idea建httpclient

以下是在IntelliJ IDEA中使用httpclient的步骤：

1.打开IntelliJ IDEA，创建一个新的Java项目。

2.在项目中创建一个新的Java类。

3.在Java类中导入httpclient的依赖包，例如：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
</dependency>

4.在Java类中编写httpclient的代码，例如：

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class HttpClientExample {
    public static void main(String[] args) throws IOException {
        HttpClient client = HttpClientBuilder.create().build();
        HttpGet request = new HttpGet("https://jsonplaceholder.typicode.com/posts/1");
        HttpResponse response = client.execute(request);

        BufferedReader bufReader = new BufferedReader(new InputStreamReader(
                response.getEntity().getContent()));

        StringBuilder builder = new StringBuilder();
        String line;
        while ((line = bufReader.readLine()) != null) {
            builder.append(line);
            builder.append(System.lineSeparator());
        }
        System.out.println(builder);
    }
}

5.运行Java类，即可看到httpclient发送请求并接收响应的结果。
