Http接口测试—客户端的编写

public class TestClient {

	public static void main(String[]agrs){
		TestClient a=new TestClient();
		a.client();

	public void client(){

		try {

			String data="hello测试";
			URL serverUrl= new URL("http://localhost:8090/lctest/TestServer");
			URLConnection uct= serverUrl.openConnection();
			HttpURLConnection hutc=(HttpURLConnection)uct;

			// 设置报文参数
			hutc.setRequestMethod("POST");

			// 设置是否向httpUrlConnection输出，因为这个是post请求，参数要放在 http正文内，因此需要设为true, 默认情况下是false; 
			hutc.setDoOutput(true);

			// 设置是否从httpUrlConnection读入，默认情况下是true
			hutc.setDoInput(true);
			//hutc.setAllowUserInteraction(true);

			// 开启流，写入数据data
			OutputStream out=hutc.getOutputStream();
			out.write(data.getBytes("UTF-8"));
			out.flush();
			out.close();	

			// 获取返回的数据
			StringBuffer buffer=new StringBuffer();
