需要自己设置 bduss，bduss 设置方法：
登录百度后在首页按 F12，在调试窗口左上角 Filter 中填 www.baidu.com
在 Headers 选项卡中 Request Headers 中找到 BDUSS= 复制其后的字符 赋值给代码中的 bduss 即可
所需依赖：
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.8</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpcore</artifactId> <version>4.4.6</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.8.1</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.58</version> </dependency>
或者直接用 commons-httpclient 的依赖，commons-httpclient 包含 httpclient 与 httpcore 包里部分内容
<dependency> <groupId>commons-httpclient</groupId> <artifactId>commons-httpclient</artifactId> <version>3.1</version> </dependency>
如果你使用普通导 jar 包的 Java 项目，则需要的 jar 包除了以上之外还需要的 jar 有：commons-logging、commons-codec，可自行在 Maven 仓库下载
