使用AT命令的POST api Rest - SIM800

Question

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

下面是我的命令序列：

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

在此之前，一切看起来都很好，但当我在服务器中记录post请求时，我得到的是：

+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

它看起来像是在不带正文的情况下发布\n

为什么我的帖子主体有headers参数？

Answer 1

这就是我在sim900调制解调器上尝试的方法{"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

Answer 2

我不是专家，但在我的sim900调制解调器上我试过了，它对我很有效。

初始化调制解调器以进行数据传输的AT命令

AT+HTTPINIT

AT+HTTPPARA="CID",1

AT+HTTPPARA="URL","myhost/deviceRegister"

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

AT+HTTPDATA=94,120000

OK

DOWNLOAD

Content-Length:13

{"IMEI":"aa"}

AT+HTTPACTION=1

AT+HTTPREAD

希望这对你有所帮助
