置顶本地使用hutools的http工具可以发起请求，部署到云托管后无法发起请求拿到想要的数据是咋回事？精选热门

2022-08-181157浏览问题模块：其他开发相关的问题

以下代码为在调用模板推送时获得Access-Token，若缓存存在则缓存中读，缓存过去则重新发起请求

public String getToken() {
    if (WxChatCache.AccessToken.expiration <= System.currentTimeMillis()) {
        System.out.println("开始请求获取token");
        String url = WxChatConstant.Url.ACCESS_TOKEN_URL
                .replace("APPID", wxMpProperties.getAppId())
                .replace("APPSECRET", wxMpProperties.getSecret());
        //http
        String s = HttpUtil.get(url);
        AccessTokenRespone ac  = JSONObject.parseObject(s,AccessTokenRespone.class);
        // expiration：为当前执行到此处的时间+2小时有效时间为过期时间
        WxChatCache.AccessToken.token = ac.getAccess_token();
        WxChatCache.AccessToken.expiration = System.currentTimeMillis()+7200000;
        System.out.println("已获取token:"+ac.getAccess_token()+";有效期限为："+ac.getExpires_in());
        return WxChatCache.AccessToken.token;
    }
    else {
        System.out.println("返回缓存中的token:"+ WxChatCache.AccessToken.token);
        return WxChatCache.AccessToken.token;
    }
}

本地调试时在控制台中能够输出如下结果：

OpenID:xxxxxxxx;=========;content:哈哈哈你好
返回缓存中的token：xxxxxxxxxxxxxxxx
send方法里的token：xxxxxxxxxxxxxxxx
调用的接口地址为:https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=xxxxxxxxxxxxxxxx

然后部署到云托管服务器中时，通过postman发起接口调用，主动推送消息给公众号，提示token为null，无法获取到token，以下是运行日志：
