微信小程序发布需要校验敏感信息(内容、图片)-Java后端实现


微信官方文档(内容安全接口开发文档): https://mp.weixin.qq.com/cgi-bin/announce?action=getannouncement&key=11522142966rk3L2&version=1&lang=zh_CN&platform=2

前端只需要将图片和内容传过来即可

pom依赖

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是什么就不用我多少了吧

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) {
        System.out.println(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
