Android如何用阿里云的API进行身份证识别
2024-08-30 06:43:03
准备工作：在libs下添加 alicloud-Android-apigateway-sdk-1.0.1.jar,commons-codec-1.10-1.jar
在build.gradle添加 compile'com.squareup.okhttp3:okhttp:3.4.1'
在onCreate,或者afterViews初始化API网关
private void initGatewaySdk() {
// 初始化API网关
ApiGatewayClient.init(getApplicationContext(), false);
}
调用拍照功能
private void getPhotoCard(){
final String status = Environment.getExternalStorageState();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, CAMERA_REQUEST_CODE);
}
if (status.equals(Environment.MEDIA_MOUNTED)) {
defaultPhotoAddress = PHOTO_DIR + "/" + getPhotoName();
PreferenceUtils.modifyStringValueInPreferences(CardActivity.this, Preferences.IMAGE_3, defaultPhotoAddress);
imageUri = Uri.fromFile(new File(defaultPhotoAddress));
Intent intentPhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//action is capture
intentPhoto.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intentPhoto, CAMERA_REQUEST_CODE);
} else {
Toast.makeText(CardActivity.this, "没有sd卡", Toast.LENGTH_SHORT).show();
}
}
可以对照片进行裁剪
private void cropImageUri(Uri desUri, int outputX, int outputY, int requestCode){
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(desUri, "image/*");
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 5);
intent.putExtra("aspectY", 3);
intent.putExtra("outputX", outputX);
intent.putExtra("outputY", outputY);
intent.putExtra("scale", true);
intent.putExtra(MediaStore.EXTRA_OUTPUT, desUri);
intent.putExtra("return-data", false);
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
intent.putExtra("noFaceDetection", true);
startActivityForResult(intent, requestCode);
}
用base64上传照片
private void trygetCardNum() {
if (NetworkUtils.isConnectWithTip(this, "您未连接网络，无法获取数据")) {
LoadingUtil.show(this);
String imgBase64 = "";
try {
defaultPhotoAddress = PreferenceUtils.getStringValueInPreferences(this, Preferences.IMAGE_3);
File file = new File(defaultPhotoAddress);
byte[] content = new byte[(int) file.length()];
FileInputStream finputstream = new FileInputStream(file);
finputstream.read(content);
finputstream.close();
imgBase64 = new String(Base64.encodeBase64(content));
// imgBase64 = Base64Img.Bitmap2StrByBase64(bitmap);
if(imgBase64!=null||!imgBase64.equals("")){
PreferenceUtils.modifyStringValueInPreferences(CardActivity.this, Preferences.IMAGE_3, null);
}
} catch (IOException e) {
e.printStackTrace();
return;
}
// 获取服务
RpcService rpcService = ApiGatewayClient.getRpcService();
final ApiRequest apiRequest = new ApiRequest();
// 设置请求地址、Path及Method
apiRequest.setAddress("https://dm-51.data.aliyun.com");
apiRequest.setPath("/rest/160601/ocr/ocr_idcard.json");
apiRequest.setMethod(HttpMethod.POST);
// 按照文档设置二进制形式Body，支持设置Query参数、Header参数、Form形式Body
apiRequest.setStringBody("{\"inputs\":[{\"image\":{\"dataType\":50,\"dataValue\":\""+imgBase64+"\"},\"configure\":{\"dataType\":50,\"dataValue\":\"{\\\"side\\\":\\\"face\\\"}\"}}]}");
// 设置支持自签等形式的证书，如果服务端证书合法请勿设置该值，仅在开发测试或者非常规场景下设置。
apiRequest.setTrustServerCertificate(true);
// 设置超时
apiRequest.setTimeout(10000);
rpcService.call(apiRequest, new ApiResponseCallback() {
@Override
public void onSuccess(ApiResponse apiResponse) {
// 处理apiResponse
LoadingUtil.dismiss();
String s = apiResponse.getStringBody();
NumBean result = JSONObject.parseObject(s, NumBean.class);
String dataValue = result.getOutputs().get(0).getOutputValue().getDataValue();
DataValueBean dataValueBean = JSONObject.parseObject(dataValue, DataValueBean.class);
Number = dataValueBean.getNum();
name = dataValueBean.getName();
address = dataValueBean.getAddress();
birth = dataValueBean.getBirth();
nationality = dataValueBean.getNationality();
sex = dataValueBean.getSex();
if(dataValueBean.getError_msg()==null){
runOnUiThread(new Runnable() {
public void run() {
if(Number == null||Number.equals("")||name == null||name.equals("")||address == null||address.equals("")||birth == null||birth.equals("")||sex == null||sex.equals("")){
Toast.makeText(CardActivity.this, "扫描失败，请重试", Toast.LENGTH_LONG).show();
}else {
//扫描成功
}
}
});
}else {
errString = dataValueBean.getError_msg();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(CardActivity.this, "扫描失败，请重试", Toast.LENGTH_LONG).show();
}
});
}
}
@Override
public void onException(ApiInvokeException e) {
// 处理异常
LoadingUtil.dismiss();
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(CardActivity.this, "扫描失败，请重试", Toast.LENGTH_LONG).show();
}
});
}
});
}
}
附：
public class NumBean implements Serializable{
private List<OutputsBean> outputs;
public List<OutputsBean> getOutputs() {
return outputs;
}
public void setOutputs(List<OutputsBean> outputs) {
this.outputs = outputs;
}
public static class OutputsBean {
private String outputLabel;
private OutputMultiBean outputMulti;
private OutputValueBean outputValue;
public String getOutputLabel() {
return outputLabel;
}
public void setOutputLabel(String outputLabel) {
this.outputLabel = outputLabel;
}
public OutputMultiBean getOutputMulti() {
return outputMulti;
}
public void setOutputMulti(OutputMultiBean outputMulti) {
this.outputMulti = outputMulti;
}
public OutputValueBean getOutputValue() {
return outputValue;
}
public void setOutputValue(OutputValueBean outputValue) {
this.outputValue = outputValue;
}
public static class OutputMultiBean {
}
public static class OutputValueBean {
private int dataType;
private String dataValue;
public int getDataType() {
return dataType;
}
public void setDataType(int dataType) {
this.dataType = dataType;
}
public String getDataValue() {
return dataValue;
}
public void setDataValue(String dataValue) {
this.dataValue = dataValue;
}
}
}
}
public class DataValueBean implements Serializable{
private String address;
private String birth;
private String config_str;
private String error_msg;
private String name;
private String nationality;
private String num;
private String request_id;
private String sex;
private boolean success;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getBirth() {
return birth;
}
public void setBirth(String birth) {
this.birth = birth;
}
public String getConfig_str() {
return config_str;
}
public void setConfig_str(String config_str) {
this.config_str = config_str;
}
public String getError_msg() {
return error_msg;
}
public void setError_msg(String error_msg) {
this.error_msg = error_msg;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNationality() {
return nationality;
}
public void setNationality(String nationality) {
this.nationality = nationality;
}
public String getNum() {
return num;
}
public void setNum(String num) {
this.num = num;
}
public String getRequest_id() {
return request_id;
}
public void setRequest_id(String request_id) {
this.request_id = request_id;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public boolean isSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}
}
在AndroidManifest.xml下添加 Appkey
<meta-data android:name="com.alibaba.apigateway.appKey" android:value="" />
<meta-data android:name="com.alibaba.apigateway.appSecret" android:value="" />
