HTTPS连接服务器

本文档介绍了HTTPS连接服务器的大致流程，测试服务器为httpbin.org。

HTTPS连接服务器流程

创建证书文件

创建一个文件

AT+FSCREATE=<filename>

参数：<filename> 文件名

写入CA证书

AT+FSWRITE=<filename>,<mode>,<filesize>,<inputtime>

参数：

<filename> 文件名

<mode>　　 ０　　从头写文件　　　１　　从尾写文件

<filesize>　 要写入的数据长度　注：不能超过10240个字节

<inputtime> 输入持续的时间

PDP上下文激活

设置 GPRS 承载类型

AT+SAPBR=3,1,"CONTYPE","GPRS"

配置 APN 参数

AT+SAPBR=3,1,"APN","" 

激活 GPRS PDP 上下文

AT+SAPBR=1,1

检查承载状态

AT+SAPBR=2,1

设置证书文件

HTTP协议栈初始化

AT+HTTPINIT  

启用SSL

AT+HTTPSSL=1

设置服务器CA 证书

AT+SSLCFG="cacert",153[,<cacertpath>]

参数：<cacertpath> 证书文件路径

YM310 X09

连接服务器

设置HTTP会话参数：CID

AT+HTTPPARA="CID",1

设置HTTP会话参数：URL

AT+HTTPPARA="URL","https://xxx.xxx"  

HTTPS GET/POST

GET请求

AT+HTTPACTION=0

POST请求

AT+HTTPACTION=1 

POST写数据

AT+HTTPDATA=<size>,<time>

参数：

<size> POST数据的大小

<time> 输入数据的最长时间

读取从HTTP 服务器GET的数据

AT+HTTPREAD

关闭连接

结束HTTP服务

AT+HTTPTERM

HTTPS GET
