Android如何用阿里云的API进行身份证识别

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() {

                        }
                    });
                }
            }
            @Override
            public void onException(ApiInvokeException e) {
                // 处理异常
                LoadingUtil.dismiss();
                runOnUiThread(new Runnable() {

                    }
                });

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="" />
