如何使用 Java 发送帖子？

我正在使用 selenium 和 java 对 Web 应用程序运行一些自动化测试。我的 java 代码的一部分，我想将带有 post 数据电子邮件的 http post 请求发送到 php 页面。

帖子数据应如下所示“emails=username@domain.com”

出于某种原因，我似乎无法让它工作，我觉得代码是正确的，但想也许更多的眼睛看看它，可以帮助我确定问题

它编译并运行，但它似乎没有将发布数据发送到 php 文件，就是它的样子。

那么有没有办法将它确切发送到 php 文件的内容输出？

而且，有没有办法从服务器返回消息？像“无效请求”或成功之类的。

而且我不确定代码中缺少什么，如果我在完成正确的 POST 方面缺少任何内容。：

package drtest;

//for selenium each part of the test
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class devicereplication extends SeleneseTestBase {
       public Selenium selenium;

       @BeforeMethod // this part of the code points to selenium server and launches the web browser
       public void beforeMethod() {
             selenium = new DefaultSelenium("localhost", 4444, "firefox",
                           "https://example.com");
             selenium.start();
       }


       @Test // this part of the code is the actual test being run in both java and selenium
       public void testme() {

        //login steps
        selenium.open("/dashboard/login/");
        selenium.click("id=email");
        selenium.type("id=email", "username@domain.com");
        selenium.type("id=pass", "strongpassword");
        selenium.click("id=submitInfo");
        selenium.waitForPageToLoad("30000");

        // deploy agent steps
        selenium.open("/dashboard/");
        selenium.click("link=Deployment");
        selenium.click("link=Deploy Agents");
        selenium.waitForPageToLoad("90000");

        try {

        int userCount = 5; // how many automation users in the db you are adding a device to.
        int counter = 1;
        String emailDomain = "@domain.com";
        String userName = "username";

        for (;counter <= userCount; counter ++) //this loop adds incremental values to each e-mail/username combo.
        {
        String combinedEmail = (userName+counter+emailDomain); //turns the email name into a string that can be looped.


        String request = "https://examples.com/example/example.php";
        URL url = new URL(request); //requests url

        String param=URLEncoder.encode(combinedEmail, "UTF-8");

            HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 

            connection.setDoOutput(true);
            connection.setDoInput(true);
            connection.setInstanceFollowRedirects(false); 
            connection.setRequestMethod("POST");

        //  connection.setRequestProperty("Content-Length", "344");
            connection.setUseCaches(false);


                  DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
                  wr.writeBytes(param);
                  wr.flush();
                  wr.close();
                  connection.disconnect();
        }

        } catch(MalformedURLException ex) {
                    System.out.println( ex.getMessage() );
                } catch(IOException ex){
                    System.out.println( ex.getMessage() );
                } 
}
@AfterMethod
       public void afterMethod() {
             //selenium.stop();
       }

您需要获得实际响应才能获得实际连接。类似的东西connection.getResponseCode()。

另外，放弃 DataOutputStream，只需使用：

              OutputStream out = connection.getOutputStream();
              out.write(param.getBytes("UTF-8"));
              out.flush();
              out.close();

connection在对响应代码进行任何验证之前，您正在取消连接。尝试以前做这样的事情disconnect()

int rc = connection.getResponseCode();
if(rc==200){
   //Success
} else if(rc==401) {
   System.out.println("http response code error: "+rc);
} else if(rc==404){
   //Not Found  
}

那应该完成你的测试。
