如何用阿里云的API进行身份证识别
以下内容属于引用复制，但可以回复你的问题：
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
<meta-data android:name="com.alibaba.apigateway.appKey" android:value="" />
<meta-data android:name="com.alibaba.apigateway.appSecret" android:value="" />
阿里云计算有限公司为什么要身份证正反面照片和本人手持照?有什么用吗
作为身份证识别sdk开发者，个人认为是通过调用api接口使用的，作为自己项目功能使用
阿里云ocr身份证拍照不能识别
接入API.做的项目里面涉及到了身份证识别输入的真实姓名与身份证号码是否匹配功能，于是在阿里云接了智能身份证OCR文字识别API，登录阿里云找到对应的产品。
阿里云api怎么使用
阿里云有很多服务，每个服务都有不同的api，基本上都是用http的方式(get/post)来调用的，不过自己调的话很麻烦，你可以进去你需要的服务的文档中心那找一下 PHP 对应的 SDK
