PowerShell Settings: PowerShell Agent Configuration

First, PowerShell to engage the agent in the end what is the use?

Many old iron in the use of PowerShell to do automation scripts, often encounter the need to switch the network environment. For example, the crawler program to prevent blocking, or corporate intranet to dock servers in different regions. At this time, hanging a proxy IP is like a mask for the computer, both to protect the real address and flexible switching lines.

To cite a real case: last year, the operation of an e-commerce company's little brother used PowerShell to capture the price of competing products in bulk, and as a result, the IP was blocked on the third day. Later, they used ipipgo's proxy pool to rotate IPs, and the script ran continuously for two months without problems. This wave of operation directly save 3 manpower, the boss on the spot to add a chicken leg.

Second, hand to teach you to match the agent

Pay attention to the version number!PowerShell 5.1 and 7+ are configured differently:

 Universal configuration template (remember to replace it with your own IP)
$proxy = "http://username:password@ipipgo-proxy.com:8080"
[system.net.webrequest]::defaultwebproxy = New-Object system.net.webproxy($proxy)

Here's a pitfall to be aware of: if you use ipipgo'sDynamic Residential Agents, it is recommended to write the authentication information as a variable, so that it is easy to call it in a loop in the script. Their API can return available IPs in real time, which is much more flexible than writing a dead address.

Third, debugging skills to give away

Don't rush to run the script after configuration, first take this command to test the proxy pass or fail:

Invoke-WebRequest -Uri "http://ipv4.ipipgo.com" -UseBasicParsing

If the IP address returned is not the local address, it means the proxy is working. If you get a 407 authentication error, it's probably because you didn't write the right password. ipipgo's backend can check the number of connections in real time, so it's especially good for troubleshooting this kind of problem.

Fourth, QA time (white must see)

Q: What should I do if all the traffic goes to the proxy after the proxy is set?
A: Add [system.net.webrequest]::defaultwebproxy = $null at the end of the script and it will be restored!

Q: How do I break the company network with dual agents?
A: Ask ipipgo's tech support for a socks5 solution, their tunneling proxy can tunnel through multiple layers of NAT.

Q: The script suddenly can't connect to the proxy IP?
A：先用Test-NetConnection命令测端口通不通，ipipgo的IP存活率有99%，大概率是本地防火拦了

V. Why do you recommend ipipgo?

Used the blood and tears of 5 agency service providers:
1. Exclusive bandwidth is more than 10 times more stable than shared pools
2. Customer service is as responsive as a Hungry Horse rider
3. Flexible pricing scheme, no pain for small workshops with volume-based billing
4. Support hanging 3 standby nodes at the same time, automatic switching offline

Final scratch: use promo code when signing upPSPROXYYou can whore out 3 days of enterprise level agents. If you encounter technical difficulties, directly find their technical brother video remote, hand in hand to teach until you can use. Brothers engaged in automation scripts, the agent of this piece really do not need to die by themselves.
