testng发送https的post请求

要发送HTTPS的POST请求，可以使用Java的HttpURLConnection类。下面是一个示例代码，可以根据自己的需要进行修改：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;

import org.testng.annotations.Test;

public class HttpsPostTest {
    
    @Test
    public void testHttpsPost() throws Exception {
        String url = "https://example.com/api";
        String data = "param1=value1&param2=value2";
        
        URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("POST");
        con.setRequestProperty("User-Agent", "Mozilla/5.0");
        con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
        con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        con.setDoOutput(true);
        OutputStreamWriter wr = new OutputStreamWriter(con.getOutputStream());
        wr.write(data);
        wr.flush();
        
        int responseCode = con.getResponseCode();
        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();
        
        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();
        
        System.out.println("Response Code : " + responseCode);
        System.out.println("Response Content : " + response.toString());
    }
}

在上面的示例代码中，我们首先设置要请求的URL和POST数据。然后创建一个URL对象和HttpURLConnection对象。设置请求方法为POST，设置请求属性，将输出设置为true。然后将POST数据写入输出流，并刷新输出流。最后获取响应代码和响应内容。
