为什么在使用 Azure 人脸 API 时，我会在 Android 中收到 URL 调用的 FileNotFoundEx

Question

这是我在Android上尝试比较两张脸是否属于同一个人的方法。我还在最后展示了我的错误代码。这与 API 有关吗？

try {
URL url = new URL("https://southeastasia.api.cognitive.microsoft.com/face/v1.0/verify?faceId1=" + face1 + "&faceId2=" + face2);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty("Ocp-Apim-Subscription-Key", "----");
try {
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
StringBuilder stringBuilder = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
stringBuilder.append(line).append("n");
}
bufferedReader.close();
getting = stringBuilder.toString();
Log.v("Gettinganswer", getting);
return  getting;
} finally {
urlConnection.disconnect();
}
}
catch(Exception e) {
Log.e("ERROR", e.getMessage(), e);
return null;
}

Answer 1

这与 API 有关吗？

根据文档，我们可以知道人脸验证API端点应该是

post https://[location].api.cognitive.microsoft.com/face/v1.0/verify

正文格式为

{
"faceId1": "xxxxxxxx",
"faceId2": "xxxxx",
}
