微信小程序發佈須要校驗敏感信息(內容、圖片)-Java後端實現

微信官方文檔（內容安全接口開發文檔）： https://mp.weixin.qq.com/cgi-bin/announce?action=getannouncement&key=11522142966rk3L2&version=1&lang=zh_CN&platform=2

前端只須要將圖片和內容傳過來便可

pom依賴

HttpClient的依賴和json轉換的依賴

<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>

封裝Vo類

用於獲取到access_token後進行轉換，access_token是什麼就不用我多少了吧

public class AccessTokenVO {
    private String access_token;
    private Integer expires_in;
    //記得給get set方法
}
