HTTP使用流程
AT+HTTPCREATE="http://iot.10086.cn/" 创建 http 实例，可指定 URL，除 HTTP 标识和域名外，其他 URL 部分将被忽略
+HTTPCREATE:0 模组返回 httpclient id:0
OK
AT+HTTPHEADER=0,"User-Agent: Unkown\r\nConnection: close\r\n" 配置 HTTP 头部，注意 HTTP 协议规定
每个头部字段之间有回车换行分隔，部分 HTTP 服务器要求配置 User-Agent 字段，不然会拒绝响应
OK
AT+HTTPSEND=0,0,"/page/index/name/culture" 发送 GET (method 参数为 0)请求包，URL 资源绝对
路径“/page/index/name/culture”
OK 模组收到发送请求
CONNECT OK 连接服务器成功

**注意**:如果模组接收数据时出现+HTTPDROP:0,1460 上报，说明模组接收缓冲区满引起数据 drop，数据丢失后将出现后续接收过程解析错误，请检测当前是否波特率较低影响数据交互，如 M5310-A 使用+NATSPEED 将波特率调高至 115200 或 230400(波特率高于 9600 会自动禁止模组进入PSM)，HTTP 功能使用完毕之后调回较低波特率以恢复使能 PSM 的状态.

### 2.1 OneNET HTTP API 应用举例
API 使用说明请参考 OneNET 文档中心>>资源下载>>1.1 说明文档>>NB-IoT 协议设备开发文档
https://open.iot.10086.cn/doc/art398.html#97
本段仅举例创建设备与即时读设备资源命令
##API-创建 LWM2M 设备##
AT+HTTPCREATE="http://api.heclouds.com/"
+HTTPCREATE:0 OK
at+httpheader=0,"api-key:ChangeForYourOwnKey\r\nContent-Type:application/json\r\nConnection: Close\r\n"
APIKey 需替换为实际值
OK
at+httpcontent=0,"{"title": "865820030265172"\x2C"desc": "865820030265172"\x2C"protocol": "LWM2M"\x2C"auth_info": {"865820030265172": "460043783403288"}}"
",为 AT 参数分隔符，需要转义处理，不然命令解析会出现异常，使用当前设备 IMEI/IMSI 注册
OK
AT+HTTPSEND=0,1,"/devices" 发送 post 请求，创建设备
OK

+HTTPNMIH:0,0,148 读设备资源 HTTP API 返回 HTTP 数据头

Content-Type: application/json;charset=UTF-8 Transfer-Encoding: chunked

回复 READ 上报值
{"errno":0,"error":"succ","data":[{"res":[{"val":false,"res_id":5500},{"val":-
12,"res_id":5501},{"val":"test","res_id":5750}],"obj_inst_id":0}]}
+HTTPNMIC:0,0,144,144,0
+HTTPDISCON:0 HTTP 连接断开
AT+MIPLCLOSE=0 关闭 OneNET 连接
OK AT+MIPLDELETE=0
OK
注
当 IMEI 已被注册时将返回注册错误；即时读设备资源命令当设备不在线将返回设备不在线
当设备长时间不与平台通信可能引起路由信息老化或处于休眠模式时而无法收到平台下发的数据； 当一定时间后未回复响应 API 将返回读取超时(unsuccess: TIME_OUT)
其他注意事项请参考 OneNET 平台 API 手册
以上过程仅用于展示 HTTP 操作示例，实际运用中应在客户服务端使用 OneNET API 控制模组进行相应动作
创建设备 HTTP API 中需要在Content 字段输入 json 字符串，由于 json 字符串中存在 AT 命令解析中会被错误识别的双引号+逗号(”,)，需要将逗号转义，及前文使用的方法，也可在不影响服务器解析的情况下在逗号前插入换行符避免；或者全文使用十六进制转换后输入；+HTTPSEND 命令暂不支持此操作，请尽量将此类数据放入 content 或者 header 字段上传
**举例如下**
at+httpcontent=0,"{"title": "865820030265172"\r,"desc": "865820030265172"\r,"protocol": "LWM2M"\r,"auth_info":
