Python initiates a POST request: Python proxy POST request

Hands-on with Proxy IP to send POST requests

The old iron engaged in crawling must have encountered the IP blocked the bad things, this time to rely on proxy IP to save the scene. Let's not whole false today, directly on the dry talk about how to use Python with proxy IP to send POST requests. Remember ah, here said the proxy IP are legal and compliant, do not move the wrong idea.

Why do I need a proxy IP to send a request?

For example, you submit form data in bulk on a website, the same IP crazy operation, minutes to be pulled black. Proxy IP is like wearing numerous masks, each request for a different "face", the server will not recognize you. Here we recommend usingipipgoThe proxy service, the actual test of their survival rate can reach 98%, more reliable than some motionless failure of the pheasant agent.

 Basic POST request template
import requests

url = 'https://目标网站.com/api'
data = {'key1': 'value1', 'key2': 'value2'}

 Replace this with your own ipipgo proxy parameters
proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
    'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}

response = requests.post(url, data=data, proxies=proxies)
print(response.text)

Proxy IP configuration three big pitfalls

The areas where newbies are most likely to fall head over heels have to be highlighted:

1. Wrong authentication informationThe proxy format for ipipgo is username password @ gateway address, many people misspell the port number as 9021 (correct is 9020)

2. timeout setting: It is recommended to add the timeout parameter, if there is no response for more than 3 seconds, then change the proxy.

3. Exception handling: try...except to wrap when the proxy is unstable

 Advanced version with exception handling
from requests.exceptions import ProxyError

try: response = requests.post(url, proxies=proxies, timeout=5)
    response = requests.post(url, proxies=proxies, timeout=5)
except ProxyError as e.
    print(f "Proxy is not working! Change your IP: {e}")
     Here you can call the ipipgo API to change the IP automatically

How to choose a proxy IP package

ipipgo's dynamic mixed dialing package can reach 500+ requests/second in real-time concurrency, which is especially suitable for scenarios that require a large number of data submissions. Their IP pool is updated daily with 20% or more, much more conscientious than those service providers who don't change their IPs for years.

Practical QA session

Q: What should I do if my proxy IP suddenly fails?
A: It is recommended to add a retry mechanism in the code, and at the same time contact ipipgo customer service for a new IP, they respond to thieves fast, usually within 5 minutes to solve the problem!

Q: POST request returns 403 error?

Q: How do I verify if the agent is in effect?
A: Add a checking step in the code, visit httpbin.org/ip to see if the returned IP is a proxy IP

1. Don't try to buy a junk proxy cheaply, it's more expensive to waste your time in the end.
2. Important business is recommended to use ipipgo's enterprise-class agent, there is an exclusive channel without congestion
