在Java中处理GET请求的异常可以使用try-catch语句来捕获和处理异常。以下是一个简单的示例:
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class HttpGetRequest {
public static void main(String[] args) {
try {
URL url = new URL("https://api.example.com/data");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println(response.toString());
} catch (Exception e) {
System.out.println("An error occurred: " + e.getMessage());
e.printStackTrace();
}
}
}
在上面的示例中,我们使用try-catch语句来捕获任何可能发生的异常,然后在catch块中打印错误消息并打印异常堆栈跟踪。您可以根据您的需求添加更多的异常处理代码,比如记录错误日志,返回特定的错误信息给客户端等。
