It seems the page rejects GETrequests that do not identify a User-Agent. I visited the page with a browser (Chrome) and copied the User-Agentheader of the GETrequest (look in the Network tab of the developer tools):
该页面似乎拒绝GET未标识User-Agent. 我使用浏览器（Chrome）访问了该页面并复制User-Agent了GET请求的标题（查看开发人员工具的网络选项卡）：
import requests
url = 'http://worldagnetwork.com/'
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36'}
result = requests.get(url, headers=headers)
print(result.content.decode())
# <!doctype html>

# <!--[if IE 7 ]><html class="no-js ie ie7" lang="en"> <![endif]-->

Just add to Alberto's answer:
只需添加阿尔贝托的答案：
If you still get a 403 Forbiddenafter adding a user-agent, you may need to add more headers, such as referer:
如果403 Forbidden添加a后仍然得到 a user-agent，则可能需要添加更多标题，例如referer：
headers = {
'User-Agent': '...',
'referer': 'https://...'
}
The headers can be found in the Network > Headers > Request Headersof the Developer Tools. (Press F12to toggle it.)
标题可以Network > Headers > Request Headers在开发者工具的 中找到。（按下F12以切换它。）

If You are the server's owner/admin, and the accepted solution didn't work for You, then try disabling CSRF protection (link to an SO answer).
如果您是服务器的所有者/管理员，并且接受的解决方案对您不起作用，请尝试禁用 CSRF 保护（链接到 SO 答案）。

我正在使用 Spring (Java)，因此设置要求您制作一个SecurityConfig.java包含以下内容的文件：

@Override

http.csrf().disable();
}
