HttpClient的依赖和json转换的依赖

<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.54</version>
</dependency>
<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.10</version>
</dependency>

封装Vo类

用于获取到access_token后进行转换，access_token是什么就不用我多说了吧

public class AccessTokenVO {private String access_token;private Integer expires_in;//记得给get set方法
}

封装工具类

}

编写Controller层

import com.itheima.fete.utils.SenInfoCheckUtil;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;import java.io.IOException;/*** @author 漫路h* 校验内容是否敏感*/
@RestController
@RequestMapping("/check")
public class CheckController {/*** 校验内容* @param content* @return* @throws IOException*/@GetMapping("/content/{content}")public Boolean checkContent(@PathVariable String content) {String accessToken = SenInfoCheckUtil.getAccessToken();return SenInfoCheckUtil.cotentFilter(accessToken, content);}/*** 校验图片* @param multipartFile* @return*/@PostMapping("/image")public Boolean checkImage(@RequestPart(value = "file") MultipartFile multipartFile){String accessToken = SenInfoCheckUtil.getAccessToken();return SenInfoCheckUtil.imgFilter(accessToken, multipartFile);}
}

如果不明白就问，如果需要uniapp代码的kou我
