Curl using SOCKS: proxy IP detailed setup steps API call tutorials

Hands-on with Curl to play SOCKS proxies

Let's nag some real today, a lot of friends do data collection often encountered IP was blocked the bad things. This time SOCKS proxy is a lifesaver, but how to use with Curl? Don't worry, follow the steps to go right.

Why SOCKS Agent?

More than an HTTP proxy, this SOCKS5 thingy isunder coverThe SOCKS proxy can transfer various types of data. Like we do overseas e-commerce price monitoring, using SOCKS proxy can avoid being recognized by the target site as a robot. Here we recommend using ipipgo static residential agent, 35 dollars an IP with a whole month, cheaper than drinking milk tea.

Local Environment Configuration

Make sure your computer is loaded first.Curl 7.21.7 or higher, older versions may not support the socks protocol. Open a terminal and type:

curl --version | grep Protocols

Seeing https/socks means it works. If it doesn't show up, we recommend going to the official website and getting a new version.

Sample code

Let's say we get the socks5 proxy from ipipgo:

curl -x socks5://user:pass@gateway.ipipgo.net:1080 https://target-site.com/api/data

Be careful to replace the user with your own account and the pass with the corresponding password. If you encounter a connection timeout, it is likely that the proxy IP has been banned by the target site, then quickly change the alternate node provided by ipipgo.

API auto-fetching proxies

ipipgo's API calls are easy for thieves, take a dynamic residential proxy and try it first:

curl "https://api.ipipgo.com/get?key=你的密钥&type=socks5"

The returned JSON with fresh proxy information, directly spelled into the Curl command can be used. It is recommended to set up a timed task to change the IP every 20 minutes, the collection success rate can be increased by 70% to 80%.

Reminder of common pitfalls

1. Certificate error: plus-kParameter Temporary Skip Validation
2. slow：换用ipipgo的TK专线，能压到200ms以内
3. abrupt disconnection: After the Curl command, add--retry 3auto-retry

What's the best way to choose a package?

- Personal small projects: dynamic standard edition, $7.67/GB enough for a month
- Enterprise-level acquisition: directly on the enterprise version of the dynamic residential, 9.47 yuan / GB with exclusive channel
- Fixed business needs: static residential IP is the most stable, suitable for long-term hang-up tasks
