步骤

步骤	操作
1	获取access_token
2	组装模板消息
3	发送模板消息

代码示例

步骤1：获取access_token

// 发送HTTP GET请求获取access_token
String url = "
HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
connection.setRequestMethod("GET");

// 获取返回的结果
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String access_token = reader.readLine();
reader.close();

步骤2：组装模板消息

// 组装模板消息的数据
String template = "{\n" +
    "    \"touser\": \"OPENID\",\n" +
    "    \"template_id\": \"TEMPLATE_ID\",\n" +
    "    \"data\": {\n" +
    "        \"first\": {\n" +
    "            \"value\": \"Hello\",\n" +
    "            \"color\": \"#173177\"\n" +
    "        },\n" +
    "        \"keyword1\": {\n" +
    "            \"value\": \"World\",\n" +
    "            \"color\": \"#173177\"\n" +
    "        }\n" +
    "    }\n" +
    "}";

步骤3：发送模板消息

// 发送HTTP POST请求发送模板消息
String url = " + access_token;
HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);

// 发送模板消息数据
OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
writer.write(template);
writer.flush();
writer.close();

// 获取返回的结果
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String result = reader.readLine();
reader.close();
