HTTPClient的使用

引入

在pom.xml插入：

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

使用

public static String doGet(URL url) throws Exception {
    String content;
    HttpHost proxyHost = new HttpHost("127.0.0.1",7890);
    DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxyHost);
    CloseableHttpClient httpclient = HttpClients.custom()
            .setRoutePlanner(routePlanner)
            .build();
    HttpGet httpGet = new HttpGet(url.toString());
    CloseableHttpResponse response = null;
    try {
        
        response = httpclient.execute(httpGet);
            content = EntityUtils.toString(response.getEntity(), "UTF-8");
            System.out.println("内容长度：" + content.length());
            return content;

    } finally {
        if (response != null) {
            response.close();
        }
        httpclient.close();
    }

}
