JAVA连接企业微信机器人

   public static void sendMessage(String webhookUrl, String message) throws IOException {
        URL url = new URL(webhookUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type", "application/json");
        connection.setDoOutput(true);

        String jsonPayload = "{\"msgtype\":\"text\",\"text\":{\"content\":\"" + message + "\"}}";

        try (OutputStream outputStream = connection.getOutputStream()) {
            byte[] input = jsonPayload.getBytes("utf-8");
            outputStream.write(input, 0, input.length);
        }

        int responseCode = connection.getResponseCode();
        if (responseCode != 200) {
            throw new IOException("Message sending failed with response code: " + responseCode);
        }
    }

main函数运行该方法测试

WebhookUrl是机器人的链接

message是要发出的信息

运行main函数 发送成功过
