在Java中设置GET请求的参数可以通过构建URL,并在URL中添加参数。下面是一个简单的示例代码:
import java.net.*;
import java.io.*;
public class Main {
public static void main(String[] args) {
try {
String urlString = "http://example.com/api";
String param1 = "key1=value1";
String param2 = "key2=value2";
URL url = new URL(urlString + "?" + param1 + "&" + param2);
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) {
e.printStackTrace();
}
}
}
在上面的示例中,我们首先构建了一个URL对象,将参数拼接在URL后面。然后使用HttpURLConnection打开连接,并设置请求方法为GET。最后读取响应内容并输出。
