Java Server SDK

XuqmGroup 服务端 Java SDK，按腾讯云服务端 API 的思路封装了以下能力：

• IM 账号与登录
• 消息发送、编辑、撤回、历史查询
• 好友、黑名单、会话、群组
• Webhook、管理端操作、统计
• Push 注册与发送
• Update 版本检查、上传、发布、灰度、应用商店提审

安装

Maven 在 pom.xml 中添加：

<repository>
  <id>xuqm-nexus</id>
  <url>https://nexus.xuqinmin.com/repository/maven-public/</url>
</repository>

<dependency>
  <groupId>com.xuqm</groupId>
  <artifactId>im-sdk</artifactId>
  <version>0.1.0-SNAPSHOT</version>
</dependency>

Gradle：

repositories {
    maven { url = uri("https://nexus.xuqinmin.com/repository/maven-public/") }
}

dependencies {
    implementation("com.xuqm:im-sdk:0.1.0-SNAPSHOT")
}

---

初始化

import com.xuqm.im.sdk.XuqmImServerSdk;

XuqmImServerSdk client = XuqmImServerSdk.builder()
    .baseUrl("https://dev.xuqinmin.com")
    .appKey("your_app_key")
    .appSecret("your_app_secret")
    .build();

服务端 SDK 需要 appSecret 用于 HMAC 签名，appSecret 绝不下发到客户端。

发送消息

import com.xuqm.im.sdk.XuqmImServerSdk.ImMessage;
import com.xuqm.im.sdk.XuqmImServerSdk.SendMessageRequest;

ImMessage msg = client.sendMessage(new SendMessageRequest(
    "user_002",
    "SINGLE",
    "TEXT",
    "Hello from Java SDK!",
    null,
    null,
    null
));

System.out.println("消息已发送: " + msg.getId());

发送群消息

ImMessage msg = client.sendMessage(SendMessageRequest.builder()
    .toId("group_xxx")
    .chatType("GROUP")
    .msgType("TEXT")
    .content("大家好")
    .build());

撤回消息

client.revokeMessage("message_id");

群管理示例

import com.xuqm.im.sdk.XuqmImServerSdk.GroupView;

GroupView group = client.createGroup("项目讨论", List.of("user_001", "user_002"), "NORMAL");

client.addGroupMember("group_xxx", "user_003");
client.removeGroupMember("group_xxx", "user_003");

List<GroupView> groups = client.listGroups();

---

Push 推送

import com.xuqm.sdk.server.model.SendPushRequest;

client.sendPush(SendPushRequest.builder()
    .userId("user_001")
    .title("新消息")
    .body("你有一条未读消息")
    .payload("{\"chatId\":\"user_002\"}")
    .build());

---

错误处理

import com.xuqm.im.sdk.XuqmImServerSdk.ImSdkException;

try {
    ImMessage msg = client.sendMessage(request);
} catch (ImSdkException e) {
    System.err.printf("API 错误: status=%d, code=%d, message=%s%n",
        e.getHttpStatus(), e.getCode(), e.getMessage());
}
