This article mainly introduces the Wechat URL link unblocking of the anti-blocking principle of visit_type example analysis, the article introduced in great detail, has a certain reference value, interested friends must read!

Preface

Some time ago, 80% of the daily visits came from Wechat, and the products are in full compliance with national laws. However, the link to Wechat has been blocked twice, and each time it was blocked by Wechat, the number of page views dropped a lot. It took a lot of efforts to restore it, and it was blocked again in a few days. I really want to scold Wechat.

We have also tried to unseal the Wechat URL, and Wechat officials must ask for the "violation" to be removed, but it is difficult because we do not break the law, there is no malicious sharing, and there is no N-level distribution. In order to use it normally in the future, we finally choose the anti-blocking system provided by v94.cn.

Because of the company's business needs, recently has been looking for Wechat URL anti-blocking solution, I would like to talk about my company's products, specific products can not be disclosed. I'll post the address of practical information first.

Let me briefly simulate an example of how it jumps in Wechat:

Weibo short URL-- > short domain name URL 1mure-> short domain name URL 2mury-> short domain name URL N1mury-> short domain name URL Numb1mure-> three options to open the landing page visit_type.

At present, it supports a minimum of 5 levels and a maximum of 10 levels.

Today, I'm going to focus on the three ways to open the landing page URL of v94cn in Wechat: visit_type.

The first solution: open jump directly (this is the default scheme)

Look at the example diagram above, it is easy to understand if you open it directly. After N times of jump no, open the landing page URL directly through the 301ram 302 web page status code

The second scheme: the blocked URL restores visit_type=frame.

Literally, you can see that you are using a frame, but when the frame is opened, title is blank, and v94cn can automatically add titles, which is easier to use than your peers. And the SDK and api they provide support the addition of titles.
