即时通信IM，服务端导入单个帐号v4/im_open_login_svc/account_import接口的调用

代码如下：

// 生成IM用户接口
private final static String URL = "https://console.tim.qq.com/v4/im_open_login_svc/account_import?sdkappid=XXXXXXX&identifier=XXXXXX&usersig=XXXXXXXXX&random=4192147295&contenttype=json";

解析：
生成usersig见接口文档地址：https://cloud.tencent.com/document/product/269/32688
这个我以后会在文章中补上，用代码的方式生成usersig。

好了，接下来就是正儿八经的生成用户的代码了：

/**
	 * 生成IM用户
	 * @param args
	 * @throws IOException
	 * username 你要生成的用户名
	 * headurl 你用户的头像路径
	 */
	public static String imUser(String username,String headurl) 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();
		obj.element("Identifier", username);
		obj.element("Nick", username);
		obj.element("FaceUrl", headurl);
		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();
		String ActionStatus = jObject.get("ActionStatus").getAsString();
		System.out.println(ActionStatus);
		return ActionStatus;
	}

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
	}

测试

public static void main(String[] args) throws IOException {
        // 要导入的用户名
		String username = "zx0062";
		// 你想要的图片路径
		String headurl = "http://********:8088/*******/webpage/auto/userimg/216140998.jpeg";
		imUser(username, headurl);
	}

运行
