用代码详细说明用eclipse做一个网页,输入车牌号,显示金额在页面上,接口如下:http://10.198.8.102:8081/TruckParkTime?Token=Parking2023&TruckNo=粤AFN8885;返回结果如下"{\"Code\": \"0\",\"ErrorMsg\": \"0\",\"TruckNo\": \"粤AFN8885\",\"Intime\": \"2023/7/18 8:36:01\",\"ParkTime\": \"27\",\"Money\": \"0\"}"

基于SSM的咖啡销售系统,java项目 eclipse和idea都能打开运行 推荐环境配置:eclipse/idea jdk
您好!下面是一个使用Java代码在Eclipse中创建网页的示例,该网页可以根据输入的车牌号显示金额:
```java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class TruckParkTimeServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String truckNo = request.getParameter("truckNo");
String apiUrl = "http://10.198.8.102:8081/TruckParkTime?Token=Parking2023&TruckNo=" + truckNo;
// 发送HTTP GET请求获取接口返回结果
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuilder responseBuilder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
responseBuilder.append(line);
}
reader.close();
String apiResponse = responseBuilder.toString();
// 解析接口返回结果
String money = "";
if (apiResponse.contains("\"Money\":")) {
int startIndex = apiResponse.indexOf("\"Money\":") + "\"Money\":".length();
int endIndex = apiResponse.indexOf("\"", startIndex);
money = apiResponse.substring(startIndex, endIndex);
}
// 构建HTML响应
response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");
response.getWriter().println("<html>");
response.getWriter().println("<body>");
response.getWriter().println("车牌号:" + truckNo);
response.getWriter().println("<br>");
response.getWriter().println("金额:" + money);
response.getWriter().println("</body>");
response.getWriter().println("</html>");
} else {
// 处理请求失败的情况
response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
}
}
}
```
这是一个简单的Servlet,它接收GET请求并从指定的接口获取车辆信息。您可以将此代码添加到您的Java Web项目中,并在Eclipse中部署和运行该项目。请确保您的项目包含Servlet API库。
当您在浏览器中访问此Servlet时,可以通过URL参数`truckNo`传递车牌号,然后它将从接口获取金额并将其显示在生成的网页上。
请注意,这只是一个简单的示例,您可能需要根据实际需求进行修改和优化。
