我正在尝试使用Ethercard库将多个数据发送到网络服务器，但出于任何原因，一次只发送一个数据。
以下是我正在使用的代码：
#include <enc28j60.h>
#include <EtherCard.h>
#include <net.h>
#define HTTP_HEADER_OFFSET 163
#define MAX_STRINGS 100
#define MAX_STRING_LENGTH 8
/* Setup for Ethernet Library */
static byte mymac[] = { 0x74, 0x69, 0x69, 0x2D, 0x30, 0x31 };
const char website[] PROGMEM = "www.arksecurity.net16.net";
const char device[] = "0004";
char test[MAX_STRINGS][MAX_STRING_LENGTH+1];
unsigned long timer;
unsigned long tempo = 5000;
String register[20];
unsigned int sentOK = 0;
char* localID[MAX_STRINGS];
int countRegister = 2;
//int countRegister = 1;
int countID;
byte Ethernet::buffer[700];
void setup()
{
Serial.begin(57600);
register[0] = "empty";
if (!ether.begin(sizeof Ethernet::buffer, mymac, 53))
{
Serial.println("Failed to access Ethernet controller");
while(1);
}
else
Serial.println("Ethernet controller initialized");
Serial.println();
if (!ether.dhcpSetup())
{
Serial.println("Failed to get configuration from DHCP");
while(1);
}
else
Serial.println("DHCP configuration done");
if (!ether.dnsLookup(website))
{
Serial.println("DNS failed");
while(1);
}
else
Serial.println("DNS resolution done");
ether.printIp("SRV IP:\t", ether.hisip);
Serial.println();
timer = millis() - tempo;
}
void loop()
{
char tempRegister[80];
ether.packetLoop(ether.packetReceive());
if (millis() - timer > tempo)
{
timer += tempo;
ether.browseUrl(PSTR("/DevicesQuery.php?device="), device , website, response_callback);
if(test[0][0] != 0)
{
int missing = 0;
Serial.println("Data Received");
for(int i = 0; i < countID ; i++)
{
for(int x = 0; x < 8 ; x++)
{
if (test[i][x] == '\0')
{
missing = 1;
}
}
}
if(missing)
{
Serial.println("Data Missing");
tempo = 5000;
}
else
{
for(int g; g < countID ; g++)
{
register[g] = String(test[g]);
}
tempo = 40000;
}
}
else{
Serial.println("Waiting for server response...");
tempo = 5000;
}
//register[0] = "?ID=1234";
//register[1] = "?ID=5678";
if(register[0] != "empty")
{
for(int i = 0; i < countRegister ; i++)
{
register[i].toCharArray(tempRegister, 80);
//delay(5000);
//Serial.println(tempRegister);
ether.browseUrl(PSTR("/log.php"), tempRegister , website, browser_callback);
//while(sentOK == 0);
//sentOK = 0;
}
countRegister = 0;
register[0] = "empty";
}
}
}
static void response_callback (byte status, word off, word len) {
for(int i=0;i<MAX_STRINGS;i++)
for(int j=0;j<=MAX_STRING_LENGTH;j++)
test[i][j] = 0;
int i_string = 0;
int i_char = 0;
int i_ethBuff = off + HTTP_HEADER_OFFSET;
char carat;
countID = 0;
for (i_ethBuff = off + HTTP_HEADER_OFFSET; (carat = (char)Ethernet::buffer[i_ethBuff]) != 0; i_ethBuff++)
{
if (carat == '\n')
{ // New line char = new string
if (i_string < MAX_STRINGS - 1){
i_string++;
i_char = 0;
}
else
break; // Limite de memória do Arduino
}
else
{
if (i_char < MAX_STRING_LENGTH)
{
test[i_string][i_char] = carat;
i_char++;
} // otherwise discard the char (max length of string reached)
}
}
}
static void browser_callback (byte status, word off, word len)
{
Serial.println("Data sent");
//sentOK = 1;
}
countRegister是一个变量，当它等于1时，它工作得很好，但是，如果他等于2，他只会将第二个数据发送到服务器并忽略第一个数据。谁知道为什么会这样？
PS.:至于现在，我正在强制注册[0]，注册[1]值，正如你在上面的代码中看到的那样，但是想法是后来这些值来自外包。
