[英]Validating User name and password
我正在嘗試使用 Arduino 板從 Web 服務器應用程序實現用戶名和密碼。 在下面的代碼中,我可以從用戶那里獲取用戶名和密碼。 現在的問題是如何比較結果比較。 如果用戶輸入名稱和密碼,它必須檢查並返回錯誤報告。
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,128);
EthernetServer server(80);
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
Ethernet.begin(mac, ip);
server.begin();
Serial.print("server is at ");
Serial.println(Ethernet.localIP());
}
void loop() {
// listen for incoming clients
EthernetClient client = server.available();
if (client) {
Serial.println("new client");
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
Serial.write(c);
if (c == '\n' && currentLineIsBlank) {
client.println("<!DOCTYPE html>");
client.println("<html>");
client.println("<body>");
client.println("</form>");
client.println("USER NAME:<input type='text' name='firstname'><br>");
client.println("PASSWORD:<input type='password' name='pwd'><br>");
client.println("<input type='submit'>");
client.println("</form>");
client.println("<body>");
client.println("</html>");
break;
}
if (c == '\n') {
// you're starting a new line
currentLineIsBlank = true;
}
else if (c != '\r') {
// you've gotten a character on the current line
currentLineIsBlank = false;
}
}
}
// give the web browser time to receive the data
delay(1);
// close the connection:
client.stop();
Serial.println("client disonnected");
}
}
