What should I do if the WeChat official account personal subscription account sharing card display fails?

Guide to troubleshooting failure of WeChat public account sharing

Recently, some developers have reported that the WeChat sharing function of personal subscription accounts is abnormal: the new website sharing card cannot display pictures and descriptions normally, while the old website is running normally. This article will address this issue, analyze possible causes and provide solutions.

The developer has confirmed that access_token, ticket and signature are obtained and calculated correctly, and the JS security domain name has also been correctly configured. The old website sharing card displays normally, which means that the problem is not that the core sharing function is invalid, but that the card information is missing.

The following aspects may cause problems:

1. Exact match of JS secure domain names: Please ensure that the configuration of JS secure domain name is exactly the same as the actual domain name. For example, www.example.com does not match example.com or m.example.com . When using subdomain names, all relevant subdomain names need to be added to the JS security domain name list.

2. Sharing parameters integrity: The WeChat sharing interface needs to pass in title , desc , link , imgUrl and other parameters. Please carefully check the settings of these parameters to ensure that imgUrl points to valid images and that the image size and format comply with WeChat specifications. Missing or incorrect parameters will cause incomplete card information.

3. WeChat cache interference: WeChat client cache may cause the new configuration information to fail to take effect immediately. It is recommended to clear the WeChat cache or use other WeChat accounts to test.

4. Multi-domain name support: One official account can configure multiple JS security domain names, not only one root domain name.

Solution:

It is recommended that developers check the above points in turn: carefully check the sharing interface parameters, JS security domain name configuration, and clear the WeChat cache. Through system troubleshooting, you can find the root cause of the missing information on sharing cards and restore the normal sharing function.
