an IP address is fixedly assigned, and this address is used every time.
- Then this article will introduce the benefits of using proxy ip, and what are the useful proxy ip websites and cases of using dynamic ip, let's take a look!
1. Proxy ip
1.1 Introduction to proxy ip
The proxy ip is a server between the browser and the web server. If you use the proxy IP, the Request signal will be sent to the proxy server first, and the proxy server will get the information required by the browser and send it to your browser. .
1.2 Proxy ip classification
Regarding proxy ip, there are actually many types, and various classifications can be extended according to different categories.
Such as anonymity classification, aging classification, protocol type classification, and purity classification, etc. For specific category information, please refer to the picture below.
1.3 Advantages of proxy ip
There are many advantages of proxy ip, it can not only improve our access speed, but also protect our information.
The proxy ip adopts multiple encryption protocols, and supports whitelist and account password verification at the same time, which can avoid information leakage and effectively guarantee information security.
There are also some advantages in other aspects, you can refer to the following pictures I summarized.
1.4 The necessity of proxy ip
There are many advantages of using proxy ip, but there is another important point is the necessity of using proxy ip, especially for some crawlers, it is a very important part.
Because some websites may have added an anti-crawling mechanism , one of the most important ways is that when a large number of access requests are found for a single ip, the corresponding ip will be added to the blacklist and will not respond (that is, what we often call IP blocking).
In this case, our crawler will lose its function, so this situation must be avoided.
The role of proxy ip at this time can be said to be very important, so this is also one of the important reasons for using proxy ip.
2. Choose the right platform
I talked about some advantages of proxy ip earlier, so we still need to choose a suitable proxy ip platform to make us more comfortable to use.
There are many websites about proxy ip on the Internet. When you open Baidu and search, the screen is full of dazzling advertisements, and you don’t know how to choose.
The key is that it is okay to say that it can be used. I am afraid that after a long time of operation, it will tell you that it cannot be used. Some can be used but the price is ridiculously high.
So let me recommend a really easy-to-use platform for everyone, so that many friends will not be directly persuaded by those advertisements. It is always good to be good at learning and trying, but the important thing is to choose the right direction!
2.1 Introduction to IPIDEA
IPIDEA is an IP proxy platform that provides high-quality big data proxy services for global users. It currently has tens of millions of real residential IP resources, including more than 220 countries and regions, with more than 40 million daily updates, which are aggregated into a proxy service pool and provide API access. It supports multiple protocol types such as http, https, socks5, and has multiple usage methods such as API form and account password, which is very easy to use.
And they support real dynamic residence, static residence ip, etc., which can make our proxy ip more real and stable.
Newly registered users still have free quota to claim. Those who are interested in proxy ip can directly click on the link to register and then claim the free quota first: IPIDEA website
2.2 IPIDEA application scenarios
As a global Internet big data IP resource service provider, IPIDEA has many application scenarios.
Scenarios such as brand protection, advertising verification, website testing, stock market data, market research, etc. can use IPIDEA's products.
2.3 IPIDEA Get Proxy API
After entering the website, click获取代理 -> API获取
Then select the quantity and region according to your preferences, and use the default options for others, and then click the Generate link below
Click "Confirm Add Whitelist" or manually add "Other Whitelist"
Then copy the link we generated, this link should be saved, and it will be used later when crawling with Python.
Copy the link separately to the browser and open it, and you will see the IP generated just now. This part can be used for manual setting of our own browser.
2.4 Set the dynamic IP proxy in the browser.
Set the proxy ip according to the browser, and change the IP by changing the computer browser to browse other web pages. But for other consumers who need to change IP frequently, it is still not so convenient.
In the IPIDEA official website tutorial, there are methods to set proxy ip according to different browsers. The operation is very simple, and you can use different browsers to set according to your own needs.
After setting, you can check your IP address through the search engine.
