使用Java编写的HTTP客户端示例错误解析

在Java中编写一个HTTP客户端，处理错误解析可以按照以下步骤进行：

引入必要的库：

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

创建HTTP请求方法（GET/POST等）：

public static void sendGetRequest(String url) {
 try {
     // 构建URL对象
     URL obj = new URL(url);
     // 打开连接并获取输入流
     HttpURLConnection con = (HttpURLConnection) obj.openConnection();
     con.setRequestMethod("GET");
     // 读取响应数据
     int responseCode = con.getResponseCode();
     BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream())));
     // 处理读取到的数据（这里简单显示前几行）
     String inputLine;
     StringBuilder contentBuilder = new StringBuilder();
     while ((inputLine = in.readLine()) != null) {
         contentBuilder.append(inputLine);
     }
     System.out.println("Response Code: " + responseCode);
     System.out.println("Response Content: " + contentBuilder.toString());
 } catch (Exception e) {
     // 处理异常，这里简单打印错误信息
     System.err.println("Error occurred while sending GET request.");
     System.err.println(e.getMessage());
 }
}
