SpringCloud 利用Feign完成Google FCM完成APP消息推送

FCM消息实体：

import java.util.Map;

@lombok.Data
@lombok.ToString
public class FcmSendReqVo {

    private Notification notification = new Notification();
    private Map data;
    private String to;

    public FcmSendReqVo(String token, String title, Map data) {
        this.to = token;
        this.notification.setTitle(title);
        this.data = data;
    }

    @lombok.Data
    private class Notification {
        private String title;
        private String body;
        private String sound = "default";
    }

}

Feign接口：

import com.nboot.push.feign.vo.FcmSendReqVo;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;

@FeignClient(name = "google-fcm", url = "https://fcm.googleapis.com")
@RequestMapping("/fcm")
public interface GoogleFcmFeign {

    /**
     * 发送
     * @param apiKey
     * @param reqVo
     * @return
     */
    @PostMapping("/send")
    String send(@RequestHeader("Authorization") String apiKey,  @RequestBody FcmSendReqVo reqVo);

}

调用：

// 谷歌推送token，需要APP端上传
String token = 'xxxxxxxxxx';
// 消息内容
String msg = "这是一条安卓推送消息";
// 组装data，自定义数据
Map data = new HashMap<>(8);
data.put("id", 123456);
data.put("type", 1);
// 执行推送
try {
    FcmSendReqVo fcmSendReqVo = new FcmSendReqVo(token, msg, data);
    log.info("Android推送开始: {}", JSON.toJSONString(fcmSendReqVo));
    String result = googleFcmFeign.send("key=" + androidApiKey, fcmSendReqVo);
    JSONObject json = JSON.parseObject(result);
    log.info("Android推送完成：success={}, failure={}, response={}", json.getString("success"), json.getString("failure"), result);
} catch (Throwable e) {
    log.error("Android推送异常", e);
}
