The Hidden Role of Proxy IPs in Data Collection
Do data collection of the old iron understand, directly with their own servers wildly send requests, minutes will be the target site pulled black. In particular, such a large platform as YouTube, the monitoring of abnormal traffic is more strict than the neighborhood guard. At this time you need to find a reliable "middleman" - that is, proxy IP to cover.
Let's take a real scenario: Zhang San wanted to analyze the interaction data of popular videos, and used his office network to tune the API 200 times in a row, and as a result, the next day the whole company's IP was blacked out by YouTube. This scenario usesDynamic Residential Proxy IPIt can be perfectly solved, each request is changed to a "vest", the platform simply can not feel the real source.
The right way to open a compliant API
First the highlights:Never crawl a web page directly!YouTube officially provides Data API v3 with 10,000 free calls per day. The registration process is also a 5-minute affair:
1. Login to Google Cloud Console
2. Create a new project → Enable YouTube Data API
3. Generate the API key (looks like AIzaSyBxoxxxxxxxxxxxxxxxx) on the credentials page
Note that this key should be kept safe, leaking it will allow others to steal the credit. It is recommended to put it in an environment variable, don't be stupid and write it directly in the code.
Proxy IP real-world configuration tips
Here's an example of ipipgo's proxy service to demonstrate how to integrate a proxy into your code. One good thing about their proxy is that it supportsUser Name Password Authentication, no need to toss whitelist:
import requests
proxies = {
'http': 'http://用户名:密码@proxy.ipipgo.io:31112',
'https': 'http://用户名:密码@proxy.ipipgo.io:31112'
}
response = requests.get(
'https://www.googleapis.com/youtube/v3/videos',
params={
'part': 'statistics',
'id': 'video id',
'key': 'your API key'
},
proxies=proxies
)
After using his proxy, the success rate of API request directly soared from 63% to 98%. Especially when doing batch collection, it is recommended to enable theAutomatic IP RotationFunction, specifically in the background settings to check the "every 5 minutes to change the export IP".
Three Essential Strategies for Anti-Blocking
Even if you use a proxy you can't do whatever you want, you have to be strategic:
risk point | prescription |
---|---|
Excessive frequency of requests | Keep it under 3 times per second |
Poor IP quality | Choose ipipgo's premium static IP packages |
identical parameters | Mixed use of video ID, channel ID, and many other query criteria |
Special note: If returning403 error codeDon't rush to add proxies first, it may be that the API quota is used up. At this time, go to the quota page in the Google background to apply for raising the limit, which is more useful than changing IP.
