如何在Get请求中以正确的格式从RTC向网站发送时间戳?使用arduino

您好我一直在尝试将数据从我的arduino发送到我的ASP.Net网站并且已经成功,直到我尝试在GET请求中将时间戳作为变量发送。

这是因为asp.net期望:01/01/01 01:01:01并且发送1/1/1 1:1:1。所以我需要弄清楚如果需要,如何将它与前面的零一起发送

到目前为止我的arduino代码(发送部分)

void sendLightData() {
  DateTime now = rtc.now();
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // no point in carrying on, so do nothing forevermore:
    // try to congifure using IP address instead of DHCP:
    Ethernet.begin(mac, ip);
  }
  // give the Ethernet shield a second to initialize:
  delay(1000);
  Serial.println("connecting...");

  // if you get a connection, report back via serial:
  if (client.connect(server, 80)) {
    Serial.println("connected");
    // Make a HTTP request:
    client.print("GET /LightData.aspx?uname=");
    client.print(userName);
    client.print("&pword=");
    client.print(password);
    client.print("&LStatus=");
    client.print(lightStatus);
    client.print("&LHeight=9&");
    client.print("timestamp=");
    client.print(now.day(), DEC);
    client.print("/");
    client.print(now.month(), DEC);
    client.print("/");
    client.print(now.year(), DEC);
    client.print("%20");
    client.print(now.hour(), DEC);
    client.print(":");
    client.print(now.minute(), DEC);
    client.print(":");
    client.print(now.second(), DEC); 
    client.println(" HTTP/1.1");
    client.println("Host: www.auntieagie.eu");
    client.println("Connection: close");
    client.println();
    // this works if entered into a browser (trying to replicate in arduino) http://auntieagie.eu/LightData.aspx?uname=test&pword=t&LStatus=1&LHeight=2&timestamp=21/02/2014%2001:01:01
  } 

任何帮助或正确方向上的一点都会很棒

1 个答案:

答案 0 :(得分:0)

试试这个:

client.print(now.Date.ToString().Replace(" ", "%20"));

这将返回一个dd / mm / yyyy hh:mm:ss用编码字符替换空格。

至少在Asp Net中你有HttpUtility,如果你有权访问它,你可以使用: System.Web.HttpUtility

client.print(HttpUtility.UrlEncode(now.Date.ToString()));

日和月将返回一个Int值,因此,不包括左零。
