I recently studied WeChat and found that it is not difficult. I borrowed the open source code of marker (www.yl-blog.com) and modified a few small bugs (I left a message on the author’s open source website, please see it for details). Open source website), the key logic will be realized quickly:
1. Developer verification
2. Customize the menu through the program interface
3. After the user pays attention, send a welcome message
4. According to the user Enter the topics you are interested in
5. Send file messages, send graphic messages
6. Use static web pages to simulate the simple template of the WeChat website

The public account, daydayup_it, is working nervously It is under planning and development and will be launched soon. The plan mainly provides some high-quality educational resources, so please pay attention.

I am going to sort out the key technologies when I have time and post them to communicate with everyone.

1. Developer verification, in fact, it mainly involves writing a Servlet. It is easy to handle with a little experience in web development

			} else {
				out.write("check error!");
			}
		}
		out.flush();
		out.close();
	}

2. Test the homepage effect and code of the WeChat website, using bootstrap to support media Query, when the mobile phone is viewed horizontally, the column will become a 2*2 layout, index.jsp, which requires the support of JSTL. You can also remove it yourself without affecting the effect. Just pay attention to the path of the connection file
