我试图找到一种更优雅/内存占用更少的方法，通过分隔符拆分一个char数组。
字符数组:“192.168.178\nWifiSid\nWifiPassword\n123”
我愚蠢的分裂方式:
void convertPayload()
{
qrData = (char*)mypayload;
String ssidtmp = qrData;
ssidtmp.remove(qrData.indexOf("\n"), qrData.length()+1);
EEPROM.writeString(ssidAddr,ssidtmp);
EEPROM.commit();
String passtmp = qrData;
passtmp.remove(0, passtmp.indexOf("\n")+1);
passtmp.remove(passtmp.indexOf("\n"),passtmp.length()+1);
EEPROM.writeString(passAddr, passtmp);
EEPROM.commit();
String modulenrtmp = qrData;
modulenrtmp.remove(0, modulenrtmp.indexOf("\n") + 1);
modulenrtmp.remove(0, modulenrtmp.indexOf("\n") + 1);
modulenrtmp.remove(modulenrtmp.indexOf("\n") , modulenrtmp.length());
int modNRINT = modulenrtmp.toInt();
EEPROM.write(moduleNraddress, modNRINT);
EEPROM.commit();
String ftptmp = qrData;
ftptmp.remove(0, ftptmp.indexOf("\n") + 1);
ftptmp.remove(0, ftptmp.indexOf("\n") + 1);
ftptmp.remove(0, ftptmp.indexOf("\n") + 1);
ftptmp.remove(ftptmp.indexOf("\n") , ftptmp.length());
EEPROM.writeString(ftpAddr, ftptmp);
EEPROM.commit();
EEPROM.writeBool(configModeAddr, true);
EEPROM.commit();
//indicate QR succesfully read
blinkBurst(2, 300);
ESP.restart();
}
正如您所看到的，我正在创建不必要的字符串。 正确的做法是什么？
为您抽出时间干杯，谢谢！
如果可以编辑MyPayLoad，则可以使用std::strTok
void convertPayload() {
String ssidtmp = std::strtok(mypayload, "\n");
EEPROM.writeString(ssidAddr,ssidtmp);
EEPROM.commit();
String passtmp = std::strtok(nullptr, "\n");
EEPROM.writeString(passAddr, passtmp);
EEPROM.commit();
String modulenrtmp = std::strtok(nullptr, "\n");
int modNRINT = modulenrtmp.toInt();
EEPROM.write(moduleNraddress, modNRINT);
EEPROM.commit();
String ftptmp = = std::strtok(nullptr, "\n");
EEPROM.writeString(ftpAddr, ftptmp);
EEPROM.commit();
EEPROM.writeBool(configModeAddr, true);
EEPROM.commit();
//indicate QR succesfully read
blinkBurst(2, 300);
ESP.restart();
}
