Web developers must not have dealt with Curl, this thing is like a universal download tool. However, recently there are always brothers asked me: why use Curl file always stuck into a slide show? Today we will nag how to Curl装个代理ip--Proxy IP This is a good trick.

Why do I need a proxy for Curl?

举个栗子，你从美国服务器拖文件，可能比蜗牛还慢。这时候要是用个本地代理，就像给下载通道铺了条高速路。特别是用ipipgo这种专业代理服务，节点多得像芝麻，随便挑个近的用，速度直接起飞。

 Basic download commands (turtle version)
curl -O https://example.com/bigfile.zip

 Open proxy pose (rocket version)
curl -x http://username:password@ipipgo-node1:8080 -O https://example.com/bigfile.zip

How do the proxy parameters play out?

Remember this universal formula:-x protocol://account:password@address:portThe ipipgo users just copy the parameters directly in the backend, their formatting is neat and clear:

QA First Aid Kit

Q: What should I do if I can't connect to the agent all the time?
A: First check the four elements (protocol/account/password/port), and then use telnet to measure the port pass or fail. ipipgo has real-time node status in the background, pick the green marked with.

Q: The download speed is not as good as not using a proxy?
A: eighty percent of the node selection is far, in ipipgo console to change the node of the same geographical area. For example, you under the U.S. resources to choose their North American nodes, do not let the data around the world to sneak around.

Q: How to switch proxy nodes automatically?
A：写个shell脚本轮询ipipgo的API，他们家的节点列表每5分钟更新一次，挑最低的用。

Why do you recommend ipipgo?

The agency pool for this one is deep enough that there are worldwide2000+A node squatting. The most tawdry is that there is an exclusive download optimization channel, the actual test 1G file can be more than 3 times faster than ordinary agents. New users to send 5G flow trial, registration code loseCURL2024And whoring 1G more.

Lastly, the use of proxy is not metaphysics, the key to choose the right service provider. Before the use of free proxy was pitched miserable, either the speed of pull crotch, or use two days on the road. Since I switched to ipipgo, the command line has never reported a 407 error!
