Java调用百度OCR实现图片文字识别

1.这是从本地上传图片，本质是将上传的图片转换为base64后进行解析

首先导入pom依赖

 <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>okhttp</artifactId>
            <version>4.9.0</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>2.0.13</version>
        </dependency>

接口实现

@PostMapping("/recognize-img")
    @Operation(summary = "图片文字识别",description = "图片识别")
    public String recognizeImage(@RequestParam("file") MultipartFile file) {
   
        try {
   
            // 将文件转换为 Base64 编码并进行 OCR 识别
            String base64Image = baiduOcrService.convertToBase64(file,true);
            return baiduOcrService.recognizeImage(base64Image);
        } catch (IOException e) {
   
            e.printStackTrace();
            return "Error occurred while recognizing image.";
        }
    }

这是OCR的实现过程

package com.jt.console.service.impl;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.jt.common.beans.ServiceAssert;
import okhttp3.*;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;

import java.io.IOException;
import java.net.URLEncoder;
import java.util.Base64;
import java.util.List;
import java.util.Arrays;

/**

@Service("baiduOcrServiceImpl")

    @Value("${baidu.ocr.apiKey}")
    private String API_KEY;  // 客户端id

    @Value("${baidu.ocr.secretKey}")
    private String SECRET_KEY; // 客户端秘钥

    // 支持的图片格式列表
    private static final List<
