http - 使用 AT 命令的 POST api Rest - SIM800

Question

我在使用 AT 通过 SIM800 模块发送后置参数时遇到问题。当我使用 FTDI 和 mac 屏幕应用程序终端时。

这是我的命令序列:

AT+HTTPINIT
AT+HTTPPARA="CID",1
AT+HTTPPARA="URL","myhost/deviceRegister"
AT+HTTPPARA="CONTENT","application/json"
AT+HTTPDATA=94,120000
OK

DOWNLOAD
POST deviceRegister HTTP/1.1
Host: myhost
Content-Length:13

{"IMEI":"aa"}
AT+HTTPACTION=1
AT+HTTPREAD

到这里为止，一切看起来都很好，但是当我在我的服务器中记录我的发布请求时，我所拥有的是:

+HTTPREAD: 259
POST deviceRegister HTTP/1.1
Host: myhost
Accept: */*
Connection: Keep-Alive
Content-Type: application/json
User-Agent: SIMCOM_MODULE
Content-Length: 94


{"IMEI":"aa"}gister HTTP/1.1

OK

它看起来像是在没有\n的情况下发布到正文

为什么我的帖子正文有标题参数？

这就是我在我的 sim900 调制解调器上试过的{"myvar1="myvalue1","myvar2"="myvalue2"} 是我的 json 对象

AT+CGATT?

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

AT+SAPBR=3,1,"APN","mynetworkprovider.com"

AT+SAPBR=3,1,"USER","mylogin"

AT+SAPBR=3,1,"PWD","mypassword"

AT+SAPBR=1,1

AT+HTTPINIT

AT+HTTPPARA="CID",1

AT+HTTPPARA="URL","http://myserveraddress/comm.php"

AT+HTTPPARA="CONTENT","application/json"

AT+HTTPDATA=137,5000 **=>SIM response : DOWNLOAD**

Content-Length: 414

{"myvar1="myvalue1","myvar2"="myvalue2"}


AT+HTTPACTION=1

AT+HTTPREAD =>should respond 200 http ok status
