安装

wget http://sourceforge.net/projects/webiopi/files/WebIOPi-0.7.1.tar.gz
tar xvzf WebIOPi-0.7.1.tar.gz

如果是以下型号的树莓派，一定要把下面的补丁文件复制到安装目录，先安装补丁，然后再执行setup.sh安装脚本。

修改密码

Change Password

The WebIOPi server uses an encrypted file that contains both login and password. To generate this file, simply run the webiopi-passwd command with sudo and follow instructions :

$ sudo webiopi-passwd
WebIOPi passwd file generator
Enter Login: webiopi
Enter Password: 
Confirm password: 

Hash: e70c940a189251e9cd4515b3a1a6c6f02aa05c744a456ce360fe14bf2c5c0353
Saved to /etc/webiopi/passwd

Then restart the default server :

$ sudo /etc/init.d/webiopi restart

去掉身份验证

Remove Protection

To remove login/password protection, you can ever remove /etc/webiopi/passwd or empty it, then restart the webiopi server.

webiopi-passwd syntax

$ webiopi-passwd -h
WebIOPi passwd file generator
Usage: webiopi-passwd [--help|file]
Compute and display hash used by WebIOPi for Authentication
Login and Password are prompted
    --help    Display this help
    -h
    file    Save hash to file

By default, the hash is saved in /etc/webiopi/passwd. Specifying a file allows to save the hash in another file, to use it with custom servers.

Auto start at boot

To setup your system to start webiopi at boot :

$ sudo update-rc.d webiopi defaults
To remove webiopi start from boot :

$ sudo update-rc.d webiopi remove

#   name   : used in the URL mapping
#   device : device name
#   args   : (optional) see device driver doc
# If enabled, devices configured here are mapped on REST API /device/name

[ROUTES]
# Custom REST API route syntax :
# source = destination
#   source      : URL to route
#   destination : Resulting URL
# Adding routes allows to simplify access with Human comprehensive URLs

# In the next example with have the bedroom light connected to GPIO 25
# and a temperature sensor named temp2, defined in [DEVICES] section
#  - GET  /bedroom/light       => GET  /GPIO/25/value, returns the light state
#  - POST /bedroom/light/0     => POST /GPIO/25/value/0, turn off the light
#  - POST /bedroom/light/1     => POST /GPIO/25/value/1, turn on the light
#  - GET  /bedroom/temperature => GET  /devices/temp2/temperature/c, returns the temperature in celsius
