我正在尝试从URL中读取内容，但是我的程序不断出现此错误：
java.io.IOException: Server returned HTTP response code: 403 for URL: https://www.google.com/search?q=weather+in+seattle&oq=weather+in+sea&aqs=chrome.0.0l3j69i57j0l2.4686j0j4&sourceid=chrome&ie=UTF-8

线程“主”中的异常java.lang.NullPointerException 在Main.main（Main.java:25）
该如何解决？
