Methods to implement ID card OCR recognition: 1. Apply to open the ID card OCR recognition interface and obtain the API request KEY; 2. Call the interface API through "function juhecurl($url,$params=false,$ispost =0){...}", process the data and return the result; 3. Get the content returned by the interface and parse it into an array using json_decode(); 4. Print the return result.
