調用阿裡雲OCR接口識别身份證和戶口本

一、controller層代碼

package com.wy.gcserver.ocr.controller;

import com.wy.gcserver.ocr.service.AliyunApiOcrService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@Api(tags = "AliyunApiOcrController", description = "阿裡雲API調用OCR識别")
@RestController
@RequestMapping(value = "/aliyun/api/ocr")
public class AliyunApiOcrController {

    @Autowired
    private AliyunApiOcrService aliyunApiOcrService;

    /**

     *
     * @param job
     * @param image
     * @return
     */
    @ApiOperation("擷取身份證OCR識别資訊")
    @RequestMapping(value = "/getIdcardOcr",method = RequestMethod.POST)
    public String getIdcardOcr(@RequestParam(value = "job") @ApiParam("正反面辨別：face-人臉面/back-國徽面") String job,
                               @RequestParam(value = "image") @ApiParam("圖檔base64") String image){
        String result = aliyunApiOcrService.getIdcardOcr(job, image);

        return result;
    }

    /**

     * @return
     */
    @ApiOperation("擷取戶口本OCR識别資訊")
    @RequestMapping(value = "/getHouseholdOcr",method = RequestMethod.POST)
    public String getHouseholdOcr(@RequestParam(value = "image") @ApiParam("圖檔base64") String image){
