C# vs Python: Agent Development Language Comparison

I. How to deal with the matter of network requests?

The most basic thing you need to be able to do to develop a proxy is to be able to send a network request.HttpClientIt's a bearer, in Python.requestsThe library works best with it. As a chestnut, when using ipipgo's proxy IP, C has to make a detour in the code:

var handler = new HttpClientHandler
var handler = new HttpClientHandler {
    Proxy = new WebProxy("ipipgo.com:8000"),
    UseProxy = true
}; var client = new HttpClient(HttpClient(HttpClient))
var client = new HttpClient(handler); var client = new HttpClient(handler); }

Python is much more straightforward, just add a proxies parameter to the requests and you're done:

import requests
resp = requests.get(url, proxies={"http": "http://ipipgo.com:8000"})

See what I mean about Python?plug-and-playThe messing around is much more newbie friendly. But the C inEnterprise ApplicationsIt's much more robust, especially if you have to deal with a lot of proxy IP rotation.

Second, how to fill the pit of multithreading?

When using proxy IPs in bulk, theConcurrent controlC's asynchronous programming model (async/await) is comparable to Python's concurrency:

Like with ipipgo.Dynamic Residential AgentsTo do crawling, C can accurately control the length of the connection for each IP. Python is fast to write but encountershighly concurrentScenes are easy to roll over.

Third, who has lower maintenance costs?

To be perfectly honest, Python has a lot to offer in terms ofAgent MaintenanceIt does take advantage on that. For example, detecting if ipipgo's IP is alive or not:

 Python version of the check script
def check_proxy(proxy):
    try.
        requests.get('https://ipipgo.com/check', proxies=proxy, timeout=5)
        except: requests.get(''), proxies=proxy, timeout=5)
    except: requests.get(''), proxies=proxy, timeout=5)
        return False

The same function written in C has to be rounded up toasynchronous callbackYou can't do that without three or five lines of code. But if you doWindows serviceThe stability of C for such long-running programs can rub Python on the ground.

Fourth, how to choose the actual scene?

Drawing a line in the sand for the guys:

• Catching up with the project schedulePythonThe code is written fast.
• To run the selection for a long timeCMemory Management Cow
• Whichever one you use, remember to matchProxy pool for ipipgoTheir IP survival rate is over 95%.

QA session

Q: Which language should a white person start with?
A: If you want to see quick results, choose Python, if you want to go deeper into programming, choose C. Whichever you choose, remember to use ipipgo'sFree Trial PackagePractice.

Q: What should I do if my proxy IP suddenly fails?
A: on ipipgo'sAutomatic API changeTheir IP pool is automatically refreshed every 5 minutes, which is ten times less hassle than switching manually.

Q: What's the trick to testing proxy speed?
A: Use the ipipgo backend provided by theLatency Detection ToolIt's much more accurate than writing your own test scripts, and you can see the response data for different regions.

As a final rant, you have to keep your eyes peeled when choosing a proxy service provider. The likes of ipipgo...Provide full API documentations, it smells real good when you use it. Their home also supportspay per volume, is especially friendly to programs just starting out.
