android studio封装wap,Android studio 封装POST请求

要封装一个POST请求，你可以使用Android的HttpURLConnection类。以下是一个简单的示例，演示如何使用HttpURLConnection进行POST请求：

public static String sendPostRequest(String url, String postData) {
    try {
        URL requestUrl = new URL(url);
        HttpURLConnection connection = (HttpURLConnection) requestUrl.openConnection();
        connection.setRequestMethod("POST");
        connection.setDoOutput(true);
        connection.setDoInput(true);
        connection.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
        connection.setRequestProperty("Accept", "application/json");
 
        OutputStream outputStream = connection.getOutputStream();
        outputStream.write(postData.getBytes());
        outputStream.flush();
        outputStream.close();
 
        InputStream inputStream = connection.getInputStream();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
        String line;
        StringBuilder response = new StringBuilder();
        while ((line = bufferedReader.readLine()) != null) {
            response.append(line);
        }
        bufferedReader.close();
        inputStream.close();
        connection.disconnect();
        return response.toString();
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

这个方法将使用HttpURLConnection类来发送POST请求。它将接受URL和POST数据作为参数，并返回响应字符串。在这个例子中，POST数据是一个JSON字符串，并且Content-Type和Accept头部设置为application/json。你可以根据你的需要修改这些设置。
