I use the HttpClient methods:
我使用 HttpClient 方法：
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.methods.GetMethod;
like so:
像这样：
HttpClient client = new HttpClient();
HttpMethod method = new GetMethod("http://www.google.com");
int responseCode = client.executeMethod(method);
if (responseCode != 200) {
throw new HttpException("HttpMethod Returned Status Code: " + responseCode + " when attempting: " + url);
}
String rtn = StringEscapeUtils.unescapeHtml(method.getResponseBodyAsString());
EDIT: Oops. StringEscapeUtils comes from commons-lang. http://commons.apache.org/lang/api/org/apache/commons/lang/StringEscapeUtils.html
编辑：哎呀。StringEscapeUtils 来自 commons-lang。http://commons.apache.org/lang/api/org/apache/commons/lang/StringEscapeUtils.html

in addition to the pure Java answers by Quotidian and Yacoby you can try to execute the curl binary as in php. Check out how to use the ProcessBuilderclass.
除了 Quotidian 和 Yacoby 的纯 Java 答案之外，您还可以尝试像在 php 中一样执行 curl 二进制文件。查看如何使用ProcessBuilder该类。
