This article will develop weather queries that everyone cares about every day. for example, if a user sends a message "Huanggang weather", the user will return the real-time weather conditions of Huanggang, and the weather conditions in the next two or even five days. This article will develop weather queries that everyone cares about every day. for example, if a user sends a message "Huanggang weather", the user will return the real-time weather conditions of Huanggang, and the weather conditions in the next two or even five days.

Recently, a project needs to add the weather forecast function to the public account, and use the weather query function in IoV API V3.0 provided by Baidu to achieve the following:

Step 3: compile jiekou. php in the public platform interface file

Notes

The value of the TOKEN in the public platform must be consistent with that in the self-compiled interface file.

To compile php code, you must use professional php editing tools, such as EditPlus and Dreamweaver.

In the preceding weather interface file, the Baidu IOV api AK code has been changed to "self-applied Baidu iov api ak code: Please fill in the code after applying.
