Baidu AI face recognition interface test

I was working on a project recently, and I just achieved face recognition. I was afraid that I would forget how to call it in the future. I will record here.

First of all, we have already done the configuration of Baidu interface by default (application application, generated AK, SK, etc.)

Not much to say, go directly to the code

      The code given on the official website is identified by the FaceToken identification code. In this program, I changed this method to Base64 code. I personally feel that the Base64 code is more usable.

The tools used by Baidu API are included in the comments and can be downloaded directly from the website

Next, I will show you the directory structure for easy understanding

If you encounter any problems, you can leave a message below and I will discuss with you

Part of the results after successful display

Secondly, calling the api requires designing meaven related operations. Since it is late at night when this document is uploaded, the author will update it as necessary. You can pay attention to the subsequent updates. If this document helps you, you may wish to give this document a thumbs up. Let more people see it! ^_^
