Java 向谷歌云消息发送改装后的帖子

gcmr响应：

Main:

当我通过改造向GCM发送帖子时，它总是返回回复“400 InvalidTokenFormat”，互联网上没有文档

我在代码中做错了什么？这个响应意味着什么？

您的

服务实际是如何实现的？我看不出您是如何为
注册\u id
字段输入键名的。@ztan我编辑了问题，添加了使用“注册\u id”的主方法，首先在debug in response对象中检查您的请求url-看起来应该是基本url，/gcm/send-应该是POST批注中的字符串。但这不是你问题的根源。最可能的情况是json格式错误（HTML400就是这么解释的），所以最好用嵌套对象重写GCMRequest
public class GCMResponse {

    public String multicast_id;
    public int success;
    public int failure;
    public int canonical_ids;
    public List<GCMObject2> results;

    public class GCMObject2 {
        public int message_id;
        public int registration_id;
        public String error;
    }
}

public class GCMRequest {
    public List<String> registration_ids;
    public Map<String, String> data;

    public GCMRequest(String title, String message, String icon) {
        registration_ids = new LinkedList<>();

        data = new HashMap<>();

        data.put("title", title);
        data.put("message", message);
        data.put("icon", icon);
    }

    public void addRegId(String regId) {
        registration_ids.add(regId);
    }
}

public interface RetrofitService {
    @Headers("Content-Type: application/json")
    @POST("/")
    public GCMResponse GCMAuthorization(@Header("Authorization") String apiKey, @Body GCMRequest data);
}

private static final String GCM_SERVER_URL = "https://android.googleapis.com/gcm/send";

private static void sendWithRetrofit(String apiKey, GCMRequest gcmRequest) {
    RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint(GCM_SERVER_URL)
            .build();

    final RetrofitService service = restAdapter.create(RetrofitService.class);

    try {
        GCMResponse gcmResponse = service.GCMAuthorization("key=" + apiKey, gcmRequest);
        System.out.println(gcmResponse);
    } catch (Exception e) {

    }
