WeChat public account development complete tutorial 2-PHP Tutorial-php.cn

This article introduces the second complete tutorial on WeChat public account development. It has certain reference value. Now I share it with everyone. Friends in need can refer to it

because of work needs , in the past two years, there have been many projects on WeChat public accounts and mini programs. That’s why I plan to write a comprehensive production tutorial. Of course, the best tutorial is the documentation of the WeChat work platform. I'm just going to talk about the production process in my work here. I host the source code of all related articles on my own github. Welcome to follow: Address Click to open the link. Let's start our tutorial.

In the first section above, I talked about turning on the developer mode and simply obtaining the access_token and caching it, as well as simple testing. We will not do this for the time being. You need to use the parameters of this

access_token. Most of the time, we will first talk about that part of our test code and improve it: (I will introduce technologies such as Baidu Maps and Turing Robots), because the company develops We use this technology when we are working, so I will tell you about it: Start:

1. Message acceptance:

When receiving a message, WeChat will send the message according to the user's content. Divide. There are text messages, picture messages, language messages, videos, connections and other messages respectively. When a user interacts with a message on the public platform, each message will request a customized URL address. During the request process, various parameters are transmitted using the xml format. Accepting a message means obtaining relevant data from the WeChat request process.

Variable substitution used in the code uses PHP functions

sprintf

##Everyone You can check it out. Its function is nothing more than to allow variables to be replaced in sequence.

1.1. Accept text messages:

The format is as above: the code is as follows : Text template

#// Text template

$textTpl = "<xml>
                            <ToUserName><![CDATA[%s]]></ToUserName>
                            <FromUserName><![CDATA[%s]]></FromUserName>
                            <CreateTime>%s</CreateTime>
                            <MsgType><![CDATA[%s]]></MsgType>
                            <Content><![CDATA[%s]]></Content>
                            <FuncFlag>0</FuncFlag>
                            </xml>";

In summer, you must try shooting a rainbow Jul 21, 2024 pm 05:16 PM

After rain in summer, you can often see a beautiful and magical special weather scene - rainbow. This is also a rare scene that can be encountered in photography, and it is very photogenic. There are several conditions for a rainbow to appear: first, there are enough water droplets in the air, and second, the sun shines at a low angle. Therefore, it is easiest to see a rainbow in the afternoon after the rain has cleared up. However, the formation of a rainbow is greatly affected by weather, light and other conditions, so it generally only lasts for a short period of time, and the best viewing and shooting time is even shorter. So when you encounter a rainbow, how can you properly record it and photograph it with quality? 1. Look for rainbows. In addition to the conditions mentioned above, rainbows usually appear in the direction of sunlight, that is, if the sun shines from west to east, rainbows are more likely to appear in the east.

Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent Apr 07, 2024 am 09:10 AM

On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A
