java docking proxy ip: Java language proxy ip integration tutorial

Hands-on teaching you to install proxy IP in Java

Brothers engaged in network development understand that the proxy IP is like wearing a vest to the program, especially when doing data collection, automated testing of these activities. Today we will take Java to say things, teach you how to ipipgo proxy IP loaded into the project, to ensure that you can get started after reading.

First, proxy IP in the end what is the use

For example, if you write a script that automatically registers accounts, and if you don't change the IP, you will be blocked by the website in minutes. This is where a proxy IP is aA shifty middleman.The IP pool at ipipgo's house is ridiculously large, with carrier resources in over 200 countries worldwide, so there's no fear of being blocked.

Second, Java docking triple axe

Here are two recommended common poses, both battle-tested:

// Method 1: HttpClient sets up the proxy
CloseableHttpClient client = HttpClients.custom()
    .setProxy(new HttpHost("proxy.ipipgo.com", 30001))
    .build();

// Method 2: OkHttp Configuration Proxy
OkHttpClient client = new OkHttpClient.Builder()
    .proxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.ipipgo.com", 30001)))
    .build();

Note that the port number depends on the specific package, http protocol with 30001, https with 30002, socks5 go 30003. if you can't figure it out, go directly to the backend of ipipgo to check the documentation.

III. Guide to avoiding pitfalls in actual combat

Newbies often fall into these potholes:

Fourth, how to choose packages do not spend money in vain

Comparison of the three ipipgo pawn packages:

• Dynamic residential (standard): Suitable for small-scale crawlers, more than 7 dollars 1G traffic is enough
• Dynamic Residential (Business): a must for high concurrency, with a failure retry mechanism
• Static homes: Long-term mission-specific, 35 bucks a month doesn't hurt!

V. QA time for veteran drivers

Q: What should I do if my proxy IP suddenly fails?
A: the first call ipipgo replacement interface, if it does not work to find customer service to technical support, their response speed is quite fast!

Q: The test environment works, but it reports errors when I go live?
A: 80% of the production environment IP did not add a whitelist, go to the console to the server public IP fill in the

Q: What should I do if the latency of the overseas agent is too high?
A: On their cross-border dedicated line, go to the enterprise bandwidth, much more stable than ordinary lines

Finally, a hidden trick: you can use ipipgo's client tool to generate the configuration code directly, without having to knock it out by hand. You can download their SDK package from the user center, and there are even sample projects in it, which saves you a lot of time. If you have any problems, remember that their techs are online 24 hours a day, so don't be hard on yourself.
