我正在尝试使用带有 GSM 屏蔽的 Arduino,使用他们的 REST API 通过 GPRS 将传感器数据发布到 www.parse.com。这就是他们的文档显示需要完成的方式:
curl -X POST \
-H "X-Parse-Application-Id: gmOpYot0OhWGnkMojjZv9KYUHMySCSeTGyyplArZ" \
-H "X-Parse-REST-API-Key: XQMA4Wd3SQdOsxudtKz5OdbPaVN3YE9aOKx0VSh2" \
-H "Content-Type: application/json" \
-d '{"Level":90, "Temp":25}' \

我需要在 Arduino 草图中以某种方式实现这一点。这是我的起点,因为它包括我的 shield 使用的库。此示例草图连接到 Google 并显示结果。我已经对其进行了测试,并且可以正常工作。
#include "SIM900.h"
#include <SoftwareSerial.h>
#include "inetGSM.h"
//#include "sms.h"
//#include "call.h"
//To change pins for Software Serial, use the two lines in GSM.cpp.
//GSM Shield for Arduino
//www.open-electronics.org
//this code is based on the example of Arduino Labs.
//Simple sketch to start a connection as client.
InetGSM inet;
//CallGSM call;
//SMSGSM sms;
char msg[50];
int numdata;
char inSerial[50];
int i=0;
boolean started=false;
void setup()
{
//Serial connection.
Serial.begin(9600);
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower.
if (gsm.begin(2400)){
Serial.println("\nstatus=READY");
started=true;
}
else Serial.println("\nstatus=IDLE");
if(started){
//GPRS attach, put in order APN, username and password.
//If no needed auth let them blank.
if (inet.attachGPRS("internet.wind", "", ""))
Serial.println("status=ATTACHED");
else Serial.println("status=ERROR");
delay(1000);
//Read IP address.
gsm.SimpleWriteln("AT+CIFSR");
delay(5000);
//Read until serial buffer is empty.
gsm.WhileSimpleRead();
// Change this bit!!
//TCP Client GET, send a GET request to the server and
//save the reply.
numdata=inet.httpGET("www.google.co.nz", 80, "/", msg, 50);
//Print the results.
Serial.println("\nNumber of data received:");
Serial.println(numdata);
Serial.println("\nData received:");
Serial.println(msg);
}
};
void loop()
{
//Read for new byte on serial hardware,
//and write them on NewSoftSerial.
serialhwread();
//Read for new byte on NewSoftSerial.
serialswread();
};
void serialhwread(){
i=0;
if (Serial.available() > 0){
while (Serial.available() > 0) {
inSerial[i]=(Serial.read());
delay(10);
i++;
}
inSerial[i]='\0';
if(!strcmp(inSerial,"/END")){
Serial.println("_");
inSerial[0]=0x1a;
inSerial[1]='\0';
gsm.SimpleWriteln(inSerial);
}
//Send a saved AT command using serial port.
if(!strcmp(inSerial,"TEST")){
Serial.println("SIGNAL QUALITY");
gsm.SimpleWriteln("AT+CSQ");
}
//Read last message saved.
if(!strcmp(inSerial,"MSG")){
Serial.println(msg);
}
else{
Serial.println(inSerial);
gsm.SimpleWriteln(inSerial);
}
inSerial[0]='\0';
}
}
void serialswread(){
gsm.SimpleRead();
}
我需要能够使用 App ID 和 API 密钥等将“Level”和“Temp”数据发布到 Parse.com,如上面的 API 示例所示。关于如何在草图中做到这一点的任何想法?
提前致谢!!
