java接收接口推送_java使用httpclient调用push接口(推送云API)

Java 通过 HttpClient 调用 Push 接口（推送云 API）可以使用以下代码：

import java.io.IOException;
import java.nio.charset.StandardCharsets;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;

public class PushClient {

    private static final String PUSH_URL = "https://api.push.com/v2/push";
    private static final String APP_KEY = "your app key";
    private static final String MASTER_SECRET = "your master secret";

    public static void main(String[] args) throws IOException {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost(PUSH_URL);

        // 设置请求头
        httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
        httpPost.setHeader("Authorization", "Basic " + base64Encode(APP_KEY + ":" + MASTER_SECRET));

        // 设置请求参数
        List<NameValuePair> params = new ArrayList<>();
        params.add(new BasicNameValuePair("platform", "android"));
        params.add(new BasicNameValuePair("audience", "all"));
        params.add(new BasicNameValuePair("notification", "{\"alert\":\"Hello, world!\"}"));
        httpPost.setEntity(new UrlEncodedFormEntity(params, StandardCharsets.UTF_8));

        // 发送请求并获取响应
        HttpResponse response = httpClient.execute(httpPost);
        HttpEntity entity = response.getEntity();
        String result = EntityUtils.toString(entity, StandardCharsets.UTF_8);

        // 处理响应
        System.out.println(result);

        // 关闭连接
        httpClient.close();
    }

    private static String base64Encode(String str) {
        return new String(java.util.Base64.getEncoder().encode(str.getBytes()));
    }
}

其中，`PUSH_URL` 是 Push 接口的 URL，`APP_KEY` 和 `MASTER_SECRET` 是 Push 服务的 App Key 和 Master Secret。通过设置请求头和请求参数，构造 `HttpPost` 请求对象，并发送请求获取响应，最后处理响应即可完成 Push 消息的发送。
