Question

我正在尝试使用AT命令在ESP8266上实现websocket，并发送以下命令：

AT+CIPSTART = "TCP","My_IP_Address", 80

回应没问题

AT+CIPSEND = length_of Data\r\n

回应是好＆GT;

GET ws://My_IP_Address/ HTTP/1.1
Origin: http://My_IP_Address\r\n
Connection: Upgrade\r\n
Host: My_IP_Address\r\n
Upgrade: websocket\r\n
\r\n

回应如下：

+IPD,325:HTTP/1.1 400 Bad Request
Server: nginx/1.10.2
Date: Sat, 05 Aug 2017 16:04:12 GMT
Content-Type: text/html
Content-Length: 173
Connection: close

<html>
<head><title>400 Bad Request</title></head>
<body bgcolor="white">
<center><h1>400 Bad Request</h1></center>
<hr><center>nginx/1.10.2</center>
</body>
</html>
CLOSED

GET / HTTP / 1.1 \ r \ n 主持人：My_IP_Address \ r \ n 连接：升级\ r \ n 升级：websocket \ r \ n \ r \ n

而不是获取ws：// My_IP_Address / HTTP / 1.1 来源：http://My_IP_Address 连接：升级\ r \ n 主持人：My_IP_Address \ r \ n 升级：websocket \ r \ n

...试
