Xiaobian to share with you how to use reptile agents, I believe most people do not know how to use, so share this article for your reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

In daily web work, many web workers need to use proxy IP to help them complete tasks, such as general crawler work, marketing posts, web voting, effect addition, etc. Some people use third-party tools, some people write their own program code, call it automatically through the docking application program interface, get the IP, and then finish the work.

When using proxy IP to work, you often encounter problems such as software does not work properly, or prompts that proxy IP is completely invalid, or returns empty results after code runs. Such prompt results often make people do not know where the problem is, and they do not know where to start to solve the problem.

Many friends are more anxious, once they can not use it, they believe that there is a problem with the proxy IP, so they change one to continue to use it, and the result is still the same. Encounter this kind of problem, don't rush, find out the root cause first, and then solve it.

1. API extraction link is normal, proxy IP can be extracted normally, and the first step of many software settings is incorrect.

IP can not be extracted at all, or API return format does not meet the requirements, there are many friends of the code processing IP separation is not correct, there have been several friends, each time the use of proxy IP is the first success, later all use failed, after repeated inspection only to find that the separation processing is not correct.

So how do you determine if there is a problem with API extraction links? In fact, copy the API extraction link to the browser bar and enter to open, you can see the results: ① Unable to open the webpage, API problems;② Return IP normally, check whether the format meets the requirements;③ Other reasons cause the webpage cannot be returned normally, such as lack of parameters, or extraction speed is too fast.

2. Whether the IP authorization of the agent is correct, many paid agents now need authorization to use IP, which is relatively safe.

At present, there are three main authorization methods: ① white list;② username + password;3.1 and 2 support, can be switched. If the API cannot extract the IP usage proxy, it needs to check the authorization, for example, whether the fixed proxy terminal IP is bound in IP whitelist mode, whether there is username + password authorization in username + password mode, and whether there is confusion in both modes.

So, how do you judge authorization errors? It's actually very simple: log in directly to the proxy IP website administration background; set up the proxy IP test in the browser. For IP of fixed terminal, IP whitelist authorization mode or user name + password authorization mode is adopted. After the IP of the proxy is set in the browser, a username + password dialog box pops up, asking for a username and password;

Whether the anti-crawling strategy is correct is a frequently encountered problem. Obviously, everything is set up, the code is correct, but the access fails, or the success rate is very low, some of the previous access is successful, and suddenly one day the access fails, or fails. The first reaction of many friends is that the agent IP quality is very poor, declining, and quickly replace the agent IP service provider.

Is there really a problem with agent IP? It can actually be checked by accessing the target website via the browser with the proxy IP set. If the browser access is successful and the software or program code does not run successfully, it is likely that there is an anti-crawler policy issue and may need to be upgraded. The anti-crawling strategy will also be upgraded at this time.

The above is "how to use reptile agent" all the content of this article, thank you for reading! I believe that everyone has a certain understanding, hope to share the content to help everyone, if you still want to learn more knowledge, welcome to pay attention to the industry information channel!
