使用文档中提供的相同示例代码,您所需要做的就是更改 main 方法,如下所示:
public static void main(String[] args) throws Exception{
// Create a new file object for the first file and get bytes from file
File file = new File("C:\\Users\\ihene\\Desktop\\my-photo.jpg");
byte[] buff1 = getBytesFromFile(file);
// Create a new file object for the second file and get bytes from file
File file2 = new File("C:\\Users\\ihene\\Desktop\\esan-caleb.jpg");
byte[] buff2 = getBytesFromFile(file2);
// Data needed to use the Face++ Compare API
String url = "https://api-us.faceplusplus.com/facepp/v3/compare";
HashMap<String, String> map = new HashMap<>();
HashMap<String, byte[]> byteMap = new HashMap<>();
map.put("api_key", "dam4ZdTkSsZOUAiR4oQpP3DRnjEz1fcD");
map.put("api_secret", "0MOCfpum1Lec06EMOzuJPOEa_EhM4Ttg");
byteMap.put("image_file1", buff1);
byteMap.put("image_file2", buff2);
try {
// Connecting and retrieving the JSON results
byte[] bacd = post(url, map, byteMap);
String jsonStr = new String(bacd);
// Parse the JSON and get the confidence value
JSONObject obj = new JSONObject(jsonStr);
double confidence = obj.getDouble("confidence");
System.out.println(confidence);
} catch (Exception e) {
e.printStackTrace();
}
}
只需将PATH_TO_FILE_1、PATH_TO_FILE_2、YOUR_API_KEY、 和替换YOUR_API_SECRET为适当的值即可。它应该有效。
我使用两张脸部属于同一个人的图像和另外两张不同脸部的图像测试了 API。这是我得到的前者的输出:
{"faces1": [{"face_rectangle": {"width": 156, "top": 210, "left": 142, "height": 156}, "face_token": "1ee9de6d362b0c8c1bf240a70fbf3eac"}], "faces2": [{"face_rectangle": {"width": 156, "top": 210, "left": 142, "height": 156}, "face_token": "0a7c539f3603aa744ee18c65acc224a8"}], "time_used": 531, "thresholds": {"1e-3": 62.327, "1e-5": 73.975, "1e-4": 69.101}, "confidence": 97.389, "image_id2": "Fc64vrBtETVmP2cS+BoW/Q==", "image_id1": "Fc64vrBtETVmP2cS+BoW/Q==", "request_id": "1569184566,0cc04f1a-1495-4316-928c-1efe7d6836dc"}
请注意,这里的置信度是97.389。文件称,“置信度越高,表明两张脸属于同一个人的可能性就越高。” 所以,这符合我们的预期。对于后面具有不同面孔的图像,输出如下:
{"faces1": [{"face_rectangle": {"width": 156, "top": 210, "left": 142, "height": 156}, "face_token": "c7d8561f0235a99d9b060750c7a9c3c7"}], "faces2": [{"face_rectangle": {"width": 75, "top": 44, "left": 53, "height": 75}, "face_token": "ad87092cb593128c015c2e2221b962f2"}], "time_used": 533, "thresholds": {"1e-3": 62.327, "1e-5": 73.975, "1e-4": 69.101}, "confidence": 53.993, "image_id2": "MiZOf00hrq7OmAxc3+n7sg==", "image_id1": "Fc64vrBtETVmP2cS+BoW/Q==", "request_id": "1569185082,0bfd0a0f-a376-4dac-92bd-924c34ef76ed"}
此处,置信度为53.933。
