以下是一个简单的示例,展示如何使用Apache HttpClient发送HTTP GET请求:
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
public class HttpClientExample {
public static void main(String[] args) {
try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
HttpGet request = new HttpGet("https://api.example.com/data");
try (CloseableHttpResponse response = httpClient.execute(request)) {
HttpEntity entity = response.getEntity();
if (entity != null) {
String result = EntityUtils.toString(entity);
System.out.println(result);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
通过以上步骤,你应该能够解决java.lang.NoClassDefFoundError: org/apache/http/message/BasicNameValuePair
错误。如果问题仍然存在,请检查是否有其他依赖冲突或类路径配置问题。
