socks5 proxy function API library: Python/JAVA call Socks5 proxy interface examples

Hands on with putting ipipgo's socks5 proxy into code

Today we do not organize false, directly on the hard food. Proxy ip with the old iron know, socks5 protocol that is a fragrant, especially when dealing with network requests. But how to put it into the code? It depends on what programming language you use.

Veteran Python drivers look here

Veterans of Python know how handy the requests library is, but to get this thing to go proxy, you have to play it this way:

import requests
from requests.auth import HTTPProxyAuth

proxies = {
    'http': 'socks5://user:password@proxy:port',
    'https': 'socks5://user:password@proxy:port'
}

response = requests.get('destination URL', proxies=proxies)
print(response.text)

Here's the point:Replace the "user", "password" and "proxy server" with the authentication information you got from ipipgo. Their proxy server address is lying in the console, don't be stupid and copy this code directly!

Java Tackle Lion Don't Walk Away

Play Java friends look at this paragraph, with HttpClient if you have to configure so:

import org.apache.http.HttpHost; import org.apache.http.auth.
import org.apache.http.auth.AuthScope; import org.apache.http.auth.
import org.apache.http.auth.UsernamePasswordCredentials; import org.apache.http.client.
import org.apache.http.client.CredentialsProvider; import org.apache.http.client.
import org.apache.http.impl.client.BasicCredentialsProvider; import org.apache.http.impl.client.
import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.
import org.apache.http.impl.client.HttpClients; import org.apache.http.impl.client.


credsProvider.setCredentials(
    new AuthScope("Proxy Server", Port), new UsernamePasswordCredentials(
    new UsernamePasswordCredentials("Users", "Password"));;

CloseableHttpClient httpClient = HttpClients.custom()
    .setProxy(new HttpHost("proxy server", port))
    .setDefaultCredentialsProvider(credentialsProvider)
    .build();

Here's a pitfall to be aware of: ipipgo's socks5 proxyMust be authenticated with an account passwordDon't even think about doing the anonymous access thing. They have a large pool of residential IPs, over 90 million home IPs to pick from, but you have to play by the rules.

First Aid Guidelines for Common Rollover Scenes

Q: What should I do if I can't connect to the agent?
A: First check the three suits: 1. proxy address is not right 2. port is not socks5 special port 3. account password there is no slip hit the wrong!

Q：Return 407 Agent Authentication Error?
A: Ninety-nine percent of the authentication information is not transmitted correctly, check the location of the username and password in the code. If you use ipipgo, remember what they use at home isSeparate account systemDon't try it with an account from another platform.

Q: What about a snail's pace?
A: Try cutting to a node closer to your target server. ipipgo covers more than 240 countries and regions, don't stick to one place's IP. dynamic residential IP is suitable for scenarios that require frequent switching, static IP is suitable for long-term tasks

Why ipipgo?

This is not the old king selling melon. Used to know, some proxy service providers claim to support socks5, the actual use is not disconnected or card into a dog. ipipgo's full protocol support is real, the underlying use of enterprise-class proxy transit cluster, unlike some small workshops to take the open-source software to change the out of the sale.

For example, if you want to do distributed collection, you have to start dozens of proxy connections at the same time. Ordinary proxy has long been collapsed, but ipipgo's load balancing architecture can automatically allocate the optimal line, which is particularly important in practice. Don't ask me how I know, say more are tears (once by the unreliable agent pit)

Tips for avoiding pitfalls

1. It is recommended that logs be opened during the debugging phase, and Python can add them to requests.verify=FalseTemporarily skipping certificate validation
2. Java remember to close the httpClient, do not let the connection pool burst
3. Remember to set the timeout parameter for long tasks, so that the program does not have to wait.
4. When you encounter weird problems, try another IP first, maybe the current IP is banned by the target website.

Lastly, I would like to say one thing: This proxy thing is about the word "stable", don't try to be cheap and use a pheasant service provider. Like ipipgo such a professional operation and maintenance team to keep an eye on the problem can quickly switch lines, this is the attitude of the serious project. Code again 6, no good proxy support is also useless, you say is not it?
