人体红外传感器控制led灯

else
         gpio.write(led2,gpio.LOW);

1、Connect Wifi

Before we make a http-get request, connecting Wifi must be done.The demo gave by official website is as Code Block-1. See http://nodemcu.com/index_cn.html

2、PHP Webserver

By using php,we can get the request arguments by _GET['xxx'] directly. Demo is as  Code Block-2.

3、NodeMcu Request

Demo is as Code Block-3. We used the cjson module to parse the Json data returned by php server and iterate over and print  the elements.

4、Chinese Garbled Solution

Since the url of NodeMcu http-get request supports Chinese badly,we can use the Base64 encoded url. For example,  the base64 code of '你好' is '5L2g5aW9Cg==', then the url will be 'login.php?name=5L2g5aW9Cg=='. The php server should decode the data such as the Code Block-4.

上面是练英语写作的，欢迎吐槽。中文如下：

1、连接 Wifi

在进行Http 的GET请求前，我们需要连接Wifi.官方给出了一个例子,代码如下

连接Wifi代码Code Block-1:

参考 http://nodemcu.com/index_cn.html

2、PHP服务端

PHP服务端通过_GET['xxx']即可获取到GET请求参数。代码如下:

PHP服务端代码Code Block-2:

1. <?php  
2. $user_name = isset($_GET['name'])?$_GET['name']:null;  
3. $user_pwd = isset($_GET['pwd'])?$_GET['pwd']:null;  
4. $message = array(  
5.        "type"=>0,  
6.        "name"=>$user_name,
7.     "pwd"=>$user_pwd
   
8. );  
9. echo json_encode($message);   
10. ?>  

3、NodeMCU请求

代码如下，我们通过cjson模块来解析PHP服务端返回的Json数据并且遍历输出。

NodeMcu进行php.get请求代码Code Block-2:

4、中文参数乱码解决

NodeMCU对GET请求的URL参数中文支持并不好，我们可以使用Base64编码后的参数。比如说"你好"的base64编码为 ”5L2g5aW9Cg==“，那么url则为 “login.php?name=5L2g5aW9Cg==”，PHP服务端对base64参数的解析代码如下：

PHP解析base64编码参数Code Block-4:
