HTTP Proxy IP Authentication Method｜User name and password autofill

First, why is your agent always stuck in the certification session?

Last week, a cross-border e-commerce friends complained: every time you use the agent to manually lose the account password, one day slip of the password in the letter "O" into the number "0″, resulting in the entire crawler script paralyzed for 3 hours. This kind of low-level error is actually common -Manual authentication has an error rate of 23%That's why we need automated solutions.

Two authentication modes for HTTP proxy IPs

1. Account password authentication (basic version)
This is the most common form of authentication, like opening a door with a key. Using ipipgo as an example, after logging into the console you will see the exclusiveAuthKey (username)respond in singingAuthPwd (password)The use of the program requires that it be spliced into a fixed format:

username:password@ip:port

Example setup in Python:

import requests proxy = "http://your_authkey:your_authpwd@gateway.ipipgo.com:8080" response = requests.get("http://example.com", proxies={ "http": proxy})

2. IP whitelisting authentication (advanced version)
Suitable for fixed server environments, directly in the ipipgo console to add the business server IP, eliminating the trouble of entering passwords each time. It is recommended to bind the primary and backup IPs at the same time, when the primary IP is abnormal, it will automatically switch to the backup line [1](@ref).

Third, the three kinds of auto-fill practical program

Option 1: Browser plugin automation (preferred by whites)
Installation of ipipgoProxy Assistant plug-inAfter:

1. Open the plugin settings page to import the account password
2. Automatically pop-up authentication box when accessing websites that require proxies
3. Check the "Remember password" box for permanent autofill.

Chrome was measured to reduce duplicate input operations by 87% [6] (@ref).

Option 2: Code environment variable configuration (a must for developers)
Add it to the system environment variables:

export HTTP_PROXY=http://authkey:authpwd@gateway.ipipgo.com:8080 export HTTPS_PROXY=http://authkey:authpwd@gateway.ipipgo.com:8080

This way all requests based on this environment will automatically carry the authentication information, avoiding duplicate configurations in each script.

Option 3: Password manager linkage (high level play)
Stores ipipgo's authentication information in the1PasswordmaybeBitwardenand other password managers through API interfaces:

• Automatically synchronize agent configurations across multiple devices
• Automatic reminder to renew passwords before they expire
• Automatically locking out agent privileges on abnormal logins [17](@ref)

IV. Guide to avoiding pitfalls: five major reasons for certification failure

1. Problems of escaping special symbols
Password contains@, #When you use symbols such as "P@ssw0rd", you need to do URL encoding. For example, "P@ssw0rd" is converted to "Pssw0rd".

2. Failure of authentication due to clock desynchronization
There have been users who failed Token verification due to the server time being 3 minutes slower than the actual time. It is recommended to enable theAutomatic time calibrationFunction.

3. Concurrent requests exceeding limits
The default number of concurrency for a single authenticated account is 50 threads, exceeding which will trigger a 407 error. In crawler scenarios it is recommended to enable ipipgo'sDynamic Session Poolfunction to automatically assign multiple authentication accounts.

4. Geographic IP library not updated in a timely manner
A user is using a US IP saved half a year ago, which has actually been reclaimed and assigned to a Brazilian user, resulting in authentication failure. It is recommended to enable ipipgo'sIP Freshness Testingfeature to automatically filter expired resources.

V. Frequently asked questions

Q: Can auto-fill passwords be stolen by hackers?
A: ipipgo uses military-grade encrypted storage, and all authentication information has beenAES-256 encryptionProcessed and stored in segments on different servers. Even if a single server is breached, the complete authentication data cannot be restored.

Q: What if the whitelisted IP changes servers?
A: Open at the consoleIP Floating Licensefunction, allowing 3 IP changes per month. Before major adjustments, it is recommended to contact customer service to apply for temporary expansion.

Q: How can I test if the autofill is working?
A: Access provided by ipipgoCertification Test Page::

1. "407 Proxy Authentication Required" is displayed when there is no authentication.
2. Display detailed parameters of the current proxy IP after successful authentication
3. Authentication time consumed for this request can be viewed (normal should be <200ms)
