1.导入包
import java.net.URI;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
2.创建 httpclient 实例，并组装请求内容
public static void main(String[] args) {
HttpClient httpClient = HttpClients.createDefault();
try {
// 创建请求链接地址
URIBuilder uriBuilder = new URIBuilder("https://www.baidu.com");
// set 后加参数， ?language=**
uriBuilder.setParameter("language", "语言");
// 通过 builder 生成请求 uri
URI uri = uriBuilder.build();
// 创建 post 请求，或者 GET PUT
HttpPost request = new HttpPost(uri);
// 设置请求头
// 请求数据格式设置
request.setHeader("Content-Type", "multipart/form-data");
// 请求 OCP-APIM-订阅密钥 设置
request.setHeader("Ocp-Apim-Subscription-Key", "密钥");
// 请求体
StringEntity reqEntity = new StringEntity("请求体内容");
request.setEntity(reqEntity);
// 使用 httpclient 执行请求, 多态,返回请求结果
HttpResponse response = httpClient.execute(request);
// 请求状态
int code = response.getStatusLine().getStatusCode();
// 返回响应结果内容
HttpEntity entity = response.getEntity();
if (entity != null) {
// 请求内容字符串形式
String result = EntityUtils.toString(entity);
System.out.println(result);
}
} catch (Exception e) {
// TODO: handle exception
}
}
