0.1 添加依赖
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.2</version> </dependency>
0.2 代码
//1. 打开浏览器 创建httpclient对象 CloseableHttpClient httpClient = HttpClients.createDefault(); //2. 输入网址 HttpGet httpGet = new HttpGet("http://www.baidu.com"); //3. 发送请求 CloseableHttpResponse httpResponse = httpClient.execute(httpGet); //4. 响应结果 HttpEntity httpEntity = httpResponse.getEntity(); //5. 解析结果 String result = EntityUtils.toString(httpEntity, "utf-8"); System.out.println(result);
1. 实操
1.1 添加依赖
1.1.1 找到 pom.xml 添加依赖
1.1.2 依赖代码
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.2</version> </dependency>
1.2 添加 TestHttpClient 类
1.2.1 创建类文件 com.aifu.TestHttpClient
1.2.2 添加代码
public static void main(String[] args) throws IOException { //1. 打开浏览器 创建httpclient对象 CloseableHttpClient httpClient = HttpClients.createDefault(); //2. 输入网址 HttpGet httpGet = new HttpGet("http://www.baidu.com"); //3. 发送请求 CloseableHttpResponse httpResponse = httpClient.execute(httpGet); //4. 响应结果 HttpEntity httpEntity = httpResponse.getEntity(); //5. 解析结果 String result = EntityUtils.toString(httpEntity, "utf-8"); System.out.println(result); }
