解決方案

OpenFeign調用接口?

@FeignClient(name="OCRService", url="127.0.0.1:8866") public interface IOCRService {@RequestMapping(value = "/predict/ocr_system",method = RequestMethod.POST)Object ocr(ImageDTO images); }

接口參數DTO封裝?

@Data public class ImageDTO {private List<String> images; }

?Controller

@RestController public class OCRController {private final IOCRService iocrService;public OCRController(IOCRService iocrService) {this.iocrService = iocrService;}@RequestMapping(value = "/ocr",method = {RequestMethod.POST})public Object ocr(MultipartFile[] file){try {String s =ImageBase64Encoder.encode(file[0].getInputStream());List<String> list = new ArrayList<>();list.add(s);ImageDTO dto= new ImageDTO();dto.setImages(list);return iocrService.ocr(dto);} catch (IOException e) {e.printStackTrace();}return null;} }

工具類：

import cn.hutool.core.codec.Base64Encoder;import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStream; import java.util.Objects;/*** 圖片Base64編碼*/ public class ImageBase64Encoder {/*** 將圖片轉為Base64編碼字符串* @param imgPath 圖片路徑* @return Base64編碼字符串*/public static String encode(String imgPath) throws FileNotFoundException {return encode(new FileInputStream(imgPath));}/*** 將圖片轉為Base64編碼字符串* @param in 圖片輸入流* @return Base64編碼字符串*/public static String encode(InputStream in) {byte[] data = null;// 讀取圖片字節數組try {data = new byte[in.available()];int res = in.read(data);in.close();} catch (IOException e) {e.printStackTrace();}/**對字節數組Base64編碼*返回Base64編碼過的字節數組字符串;*/return Base64Encoder.encode(Objects.requireNonNull(data));}}