In this way, we have successfully set up the proxy ip, and then we will use a case to really use the proxy ip to do something!
3. Case introduction
Let's use a case to actually demonstrate how to use the proxy ip.
3.1 Cross-border e-commerce
Since there are too many industries to choose from, here is a case study of a popular e-commerce platform in the past two years.
When it comes to e-commerce platforms, everyone is sure to be familiar with them. It can be said that they are affecting our lives all the time.
Some friends may have doubts, what is the relationship between proxy ip and e-commerce platform? It really matters, that is cross-border e-commerce .
3.1.1 Overseas ip proxy
For now, mainstream e-commerce platforms, such as Amazon, eBay, etc., are still not happy to see store IPs jumping around, and will be easily blocked, and a big platform like Amazon, in many countries or regions With sub-sites, IPs in different regions are required to operate separately.
An unqualified agent is not only unsafe and unstable, but most importantly, it may be used before, which will directly lead to the failure of the merchant to register or even be associated.
So if we have the needs of cross-border e-commerce, then we need a stable proxy ip, otherwise there may be problems of one kind or another.
Here IPIDEA is doing well enough, which is also one of the reasons for recommending the use of the IPIDEA website .
3.1.2 Obtain the data of a hot-selling product on Amazon
Use Python to write a simple ip proxy example, and you can refer to it later when you use Python to crawl some other data.
Use the requests module directly, and then add a random request header module fake_useragent and UserAgent.
The following is a simple example of obtaining the data of a hot-selling product on Amazon. The interface content is as follows:
The code example is as follows:
# 搜索：[呆呆敲代码的小Y]，回复[白嫖]获取超多精品编程学习资料！！
# 爬虫使用代理IP
# 导入模块：requests、fake-useragent、UserAgent
import requests
from fake_useragent import UserAgent
# 要访问的url地址
url='https://www.amazon.cn/s?bbn=106200071&rh=n%3A106200071%2Cp_89%3AHuawei+%E5%8D%8E%E4%B8%BA'
# 随机请求头
headers={
'User-Agent':UserAgent().random}
# 代理ip 的API(IPIDEA网站获取的)
api_url='代理ip 的API(IPIDEA网站获取的)'
res = requests.post(api_url,headers=headers, verify=True)
# proxies = {'协议': '协议://IP:端口号'}
proxie = "https://%s"%(res.text)
proxies = {
'http': proxie}
# 打印所有的代理ip
print(proxies)
# 获取亚马逊某热销商品数据 python模块测试并输出结果
html=requests.get(url=url,headers=headers,proxies=proxies).text
print(html)
The running effect is as follows:
Here is just an example of using the proxy ip to obtain the data of a hot-selling product on Amazon . There are more things that can be used if you make good use of the proxy ip. Let's experience it yourself!
As long as the crawler can be used, we can customize a time to automatically switch the ip, so that when crawling a large amount of data, it will avoid restricted access and improve the efficiency of the crawler.
Compared with other proxy websites using IPIDEA, I feel that its connection is very stable. It is worthy of being a large service provider with 90 million+ IP resources, and it has the advantages of unlimited concurrency and support for precise positioning of city IP.
The method of use is also very simple, and there are corresponding tutorials for different usage methods on the official website, which is very friendly for novices who use proxy ip for the first time.
In the process of using it, there is also a sense of security. There is no need to worry about various problems with the proxy ip, and the experience is full!
3.2 Get TapTap game leaderboard data
The above describes a case of obtaining Amazon's hot-selling products, and then another case of obtaining TapTap game ranking data.
The content of the interface is as follows, just use the above code to replace the access link with the game leaderboard.
The running effect is as follows
Summarize
- Regarding the function of proxy ip , it can do more than just crawl data.
- You can also do more fun and interesting things, such as brushing ##, climbing ##, etc., and you can realize different functions according to your own needs.
- The point is to use IPIDEA to obtain the corresponding API link and then perform corresponding access.
