PowerShell Network Requests: PowerShell Proxy Request Configuration

Figuring out the underlying logic of PowerShell agent configuration

Many people think that using a proxy in PowerShell is simply a matter of filling in an address, but in fact, there is aprotocol matchingFor example, if you use the Socks5 proxy provided by ipipgo to hardwire an HTTP request, it will not connect. For example, if you use the Socks5 proxy provided by ipipgo, if you apply it to HTTP requests, you will not be able to connect. Here to teach you a local way: first look at their own proxy type, and then go to the corresponding parameter settings, the success rate directly doubled.

Two real-world configuration options

I've personally stepped in the pits with both of the following methods, and now I'm sharing the stable version of the solution:

Global Configuration of Environment Variables

$proxy = "111.222.33.44:8080" replace with your ipipgo proxy address
[System.Environment]::SetEnvironmentVariable('HTTP_PROXY', $proxy, 'User')
[System.Environment]::SetEnvironmentVariable('HTTPS_PROXY', $proxy, 'User')

This trick is suitable for scenarios where you need to hang the agent for a long time, such as friends who do data collection. Remember to restart the terminal after setting up, otherwise the variables will not take effect. This method is especially recommended when using ipipgo's static residential IP, and the stability is excellent.

Dynamically specified at request

$webClient = New-Object System.Net.WebClient
$webClient.Proxy = New-Object System.Net.WebProxy("socks5://45.76.112.88:1080")
$response = $webClient.DownloadString("http://example.com")

This writing method is suitable for temporary proxy switching scenarios, such as testing the effect of different regional IP. Key Points to Noteprotocol prefixMake sure you write it right, ipipgo's proxy supports HTTP/HTTPS/Socks5, don't get confused.

Guide to avoiding pitfalls (real experience of stepping on mines)

Three typical problems I encountered while helping a customer debug recently:

1. Certificate error: SSL error when using HTTPS proxy is actuallySystem root certificatesNo update. Run it.Update-Help -ForceThat'll solve it.

2. Connection timeout: check whether the proxy IP is blocked by the target site, this time change to ipipgoTK Linehave an immediate effect

3. Unstable speed: When the dynamic residential IP encounters speed fluctuations, add aStart-Sleep -Milliseconds 200interval, the acquisition success rate is directly increased by 60%

QA High Frequency Questions Collection

Q: I set up a proxy but it didn't take effect?
A：There are three steps to troubleshoot: ① Use thecurl -x Proxy IP Test URLSee if you are connected ②Check firewall settings ③Contact ipipgo customer service to check IP status

Q: How do I choose a package for Enterprise Capture?
A: the average daily request volume <50,000 times with dynamic standard version, more than this amount is recommended on theDynamic Residential (Business)Package with automatic IP rotation. If you need a fixed exit IP, choose a static residence, 35 dollars/IP/month is not expensive.

Q: Proxy requests return garbled code?
A: Add an encoding statement in the request header:
$webClient.Encoding = [System.Text.Encoding]::UTF8

Why recommend ipipgo

Real life experience after using them for over three years: theircross-border rail lineIt is indeed stable, especially when doing overseas business, the delay can be controlled within 200ms. Focus on three useful functions:

① API extraction with automatic authentication, directly plugged into the code can be used
② Windows clients support proxy rules for streaming, eliminating the need to write scripts.
③ Customer service can customize the billing plan according to your business volume, unlike other companies where you have to buy a fixed package.

Recently, I've been helping customers to do crawler projects, using their dynamic residential enterprise version, 1 hour to deal with 200,000 requests without problems. Package price is also real, the standard version of more than 7 yuan 1 G flow, than self-built proxy pool to save a lot of trouble. Need to customize the program directly to their technical chat, according to business scenarios with exclusive IP library.
