接口参数说明:
代码如下:
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;
import net.sf.json.JSONObject;
public class IMGroupUtil {
// 模拟向腾讯云发送接口
// 接口
// sdkappid 自己应用中填写相对应的
// 管理员用户identifier
// usersig 自行生成根据管理员用户
private final static String URL = "https://console.tim.qq.com/v4/group_open_http_svc/create_group?sdkappid=*******&identifier=ceshi&usersig=*****&random=4192147295&contenttype=json";
/**
* @param args
* @throws IOException
*/
public static String imGroup(String ownerAccount,String groupName,String maxMemberCount) throws IOException {
// TODO Auto-generated method stub
// 连接服务器
HttpURLConnection connection = connection(URL);
DataOutputStream out = new DataOutputStream(connection.getOutputStream());
JSONObject obj = new JSONObject();
/*{
"Owner_Account": "leckie", // 群主的 UserId(选填)
"Type": "Public", // 群组类型:Private/Public/ChatRoom/AVChatRoom/BChatRoom(必填)
"Name": "TestGroup", // 群名称(必填)
"Introduction": "This is group Introduction", // 群简介(选填)
"Notification": "This is group Notification", // 群公告(选填)
"FaceUrl": "http://this.is.face.url", // 群头像 URL(选填)
"MaxMemberCount": 500, // 最大群成员数量(选填)
"ApplyJoinOption": "FreeAccess" // 申请加群处理方式(选填)
}*/
obj.element("Owner_Account", ownerAccount);// 群主的 UserId(选填)
obj.element("Type", "ChatRoom");
obj.element("Name", groupName);
//obj.element("Introduction", introduction);
//obj.element("Notification", notification);
//obj.element("FaceUrl", "");
obj.element("MaxMemberCount", maxMemberCount);
//obj.element("ApplyJoinOption", "");
System.out.println(obj.toString());
// 向腾讯请求传入编码为UTF-8格式的json数据
out.write(obj.toString().getBytes("UTF-8"));
out.flush();
out.close();
// 获得服务器返回的结果
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String lines;
StringBuffer sb = new StringBuffer("");
while ((lines = reader.readLine()) != null) {
lines = new String(lines.getBytes(), "utf-8");
sb.append(lines);
}
reader.close();
System.out.println(sb);
// 将BufferedReader转换为String 类型,然后进行解析
String returnString = sb.toString();
JsonObject jObject =new JsonParser().parse(returnString).getAsJsonObject();
int ErrorCode = jObject.get("ErrorCode").getAsInt();
String GroupId = "";
if(ErrorCode==0){
GroupId = jObject.get("GroupId").getAsString();
}else{
GroupId = "出错了";
}
return GroupId;
}
public static HttpURLConnection connection(String URL) throws IOException {
URL url = new URL(URL);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setUseCaches(false);
connection.setInstanceFollowRedirects(true);
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=UTF-8");
connection.connect();
return connection;
// TODO Auto-generated method stub
}
}
调用方式:
public static void main(String[] args) {
String ownerAccount = "zx05569";// ownerAccount 群主UserId
String groupName = "测试";// 群名称(必填)
String maxMemberCount = "500";// 最大群成员数量(选填)
try {
IMGroupUtil.imGroup(ownerAccount, groupName, maxMemberCount);
} catch (IOException e) {
e.printStackTrace();
}
}
注意点:1.管理员用户从哪儿来?可在应用中自行添加管理员,如下:
2.生成usersig ,可查看:即时通信IM,服务端java代码生成签名usersig
