一、基本訴求

能夠通過調用阿裡達摩院視覺平台提供的API來識别出二代身份證關鍵字段内容，關鍵字段包括：姓名、性别、民族、身份證号、出生日期、位址資訊、有效起始時間、簽發機關，同時可輸出身份證區域位置和人臉位置資訊。

二、項目預覽

1.進入頁面

2.上傳身份證照片資訊界面。

3.識别之後的頁面

4.源碼展示

三、前期準備

1.檢視官方說明文檔

進入阿裡達摩院視覺識别平台（

https://vision.aliyun.com/

），選擇能力廣場>文字識别>身份證識别。

2.檢視SDK執行個體文檔

3.擷取OCR的SDK的Maven坐标（Java）

傳送門

通過文字識别中檢視産品文檔，得知SDK支援包括Java、Java（本地接入）、Python、Node.js、PHP四種常用語言。通過檢索Java（支援本地上傳）的SDK，擷取OCR的Maven代碼（version=1.0.3）:

<artifactId>ocr</artifactId>
<version>1.0.3</version>

四、架構分析

建立Springboot項目，Application為啟動類；Controller為控制器層，負責模闆的渲染和路由等；Ocrservice負責通過SDK調用視覺識别的能力。上傳表單隻允許字尾為.jpg，.jpeg，.png的檔案，且不為空。

1.輸入限制：

圖檔格式：JPEG、JPG、PNG、BMP、GIF。
圖像大小：圖像大小不超過3M。
圖像分辨率：不限制圖檔分辨率，但圖檔分辨率太高可能會導緻API識别逾時，逾時時間為5秒。
URL位址中不能包含中文字元。

五、示例代碼

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.profile.DefaultProfile;
import com.google.gson.Gson;
import java.util.*;
import com.aliyuncs.ocr.model.v20191230.*;

public class RecognizeIdentityCard {

public static void main(String[] args) {
    DefaultProfile profile = DefaultProfile.getProfile("cn-shanghai", "<accessKeyId>", "<accessSecret>");
    IAcsClient client = new DefaultAcsClient(profile);

    RecognizeIdentityCardRequest request = new RecognizeIdentityCardRequest();
    request.setRegionId("cn-shanghai");
    request.setSide("face");

    try {
        RecognizeIdentityCardResponse response = client.getAcsResponse(request);
        System.out.println(new Gson().toJson(response));
    } catch (ServerException e) {
        e.printStackTrace();
    } catch (ClientException e) {
        System.out.println("ErrCode:" + e.getErrCode());
        System.out.println("ErrMsg:" + e.getErrMsg());
        System.out.println("RequestId:" + e.getRequestId());
    }

}
}

代碼是Java的srping-boot項目

六、python代碼

1.準備工作

在安裝和使用阿裡雲SDK前，確定已經注冊阿裡雲賬号并生成通路密鑰（AccessKey）。

2.安裝Python SDK核心庫。

該SDK包為阿裡雲Java核心庫，無論使用哪個産品的SDK，都必須先#

3.安裝該核心庫。

使用依賴包工具安裝（推薦）。

4.執行如下指令，安裝阿裡雲SDK核心庫。

pip install aliyun-python-sdk-core

5.自行下載下傳安裝：使用git clone或其它方式從GitHub下載下傳aliyun-python-sdk-core并自行添加解決方案。

6.安裝視覺智能API相關服務Python SDK。

7.執行以下指令，安裝需要的SDK包。

僅安裝所需要的SDK包即可。
